Child Support Calculator in North Carolina: What You Should Know
North Carolina uses the Income Shares Model with gross income as the base. Its guidelines, adopted under N.C. Gen. Stat. § 50-13.4(c1), include separate worksheets for primary custody (Worksheet A), shared custody where each parent has the children for at least 123 overnights (Worksheet B), and split custody where each parent has primary custody of at least one child (Worksheet C). Worksheet B produces lower support amounts than Worksheet A for the same incomes, reflecting the direct costs each parent bears when children spend substantial time in both homes. The word to read closely there is each. Both parents have to reach 123 nights, so a parent with 250 overnights leaves the other with 115 and the case is not shared custody at all. Moving well past an even split can cost you the worksheet that an even split would have given you.
Key point: North Carolina's Worksheet B applies when each parent has at least 123 overnights a year, roughly 34 percent of the calendar. Because both parents have to clear that line, a schedule well past 50/50 can put a case back on the primary-custody worksheet.

How North Carolina calculates child support
North Carolina sets child support with the Income Shares Model, and we have read the guideline that says so, which means both parents' incomes are combined, and each parent covers the share of the total obligation that matches their share of that combined income. Here is what that looks like in practice.
Calculated from the state's published guideline
North Carolina is calculated from the state's own guidelines. The basic obligation on this page is read from the North Carolina Schedule of Basic Support Obligations, all 774 rows of it, transcribed from the published document and checked against an independent reading of the same table before it went live. The parenting-time rule, the shared-custody threshold, the minimum order and the point where the schedule stops are the state's own, taken from the same document, which is linked below. Where the guidelines direct interpolation between two rows, we interpolate; where they say the schedule does not apply at all, we say so instead of returning a number.
The self-support reserve is computed too, and it is worth knowing how it works because it is not a discount. North Carolina shades the low-income rows of its schedule, and where the paying parent's adjusted gross income falls in that shaded band and the case runs on Worksheet A, the guidelines direct a different calculation rather than a reduced one: the obligation is read from the schedule on the paying parent's income alone rather than on both parents' combined income, and childcare and health insurance premiums are left out of it. The band ends at $1,750 a month for one child and rises to $3,450 for six. The reserve behind it is built on the 2022 federal poverty guideline of $1,133 a month for one person, and North Carolina holds it at that year until it reissues the schedule, so it will not match the current federal figure and is not supposed to.
Shading does not survive text extraction from a PDF, so those six boundaries were read off the printed document by eye, and a visual read is the weakest evidence on this page. We did not leave it there. Inside the shaded band every column of the schedule we already hold climbs at a near-constant rate, and at the first unshaded row that rate breaks sharply and never returns. Deriving the boundary from the numbers alone gives the same six figures as reading the shading, in all six columns, and the test suite asserts it on every build.
One limit we will not paper over. The guidelines say the reserve is not applied on Worksheet B, the shared-custody worksheet, so those cases run the ordinary way on combined income with childcare and insurance included. But the schedule prints a single figure per cell, and in the shaded rows that figure already has the reserve built into it, with no unadjusted version published anywhere. Where a shared-custody case's combined income is itself low enough to land in the shaded band, we are reading a reserve-shaped value in a situation where the guidelines switch the reserve off, and the document does not say what to read instead. It is a narrow case and we flag it on the result rather than quietly choosing a reading.
Source: N.C. Gen. Stat. § 50-13.4(c1)
The Income Shares Model starts from an estimate of what the children would have received had the household stayed intact, then splits that figure between the parents. The calculation runs in three steps. Both parents' monthly incomes are added together. A basic support obligation for that combined figure and that number of children is set by the state's own guideline. Each parent is then responsible for the percentage of the obligation that matches their percentage of the combined income.
Because the obligation is divided by income share rather than assigned to one side, the receiving parent's earnings matter as much as the paying parent's. A parent bringing in 70 percent of the combined income carries roughly 70 percent of the total obligation. The parent the children live with most is treated as already spending their share through daily care, so only the other parent's share is ordered as a payment. That is why closing the income gap between two parents lowers the payment even when neither parent's own income falls.
Four things are then layered on top of the base figure: health insurance premiums covering the children, work-related childcare, support already being paid under an earlier order for other children, and, in most states, the number of overnights each parent has.
The figure North Carolina's own guideline works from is combined adjusted gross income, under the Schedule of Basic Child Support Obligations, adopted under N.C. Gen. Stat. § 50-13.4(c1).
What moves the number in North Carolina
- Both parents' monthly incomes, and the gap between them
- Number of children covered by the order
- The paying parent's share of overnights
- Health insurance premiums covering the children
- Work-related childcare paid for the children
- Support already ordered for children from another relationship
Income limits and judicial discretion
North Carolina sets a line and it is the strongest form of one on this site, which is that above it the guidelines decline to answer. The Schedule of Basic Support Obligations stops at $40,000 of combined adjusted gross monthly income, $480,000 a year, and the guidelines say in terms that above that point "the supporting parent's basic child support obligation cannot be determined by using the child support schedule". So there is no guideline figure for a family over the line. Support is set instead on the reasonable needs of the child for health, education and maintenance, weighed against the estates, earnings, conditions and accustomed standard of living of the child and the parties, under the first sentence of G.S. 50-13.4(c). The guidelines add that the schedule "may be of assistance to the court in determining a minimal level of child support", and that is exactly what this page shows above the line: the top row, offered as a floor rather than as an estimate of the order. North Carolina gives judges a moderate amount of room on custody and parenting time, so expect the order to start from the guideline figure and move with the facts of the case.
North Carolina child support examples
These three examples run through the same North Carolina calculator on this page, so the figures match what the tool returns for the same entries. Each example changes one thing against the one before it, so you can see which lever moved the result. All three assume a standard schedule of 80 overnights a year with the paying parent, and North Carolina's own parenting-time rule is applied to every figure below rather than left off it. At this count the rule does not reach, so these are complete guideline amounts rather than amounts waiting for an adjustment. The table further down the page is where the count starts to move the number, and it shows where.
Example 1: One child, standard schedule
The starting point: one child, a moderate income gap, and no insurance or childcare in the order yet.
- Paying parent
- $5,000/mo
- Other parent
- $3,000/mo
- Children
- 1
- Overnights
- 80/yr
Guideline result: $720 per month ($8,640 a year).
| Step | Amount |
|---|---|
| Your gross monthly income | $5,000 |
| Other parent's gross monthly income | $3,000 |
| Combined adjusted gross income | $8,000 |
| Basic support obligation (1 child) | $1,152 |
| Your share by income (63%) | $720 |
- With 80 overnights a year you are below North Carolina's 123-night shared-custody threshold, so support is calculated on Worksheet A and no parenting-time adjustment applies. The adjustment switches on at 123 nights, but only if the other parent also has at least 123.
- North Carolina's basic obligation already includes $250 per child per year for uninsured medical and dental costs, so that amount is not added on top of this figure. Only uninsured health care costs above $250 per year may be ordered separately, and that is a decision for the court.
- One thing North Carolina makes easier than most states on this site, and one thing it does not. The schedule is read at "adjusted gross income", and the guidelines are unusually direct about what that is not: "Gross income is income before deductions for federal or state income taxes, Social Security or Medicare taxes, health insurance premiums, retirement contributions, or other amounts withheld from income." The tax is built INTO the schedule instead, which the same page says was "based upon net income converted to gross annual income by incorporating the federal tax rates, North Carolina tax rates and FICA". So there is no converting your pay to a net figure and no substituting one for the other, and unlike most states here North Carolina does not deduct alimony you pay either. What the guidelines do subtract, and this form collects only for you rather than for both of you, is current child support you actually pay under an existing order. What it cannot collect at all is a deduction for your own other children who currently live with you, which the guidelines set at the basic obligation for those children read at your income alone; and anything the OTHER parent pays under an existing support order, which this form asks about only for you. Neither can raise anybody's adjusted gross income, and North Carolina's schedule never falls as income rises, so the basic obligation your calculation starts from is HIGHER than a North Carolina court would reach wherever either applies.
- Your share of that obligation is the part we cannot put a direction on, and in North Carolina it can move the wrong way for two separate reasons. The first is the ordinary one: the worksheet splits the obligation by each parent's share of combined income, so if it is the OTHER parent who pays under an earlier order or supports a child at home, the combined figure falls and your share of what is left grows. The second is North Carolina's own, and it surprises people. Below the shaded rows of the schedule the guidelines do not discount the ordinary calculation, they replace it: the obligation is read on the paying parent's income alone and that parent carries the whole of it. A deduction that takes you into that band, or under the $1,150 line where a flat $50 order applies, can therefore raise the amount rather than lower it. We measured that: it happened in 71 of the 3,024 households where only the reader had a deduction. The obligation being shared is too high in every case; the share of it is the part we cannot put a direction on.
- One date worth carrying away with the figure. North Carolina's guidelines are not in the statute: G.S. 50-13.4(c1) hands the whole subject to the Conference of Chief District Judges and requires them to review it at least every four years. The edition behind everything above is AOC-A-162, Rev. 1/23, effective January 1, 2023, and the next review is running now, with the comment window closed on May 25, 2026. On the last two cycles a new edition took effect on the following January 1. That review covers the substantive provisions in the first six pages of the guidelines as well as the schedule, which is where the income definition, the deductions and the self-support reserve all sit, so this is not only a question of whether the dollar figures move. If you are reading this in 2027 or later, check the current edition before relying on the amount.
- The employment status you selected has not changed the estimate above. You had to answer to get here, and whichever answer you picked the figure is the same: we calculate on the income figures you entered and impute nothing to either parent. Courts can impute. Where a judge finds a parent voluntarily unemployed or under-employed, a court may set support on what that parent could earn rather than on what they currently bring in, and an imputed figure is set at or above actual earnings rather than below them. Which way that would move your case depends on whose income gets imputed, and that is the part we cannot answer for you: if it is the paying party's, the figure above tends to sit below what a court would order, and if it is the receiving party's it can move in either direction depending on the state and on the two incomes, so we do not put a direction on it. We have read the imputation provision in Illinois and in no other state, North Carolina included, so nothing on this page is adjusted for one.
Example 2: Two children, same incomes
Identical to the first example except for a second child, which isolates what the second child is worth in this state.
- Paying parent
- $5,000/mo
- Other parent

- Overnights

Example 3: Two children, higher-earning paying parent, insurance and childcare
The paying parent now earns considerably more, and carries the health insurance and work-related childcare, which are credited back against the obligation.
- Paying parent
- $12,000/mo
- Other parent
- $3,000/mo
- Children
- 2
- Overnights
- 80/yr
Guideline result: $1,784 per month ($21,408 a year).
| Step | Amount |
|---|---|
| Your gross monthly income | $12,000 |
| Other parent's gross monthly income | $3,000 |
| Combined adjusted gross income | $15,000 |
| Basic support obligation (2 children) | $2,463 |
| Work-related childcare added | $650 |
| Children's health insurance premium added | $280 |
| Total support obligation | $3,393 |
| Your share by income (80%) | $2,714 |
| Credit: childcare and insurance you pay directly | -$930 |
- With 80 overnights a year you are below North Carolina's 123-night shared-custody threshold, so support is calculated on Worksheet A and no parenting-time adjustment applies. The adjustment switches on at 123 nights, but only if the other parent also has at least 123.

Comparing the first two examples shows what a second child is worth in North Carolina: the order moves from $720 to $1,079a month on identical incomes. The third example raises the paying parent's earnings and adds health insurance and childcare, which are credited back against the obligation rather than added on top of it.
How parenting time changes support in North Carolina
North Carolina adjusts support for parenting time, and we compute the adjustment, because we have read the rule out of the state's own published guidelines rather than inferring it. The mechanism is a cliff. Below 123 overnights the calculation runs on Worksheet A and parenting time does not enter it at all. At 123 overnights it switches to Worksheet B, which increases the combined basic obligation by 50 percent, splits it between the parents by income, and then weights each parent's share by the proportion of the year the children spend with the other parent. The two figures are offset and the parent with the higher one pays the difference. The figure steps at that boundary rather than sliding toward it, so a single night can be worth several hundred dollars a month.
The part that catches parents out is that BOTH parents have to clear 123 overnights, not just the one asking for the adjustment. Under N.C. Gen. Stat. § 50-13.4(c1) the shared route turns on a child living with each parent for at least 123 nights a year. Work that through and the result is genuinely counter-intuitive, and you can see it in the last row of the table above. A parent with 250 overnights leaves the other parent 115, 32 percent of the year, which is below the bar, so the shared route never comes out and the figure goes back up to about where it was at 52 overnights. Getting well past an even split can cost you the adjustment an even split would have given you. If you are negotiating toward a particular number of overnights, check what the schedule leaves the other parent, not only what it gives you.
Note the wording of the boundary, because it is not the same in every cliff state and it decides cases that sit on it. North Carolina's rule is a child living with each parent for at least 123 nights a year, so a parent at exactly 123 qualifies. Other states word the same kind of rule as "more than", which excludes a parent sitting exactly on the number: West Virginia's threshold is 127 days and a parent with exactly 127 does not clear it. One night either side of a threshold is where contested schedules tend to end up, so it is worth reading your own state's phrasing rather than a summary of it.
Two further North Carolina rules are worth knowing before you read the number above. The basic obligation already includes $250 per child per year for uninsured medical and dental costs, so that is not an extra to be added on top; only uninsured costs above that figure may be ordered separately. And health insurance for the children is treated as reasonable only up to 5 percent of a parent's gross income, so a premium above that may not be credited in full.
Overnights are the second biggest lever after income, and they are the one parents most often underestimate. The reasoning is straightforward: a parent who has the children a third of the year is already paying for food, utilities, and a bedroom during that time, so the transfer payment to the other household falls to avoid charging twice for the same costs.
The table below runs one family through the North Carolina guideline at 6 parenting-time levels. Income is held at $5,000 and $3,000 a month with two children, so the only thing changing between rows is the number of overnights. It follows North Carolina's own published rule, and the state's worksheet linked below is still the document a court works from.
| Overnights | Arrangement | Monthly support | Change |
|---|---|---|---|
| 52 (14%) | Alternating weekends only | $1,079 | Baseline |
| 80 (22%) | Alternating weekends plus a midweek night | $1,079 | Baseline |
| 110 (30%) | Extended weekends and half of school breaks | $1,079 | Baseline |
| 146 (40%) | A 5-2-2-5 rotation, about 40 percent of nights | $583 | -$496 |
| 182 (50%) | Equal time, week on and week off | $327 | -$752 |
| 250 (68%) | The children with you most of the year, alternating weekends with the other parent | $1,079 | Baseline |
The size and the shape of that movement are what parenting-time disputes and support disputes are usually arguing about at the same time, in different clothing.
Where North Carolina starts on parenting time
North Carolina does not presume equal parenting time. That is our own record rather than North Carolina's own custody law. Courts decide the schedule on the best interests of the children, so the overnight count is established case by case rather than assumed. Parents who expect substantial time should treat it as something to be negotiated deliberately, and the section above is what North Carolina's own guidelines do with the count you end up with, which is worth reading before you agree to one.
Our record has North Carolina requiring mediation before a contested custody hearing, typically around $225 a session. That is our own record rather than North Carolina's own court rules. Because the parenting schedule that comes out of mediation drives the support figure, the overnight count is worth working out carefully there rather than leaving it to be argued later.
Getting a child support order in North Carolina
The guideline figure is only half the picture. When the order actually arrives, and what it costs to argue about it, vary quite a bit from state to state, and both shape what a family lives on in the meantime.
- Residency required
- 6 months
- Waiting period
- one year
- Typical uncontested
- about 1.2 years
- Typical contested
- about 1.3 years
Support before the case is finished
You need 6 months of residency in North Carolina before you can file, and a statutory period of one year has to run before a judge can finalize the divorce. States measure that period from different starting points, some from filing, some from service on your spouse, and some from the date the two of you separated, so confirm where North Carolina's clock begins. A contested case in North Carolina runs about 1.3 years on average, against about 1.2 years when the parents agree. That gap is why temporary support matters. A judge can enter a temporary order early in the case, calculated on the same guideline, so the children are covered while the rest of the case is worked out. If money is tight now, a temporary order is usually the fastest relief available, and waiting for the final judgment can mean months without support.
What it costs to contest the number
Family law attorneys in North Carolina typically run $200 to $400 an hour, and mediation costs roughly $225a session. Worth doing the arithmetic before digging in: a handful of billable hours on each side can cost more than a full year of the amount being argued over. Where the disagreement is genuinely large, or where one parent's income is hard to pin down, representation earns its keep. Where the gap between the two positions is a few dozen dollars a month, mediation or a negotiated agreement almost always leaves both households better off. Our record carries collaborative divorce as available in all fifty states, so it says nothing specific about North Carolina; whether trained collaborative attorneys practise near you is a local question. Where it is on offer, both parents commit in writing to settle without litigation and use shared financial experts rather than competing ones.
Changing or enforcing a North Carolina order
Modifying an existing order
A child support order is not permanent, but it also does not adjust on its own. Either parent can ask the court to recalculate, and the general standard across states is a substantial and continuing change in circumstances since the last order. Job loss, a significant raise, a change in the parenting schedule, a new child support obligation for another child, and a change in the children's medical or childcare costs are the changes that most often qualify.
Two points catch parents out. The first is that a modification usually takes effect from the date the request is filed, not the date the circumstances changed, so waiting to file means absorbing the gap. The second is that the obligation continues in full until a judge signs a new order. An informal agreement between parents to pay less does not bind the court, and arrears can still accrue against the paying parent for the difference.
Enforcement
Enforcement runs through North Carolina's child support agency as well as the courts. Federal law requires every state to run a child support enforcement program with a common set of tools, which is why the remedies look broadly similar from state to state: income withholding straight from wages, interception of federal and state tax refunds, reporting to credit bureaus, suspension of driver's and professional licenses, liens against property, and contempt proceedings for willful non-payment. Income withholding is the default for new orders in most cases rather than a penalty applied after a missed payment.
North Carolina guideline authority and official worksheet
The North Carolina child support guideline in our data is:
- N.C. Gen. Stat. § 50-13.4(c1)
That authority controls, and the worksheet published under it is the document a court works from. The estimate on this page models the guideline, it does not replace the worksheet.
Where to get the official worksheet
Every state publishes a child support worksheet or an official calculator, and that document is what a judge or the state agency works from. North Carolina publishes the form below, and it is the one to fill in once your figures are settled. The estimate on this page models the same guideline so you can plan around it first.
- North Carolina Child Support Guidelines, AOC-A-162 Rev. 1/23, which carry Worksheets A, B and C and the Schedule of Basic Support Obligations
- North Carolina courts , the state judiciary site from our North Carolina source record.
- Office of Child Support Services, U.S. Administration for Children and Families, which maintains the directory of state child support agencies.
- National Conference of State Legislatures, child support guideline models by state, which publishes its own comparison of the guideline model each state uses, so you can check ours against it.
Child Support in North Carolina - Frequently Asked Questions
How is child support calculated in North Carolina?
North Carolina uses the Income Shares Model to calculate child support, and we have read the guideline that says so. Both parents' incomes are combined, and each parent's share of the total obligation is proportional to their share of the combined income. The figure North Carolina's own guideline works from is combined adjusted gross income, under the Schedule of Basic Child Support Obligations, adopted under N.C. Gen. Stat. § 50-13.4(c1).
Does North Carolina use the income shares model?
Yes. North Carolina is an income shares state, which is the model used by the large majority of states. Both parents' incomes are combined, a total support obligation is set from that combined figure and the number of children, and each parent is responsible for the share that matches their portion of the combined income. The parent the children live with most is treated as spending their share directly, so only the other parent's share becomes a payment.
How do overnights affect child support in North Carolina?
They change it, and the calculator on this page changes with them, because we have read North Carolina's own rule rather than inferring one. N.C. Gen. Stat. § 50-13.4(c1) switches the calculation onto a different route once the parenting time reaches a set threshold, and the figure steps at that boundary rather than sliding toward it. The catch worth knowing before you plan around it is that BOTH parents have to clear the line, not only the one asking for the adjustment, so a schedule giving one parent far more than half the year can put the case outside the shared route entirely. Move the overnight slider above and you will see the figure change. The parenting time section on this page sets out the threshold, the wording of the boundary and what happens either side of it.
How much is child support for 2 children in North Carolina?
It depends on the incomes involved, so there is no single figure. As a worked example, two children with the paying parent earning $5,000 gross a month, the other parent earning $3,000, and a standard 80-overnight schedule produces an estimate of $1,079 a month ($12,948 a year) under North Carolina's guideline. Change the incomes and the number moves. So does changing the overnights, because North Carolina's own parenting-time rule is read from the state's guideline and applied here. Run your own figures in the calculator on this page.
Can child support be modified in North Carolina?
Yes. Either parent can request a child support modification if there has been a substantial change in circumstances, such as a significant change in income, change in custody arrangements, or changes in the child's needs. Courts in North Carolina typically require a change of at least 15-20% in the support amount to justify modification.
Does custody arrangement affect child support in North Carolina?
Yes, twice over: it sets which parent pays, and it changes the amount. North Carolina's own rule for how it changes the amount is read from the state's guideline and applied in the calculator on this page, so the arrangement you enter moves the figure rather than leaving it standing. The parenting time section above sets out what the rule actually turns on, which is worth reading before you agree to a schedule: in a threshold state it is usually the count each parent is left with rather than the count either one is given.
Is there an income cap for child support in North Carolina?
Not a cap, and not a ceiling that the guideline reaches past either. North Carolina's Schedule of Basic Support Obligations ends at $40,000 of combined adjusted gross monthly income, $480,000 a year, and what the guidelines say above that is unusually blunt: "the supporting parent's basic child support obligation cannot be determined by using the child support schedule". There is no guideline amount for your family at that income, and rather than extrapolate one we say so. What governs instead is the first sentence of G.S. 50-13.4(c), which sets support on the reasonable needs of the child for health, education and maintenance measured against the estates, earnings, conditions and accustomed standard of living of the child and the parties. The guidelines do add that the schedule "may be of assistance to the court in determining a minimal level of child support", so the figure this page shows above the line is the top row read as a floor, and it is the state's own suggestion of one rather than ours.
How long does child support last in North Carolina?
Child support in North Carolina typically continues until the child turns 18 or graduates from high school, whichever is later. Support may continue longer if the child has a disability or if the parents agree to extend support for college expenses.

How we calculate this estimate
We apply the guideline model your state actually uses, and the models differ more than most summaries suggest. Most states follow the Income Shares Model: both parents' monthly incomes are combined, a basic support obligation is drawn from that combined figure and the number of children, and each parent covers the share that matches their portion of the combined income. Which income figure gets combined is the state's own to define and it is not the same one everywhere, so this page names it for your state where the guideline has been read and does not guess at it where it has not. Percentage of Income states apply a set rate to the paying parent's income alone, and Nevada's tiered version steps that rate down across income brackets. The Melson Formula reserves a self-support amount for each parent before dividing what is left. Some states do neither: North Dakota reads a dollar figure off a table keyed to one parent's net income, and California publishes a single algebraic formula with no schedule behind it. Which one your state is on is named on its own page rather than inferred from a list here. Credits for health insurance and childcare are applied where the state's own guideline builds them into the order, along with any income cap the state sets, and the list of what moves the number on each state's page names the levers that actually move that state's figure. Parenting time is computed in the states whose own guideline we have read and implemented, and in no others.
What the estimate assumes for North Carolina
- Income figures are gross monthly, before taxes, counting the sources your state includes.
- Parenting time moves the figure only where we have read and implemented the state's own rule. The parenting-time section further down this page says which case this state is in, and where no adjustment applies the estimate is the amount before one. We previously reduced support past 146 overnights on a coefficient of our own. 146 turned out to be a single state's statutory threshold applied to all fifty, the size of the reduction had no legal source anywhere, and the mechanisms states actually use are not variations on one rule. Among the ones we have now read: a worksheet that switches at a threshold both parents must clear, an offset applied continuously with no trigger, a threshold that does nothing below it and slides above it, a term written into the guideline formula itself so there is no unadjusted amount at all, no parenting-time term anywhere, and a formula prescribed by statute whose text we do not have. That list is what we have read rather than what exists, and it has grown with every state checked. We removed ours rather than defaulting it, and we publish each state's adjustment as that state's own rule is verified.
- North Carolina is one of the verified threshold cases, at 123 overnights under the guidelines adopted pursuant to N.C. Gen. Stat. 50-13.4(c1). The threshold has to be cleared by both parents, which is why a parent well past an even split can fall outside shared care entirely.
- Texas has no parenting-time adjustment at all, because its guideline has none. Tex. Fam. Code 154.125 runs on the obligor's net resources and the number of children, and the state's own calculator has no field for overnights. Possession time enters only as a discretionary deviation factor, Tex. Fam. Code 154.123(b)(4).
- Georgia has a mandatory parenting-time adjustment whose formula we do not have. O.C.G.A. 19-6-15(g), effective January 1 2026, requires the court to adjust the noncustodial parent's basic obligation wherever there is a court-ordered parenting time schedule, with the result entered on Child Support Schedule C. Applying arithmetic of our own in place of a prescribed formula would be worse than applying none, so the Georgia estimate is the presumptive amount before that adjustment.
- Where a state's own schedule has been transcribed, the basic obligation is read straight off it. Where it has not, the figure comes from a national approximation of the tables courts read from, and the source panel on that state's page says which of the two you are looking at. That approximation has been measured against the seven transcribed schedules keyed to the same thing it is, at 546 income and family-size combinations. It missed them by 32 to 86 percent on average, and it missed them in both directions at once: at every income from $1,500 to $6,000 of combined monthly income it came in under at least one of those schedules and over another, then above all seven from $8,000 up, reaching 69 to 240 percent above those states' own tables at $30,000. So a modeled figure at a high combined income is the least reliable number this calculator returns, and near $6,000 is where the approximation lands closest.
- Where a state sets an income ceiling, we clamp income at it. That is a fair model of a real cap and a poor one of everything else, so two states are handled differently. New York's $193,000 of combined parental income is the point above which a court may consider the additional income, not a limit on what it can order, and our figure there is the amount the guideline produces at the threshold. New Jersey's Appendix IX-F schedule ends at $3,600 of combined weekly net income, and courts are instructed in capital letters not to extrapolate past it, so we read the obligation at the schedule's last row and treat the result as the minimum basic support award rather than as a guideline amount. Appendix IX-A requires a New Jersey court to add to that minimum from the income above the ceiling. Modeling what a court adds is not something we can do honestly, because it turns on statutory factors rather than on arithmetic. Above the New Jersey line our figure is therefore a floor, and above the New York line it is not one: the addition New Jersey requires is what makes its schedule figure a minimum, and no New York instrument says an award may not come in below the amount at the threshold. Both figures read as the low end of a realistic range and only one of them is a floor a reader can count on.
- The same schedule can also stop short at the bottom. New Jersey publishes no award figure below $180 of combined weekly net income, where the court sets the amount from the paying parent's income and living expenses within a published range. Our estimate at that income is a modeled figure with nothing from the state to check it against, and it says so.
- The result is a guideline number. Judges can deviate from it when the facts justify a different amount.
Where the estimate stops
Your state's official worksheet is the controlling document, and a court order can land somewhere other than any guideline estimate. Use this to prepare, then confirm the figure with a licensed family law attorney or your state's child support agency.
