Nevada Child Support Calculator

How Nevada calculates child support

Our record puts Nevada on the Tiered Percentage of Income Model, though nobody here has read Nevada's own guideline to check it, which means percentages step down across income brackets, so each slice of the paying parent's income is charged at its own rate. Here is what that looks like in practice.

The tiered model applies a percentage to the paying parent's income the way federal tax brackets work: each slice of income is charged at its own rate, and the rates step down as income rises. Income inside the first bracket is charged at the highest rate, the next bracket at a lower one, and everything above the second threshold at the lowest rate of all. The obligation therefore keeps growing with income, but at a slowing pace.

That structure is a deliberate answer to a problem flat-percentage states run into. A single rate applied to a very high income produces a number far beyond what raising a child costs, while the same rate applied to a low income can leave the paying parent unable to cover their own housing. Stepping the rate down across brackets keeps high-income orders closer to actual child-rearing costs without cutting the rate for parents earning less.

Rates rise with each additional child, and the same credits available under a flat percentage model apply here: health insurance for the children, prior support orders, and parenting time.

Rates rise with each additional child and fall as income moves into the higher brackets, so the obligation keeps climbing with income but never at a flat rate.

What moves the number in Nevada

• The paying parent's income, charged bracket by bracket
• Number of children, which sets the rate in every bracket
• Parenting time, in most states, under a rule we have not yet verified for this one
• Health insurance paid for the children
• Support already ordered for children from another relationship

Income limits and judicial discretion

We hold no income ceiling for Nevada, so the estimate on this page keeps computing as income rises rather than stopping at a row. What Nevada's own guideline does at the top of its schedule is a question this site has not answered for this state, so read a figure at a high income as our model rather than as the state's own. Courts hold authority to depart from a guideline figure when it produces an amount that does not match what the children actually need. Nevada gives judges a moderate amount of room on custody and parenting time, so the final order moves with the facts of the case as well as with the arithmetic. The figure above is our approximation of the guideline rather than the guideline itself, which is a second reason to read it as a starting point.

Nevada child support examples

These three examples run through the same Nevada 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 each figure is the amount before any parenting-time adjustment, which is explained in full below.

Comparing the first two examples shows what a second child is worth in Nevada: the order moves from $800 to $1,100a 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 Nevada

Most states do reduce support when the paying parent has the children a substantial share of the year. What differs between them is not just where the line sits. It is whether there is a line at all, and whether crossing it switches the worksheet, nudges the arithmetic, or does nothing. We apply a state's parenting-time adjustment only once we have verified that state's own rule and built the mechanism behind it, and Nevada is not there yet. The figure the calculator returns above is therefore the amount before any parenting-time adjustment. It is a real number and the right starting point, but it is an intermediate one, and changing the overnight count will not move it.

Four mechanisms are in use across the country, and they are not variations on one idea. The first is a cliff. Support is worked out one way below a set number of overnights and a different way at or above it, so the figure steps rather than slides. North Carolina is the clearest example and the first one our calculator computes in full, from the state's own published schedule. Its guidelines, adopted under N.C. Gen. Stat. § 50-13.4(c1), send a case to Worksheet B at 123 overnights a year, roughly 34 percent of the calendar. At 122 nights the standard worksheet applies. At 123 a different one does, and the same family can come out several hundred dollars apart on either side of that single night.

Where the line sits is not a national figure, and that is worth seeing rather than being told. Illinois runs the same kind of cliff and puts it 23 nights further along: under 750 ILCS 5/505(a)(3.8) the shared care route applies where each parent exercises 146 or more overnights a year, and the basic obligation is multiplied by 1.5. We compute Illinois too. So the same family, with the same schedule, gets the adjustment in North Carolina and misses it in Illinois anywhere between 123 and 145 nights. The exact wording matters as much as the number: both of those thresholds are inclusive, so a parent sitting exactly on one qualifies, while other states word the same rule as "more than", which excludes them.

The part of a cliff rule that catches parents out is that both of them have to clear the threshold, not only the one asking for the adjustment. Work that through and the result is genuinely counter-intuitive. A parent with 250 overnights leaves the other parent 115, which sits below a 123-night bar, so the case is not shared custody under the rule at all and the shared worksheet never comes out. 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 nights, check what the schedule leaves the other parent, not only what it gives you.

The second mechanism has no line in it. Some states apply a parenting-time offset across the whole range, from the first overnight that can be determined, so every additional night moves the number a little and there is no threshold to reach. Michigan is the verified example and the second state our calculator computes in full. Under 2025 Michigan Child Support Formula Manual § 3.03 the offset applies to every support determination, so a Michigan parent with five overnights a year gets one. Guides that report a single trigger figure for a state like this are usually pointing at one of two things that are not triggers: the place where the curve steepens, which is a property of the arithmetic, or a rule about something else entirely. The 21 overnights often quoted for Michigan are the second kind. That figure governs when a change in parenting time is enough to ask a court to modify an existing order, and it has nothing to do with how the offset is worked out.

The third is no adjustment at all. Texas is the plain case: Tex. Fam. Code § 154.125 runs on the paying parent's net resources and the number of children, and the state's own official calculator has no field for overnights. Possession time reaches a Texas order only as one of the factors a court may weigh in deciding whether to depart from the guideline figure, under Tex. Fam. Code § 154.123(b)(4), and a departure can move the order in either direction.

The fourth is a formula the legislature wrote out. Georgia's parenting time adjustment became mandatory on January 1, 2026 under O.C.G.A. § 19-6-15(g), which directs the court to apply a set calculation to the noncustodial parent's basic obligation wherever a court-ordered parenting time schedule exists. That is a required step inside the presumptive calculation, not an argument made after the guideline figure is settled.

Those four produce very different answers for the same family, which is why we are not applying a general rule to Nevada in the meantime. We used to. The threshold we applied was 146 nights, which is Illinois's statutory number generalised to all fifty, the size of the reduction had no legal source anywhere, and neither survived being checked, so both are gone rather than defaulted. What replaces them is each state's own rule, one state at a time, and that work has started. North Carolina's page calculates from North Carolina's published schedule and applies North Carolina's own threshold. Michigan's computes Michigan's own equations and applies an offset with no threshold at all. Illinois's reads a banded schedule keyed to net income and applies its own 146-night cliff. Those three were done in that order on purpose: the second is the opposite mechanism to the first, and the third shares a mechanism with the first while differing from it on every number in it. We will publish Nevada's parenting-time adjustment here once we have read it out of Nevada's own guidelines to the same standard. Until then the figure above is the amount before that adjustment, and Nevada's official child support worksheet, linked below, is where the adjusted number comes from.

Where Nevada starts on parenting time

Nevada does not presume equal parenting time. That is our own record rather than Nevada'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 should find out what Nevada's own guidelines do with the count they end up with before agreeing to it.

Getting a child support order in Nevada

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

42 days

Waiting period

None

Typical uncontested

2 months

Typical contested

10 months

Support before the case is finished

You need 42 days of residency in Nevada before you can file, and no statutory waiting period applies before a judge can finalize the divorce. A contested case in Nevada runs 10 months on average, against 2 months 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 Nevada typically run $250 to $450 an hour, and mediation costs roughly $250a 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 Nevada; 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 Nevada 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 Nevada'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.

Nevada guideline authority and official worksheet

Nevada carries its child support guideline across more than one instrument, and all of them are in our data:

• Nev. Admin. Code § 425.140
• Nev. Rev. Stat. § 425.620

Those authorities control, and the worksheet published under them is the document a court works from. The estimate on this page models the guideline, it does not replace the worksheet.

Nev. Admin. Code § 425.140 is issued under Nev. Rev. Stat. § 425.620 and took effect February 1, 2020. The percentages have not moved since, but the bottom of the schedule does move: NAC 425.145 requires the Administrative Office of the Courts to publish an updated low-income schedule by March 31 each year. Nevada is a static base rule with an annually moving floor, so a low-income figure quoted from an older copy will be out of date even though the brackets are not.

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. We do not yet have a verified direct link to Nevada's worksheet, so the starting points below are the state's own court site and the federal directory of state child support agencies rather than a deep link we cannot vouch for.

• Nevada courts , the state judiciary site from our Nevada 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.

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 Nevada

• 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.
