Child Support Calculator in New Mexico: What You Should Know
New Mexico uses the Income Shares Model under Section 40-4-11.1, combining both parents' gross monthly incomes to find the basic obligation. The state provides two worksheets: one for sole physical custody and one for shared custody where each parent has the children at least 35 percent of the year, and the shared worksheet generally produces a lower payment. Each parent's share is proportional to their income, with childcare and medical costs added on. There is no statutory income cap on the calculation.
Key point: New Mexico uses the Income Shares Model with a separate shared-custody worksheet that applies once each parent has the children at least 35 percent of the year.

Child Support in New Mexico - Frequently Asked Questions
How is child support calculated in New Mexico?
New Mexico uses the Income Shares Model to calculate child support. Both parents' gross incomes are combined, and each parent's share of the total obligation is proportional to their share of the combined income.
Can child support be modified in New Mexico?
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 New Mexico typically require a change of at least 15-20% in the support amount to justify modification.
Does custody arrangement affect child support in New Mexico?
Yes. Parenting time is a significant factor in child support calculations. When a parent has the children for a substantial portion of time (typically 40% or more overnights per year), child support is adjusted to reflect the additional direct costs that parent bears.
Is there an income cap for child support in New Mexico?
New Mexico does not set a specific income cap in its child support formula. However, courts have discretion to deviate from the guideline amount in cases with very high incomes.
How long does child support last in New Mexico?
Child support in New Mexico 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.
