One-child base rate at New Mexico's median income
18% of $51,945, the Census ACS 2022 median household income for New Mexico, divided across twelve months, 18% below the median state. An index for comparing states, not a case estimate: guidelines apply to the obligor's income, or to combined parental income under the Income Shares model, and a court sets the actual order. How this is derived.

How New Mexico Calculates Child Support
New Mexico uses the Income Shares model. Both parents' incomes are combined, the total obligation is looked up from a schedule, then split proportionally based on each parent's income share. Its one-child base rate is in line with the national middle range. Pair the schedule math with New Mexico's thinner-than-most order-establishment share when reading enforcement.
