New Mexico Child Support Guidelines & Calculator
A state-specific overview of New Mexico child support guidelines, income model, parenting-time adjustments, and an estimate you can run with your own numbers.
Informational only—not legal advice. Laws and guidelines change. Verify the current rule with the official court resource and a licensed New Mexico family-law attorney.
What the estimate uses
For one child, this reference model uses an effective guideline rate of about 17%; for two children, about 25%. These are planning estimates, not the official worksheet amount.
Parenting-time adjustment
A shared-parenting adjustment may apply at about 128 overnights per year for the lesser-time parent. The exact credit depends on the current worksheet and the facts of the case.
Income protection and add-on expenses
The reference model includes an estimated self-support reserve of about $1,100 per month. Childcare, medical costs, insurance, and other add-ons can change the final amount.
Why the number may differ
Worksheet B (shared responsibility) applies when each parent has the children at least 35% of the year. State tables, caps, credits, and court practices change. Use the estimate as a conversation starter and confirm the current worksheet with the New Mexico court resource or a family-law attorney.
