How New Mexico Calculates Child Support

New Mexico calculates child support using the Income Shares Model as defined in NMSA §40-4-11.1. Both parents' gross incomes are combined to determine the total support obligation from the state schedule. Each parent's share is then allocated proportionally based on their percentage of the combined income.

Health insurance premiums for the child, work-related childcare costs, and extraordinary medical expenses are added to the base obligation. These additional expenses are shared proportionally between the parents. New Mexico also maintains a self-support reserve of $1,038 per month (2024) to ensure the obligor retains enough for their own basic needs.

Courts may deviate from the guideline amount with specific written findings explaining why the guideline amount is unjust or inappropriate under the circumstances. Shared custody adjustments are also available when both parents have significant parenting time.
