New Mexico guideline inputs

Worksheet B starts when the lesser-time parent has 128 days.

Estimated monthly child support: $989.38

The paying parent pays this amount to the receiving parent each month.

Assumptions

  • Inputs are monthly gross income after only the deductions allowed by the New Mexico worksheet.
  • The official 2024 schedule lookup uses the lower threshold row, matching the Judicial Branch calculator.
  • The payer has no more than 127 days, so Worksheet A applies.
  • The ordinary combined-income allocation applies.
  • Combined income is within the published schedule.
  • The published child-count column applies.
  • Health insurance, work-related childcare, additional expenses, prior support, and deviations are excluded.

The official calculator selects the worksheet by days

Worksheet A applies through 127 days for the lesser-time parent. At 128 days, Worksheet B multiplies the basic obligation by 1.5, credits each parent’s time, and offsets.

Low-income Worksheet A cases use schedule cells flagged for the self-support reserve.
