The schedule now runs from $50 to $40,000 of combined monthly adjusted gross income in $50 increments, with interpolation between rows, and the presumptive minimum order is $10 per month.

The parent who will pay support (usually the one with less parenting time). Monthly gross income after the state's own adjustments (for example, support paid for other children).
The parent who receives support. Both incomes are added to find the schedule amount.
The law behind this calculator: Colorado schedule of basic child support obligations (income shares, combined adjusted gross income) — C.R.S. § 14-10-115(7)(b) Schedule of Basic Child Support Obligations, as amended by HB25-1159 (eff. Mar. 1, 2026).

How Colorado calculates it

  • Add both parents’ monthly adjusted gross incomes to get the combined income.
  • Find the basic child‑support obligation in Colorado’s schedule for that combined income and the number of children; the schedule covers $50‑$40,000 in $50 steps and amounts between rows are interpolated (or extrapolated) as the statute directs.
  • Multiply the schedule amount by the paying parent’s share of the combined income (paying parent’s income ÷ combined income).
  • If the combined income exceeds $40,000, the statute adds 0% of the excess for each child, so the top‑row figure remains the cap.
  • The $10 presumptive minimum applies, and child‑care, health‑insurance and parenting‑time adjustments are added separately and are not part of the basic figure.

Worked example

In the example, the paying parent earns $4,000 per month adjusted gross, the other parent $2,500, for a combined $6,500. The schedule row for $6,500 with two children gives a basic obligation of $1,660. The paying parent’s share of the combined income is 61.5%, so the calculated payment is 61.5% × $1,660 = $1,022 per month before any child‑care, health‑insurance, or parenting‑time adjustments.

Frequently asked questions

How does Colorado determine the paying parent’s share of child support?

Colorado uses the income‑share model: the paying parent’s share equals their adjusted gross income divided by the combined adjusted gross income of both parents, then applied to the schedule amount.

What is the minimum child‑support order in Colorado?

The presumptive minimum order is $10 per month. Low‑income rules (e.g., $650 threshold) exist but are not modeled in this calculator.

Does Colorado add extra percentages for income over $40,000?

No. For combined incomes above $40,000 the statute adds 0% of the excess for each child, so the top‑row figure is the maximum basic amount.

How are child‑care and health‑insurance costs handled?

Those costs are added to the basic obligation and split according to the income‑share percentages; they are not included in the basic schedule figure.

What changed in Colorado’s child‑support schedule on March 1 2026?

HB25‑1159 updated the schedule to run from $50 to $40,000 in $50 increments, requires interpolation between rows, and applies the same 0% excess rule for incomes above $40,000.

Is the calculation different in Denver, Colorado Springs or Aurora?

No. C.R.S. § 14-10-115(7)(b) Schedule of Basic Child Support Obligations, as amended by HB25-1159 (eff. Mar. 1, 2026) sets one statewide guideline, so a case in Denver, Colorado Springs, Aurora uses the same percentages as anywhere else in Colorado. Judges everywhere in the state may deviate only with written findings.
