Colorado Child Support Calculator
Estimate your child support obligations in Colorado using the income shares model. Understand how support is calculated, what factors matter, and what to expect. Updated for 2026.
Colorado uses the Income Shares Model under C.R.S. § 14-10-115. Both parents' adjusted gross incomes are combined to determine the Basic Child Support Obligation from a statutory schedule. Each parent's proportionate share is based on their percentage of combined income. Adjustments are made for health insurance, childcare costs, extraordinary medical expenses, and shared parenting time (multiplied by 1.50 for shared physical care). The guidelines apply to combined adjusted gross income up to statutory limits.
