How to Use the Colorado Child Support Calculator
This calculator estimates monthly child support based on Colorado guidelines. Follow these steps:
- Enter Monthly Gross Incomes – Input the mother’s and father’s monthly gross income (before taxes) in dollars. Use numbers only (e.g., 4500.00).
- Enter Overnights Per Year – Provide the number of overnights each parent has with the child annually (0–365). The total should not exceed 365.
- Add Additional Costs (Optional) – Fill in monthly amounts for health insurance premiums, child care costs, and other extraordinary expenses if applicable. Leave blank if none.
- Check Low Income Adjustment – If the combined monthly income is under $15,000, check this box to apply a simplified 20% rate instead of the tiered formula.
- Click "Calculate Support" – The result shows the estimated monthly support amount, the paying parent, and a detailed formula breakdown.
Note: All monetary values must be in US dollars. Overnights must be whole numbers between 0 and 365. The calculator uses Colorado’s income shares model with a basic obligation of 20% of combined income (with a tiered adjustment for incomes over $10,000).

Frequently Asked Questions
Colorado uses the Income Shares Model. The combined gross income of both parents is used to determine a basic child support obligation, which is then prorated based on each parent's income share and adjusted for parenting time and additional expenses.
The calculator includes monthly health insurance premiums, child care costs, and other extraordinary expenses (e.g., medical, educational). These are prorated between parents.
If the combined monthly gross income is less than $15,000, the calculator applies a simplified percentage (20% of combined income) to determine the basic obligation, which may result in lower payments.
