Estimate monthly child support obligations using the Colorado Income Shares Model.

What is the Colorado Child Support Calculator?

The Colorado Child Support Calculator is a specialized tool designed to help parents, legal professionals, and mediators estimate the monthly financial obligation one parent may owe to another following a divorce or legal separation. In Colorado, child support is determined using the "Income Shares Model," which is based on the concept that a child should receive the same proportion of parental income that they would have received if the parents were still living together.

Who should use this tool? Any parent residing in Colorado or dealing with a Colorado court order regarding child custody. It is essential for those planning their financial future post-separation. A common misconception is that child support is a "punishment" or a flat percentage of income; in reality, the Colorado Child Support Calculator accounts for combined income, the number of children, and the specific parenting time (overnights) each parent has.

Colorado Child Support Calculator Formula and Mathematical Explanation

The mathematical foundation of the Colorado Child Support Calculator involves several steps to ensure an equitable distribution of costs. The state provides a "Schedule of Basic Child Support Obligations" which we approximate in our logic.

Step-by-Step Derivation:

1. Calculate Combined Gross Income: Sum the monthly gross income of both parents.
2. Determine Basic Obligation: Use the state schedule to find the base amount needed for the number of children at that income level.
3. Calculate Proportional Share: Divide each parent's income by the total combined income.
4. Adjust for Parenting Time: If a parent has more than 92 overnights (Shared Care), a 1.5x multiplier is applied to the basic obligation to account for duplicated costs in two households.
5. Add Extraordinary Expenses: Health insurance, childcare, and medical costs are added to the basic obligation and split proportionally.

Variable	Meaning	Unit	Typical Range
Gross Income	Total monthly earnings before taxes	USD ($)	$1,500 – $30,000+
Overnights	Nights child spends with a parent	Days/Year	0 – 365
Basic Obligation	Base cost of raising a child	USD ($)	Varies by Schedule
Shared Care Threshold	Minimum nights for Worksheet B	Days	93+ Overnights

Practical Examples (Real-World Use Cases)

Example 1: Sole Custody (Worksheet A)

Parent A earns $6,000/month, Parent B earns $4,000/month. They have 2 children. Parent B has the children for 80 overnights (less than 93). The Colorado Child Support Calculator would determine the total obligation based on $10,000 combined income. Since Parent A has the majority of time, Parent B would pay their proportional share (40%) of the basic obligation to Parent A.

Example 2: Shared Parenting (Worksheet B)

Parent A earns $5,000, Parent B earns $5,000. They have 1 child and split time exactly 182.5 overnights each. Even though incomes are equal, if one parent pays for health insurance ($200), the Colorado Child Support Calculator will show a small transfer payment to balance the shared expenses and the 1.5x shared care multiplier.

How to Use This Colorado Child Support Calculator

Follow these steps to get an accurate estimate:

• Step 1: Enter Parent A's gross monthly income. Include wages, bonuses, and commissions.
• Step 2: Enter Parent B's gross monthly income.
• Step 3: Select the number of children involved in the case.
• Step 4: Input the number of overnights for Parent A. The tool will automatically calculate Parent B's overnights.
• Step 5: Add monthly costs for health insurance and work-related childcare.
• Step 6: Review the "Estimated Monthly Support" result and the breakdown table.

Key Factors That Affect Colorado Child Support Calculator Results

• Gross Income: This includes almost all sources of income, including social security, unemployment, and investment dividends.
• Number of Children: The obligation does not double for two children; it increases at a decreasing marginal rate.
• Overnight Threshold: Crossing the 92-overnight mark significantly changes the calculation from Worksheet A to Worksheet B.
• Health Insurance Premiums: Only the portion of the premium paid for the children is included in the Colorado Child Support Calculator.
• Childcare Costs: Necessary work-related childcare is a major factor in the final monthly amount.
• Other Support Obligations: If a parent is already paying support for children from a different relationship, this can often be deducted from their gross income.
