District of Columbia child support guidelines
Washington, D.C. uses a hybrid child-support guideline — it starts from an income-based share and then adjusts for both parents’ circumstances. This page explains the approach and links the official DC calculator; it doesn’t compute your figure.
A blended approach
D.C.‘s guideline (D.C. Code § 16-916.01) doesn’t fit neatly into a single model. It begins by looking at a share of the paying parent’s income, then adjusts using both parents’ incomes and the children’s needs — so the outcome reflects the combined situation rather than one parent’s income in isolation. The current framework was substantially revised by the Child Support Guideline Revision Amendment Act of 2016. Inputs include both parents’ incomes, the number of children, and health-insurance and childcare costs.
The self-support reserve, age 21, and modification
D.C. protects low-income parents with a self-support reserve of about $1,650/month: if the full guideline amount would drop a parent below it, the court may set a minimum order of about $75/month instead. The District is also one of the few places where the age of majority is 21, so support generally runs until the child turns 21 (ending earlier on emancipation, marriage, or military service). A recalculation differing by 15% or more from the current order is presumed to meet the changed-circumstances test for modification.
Use the official calculator
Because the guideline layers several factors, the DC Office of the Attorney General publishes an official Child Support Guideline Calculator (linked above) that runs the current rules. Use it for an actual estimate; this page only explains the model.
For a real case
The guideline result is a starting point, and a D.C. court can adjust it in the child’s interest. For advice on your circumstances, consult a family-law attorney licensed in the District of Columbia.

This page is general information, not legal advice. Child support in District of Columbia is set by District of Columbia’s official guidelines, and the amount in any real case is determined by the court or the state child-support agency using the official worksheet — not by this page. Guideline figures, schedules, and adjustments change over time and depend on facts specific to your situation (each parent’s income, parenting time, health-insurance and childcare costs, and other factors a court may consider). Use the official District of Columbia calculator for an actual estimate, and consult a licensed family-law attorney in District of Columbia for advice about your circumstances.

Frequently asked questions
- How is child support calculated in Washington, D.C.?
- D.C. uses a hybrid guideline (D.C. Code § 16-916.01). It begins by looking at a share of the paying parent's income, then adjusts using both parents' incomes and the children's needs, so the result reflects the combined circumstances rather than one parent's income alone. The DC Office of the Attorney General publishes an official Child Support Guideline Calculator.
- What makes the D.C. model a hybrid?
- It blends elements of the percentage-of-income and income-shares approaches: it starts from an income-based share but then factors in the other parent's income and the children's needs. D.C.'s current guideline framework was substantially revised by the Child Support Guideline Revision Amendment Act of 2016 and is applied through the official calculator.
- Is there a self-support reserve or minimum order?
- Yes. D.C. protects low-income parents with a self-support reserve of about $1,650 a month; if paying the full guideline amount would drop the parent below it, the court may set a minimum order of about $75 a month instead. The reserve keeps a paying parent above a basic standard of living.
- How long does D.C. child support last, and when can it change?
- The District is one of the few places where the age of majority is 21, so support generally continues until the child turns 21 (ending earlier on emancipation, marriage, or military service). A recalculation that differs by 15% or more from the current order is presumed to meet the changed-circumstances test for modification.
- Where do I get an official estimate?
- Use the DC Office of the Attorney General Child Support Guideline Calculator linked on this page. This page explains the model but does not compute an amount, and it is not legal advice.
