How District of Columbia calculates child support

District of Columbia uses the income shares model, the most common method among US states. The formula combines both parents' gross monthly income, looks up the total child-rearing obligation from District of Columbia's guideline schedule, then splits that obligation proportionally based on each parent's share of the combined income.

How the calculation works in District of Columbia

Both parents' incomes are added together to determine combined monthly income. District of Columbia's guideline tables identify the total monthly cost of raising the children at that income level. Each parent is responsible for the percentage of that total that matches their share of the combined income. The parent with less parenting time pays their share to the parent with more parenting time.

Parenting time adjustment

District of Columbia's guideline can lower the paying parent's obligation when they have substantial parenting time. Where that starts and how large the change is depend on District of Columbia's own rule, which the calculator applies when you enter parenting time.

Add-ons

Healthcare premiums for the children and work-related childcare costs are typically added to the base obligation and split proportionally by income in District of Columbia.
