Add-ons (monthly)

Child health insurance premium Monthly — your share

What this is: The extra amount you pay each month to add your child to your health insurance plan — not your total premium, just the child's portion. Check your pay stub or call HR. If you don't know, leave it at 0.

Work-related childcare costs Monthly total

What this is: Daycare, after-school care, or a babysitter you pay so you can go to work — not general babysitting. This is the monthly total for both parents combined. If the child isn't in paid childcare right now, leave it at 0.

Select your state, enter both parents' incomes and overnights, then tap Estimate to see your plain English child support estimate.

Add-ons

Additional costs split proportionally

Health insurance and childcare add-ons are divided proportionally based on each parent's share of combined income in most Income Shares states.

Support Timeline

When does support end per child?

Support typically ends when each child turns 18 or graduates high school. Exact end date depends on your state and court order — always verify.

Estimates only. Child support calculations vary significantly by state, county, and individual circumstances. This estimator uses approximations of each state's formula and does not account for all deductions, adjustments, or deviations a court may apply. Actual orders are set by a judge or hearing officer. Always use your state's official calculator and consult a licensed family law attorney for advice specific to your situation.
