Child Support Calculator
A ballpark estimate based on both parents' income, number of children, and how time is split. For planning conversations, not court filings.
This is a simplified, illustrative estimate, not legal advice. Real child support formulas (income shares, percentage of income, and others) vary by state and county, and courts can deviate from the standard formula. Use this to get a rough sense of the numbers before a conversation, not as a figure to rely on in a filing. Confirm actual numbers with your state's official guidelines or a family law attorney.
More time with Parent B reduces their estimated payment, since they're covering more day-to-day costs directly.
