Florida family law tool

Florida Child Support Calculator

Enter each parent's gross income and tax information. The calculator estimates federal income tax, Social Security, Medicare, allowable deductions, monthly net income, and guideline support.

This calculator provides an estimate and is still being tested for accuracy. Talk to an attorney before relying on any calculator. It is common for attorneys to disagree about the proper calculation. This tool is not legal advice and does not predict what a judge will order. Income classification, allowable deductions, low-income rules, Social Security credits, deviations, and other facts may change the result.

It applies the guideline schedule in Florida Statutes § 61.30, each parent's income percentage, qualifying child-care and health-related expenses, credits for the parent who prepays those expenses, and the substantial time-sharing formula when each parent has at least 20% of the overnights.
