Florida Child Support Calculator
Parents' incomes & custody
Use monthly net income: gross income minus taxes, FICA, mandatory retirement and similar deductions under Fla. Stat. 61.30(3). Add-on costs are shared in proportion to income.
Example: $3,000 + $2,000 incomes, 2 children, 52/313 overnights → Parent A pays Parent B $930.60/month.
Behind the numbers
How Florida child support is calculated
Florida uses an income-shares model under Fla. Stat. 61.30. First, add both parents' monthly net incomes to get combined net income. Second, look up the basic obligation for that combined income and the number of children in the statutory schedule in 61.30(6), which runs from $800 to $10,000 of combined monthly net income; above $10,000, a percentage of the excess is added (5% for 1 child, 7.5% for 2, 9.5% for 3, 11% for 4, 12% for 5, 12.5% for 6). Third, add work-related child care and the child's health insurance costs, then split the total between the parents in proportion to income. Finally, if each parent has at least 73 overnights a year (20% time-sharing), the shared-parenting formula in 61.30(11)(b) applies: each share is multiplied by 1.5 and cross-multiplied by the other parent's overnight percentage. Between schedule points this calculator interpolates in a straight line, so it is an estimate of the schedule, not the official worksheet.
Combined net income $3,000 + $2,000 = $5,000. Schedule for $5,000 with 2 children = $1,551 basic obligation. Parent A share: 60% × $1,551 = $930.60. Parent B share: 40% × $1,551 = $620.40. Parent A has 52 overnights and Parent B has 313, so the 73-overnight shared-parenting rule does not apply, and the parent with less time pays their share: Parent A pays Parent B $931 per month, rounded.

Tips before you rely on the number
Use net income, not gross pay — the schedule is based on income after taxes and the deductions listed in 61.30(3).
Keep pay stubs and tax returns: a court will want proof of income, and income can be imputed if a parent is voluntarily unemployed.
Count child care and health insurance separately — they are added to the basic obligation and shared by income percentage.
Time-sharing matters: 73 overnights or more for each parent changes the result under the shared-parenting formula.
The guideline amount is presumed correct, but a judge can depart from it by more than 5% only with a written finding.

Frequently asked questions
Is this the exact amount a Florida court will order?
No. This is a 2026 estimate from the guideline schedule in Fla. Stat. 61.30. The official Child Support Guidelines Worksheet, the exact schedule row for your combined income, add-on costs and any deviation can change the result, and only a court sets the final amount.
What happens above $10,000 of combined monthly net income?
The schedule stops at $10,000. Above that, the $10,000 amount is used as the base and a percentage of the income over $10,000 is added: 5% for 1 child, 7.5% for 2, 9.5% for 3, 11% for 4, 12% for 5 and 12.5% for 6 children.
How does time-sharing change child support in Florida?
When each parent has at least 73 overnights a year, the shared-parenting formula applies: each parent's share is multiplied by 1.5, then cross-multiplied by the other parent's overnight percentage, and the difference is the transfer. Equal time does not automatically mean no support, because the shares are weighted by income.
Does child support end at age 18 in Florida?
Usually, yes — support generally ends at 18, or at 19 for a child still in high school who is performing in good faith and expected to graduate before turning 19.
