Florida Child Support Calculator
Florida's income-shares guideline combines both parents' net monthly incomes, reads the basic obligation from the §61.30 statutory schedule, and splits it in proportion to income — with a mandatory 1.5× gross-up formula whenever either parent has the children at least 20% of overnights. This calculator implements the current statute, including the schedule's full $800–$10,000 range and the above-$10,000 extension percentages.

This is a guideline estimate under Fla. Stat. §61.30 for informational purposes only — it is not legal advice and not a substitute for the official worksheet or a family-law attorney. Courts can deviate from guideline amounts based on statutory factors, and inputs like income determination or imputed income are ultimately decided by the court.

Net income under §61.30
Each parent's gross income (wages, self-employment, bonuses, disability, rental income and more) minus federal income tax, FICA, mandatory union dues and retirement, health insurance premiums (excluding the child's portion), and court-ordered support actually paid for other children. Both parents' nets are combined for the schedule lookup.
The time-sharing gross-up
Whenever a parenting plan gives either parent at least 20% of overnights, §61.30(11)(b) requires a different computation: multiply the obligation by 1.5, take each parent's pro-rata share, multiply each share by the other parent's percentage of overnights, and offset. More overnights for the paying parent means a smaller transfer — at high time shares the direction can even flip.
Add-ons and the 5% band
Work-related childcare and the child's health insurance cost are added to the basic obligation and allocated by income share, with credit to whichever parent actually pays. Courts may adjust the final figure by ±5% without written findings — treat results as the center of that band.
Frequently asked questions
Is Florida child support based on gross or net income?
Net income, defined by §61.30(2)–(3): gross income minus federal income tax, FICA or self-employment tax, mandatory union dues, mandatory retirement contributions, health insurance premiums (excluding coverage for the child), and court-ordered support for other children actually paid. Florida has no state income tax, so nothing is deducted for it.
How does 50/50 custody change Florida child support?
Any split where each parent has at least 20% of overnights triggers the §61.30(11)(b) formula: the schedule obligation is multiplied by 1.5, each parent's pro-rata share is weighted by the other parent's overnight percentage, and the difference is the transfer. At exactly 50/50, the transfer is driven purely by the income gap — equal incomes produce $0, and a 60/40 income split still produces a meaningful payment from the higher earner.
What if combined income is above the schedule's $10,000 maximum?
The obligation is the schedule amount at $10,000 plus a percentage of the excess: 5% for one child, 7.5% for two, 9.5% for three, 11% for four, 12% for five, and 12.5% for six. Example: $12,000 combined net with 3 children = $2,795 + 9.5% × $2,000 = $2,985/month before the pro-rata split.
What about very low incomes?
If the paying parent's net income is below $800/month, the obligation is the lesser of the schedule-based share or 90% of the amount by which their income exceeds the federal poverty guideline (about $1,330/month for one person in 2026) — which can reduce the presumptive amount to zero, though courts retain discretion to order a nominal amount.
Can a Florida judge order a different amount than the guideline?
Yes, within limits: ±5% from the guideline amount requires only that the court consider the relevant factors; deviating more than 5% requires a written finding explaining why the guideline would be unjust or inappropriate. Courts can also impute income to a parent who is voluntarily unemployed or underemployed, based on work history and local earning levels.
How do childcare and health insurance affect the total?
Employment-related childcare costs and the child's health insurance premium are added on top of the basic obligation and split by income share (§61.30(7)–(8)). Whoever actually pays the expense gets a credit for the other parent's share. Unreimbursed medical expenses are typically allocated the same way in the order itself.
