How Florida Child Support Is Calculated
Florida uses the "Income Shares Model" under F.S. 61.30, which considers both parents' incomes to determine child support.
Calculate Net Income
Start with gross income, then subtract allowable deductions (taxes, FICA, health insurance for yourself, mandatory retirement).
Combine Incomes
Add both parents' net incomes together to get the combined monthly net income.
Find Guideline Amount
Look up the combined income in Florida's guideline table based on number of children.
Apply Adjustments
Add health insurance and childcare costs, then adjust for time-sharing if applicable (20%+ overnights).
Key Factors in Florida Child Support (F.S. 61.30)
Both Parents' Income
Under F.S. 61.30(2)(a), income includes salary, wages, bonuses, self-employment, rental income, investments, and benefits.
Time-Sharing Adjustment
Per F.S. 61.30(11)(b), if the paying parent has 20%+ overnights (73+ nights/year), support is adjusted using a special formula.
Additional Expenses
Health insurance for children and work-related childcare costs are added to the base support and shared proportionally.
Allowable Deductions (F.S. 61.30(3))
These are subtracted from gross income to calculate net income:
- Federal and state income taxes
- FICA (Social Security and Medicare)
- Mandatory retirement contributions
- Health insurance premiums (for yourself only)
- Union dues
- Court-ordered support for other children
Frequently Asked Questions
How accurate is this Florida child support calculator?
This calculator uses the official Florida Child Support Guidelines from F.S. 61.30. However, actual court-ordered support may vary based on deviations (up to 5% without justification), special circumstances, and judicial discretion. For an official calculation, you'll need to complete Florida Family Law Form 12.902(e).
What if my income is above the guideline table maximum?
The Florida guidelines cover combined net income up to $15,000/month. For higher incomes, courts have discretion to determine support based on the children's needs and the parents' ability to pay. The percentage of income approach is commonly used.
Can the court deviate from the guideline amount?
Yes. Under F.S. 61.30(1)(a), courts can deviate up to 5% from the guidelines without written justification. Larger deviations require specific findings, such as extraordinary medical expenses, special needs, or other relevant factors.
How does 50/50 custody affect child support?
Even with equal time-sharing (50/50), the higher-earning parent typically pays some child support. The amount is reduced due to the time-sharing credit, but the income difference usually results in some payment obligation.
When can I modify child support in Florida?
Under F.S. 61.14, you can petition to modify if there's a substantial change in circumstances—typically a 15%+ income change or $50+ change in monthly support, significant time-sharing change, or substantial change in the child's needs.
