Florida uses an income shares model under §61.30 that combines both parents’ net monthly incomes to determine a total basic support obligation from a published schedule. Each parent's share is proportional to their percentage of combined income. Substantial timesharing (73+ overnights) triggers a gross-up adjustment.

Florida calculates child support using the Income shares model established under §61.30. This is a statutory formula that leaves limited room for judicial discretion on the base calculation amount, ensuring consistency and predictability for families across the state.
Approximate percentages of combined net income: 1 child ~18%, 2 ~27%, 3 ~34%, 4 ~39%, 5 ~43%, 6+ ~46%. Each parent pays pro rata share based on income percentage. Above $10,000 combined, excess percentages apply.
The calculation begins with determining each parent's net disposable income, which includes virtually all sources of income minus taxes, mandatory payroll deductions, and certain hardship deductions. The court then applies the statutory formula using the time each parent has primary physical responsibility for the children and the applicable income allocation brackets.
Beyond the base formula amount, Floridarequires additional contributions for mandatory add-on expenses. These typically include childcare costs necessary for the custodial parent's employment or education, uninsured healthcare expenses for the children, and in some cases, educational and travel costs. These add-ons are split between parents in proportion to their respective incomes.

Basic Support Schedule (§61.30(6)) covers combined net monthly income up to $10,000.
Above $10,000 combined, excess percentages apply: 1 child = 5%, 2 = 7.5%, 3 = 9.5%, 4 = 11%, 5 = 12%, 6+ = 12.5% of excess.
Timesharing adjustment: 73+ overnights per year triggers gross-up calculation.
Mandatory minimum: $50/month per child even if the calculation yields less (§61.30(6)(a)).
Add-ons split proportionally: health/dental/vision insurance, work-related childcare, uncovered medical >$250/year/child.
