How Florida Calculates Child Support, and Why the Formula Matters
Florida determines child support obligations using the Income Shares model, one of three approaches used across the United States.
How the three national child-support formula models differ
The Income Shares model (used by 41 states) combines both parents' incomes to estimate what the family would have spent on the children if intact, then divides that obligation in proportion to each parent's share of the combined income. The Percentage of Income model (used in states like Alaska, Mississippi, Nevada, North Dakota, Texas, and Wisconsin) takes a fixed percentage of the non-custodial parent's income based on the number of children. The Melson Formula, adopted in Delaware, Hawaii, and Montana, layers a self-support reserve on top of the Income Shares approach so neither parent's basic needs are consumed before the child's obligation is met.
This calculator applies the Florida-specific statutory tables and adjustments: parenting-time credit adjusts the obligation when the non-custodial parent has substantial overnight visitation, and healthcare insurance and work-related childcare are typically added and split proportionally. The result is an estimate of presumptive support, state courts can and do deviate upward or downward based on factors like high income, extraordinary medical expenses, or the non-custodial parent's other dependents. For a binding order, the official Florida worksheet must be filed with the court. Pair this calculator with the per-state guideline page for current multipliers, deviation factors, and review/modification thresholds.
