When either parent exercises 73+ overnights per year, Florida uses the gross-up method where the basic support obligation is multiplied by 1.5 before calculating overnight shares.

How Florida Child Support Is Calculated

Florida child support determinations follow the Income Shares Model codified in Florida Statute § 61.30. This model operates on the principle that the child should receive the same proportion of parental income that they would have received if the parents lived together in a single household.

2. Final Monthly Support Obligation Formula
Monthly Transfer=(Basic Schedule Obligation + Childcare + Healthcare) × Income %−Substantial Time Credit
Step-by-Step Calculation Breakdown ($5,000 vs $3,000 Net Incomes, 2 Children)
Step 1: Determine Combined Net Income and Pro-Rata Shares
• Parent 1 Net Income: $5,000 / month (62.5% share)
• Parent 2 Net Income: $3,000 / month (37.5% share)
• Combined Net Monthly Income: $8,000 / month
Step 2: Lookup Statutory Guideline & Add-On Pool
• Florida statutory schedule obligation (2 children on $8,000): $1,760
• Add-Ons: Healthcare ($200) + Childcare ($350) = $550
• Total Combined Child Support Need: $2,310 / month
Step 3: Apportion Pro-Rata Obligation & Apply Time-Sharing Credit
• Parent 1 Gross Share (62.5% of $2,310): $1,444
• Substantial Time-Sharing Credit (110 overnights / ~30%): -$99
Estimated Net Monthly Transfer: $1,345 / month

Frequently Asked Questions

How does Florida calculate child support?
Florida uses the Income Shares Model codified in Florida Statute § 61.30. It calculates the total basic child support obligation by combining both parents' net monthly incomes, applying the statutory guideline schedule, and apportioning responsibility according to each parent's percentage of total net income.
How does substantial time-sharing (overnights) affect Florida child support?
Under Florida's 'Gross-Up Method', if the non-custodial parent exercises 73 or more overnights per year (20%+ time-sharing), the court applies a substantial time-sharing adjustment formula that multiplies the basic obligation by 1.5 and allocates costs based on overnights.
What deductions are allowed from gross income in Florida?
Florida permits deductions for federal, state, and local income taxes, FICA and Medicare contributions, mandatory union dues, mandatory retirement payments, health insurance premiums (excluding the child's portion), and court-ordered support for other children.
How are healthcare and childcare expenses divided in Florida?
Work-related childcare costs and health/dental insurance premiums for the children are added to the basic support obligation and divided pro-rata according to each parent's share of combined net income.
When can a Florida child support order be modified?
A modification requires proving a substantial, material, involuntary, and permanent change in financial circumstances, resulting in at least a 15% or $50 change (whichever is greater) in the support calculation.
