What a Florida child support calculator usually needs to answer
50/50 custody
Whether equal timesharing still leaves one parent paying support. In Florida, it often does.
73+ overnights
Whether the schedule triggers substantial timesharing and flips the worksheet into Gross Up territory.
Gross Up impact
How dual-household costs change the base number compared with a simpler support estimate.
How Florida Child Support Is Calculated
Florida child support is calculated under Florida Statute § 61.30 using an income shares model. If you are searching for a Florida child support calculator, the key drivers are each parent's income, the number of overnights, health insurance, childcare, and whether the case crosses into substantial time-sharing territory.
The Florida wrinkle most people miss is the Gross Up method. Once each parent has at least 73 overnights a year, the calculation changes to reflect the cost of maintaining two active households for the child.

Frequently Asked Questions
How accurate is this Florida child support calculator?
Our calculator implements the exact formulas from Florida Statute § 61.30, including the Income Shares model and Gross Up method for substantial time-sharing. Results are based on current guideline tables and official calculation methods used by Florida courts.
How does Florida child support work in a 50/50 custody case?
A 50/50 schedule does not automatically eliminate child support in Florida. The court still compares both parents' incomes, applies the guideline worksheet, and then adjusts the result using the substantial time-sharing rules when each parent has enough overnights.
What is the Florida Gross Up method?
When both parents have substantial time-sharing, Florida multiplies the base support amount by 1.5 before allocating it between the parents. This is commonly called the Gross Up method, and it exists because two heavily involved households usually cost more than one.
What counts as income in Florida child support calculations?
Florida has a broad income definition including wages, self-employment income, bonuses, disability benefits, unemployment compensation, pension payments, Social Security, rental income, interest, dividends, and more. Only public assistance per F.S. § 409.2554 is specifically excluded.
Why does the 73-overnight threshold matter in Florida?
The 73-overnight threshold is the trigger for substantial time-sharing treatment. If each parent has at least 73 overnights per year, the worksheet shifts into the Gross Up framework instead of using the simpler base calculation.
How does Florida handle high-income cases?
For combined net incomes exceeding $10,000 per month, Florida uses a percentage formula for the excess amount above $10,000. Courts may also consider the child's standard of living and the specific facts of the case when the numbers get larger or more contested.
How does the calculator determine substantial time-sharing?
Substantial time-sharing exists when each parent has at least 73 overnights (20%) with the child annually. Our calculator automatically detects this threshold and switches to the Gross Up method when applicable, providing transparency about which calculation method is being used and why.
