How Child Support is Calculated in Florida
Florida uses an Income Shares model under Florida Statute §61.30. The state publishes a Basic Child Support Obligation table based on combined monthly net income. Each parent pays their proportional share, with adjustments for overnight timesharing of 20% or more.

Frequently Asked Questions — Florida Child Support
What is Florida's substantial timesharing threshold?
When the non-residential parent has at least 20% of overnights (about 73 nights/year), Florida applies the gross-up multiplier that reduces the support amount.
Can Florida child support exceed the guideline?
Courts can deviate up to 5% from the guideline without explanation. Larger deviations require written findings about the child's specific needs.
Does Florida count overtime and bonuses?
Yes. Florida includes nearly all forms of income — wages, bonuses, commissions, business income, rental income, and disability benefits.
When does Florida child support end?
Generally at age 18, or up to 19 if the child is still in high school and reasonably expected to graduate before turning 19.
