Child Support Calculation

Florida Child Support Calculator

To calculate Florida child support, enter the take home income of both parents, healthcare cost for the children (only the children), and any daycare costs. Also enter the amount of overnights with the non-majority parent (secondary residential parent). The calculated child support is paid from the non-majority parent (secondary residential parent) to the majority parent (primary residential parent).

The calculator has been updated for the new 2010 child support law.

*** The parent that has the children most of the time is the majority parent


** Results:   Non Custodial Parent = Non Majority Parent

This online child support calculator will not work for combined incomes under $650/month or over $10,000/month. See notes below for incomes exceeding the maximum amount.

The actual child support amount is dependant on other factors which are not addressed by this basic calculation. This service is intended to give a rough estimate of child support and does not substitute for individualized legal advice. The actual child support amount you pay or receive is determined by a family law court.

Common Questions About Child Support


I cannot afford this amount of child support. What now?


Calculation of child support in Florida is dependent only on income. Most expenses do not affect the support amount. A couple of exceptions to this rule are reductions based on other children you support, unusual and necessary personal expenses (such as medical), or other extraordinary circumstances. Other than that, the courts require you to pay the standard Florida guidelines amount of support. There are some exceptions, but a child support attorney would be best able to explain them.


I also pay alimony. Does that affect my child support payment?


The income used to calculate payment of child support is the level of income remaining after alimony is taken out. So alimony payments do reduce child support. There is an interaction between alimony and child support that sometimes can work toward your advantage.


I am remarried, or my spouse is remarried. Does the other persons income figure into child support calculations?


No. Only the parents income is used for support calculations.  There is still a law on the books that allows consideration of any income – no matter what the source. But in practical matters the only thing that counts is each parent’s income.


Can child support be modified?


Yes. Anytime the incomes change, child support can be recalculated and modified . The rules allow you to file for a modification anytime child support would change by $50 or 15%.
