Florida Child Support Calculator | Guidelines

The Florida child support calculator is a worksheet used by the Florida courts to make a determination as to how much child support is to be paid by a parent in the event of divorce or separation. In order to calculate the amount you may owe, you will need to have your income and costs available. The amount you calculate will only be an estimate. An actual child support order may be different based upon individual circumstances.
