The guidelines produce a number from combined income and overnights. A court can move off it, but has to say why.
Child support in Florida is calculated under section 61.30. The statute sets a guidelines schedule based on the parents’ combined net income and the number of children, then allocates the obligation between them in proportion to their incomes.
The section defines gross income broadly, sets the allowable deductions that produce net income, provides the guidelines schedule, and adjusts the result for substantial time-sharing. It permits a court to vary from the guideline amount within a limited range, and beyond that only with written findings explaining why the guideline figure would be unjust or inappropriate.

The inputs decide the number, not argument. Gross income, allowable deductions, health insurance and childcare costs, and overnights — get those right and the calculation largely runs itself.

Support is the most predictable figure in a Florida divorce and the one clients argue about most. The guidelines do the work; when the value inputs are accurate there is very little left to litigate. Therefore, resulting in many cases can settling on this issue when attorneys are present.
The cost to you comes from an inability to timely produce organized documents and evidence. Every time the calculation is redone, it is billed. Having the proper records ready before the first meeting changes what that meeting is for.
Support is usually the cheapest issue to resolve and the most expensive to litigate badly. The figures come from pay records, tax returns and childcare invoices; when those arrive late or incomplete, the calculation is redone, and each redo is billed.
