Quick Answer

Florida child support is the combined net income of both parents, matched to the § 61.30(6) schedule for the number of children, split by each parent's percentage of the combined income, then adjusted for child care, the children's health insurance, and overnights. The court may vary the result up to 5% without written findings. The calculator below shows every line. Free consultation: 877-862-7188.

Run the § 61.30 Guidelines

Use net monthly income (line 27 of the Financial Affidavit, Form 12.902(b) or (c)). Column A is the Petitioner and column B is the Respondent on the printed worksheet. Nothing you type leaves your browser.

1. Net monthly income

Gross income minus the § 61.30(3) deductions: income tax, FICA or self-employment tax, mandatory union dues, mandatory retirement, the parent's own health insurance, court-ordered support for other children actually paid, and court-ordered alimony.

Enter 0 if none.

2. Children and overnights

Count only the minor children common to both parents. Overnights are per year and must total 365 or fewer. When each parent has at least 73 overnights, the gross-up method in § 61.30(11)(b) applies automatically.

The schedule stops at six children.
Fills in as 365 minus Parent A's overnights.

3. Child care and health insurance

Monthly figures, entered under the parent who actually pays them. Child care counts only when it is due to employment, a job search, or education that leads to employment (§ 61.30(7)). Health insurance is the children's coverage only, not the parent's own premium. Leave a line at 0 if the court has ordered that cost split separately on a percentage basis.

The Formula

How the § 61.30 Math Works

Standard Method (lines 1 to 9)

Combined net income sets the basic obligation from the schedule. Each parent carries the percentage of it that matches their share of the combined income.

Share = Basic Obligation × (Parent's Net ÷ Combined Net)

Child care, the children's health insurance and noncovered medical costs are added and split the same way, with a credit for what each parent already pays. The parent with fewer than 73 overnights pays their line 9 amount.

Gross-Up Method (lines 10 to 21)

Applies when each parent has at least 73 overnights a year, § 61.30(11)(b).

Transfer = |(1.5 × Basic × ShareA × OvernightsB%) − (1.5 × Basic × ShareB × OvernightsA%)|

The basic obligation is multiplied by 1.5, split by income share, and each parent's share is then multiplied by the other parent's overnight percentage. The difference is the transfer, adjusted for the additional support each parent actually pays.

Between schedule rows. The schedule moves in $50 steps from $800 to $10,000 of combined net income. A combined figure between rows uses the row below it, the convention the Fourth Circuit worksheets follow. Above $10,000 the statute adds a percentage of the excess: 5.0% for one child, 7.5% for two, 9.5% for three, 11.0% for four, 12.0% for five, 12.5% for six.

Deviation. The court may vary the guideline amount up to 5% either way after considering the factors in § 61.30(1)(a). A larger variance needs written findings and a Motion to Deviate, Form 12.943. The § 61.30(11)(a) factors include extraordinary medical or educational expenses, a child's independent income, seasonal income, the age and special needs of the child, the parties' assets, tax credits and the dependency exemption, and any order that would take more than 55% of the payor's gross income.

Low income. If the paying parent's own net income is under $800, § 61.30(6)(a) caps the payment at 90% of the difference between that income and the federal poverty guideline for one person, and the court sets an amount case by case. The calculator flags that situation rather than guessing at it.

Questions

Child Support Calculator FAQ

How is child support calculated in Florida?+
Florida uses the income shares model in § 61.30. Both parents' net monthly incomes are combined, the combined figure is matched to the guidelines schedule for the number of children, and the basic obligation is split in proportion to each parent's income. Work-related child care and the children's health insurance are added and split the same way, with a credit to the parent who pays them.
What is the 73 overnight rule?+
When each parent has the children at least 20% of the overnights (73 of 365), § 61.30(11)(b) requires the gross-up method: multiply the basic obligation by 1.5, split it by income share, multiply each parent's share by the other parent's overnight percentage, and the difference is the transfer, adjusted for child care and health insurance. Lines 10 through 21 of Form 12.902(e) carry the computation.
Gross or net income?+
Net. § 61.30(3) subtracts income tax, FICA or self-employment tax, mandatory union dues, mandatory retirement, the parent's own health insurance premium, court-ordered support for other children actually paid, and court-ordered alimony. Net income is line 27 of the Financial Affidavit. Military pay counts BAH and BAS as gross income.
Is this the official Florida calculator?+
No. Florida does not publish an official online calculator. This tool applies the current § 61.30 schedule and the Form 12.902(e) line sequence to the figures you enter and prints them in worksheet order. The figures you file must be sworn on the Financial Affidavit, and the worksheet filed with the court must be completed on the current Florida Supreme Court approved form.
Can the court order a different amount?+
Up to 5% either way without written findings, after considering the statutory factors. More than 5% requires written findings that the guideline amount would be unjust or inappropriate, and a Motion to Deviate (Form 12.943).
