"Net income" = monthly income after allowable deductions. Overnights are nights the children sleep at Parent A's home each year (0–365); the rest are with Parent B.

How it works
The Florida Child Support Calculator estimates guideline support under the state’s income-shares model (Florida Statute 61.30). You enter each parent’s net monthly income, the number of children, and Parent A’s overnights per year. The tool looks up the basic support obligation, splits it by income share, applies a simple overnight adjustment, and shows which parent pays and roughly how much.

The income-shares method
Florida’s approach has three core steps:
- Combine both parents’ net monthly incomes (CN).
- Look up the basic monthly obligation from the Statute 61.30(6) schedule for that combined income and the number of children.
- Split the obligation in proportion to each parent’s share of the combined income.
A parent who earns a larger share of the income is responsible for a larger share of the obligation. The parent who has the children fewer nights typically pays the other parent the difference.
The basic obligation schedule (2024 snapshot)
The statute publishes a long table of basic monthly obligations. A few anchor rows:
| Combined net income (per month) | 1 child | 2 children | 3 children |
|---|---|---|---|
| $2,000 | $417 | $645 | $808 |
| $4,000 | $705 | $1,086 | $1,383 |
| $6,000 | $891 | $1,372 | $1,755 |
| $8,000 | $1,051 | $1,611 | $2,065 |
| $10,000 | $1,190 | $1,818 | $2,333 |
The calculator interpolates between these rows for incomes in between and extends the schedule for incomes above the top row.
Worked example
Parent A nets $4,000/month, Parent B nets $2,500/month, there are 2 children, and Parent A has 110 overnights a year:
- Combined net income CN = 4,000 + 2,500 = $6,500.
- Basic obligation for 2 children at $6,500 (interpolated) is about $1,435/month.
- Income shares: Parent A 61.5%, Parent B 38.5%.
- Timeshare: Parent A 110/365 = 30.1%, Parent B 69.9%.
- Net transfer ≈ 1,435 x (61.5% − 30.1%) ≈ $451/month, paid by Parent A to Parent B.
Overnights and the 20% threshold
When a parent reaches 73 overnights a year (about 20%), Florida switches to a gross-up adjustment that raises the total obligation and credits each parent for direct care during their own time. Balanced overnights tend to shrink the net transfer between parents. This calculator approximates that credit; the official worksheet applies the exact statutory multiplier.
Limitations
This tool models the basic obligation and a simplified overnight credit only. The official Florida guidelines worksheet additionally allocates health-insurance premiums, child-care costs and uncovered medical expenses, and a judge may deviate from the guideline. Treat the result as a starting estimate, not a court order.
Frequently asked questions
How is child support calculated in Florida?+
Florida uses an income-shares model under Statute 61.30. You add both parents' net monthly incomes, look up the basic support obligation from the statutory schedule for that combined income and the number of children, then split it in proportion to each parent's share of the income. Overnights, health insurance and child-care costs adjust the final transfer.
What is the income-shares model?+
The income-shares model assumes children should receive the same proportion of parental income they would have if the parents lived together. Florida first sets a total basic obligation based on combined income, then divides responsibility between the parents according to how much each one earns, so a parent who makes 60% of the income covers about 60% of the obligation.
Do overnights change child support in Florida?+
Yes. When a parent has at least 20% of the overnights (73 or more nights a year), Florida applies a gross-up adjustment that increases the total obligation and credits each parent for time spent directly caring for the children. More balanced overnights generally reduce the net amount transferred between parents.
What net income is used for Florida child support?+
Net income is gross income minus allowable deductions such as taxes, mandatory retirement and union dues, health insurance for the parent, and court-ordered support for other children. It is not take-home pay. Both parents' net incomes are combined to find the basic obligation on the schedule.
Is this calculator the official Florida child support amount?+
No. This is an estimate using a snapshot of the basic obligation schedule and a simplified overnight adjustment. The official Florida child support guidelines worksheet adds health-insurance premiums, child-care and uncovered medical costs and uses the exact statutory gross-up method. A judge can also deviate. Confirm with the court or an attorney.
