Enter what you know and press Calculate Estimate. The calculator estimates each parent's net income, applies the Florida guidelines schedule and shows every step.
- Enter each parent's gross monthly income as Parent A and Parent B.
- Choose the number of children and the parent the children live with most of the time.
- Add monthly work-related child care and the child's health insurance cost, and say which parent pays them.
- If the children spend 73 or more overnights a year (20%) with the other parent, enter that number to use Florida's substantial time-sharing formula.
Your numbers are sent with the form, not placed in the page address, and this site does not store them. The result is a planning estimate; a court or the Florida Department of Revenue decides the actual amount.
New Florida Child Support Laws and Changes for 2026
Looking for new child support laws in Florida for 2026? As of this review in October 2026, we did not find an enacted change to the Section 61.30 guidelines schedule or to the 73-overnight (20%) substantial time-sharing rule that this calculator uses. A 2026 family law bill, CS/SB 1128, dealt with court procedures for time-sharing hearings and died in committee on March 13, 2026; the Florida Senate's bill page does not list Section 61.30 among the statutes it would change.
Laws can change after a review date, so check the Florida Statutes and the Florida Department of Revenue before relying on an estimate for a court filing. An existing order does not change automatically when guidelines change; modification is a separate request to the court.
How Florida Calculates Child Support Under Section 61.30
Florida uses the income shares model in Florida Statute § 61.30: the children should receive roughly the share of parental income they would have had if the household were together, so both parents' net incomes are combined and each pays their share of the minimum need. The steps are:
- Gross income (Section 61.30(2)) includes salary and wages, bonuses and commissions, business income, disability, workers' compensation and unemployment benefits, pensions and Social Security, spousal support received, interest, dividends, rental income and more. Public assistance is excluded.
- Allowable deductions (Section 61.30(3)): federal, state and local income taxes, FICA or self-employment tax, mandatory union dues, mandatory retirement, health insurance payments (excluding coverage for the minor child), court-ordered support for other children, and court-ordered spousal support paid.
- Net income is gross income minus the allowable deductions. Combined net income is the two net incomes added together.
- Minimum child support need comes from the guidelines schedule for the combined net income and the number of children.
- Add work-related child care and the child's health insurance costs (Sections 61.30(7) and (8)).
- Each parent's share equals their net income divided by combined net income (Section 61.30(9)); their dollar share is the total need times that percentage (Section 61.30(10)). Costs a parent has already paid are credited against their share.
How this calculator estimates net income: it subtracts federal income tax (2025 brackets and the standard deduction) and FICA from gross income. Florida has no state personal income tax. Your real net income may differ if you have other deductions, so the estimate is approximate. Between the schedule's $50 rows the calculator interpolates linearly.
Florida Child Support Guidelines Schedule: Sample Amounts
The table shows the minimum child support need from the Section 61.30(6) schedule at several combined net incomes. This is the starting point before child care, health insurance and each parent's percentage share are applied.
| Combined monthly net income | 1 child | 2 children | 3 children | 4 children | 5 children | 6 children |
|---|
| $800 | $190 | $211 | $213 | $216 | $218 | $220 |
| $900 | $213 | $302 | $305 | $309 | $312 | $315 |
| $1,300 | $300 | $467 | $584 | $659 | $688 | $695 |
| $3,300 | $701 | $1,090 | $1,364 | $1,537 | $1,677 | $1,793 |
| $5,800 | $1,102 | $1,705 | $2,134 | $2,406 | $2,627 | $2,807 |
| $10,000 | $1,437 | $2,228 | $2,795 | $3,148 | $3,432 | $3,666 |
The full schedule starts at $800 and runs to $10,000 of combined monthly net income in $50 steps, with columns for one to six children.
Florida Child Support Examples
Example 1: 2 children, no extra costs
Parent A (children live with A) has net income $1,300; Parent B has $2,000. Combined net income is $3,300, and the schedule gives $1,090 for two children. Parent B's share is 60.6%: $660.61 a month.
Example 2: 3 children with child care
Combined net income $5,800 (A $2,300, B $3,500). The schedule amount for three children is $2,134; adding $400 of child care paid by Parent A gives $2,534. Parent B's 60.3% share is $1,529.14 a month.
Example 3: Combined net income above $10,000
A has $4,000 and B has $8,000 (combined $12,000), 2 children. The schedule amount at $10,000 is $2,228, plus 7.5% of the $2,000 above $10,000 ($150) = $2,378. Parent B's 66.7% share is $1,585.33 a month.
Example 4: Substantial time-sharing
Same incomes as Example 2, 1 child, and the child spends 146 overnights a year (40%) with Parent B. The schedule amount for one child at $5,800 is $1,102; × 1.5 = $1,653. Parent A's obligation × B's share of overnights = $262.20, Parent B's obligation × A's share of overnights = $598.50. The difference is $336.30 a month, paid by Parent B.
These are illustrations produced from the schedule, not court rulings. Use the calculator above to enter your own numbers.
Florida Child Support Above $10,000 Combined Net Income
The guidelines schedule ends at $10,000 of combined monthly net income. Above that, Section 61.30(6)(b) says the obligation is the schedule amount at $10,000 plus a percentage of the combined net income above $10,000:
| Number of children | Percentage of income above $10,000 |
|---|
| 1 | 5.0% |
| 2 | 7.5% |
| 3 | 9.5% |
| 4 | 11.0% |
| 5 | 12.0% |
| 6 | 12.5% |
The calculator applies these percentages automatically for high-income cases.
Florida Child Support With 50/50 Custody or Substantial Time-Sharing
If you are looking for a 50/50 child support calculator for Florida or a Florida child support calculator with overnights, this is the rule that matters. Under Section 61.30(11)(b), when each parent has the child for at least 20% of the overnights in a year (73 nights), the court uses a substantial time-sharing adjustment:
- Work out each parent's obligation from the schedule, leaving out child care and health insurance, and multiply it by 1.5.
- Calculate each parent's percentage of overnights.
- Multiply each parent's obligation by the other parent's percentage of overnights.
- The difference is the transfer between the parents.
- Calculate the net child care and health insurance each parent owes, then adjust the transfer by that amount.
- The court can still deviate for factors such as the obligee's low income, the likelihood the schedule will be followed, and whether all children share the same schedule.
Enter the overnights the child spends with the parent who does not have the child most of the time, and the calculator follows steps 1 to 5. Below 73 overnights, the standard calculation is used.
Low Income and Imputed Income in Florida
Low income. If the paying parent's net income is less than the amount in the guidelines schedule, Section 61.30(6)(a) says the parent is ordered to pay an amount decided case by case, to establish the principle of payment. The payment is the lesser of the parent's dollar share of the minimum need and 90% of the difference between the parent's monthly net income and the federal poverty guideline for a single individual. The 2026 federal poverty guideline for one person is $15,960 a year ($1,330 a month). This calculator does not estimate that case; if combined net income is under $800 it will tell you so.
Imputed income. Under Section 61.30(2)(b), a court may impute income to a parent who is voluntarily unemployed or underemployed, and if no information is available there is a rebuttable presumption of income equal to the median of year-round full-time workers. Incarceration is not treated as voluntary unemployment. Enter the income you expect a court to use.
When a Court Can Change the Florida Guideline Amount
Section 61.30(11)(a) lets the court adjust the guideline amount based on factors such as extraordinary medical, psychological, educational or dental expenses; the child's independent income; support paid for another parent; seasonal income variations; the child's age and special needs; the parents' total available assets; tax credits and dependency exemptions; time-sharing arrangements; a guideline result requiring payment of more than 55% of gross income; and any other adjustment needed for an equitable result.
What This Florida Estimate Does Not Include
- Exact net income: taxes are estimated from gross income, and other allowable deductions are not applied.
- Combined net income under $800 (the court decides case by case).
- Deviations under Section 61.30(11)(a) and the court's discretion in shared time-sharing cases.
- Support for other children or spousal support you pay, which reduce net income in an actual case.
- Social Security credits for benefits paid to the child (Section 61.30(10)(b)).
- Arrears, interest and retroactive support. People also search for a "Florida alimony and child support calculator"; this tool estimates child support only.
Frequently Asked Questions About Florida Child Support
Is this the official Florida child support calculator?
No. ChildSupportCalculator.xyz is an independent tool and is not affiliated with the state. It applies the guidelines schedule and rules in Florida Statute 61.30. The Florida Department of Revenue Child Support Program and the court decide actual amounts.
How is child support calculated in Florida?
Florida uses the income shares model. Each parent's net income is found by subtracting allowable deductions from gross income, the net incomes are added, the minimum need is read from the guidelines schedule, child care and health insurance are added, and each parent pays their share by net income percentage.
Does Florida use gross or net income?
Both: you start with gross income and subtract allowable deductions such as income taxes, FICA, mandatory union dues and mandatory retirement to reach net income. The guidelines schedule is based on combined net income.
How does 50/50 custody affect child support in Florida?
When each parent has at least 20% of the overnights (73 nights), the substantial time-sharing formula applies: each parent's obligation is multiplied by 1.5 and then by the other parent's share of overnights, and the difference is paid with an adjustment for child care and health insurance. Enter the overnights in the calculator to see it.
How many overnights are needed for the time-sharing adjustment in Florida?
At least 20% of the overnights in a year, which is 73 nights, for each parent.
What is the highest income on the Florida schedule?
$10,000 of combined monthly net income. Above that, Section 61.30(6)(b) adds a percentage of the income above $10,000: 5.0% for one child, 7.5% for two, 9.5% for three, 11.0% for four, 12.0% for five and 12.5% for six.
What if combined net income is below $800 in Florida?
The schedule starts at $800. If the paying parent's net income is less than the schedule amount, the court sets support case by case, and the payment is the lesser of the parent's share of the minimum need and 90% of the amount their net income exceeds the federal poverty guideline for a single person. This calculator does not estimate that case.
Does Florida include child care and health insurance in child support?
Yes. Work-related child care and the child's health insurance costs are added to the minimum need and divided between the parents. A parent who already pays them is credited with that amount.
Can income be imputed in Florida?
Yes. A court can impute income to a parent who is voluntarily unemployed or underemployed. If no information is available there is a rebuttable presumption of income equal to the median income of year-round full-time workers.
Does this Florida calculator include alimony, arrears or modification?
No. It estimates a new guideline amount only. Alimony, past-due support and modification depend on your case; check with the court or an attorney.
Are there new child support laws in Florida in 2026?
We did not find an enacted 2026 change to the Section 61.30 guidelines schedule or the 73-overnight time-sharing rule. A 2026 family law bill, CS/SB 1128, died in committee on March 13, 2026. Check the Florida Statutes for later updates.
