Florida Child Support Calculator 2026 [Free] – Official 61.30 Guidelines + 73 Nights Gross-Up
Use our free Florida child support calculator for 2026 to estimate guideline support under Florida Statute 61.30.
Florida uses the Income Shares model. Therefore, the court combines both parents’ net monthly incomes and then consults the official guideline schedule. For example, the schedule matches combined income from $800 to $10,000 to a minimum child support need. In addition, if combined income exceeds $10,000, the statute adds a percentage of income over $10,000. As a result, our calculator uses the current 2026 schedule and formula for an accurate estimate.
Combined net income • Guideline schedule • Gross-up method for 73+ overnights
How Florida Child Support Is Calculated in 2026:
Florida’s calculation has four steps. First, the court determines gross income. Second, the court subtracts deductions to get net income. Third, the court applies the guideline schedule. Finally, the court adjusts for time-sharing. Because of this process, Florida support reflects both parents’ resources.
Step 1 – Determine Gross and Net Income:
Every calculation starts with monthly gross income. The court includes wages, salary, bonuses, commissions, overtime, tips, disability, workers comp, unemployment, pensions, retirement, and Social Security. In addition, business owners use business receipts minus ordinary expenses. Spousal support received counts as gross income for the recipient. However, public assistance is excluded. Then the court subtracts seven deductions under 61.30 to get net income: federal/state/local income taxes, FICA or self-employment tax, mandatory union dues, mandatory retirement, parent’s own health insurance, court-ordered support for other children actually paid, and alimony paid.
Therefore, each parent’s net income is separate, and the court combines them to get TN
Compare with Texas support guidelines and California parenting time factor. See also Ohio 90+ nights rule and North Carolina Worksheet A/B/C.
Step 2 – Apply the Guideline Schedule $800-$10,000:
Subsection 61.30(6) contains the official table. The table matches combined monthly net income against number of children to produce minimum need. For example, at $5,000 combined, one child is about $1,000 and two children about $1,710 in our embedded schedule. As combined income rises, the basic obligation increases. In addition, each parent’s share is proportional: if Parent 1 earns 60% of combined, Parent 1 pays 60% of basic obligation.
Step 3 – Handle Income Over $10,000:
Many families exceed $10,000 combined. Therefore, Florida law adds a percentage of income over $10,000 to the schedule maximum. For instance, one child adds 5% of income over $10,000, two children 7.5%, three 9.5%, four 11%, five 12%, six 12.5%. As a result, for two children with $14,000 combined, obligation equals schedule maximum for two at $10,000 plus 7.5% of $4,000. In contrast to Texas cap, Florida keeps increasing support with income.
Step 4 – Adjust for Substantial Time-Sharing (Gross-Up):
When a child spends at least 20% of overnights per year with each parent – 73 nights – the statute requires gross-up method under 61.30(11)(b). First, each parent’s share of basic obligation is multiplied by 1.5. Second, that inflated number is multiplied by percentage of overnights child spends with other parent. Third, the difference is the transfer amount. Therefore, substantial time-sharing usually lowers payment because both households spend directly on child. However, if overnights are below 73, standard formula controls without gross-up. For example, 50/50 time with equal incomes can significantly reduce transfer.
Florida Child Support Example:
Suppose Parent 1 net $3,500 and Parent 2 net $2,500. Combined TN = $6,000. For 2 children, basic obligation from schedule is about $1,920. Parent 1 share 58.3% = $1,119, Parent 2 share 41.7% = $801. Without gross-up, Parent 1 pays $1,119 to Parent 2. However, if Parent 2 has 30% time (110 nights), gross-up applies: Parent 1 adjusted $1,1191.530% = $503, Parent 2 adjusted $8011.570% = $841, difference $338 Parent 2 pays? Actually calculation flips. As a result, gross-up reduces support when time is substantial. Therefore, timeshare matters
greatly in Florida.
Health Care, Childcare and Add-Ons:
After basic obligation, Florida adds childcare costs tied to employment and health insurance premiums for children plus unreimbursed medical, dental, prescription costs. In addition, the court adds these costs proportionally based on income shares. For example, a parent earning 65% of combined picks up 65% of add-ons. Because of this rule, total obligation equals basic plus add-ons.

Frequently Asked Questions:
Income Shares model per Florida Statute 61.30. Combine both parents net monthly incomes, apply guideline schedule $800-$10,000, add percentage over $10k (5% for 1 child, 7.5% for 2, 9.5% for 3, 11% for 4, 12% for 5, 12.5% for 6), split proportionally, apply gross-up if 20%+ overnights.
Start with gross wages, salary, bonuses, commissions, overtime, tips, disability, workers comp, unemployment, pensions, Social Security, business income. Deduct income taxes, FICA, mandatory union dues, mandatory retirement, own health insurance, other court-ordered support actually paid, alimony paid.
At least 20% overnights per year with each parent – 73 nights triggers gross-up method under 61.30(11)(b). Each share x1.5 x other parent time, difference is transfer.
No. Even with 50/50, higher earner pays proportional share. However, gross-up significantly reduces payment because both parents spend directly. Therefore, equal time lowers but rarely eliminates support if incomes differ.
About $1,000 basic obligation per schedule, split proportionally. For example, if Parent 1 earns $3k and Parent 2 $2k, Parent 1 pays 60% = $600 before add-ons.
Start at schedule maximum for number of children at $10,000, then add percentage of every dollar over $10k: 5% for 1 child, 7.5% for 2, 9.5% for 3, 11% for 4, 12% for 5, 12.5% for 6.
Yes, added on top of basic obligation. Childcare tied to employment and children’s health premiums plus unreimbursed medical are added proportionally based on income shares.
Yes, if substantial change in circumstances. Either parent can petition under 61.14. DOR review triggers if recalculation changes amount by at least 10% and $25.
At 18, or 19 if still in high school in good faith expected to graduate before 19. Parties can agree to extend. Incapacitated child may get support past majority with court finding.
Estimate only based on 61.30 guideline schedule and gross-up method. Actual order may vary for deviations up to 5% without findings, beyond 5% requires written findings for extraordinary expenses, child age, disability costs, assets, etc. Not legal advice.
