How Is Child Support Calculated in Florida?

Quick Answer: Under F.S. 61.30, Florida uses the "Income Shares Model" based on both parents' net income, number of children, healthcare costs, childcare costs, and the time-sharing arrangement. The statute provides a specific formula and guideline tables.

The Florida Child Support Formula (F.S. 61.30)

Florida Statute 61.30 provides mandatory guidelines that courts must follow:

Step 1: Calculate Each Parent's Net Income (F.S. 61.30(2)-(3))

Net Income = Gross Income - Allowable Deductions

Gross Income includes (F.S. 61.30(2)(a)):

  • Salary and wages
  • Bonuses and commissions
  • Self-employment income
  • Rental income
  • Investment income
  • Unemployment benefits
  • Social Security benefits

Allowable Deductions (F.S. 61.30(3)):

  • Federal and state taxes
  • FICA/Medicare
  • Mandatory retirement contributions
  • Health insurance (for yourself)
  • Union dues
  • Court-ordered support for other children

Step 2: Combine Net Incomes

Add both parents' net income together.

Step 3: Look Up Guideline Amount

Florida publishes a table based on combined income and number of children:

Combined Monthly Income1 Child2 Children3 Children
$5,000$873$1,296$1,532
$7,500$1,150$1,719$2,031
$10,000$1,356$2,021$2,427
$12,500$1,535$2,279$2,779
$15,000$1,699$2,520$3,104

Step 4: Calculate Each Parent's Share

Each parent pays their percentage of the total:

Parent's Share = (Parent's Net Income / Combined Net Income) x Guideline Amount

Step 5: Add Healthcare and Childcare

Add actual costs for:

  • Health insurance for children
  • Uncovered medical expenses
  • Childcare (work-related)

Step 6: Adjust for Time-Sharing (F.S. 61.30(11)(b))

Per F.S. 61.30(11)(b), if the non-primary parent has 20% or more overnights (73+ nights/year), the child support obligation is adjusted using the statutory formula to account for the increased expenses borne by that parent.

Real Example Calculation

Scenario:

  • Mother's Net Income: $4,000/month
  • Father's Net Income: $6,000/month
  • Combined: $10,000/month
  • 2 children
  • Father has 25% overnights
  • Health insurance: $300/month (paid by Mother)
  • Childcare: $800/month

Calculation:

Guideline amount for $10,000 + 2 kids: $2,021
Father's share: 60% x $2,021 = $1,212.60
Father's share of insurance: 60% x $300 = $180
Father's share of childcare: 60% x $800 = $480
Time-sharing adjustment: -25% reduction
Father's payment: Approximately $1,405/month

Deviations from Guidelines (F.S. 61.30(1)(a))

Under F.S. 61.30(1)(a), courts can deviate from guidelines (up or down by 5%) when the guideline amount is "unjust or inappropriate." Factors include:

  • Extraordinary medical, psychological, or educational expenses
  • Child's special needs
  • Significant age difference between children
  • Seasonal income variations
  • Assets available for support
  • Total support exceeding 55% of gross income
  • Independent income of the child
Statutory Note: Any deviation must be justified in writing with findings of fact.

Modifying Child Support (F.S. 61.14)

Under F.S. 61.14, you can petition to modify child support if:

  • Income changes by 15% or more, OR
  • Support would change by $50+ per month
  • Child's needs substantially change
  • Time-sharing schedule changes significantly
  • Other substantial change in circumstances

Frequently Asked Questions

How is child support calculated in Florida?

Under F.S. 61.30, Florida uses the Income Shares Model. Both parents' net incomes are combined, then looked up in statutory guideline tables based on number of children. Each parent pays their percentage, adjusted for healthcare, childcare, and time-sharing (F.S. 61.30(11)(b) adjustment for 20%+ overnights).

What income is used to calculate child support in Florida?

Under F.S. 61.30(2)(a), gross income includes salary, bonuses, self-employment income, rental income, investments, and benefits. F.S. 61.30(3) allows deductions for taxes, FICA, mandatory retirement, health insurance for yourself, and support for other children. The result is your 'net income' for child support.

Does time-sharing affect child support in Florida?

Yes. Under F.S. 61.30(11)(b), if the non-primary parent has 20% or more overnights (73+ nights per year), child support is adjusted using a statutory formula. More time-sharing typically means lower support payments to account for the paying parent's direct expenses.

Can child support be changed in Florida?

Yes. Under F.S. 61.14, you can petition to modify child support if there's a substantial change in circumstances—specifically a 15%+ change in income or $50+ monthly change in support, significant change in time-sharing, or substantial change in the child's needs.
