How to Use the Florida Child Support Calculator: Complete 2026 Guide

Florida calculates child support using the Income Shares Model under Fla. Stat. § 61.30, combining both parents' net monthly incomes to determine a guideline amount from the statutory schedule. For one child with $6,000 combined monthly net income, the base support obligation is $1,121 per month. Each parent pays their proportional share based on their percentage of combined income, with adjustments for health insurance, childcare costs, and overnight time-sharing arrangements exceeding 73 nights per year.

Key Facts: Florida Child Support

How the Florida Child Support Calculator Works

The Florida child support calculator applies the Income Shares Model, which ensures children receive the same proportion of parental income they would have received if the family remained intact. Under Fla. Stat. § 61.30, both parents' net monthly incomes are combined, and the resulting figure is matched to a statutory guidelines chart that establishes the basic monthly support obligation based on the number of children.

The calculation follows these sequential steps:

1. Determine each parent's gross monthly income from all sources
2. Subtract allowable deductions to calculate net income
3. Combine both parents' net incomes
4. Look up the basic support obligation on the guidelines chart
5. Add mandatory expenses (health insurance, childcare)
6. Apply time-sharing adjustments if applicable
7. Allocate the total obligation based on each parent's income percentage

For example, if Parent A earns $4,000 net monthly and Parent B earns $2,000 net monthly, the combined income is $6,000. Parent A is responsible for 67% of the support obligation, while Parent B covers 33%.

Florida Child Support Guidelines Chart: Sample Amounts

The statutory guidelines chart under Fla. Stat. § 61.30 establishes base support obligations that increase with combined income and number of children. These amounts represent the total monthly obligation before adding health insurance and childcare costs.

When combined monthly net income falls below $800, the court determines the support amount at its discretion rather than applying the guidelines chart. For combined incomes exceeding $10,000, Florida applies additional percentages to the excess amount: 5% for one child, 7.5% for two children, and 9.5% for three children, added to the base amount at $10,000.

Step 1: Calculate Gross Monthly Income

Gross income under Fla. Stat. § 61.30 includes virtually all sources of money received by a parent. The statute defines income broadly to capture the true financial capacity of each parent, ensuring children benefit from their parents' complete earning ability.

Sources included in gross income:

• Wages, salary, bonuses, and commissions
• Self-employment income (gross receipts minus ordinary business expenses)
• Overtime pay and tips
• Rental income and royalties
• Pension and retirement benefits
• Social Security benefits (excluding SSI)
• Disability benefits and workers' compensation
• Unemployment compensation
• Alimony received from any source
• Interest and dividend income
• Trust income and annuities
• Reimbursed expenses and in-kind payments that reduce living expenses

Public assistance benefits (TANF, food stamps, SSI) are excluded from gross income calculations. Business owners must report gross receipts minus ordinary and necessary business expenses, not the net profit after discretionary expenses.

Step 2: Calculate Allowable Deductions

Florida permits only specific statutory deductions when converting gross income to net income for child support purposes under Fla. Stat. § 61.30. These deductions are strictly limited to mandatory obligations, not voluntary expenses.

Allowable deductions include:

• Federal, state, and local income taxes (based on actual filing status)
• FICA (Social Security and Medicare contributions)
• Mandatory union dues
• Mandatory retirement contributions required as a condition of employment
• Health insurance premiums for the parent only (not the child)
• Court-ordered support for other children actually being paid

Voluntary retirement contributions, personal expenses, and the child's health insurance are not deductible from gross income. The child's health insurance is instead added to the basic support obligation and shared proportionally.

Step 3: Complete the Child Support Guidelines Worksheet

Form 12.902(e), the official Child Support Guidelines Worksheet, must be filed with the court when requesting child support in any Florida family law proceeding. The worksheet walks parents through each calculation step and must be served on the opposing party within 45 days of filing.

The worksheet requires documentation of:

• Both parents' gross monthly income with supporting evidence (pay stubs, tax returns, W-2s)
• All allowable deductions with verification
• Health insurance costs for the children
• Childcare expenses necessary for employment or education
• Each parent's percentage of combined net income
• Overnight time-sharing schedule

Each parent must also file a Family Law Financial Affidavit (Form 12.902(b) or (c)) disclosing complete financial information. Failure to provide accurate financial disclosure can result in sanctions and recalculation of support based on imputed income.

Step 4: Add Health Insurance and Childcare Costs

Beyond the base guideline amount from the statutory chart, Fla. Stat. § 61.30 requires adding the children's health insurance premiums and work-related childcare costs to the basic obligation. These mandatory add-ons significantly increase the total support amount in most cases.

Health insurance requirements under Florida law:

• The cost of the children's health, dental, and prescription insurance is added to the basic support obligation
• Insurance must be "reasonable in cost," defined as not exceeding 5% of the paying parent's gross income
• The parent who pays the premium receives a credit for the other parent's proportional share
• Noncovered medical, dental, and prescription costs are also added and shared proportionally

Childcare expense requirements:

• Childcare expenses incurred due to employment, job search, or education leading to employment are added
• The childcare must come from a licensed provider
• Before-school, after-school, and daycare programs while parents work qualify
• Summer camps and occasional babysitting typically do not qualify
• Costs are shared based on each parent's percentage of combined net income

For a family with $6,000 combined monthly income, $400 in children's health insurance, and $800 in daycare costs, the total obligation increases from $1,737 (base for two children) to $2,937 per month before time-sharing adjustments.

Step 5: Apply Time-Sharing Adjustments

Florida adjusts child support obligations when both parents have substantial overnight time-sharing with the children under Fla. Stat. § 61.30. The threshold triggering this adjustment is 73 overnights per year, representing 20% of annual overnights.

How the time-sharing adjustment works:

• When each parent has at least 73 overnights, the basic support obligation is multiplied by 1.5 (the "gross-up" method)
• Each parent's support obligation is calculated separately based on their income percentage
• The obligations are offset against each other
• The parent with the higher obligation pays the difference to the other parent

This adjustment recognizes that parents with substantial overnight time directly incur costs for housing, feeding, and caring for children during their parenting time. A parent with 50% overnights (182.5 nights) pays significantly less in cash support than a parent with only minimal visitation because they already spend directly on the child's needs during their time.

For a 50/50 time-sharing arrangement with equal incomes, the cash support payment may approach zero because each parent bears equal direct costs. However, when incomes differ substantially, cash payments still flow from the higher-earning parent to ensure the child experiences similar living standards in both homes.

Imputed Income: When a Parent Is Unemployed or Underemployed

Florida courts impute income to parents who are voluntarily unemployed or underemployed under Fla. Stat. § 61.30. This prevents parents from artificially reducing their child support obligation by earning less than their capacity allows.

The court determines imputed income by examining:

• The parent's recent work history and employment record
• Occupational qualifications, education, and credentials
• Prevailing earnings levels in the community for similar positions
• Prior income levels (records within the last five years)
• Physical or mental capacity limitations

When income information is unavailable or a parent fails to participate in proceedings, the court applies a rebuttable presumption that the parent earns the median income of year-round full-time workers as published by the U.S. Census Bureau. As of 2026, Florida's minimum wage is $14.00 per hour through September 29, 2026, and $15.00 per hour starting September 30, 2026, which translates to approximately $2,427-$2,600 gross monthly income for full-time work.

Important limitations on imputed income:

• Income cannot be imputed higher than what the parent has earned in the past
• Income records older than five years cannot be used
• Incarceration may not be treated as voluntary unemployment
• Courts may refuse to impute income when a parent must stay home with a child due to special needs

Deviation from Guidelines: When Courts Adjust the Amount

Florida judges may deviate from the guideline amount when strict application would be unjust or inappropriate under Fla. Stat. § 61.30. The court has discretion to adjust the calculated amount within specific parameters.

Deviation rules:

• Judges may deviate up to 5% without providing detailed written findings
• Deviations exceeding 5% require written findings explaining why the guideline amount would be unjust or inappropriate
• The court considers all relevant factors including the child's needs, age, and standard of living
• Extraordinary medical expenses may justify upward deviation
• Special needs of a child may warrant increased support

Common factors supporting deviation include:

• A child's special educational needs or private school tuition
• Extraordinary medical, psychological, or dental expenses
• Independent income of the child
• Seasonal variations in a parent's income
• Age of the child affecting total needs
• Significant assets available to either parent
• Impact of IRS dependency exemption allocation

Modifying an Existing Child Support Order

Either parent may petition to modify child support when circumstances change substantially under Fla. Stat. § 61.30. The threshold for modification depends on how much time has passed since the original order or last modification.

Modification thresholds:

• If fewer than 3 years since the order: The change must cause at least a 15% difference (or $50, whichever is greater) from the current order
• If more than 3 years since the order: The change must cause at least a 10% difference (or $25, whichever is greater)

The change in circumstances must be substantial, permanent, and involuntary. Temporary job loss with expectation of reemployment does not typically qualify. Changes must generally have lasted more than one year to demonstrate permanence.

Common grounds for modification include:

• Significant income increase or decrease
• Job loss or disability
• Changes to the time-sharing schedule
• A child reaching majority (18) or graduating high school
• Changes in health insurance or childcare costs
• Remarriage affecting household expenses

Critically, modifications apply only from the date the petition is filed with the court, not retroactively to when the change occurred. Delaying a modification petition can cost thousands of dollars in support that cannot be recovered.

Filing Fees and Court Costs

Filing for child support in Florida requires payment of court fees that vary by county but follow a general structure. As of March 2026, the filing fee for a Petition for Dissolution of Marriage is approximately $408-$418 in most Florida counties, with some variation.

Fee breakdown (Collier County example):

• Dissolution of Marriage filing fee: $408.00
• Summons issuance: $10.00
• Deputy Clerk oath administration: $3.50

Additional costs may include:

• Process server fees: $40-$75
• Mandatory mediation: $200-$350 per party
• Attorney fees if represented
• Certified copies of orders: $2.00 per page

Parents who cannot afford filing fees may petition for a fee waiver using Florida Family Law Form 12.902(a), Motion to Defer Filing Fees. The court reviews financial circumstances and may waive or defer fees for qualifying low-income parties.

Note: Filing fees current as of March 2026. Verify current fees with your local circuit court clerk before filing.

Enforcement: Collecting Unpaid Child Support

Florida provides robust enforcement mechanisms when a parent fails to pay court-ordered child support. The Florida Department of Revenue, Child Support Program handles enforcement for both state cases and private cases registered for enforcement services.

Enforcement tools available:

• Income withholding orders (automatic payroll deductions)
• Interception of federal and state tax refunds
• Suspension of driver's license, professional licenses, and recreational licenses
• Passport denial for arrearages exceeding $2,500
• Credit bureau reporting affecting credit scores
• Bank account and asset seizure
• Contempt of court proceedings with potential jail time
• Property liens

Under Florida law, child support orders automatically include an income deduction order requiring employers to withhold support from wages. This applies even when the parties agree to direct payment, though the court may delay implementation if both parties agree in writing and the paying parent has no prior support defaults.

This child support estimator provides the same calculations used by Florida courts, giving you a reliable preview before filing official paperwork.

To calculate child support accurately:

1. Gather both parents' income documentation (pay stubs, tax returns, self-employment records)
2. Calculate net income after allowable deductions
3. Determine the overnight time-sharing schedule (number of nights with each parent)
4. Enter monthly health insurance costs for the children
5. Enter work-related childcare expenses
6. Review the estimated support amount

The calculator determines your preliminary child support obligation, but courts may adjust this amount based on factors unique to your case. Complex situations involving high incomes, multiple children from different relationships, or special needs children benefit from consultation with a Florida family law attorney.

Frequently Asked Questions

How is child support calculated in Florida?

Florida calculates child support using the Income Shares Model under Fla. Stat. § 61.30, combining both parents' net monthly incomes and applying a statutory guidelines chart. For $6,000 combined monthly income with one child, the base obligation is $1,121 per month, divided proportionally based on each parent's income percentage.

What income counts for Florida child support?

Gross income includes wages, salary, bonuses, commissions, self-employment earnings, rental income, Social Security benefits, pensions, disability payments, alimony received, and virtually all other income sources under Fla. Stat. § 61.30. Public assistance (TANF, food stamps, SSI) is excluded from calculations.

How does overnight time-sharing affect child support in Florida?

When both parents have at least 73 overnights per year (20% time-sharing), Florida applies the gross-up method, multiplying the base obligation by 1.5 and adjusting proportionally. More overnight time with a parent reduces their cash support obligation because they spend directly on the child during their parenting time.

Can I modify child support if my income changes?

Yes, Florida permits modification when circumstances change substantially under Fla. Stat. § 61.30. If fewer than 3 years have passed, the change must cause at least a 15% difference or $50. After 3 years, the threshold drops to 10% or $25. The change must be substantial, permanent, and involuntary.

What happens if I can't afford the filing fee?

Parents who cannot afford the $408-$418 filing fee may petition for a fee waiver using Florida Family Law Form 12.902(a), Motion to Defer Filing Fees. The court reviews financial circumstances and may waive or defer fees for qualifying low-income parties. Filing fee amounts current as of March 2026.

How is income imputed to an unemployed parent in Florida?

Courts impute income to voluntarily unemployed or underemployed parents based on their recent work history, qualifications, and prevailing community earnings under Fla. Stat. § 61.30. When information is unavailable, courts presume income equal to the median of year-round full-time workers per U.S. Census data.

What expenses are added to the base child support amount?

Florida requires adding the children's health, dental, and prescription insurance premiums plus work-related childcare costs to the base guideline amount under Fla. Stat. § 61.30. These expenses are divided proportionally based on each parent's percentage of combined net income.

How do Florida courts handle high-income parents?

The statutory guidelines chart covers combined incomes up to $10,000 monthly. Above $10,000, Florida applies additional percentages to excess income: 5% per child for one child, 7.5% for two children, and 9.5% for three children, added to the base amount calculated at $10,000.

Can a judge deviate from the child support guidelines?

Yes, judges may deviate up to 5% from guidelines without detailed explanation under Fla. Stat. § 61.30. Deviations exceeding 5% require written findings that the guideline amount would be unjust or inappropriate. Special needs, extraordinary medical expenses, and private school tuition may justify deviation.

How is child support enforced in Florida?

The Florida Department of Revenue enforces child support through income withholding orders, tax refund interception, license suspensions (driver's, professional, recreational), passport denial for arrearages over $2,500, credit reporting, bank account seizure, and contempt of court proceedings with potential incarceration.
