Florida Child Support Guidelines Explained

Florida calculates child support using the income shares model, which is based on the principle that a child should receive the same proportion of parental income that the child would have received if the parents lived together. The governing statute, Florida Statutes Section 61.30, provides a detailed framework for determining each parent’s support obligation, including a guideline schedule, adjustments for time-sharing, add-on expenses, and factors that allow the court to deviate from the calculated amount.

Understanding how Florida’s child support guidelines work is critical for any parent going through a divorce or paternity action. This article explains each component of the calculation and the circumstances under which a court may adjust the guideline amount.

The Income Shares Model

Florida’s income shares model works by combining both parents’ net incomes to determine the total amount that would be spent on the child if the family were intact. The child support guideline schedule — a table included in FL Stat 61.30(6) — specifies a minimum child support need based on the combined net income and the number of children.

The basic steps are:

1. Calculate each parent’s net monthly income
2. Combine both parents’ net incomes
3. Look up the minimum child support need on the guideline schedule based on combined income and number of children
4. Determine each parent’s percentage share of the combined income
5. Allocate the child support need proportionally based on each parent’s income share
6. Apply adjustments for time-sharing, health insurance, and childcare

The parent who spends less time with the child (or has the higher income share) typically pays child support to the other parent.

Net Income Calculation

The foundation of the child support calculation is each parent’s net income. FL Stat 61.30(2) defines gross income broadly and then allows specific deductions to arrive at net income.

Gross income includes:

• Salary, wages, bonuses, commissions, and tips
• Business income (revenue minus ordinary and necessary expenses)
• Disability benefits, workers’ compensation, and unemployment compensation
• Pension and retirement income
• Social Security benefits
• Spousal support received from a previous marriage
• Rental income
• Interest and dividends
• Trust income
• Any other source of income

Allowable deductions from gross income include:

• Federal, state, and local income taxes (based on the filing status most beneficial to the parent)
• Federal insurance contributions (FICA) and self-employment taxes
• Mandatory union dues
• Mandatory retirement contributions
• Health insurance premiums (excluding the portion attributable to the child, which is handled separately)
• Court-ordered support for other children actually being paid

After subtracting these deductions from gross income, the result is each parent’s net monthly income.

The Guideline Schedule

FL Stat 61.30(6) contains a schedule that specifies the minimum child support need based on combined net income (from $800 to $10,000 per month) and the number of children (one through six). For combined net incomes above the schedule’s range, the court exercises discretion in setting the support amount but must consider the needs of the child and the standard of living the child would have enjoyed had the family remained intact.

For example, for two parents with a combined net monthly income of $5,000 and two children, the guideline schedule specifies a minimum child support need. Each parent’s share is then determined proportionally. If one parent earns 60 percent of the combined income and the other earns 40 percent, the higher-earning parent is responsible for 60 percent of the guideline amount.

Substantial Time-Sharing Adjustment

One of the most significant adjustments in Florida’s child support calculation is the substantial time-sharing adjustment, which applies when the parent who would otherwise pay support exercises time-sharing for 20 percent or more of the overnights in a year — that is, 73 or more overnights.

The rationale is straightforward: a parent who has the child for a significant portion of the year incurs direct costs for housing, food, transportation, and other expenses during that time. The child support formula accounts for this by reducing the paying parent’s obligation.

The calculation under FL Stat 61.30(11)(b) works as follows:

1. Determine each parent’s share of the minimum child support need based on their percentage of combined net income
2. Multiply each parent’s support share by 1.5 to create an adjusted support amount
3. For each parent, multiply the other parent’s adjusted support amount by the percentage of overnights that parent exercises
4. The difference between the two resulting figures determines the child support obligation

This formula produces a sliding scale: the more overnights the paying parent exercises, the lower the support obligation. At exactly 50/50 time-sharing, the higher-earning parent still pays support, but the amount is significantly reduced compared to a schedule with fewer overnights.

The substantial time-sharing adjustment underscores the close relationship between the parenting plan and the child support calculation. For more on how time-sharing schedules work in Florida, see our article on Florida parenting plan requirements.

Healthcare and Childcare Add-Ons

In addition to the base child support amount, Florida law requires certain expenses to be added to the calculation and allocated between the parents:

Health insurance premiums. The cost of adding the child to a parent’s health insurance policy is added to the minimum child support need and divided proportionally. If neither parent has access to reasonable employer-provided coverage, the court determines how health insurance will be obtained and paid for.

Unreimbursed medical expenses. Non-covered medical, dental, orthodontic, vision, and prescription costs are typically divided between the parents in proportion to their income shares, unless the court orders a different allocation.

Childcare costs. Daycare, after-school care, and summer camp expenses incurred because a parent is working, looking for work, or attending school are added to the calculation and divided proportionally. These costs must be reasonable and necessary.

These add-ons can substantially increase the total child support obligation, particularly when childcare costs are high or the child has significant medical needs.

Deviation Factors

The guideline amount is presumed to be correct, but either parent can ask the court to deviate upward or downward by up to 5 percent without written findings. Deviations greater than 5 percent require the court to make specific written findings explaining why the guideline amount is unjust or inappropriate.

FL Stat 61.30(11)(a) lists factors the court may consider when deciding whether to deviate:

• Extraordinary medical, psychological, or educational expenses of the child
• Independent income of the child
• The obligee parent’s low income and limited assets, which may warrant a lower support amount if the paying parent’s ability to pay is constrained
• Seasonal variations in a parent’s income or expenses
• The age of the child, considering the greater needs of older children
• Special needs (before or after age 18) of any child covered by the support order
• The total assets available to both parents and the child
• The impact of the federal tax structure (earned income credit, dependency exemptions, etc.)
• Any other adjustment needed to achieve an equitable result

Courts take deviation requests seriously and will not grant them based on speculation or unsubstantiated claims. The parent seeking the deviation must provide evidence supporting their position.

Imputing Income

When a parent is voluntarily unemployed or underemployed — meaning they are capable of earning more but choose not to — the court may impute income to that parent for child support purposes. Under FL Stat 61.30(2)(b), imputing income requires the court to consider:

• The parent’s recent work history
• Occupational qualifications and educational background
• The prevailing earning level in the community for someone with comparable skills and experience
• Whether the parent has the capacity to earn income through reasonable effort

Income will not be imputed to a parent who is incapable of working due to a genuine physical or mental disability, or to a parent who is caring for a child under the age of three when it is not in the best interest of the child for that parent to work.

Imputation is a common issue in Florida child support cases, particularly when one parent has left the workforce or taken a lower-paying job around the time of the divorce. The court does not simply accept a parent’s current income at face value if the evidence shows the parent is capable of earning more.

Retroactive Support

Florida allows the court to award retroactive child support — that is, support dating back to the date the petition was filed or, in paternity cases, back to the date of the child’s birth. Under FL Stat 61.30(17), the court considers the need for retroactive support and the paying parent’s ability to pay.

Retroactive support can result in a significant lump-sum obligation, particularly in paternity cases where the father was not previously contributing to the child’s expenses. The court has discretion to determine how retroactive support is paid, whether in a lump sum or through installments added to ongoing monthly payments.

What to Do Next

If you are involved in a child support matter in Florida, take these steps:

1. Gather income documentation. Collect recent pay stubs, tax returns, bank statements, and records of all income sources for both yourself and the other parent. Accurate income information is the foundation of the child support calculation.
2. Track time-sharing carefully. The number of overnights each parent exercises directly affects the child support amount. Keep accurate records of your actual time-sharing schedule.
3. Document add-on expenses. Maintain records of health insurance premiums, childcare costs, and unreimbursed medical expenses. These are allocated between parents as part of the support calculation.
4. Understand your rights. If the other parent is voluntarily underemployed or not disclosing income, you can ask the court to impute income based on their earning capacity.
5. Consult a Florida family law attorney. Child support calculations involve multiple variables and the stakes are significant for both parents and the child. Schedule a free consultation to ensure your child support is calculated correctly under Florida law.
