Florida uses an income-based formula, not a judge's discretion
Florida child support is calculated using a statutory guideline set by state law. The amount depends on both parents' gross monthly income, the number of children, and how much time each parent spends with the children. A judge does not decide the amount based on what seems fair — they apply a formula. The formula produces a base amount, and then adjustments are made for things like health insurance costs, childcare, and overnight parenting time.
The calculation starts with gross monthly income from both parents. This includes wages, salary, bonuses, commissions, self-employment income, rental income, and certain benefits. It does not include child support or spousal support the parent is already paying to someone else. Once both parents' incomes are known, the guideline percentage is applied based on the number of children.
Key Takeaways
- Florida calculates child support by adding both parents' gross monthly income and applying a percentage based on the number of children: 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more.
- The base amount is then adjusted for childcare costs, health insurance premiums, and the number of overnight visits each parent has with the children.
- If one parent earns significantly more than the other, the court may cap income at a certain level or apply a different calculation above that cap.
- The paying parent's income must be documented with recent pay stubs, tax returns, or a sworn financial affidavit, and changes in income can lead to a modification of the order.
The guideline percentages and combined income threshold
Florida's guideline starts with a combined parental income — the total of both parents' gross monthly income. The state applies a percentage to this combined amount based on the number of children:
| Number of Children | Percentage of Combined Income |
|---|---|
| 1 child | 20% |
| 2 children | 25% |
| 3 children | 30% |
| 4 children | 35% |
| 5 or more children | 40% |
This percentage applies to combined income up to a threshold. As of recent years, that threshold is around $160,000 per month in combined income, though this amount changes periodically. If combined income exceeds the threshold, the court may apply the percentage to the amount over the threshold or use a different calculation — this is called the income cap adjustment, and judges have discretion in how to handle income above the cap.
Once the base amount is calculated, it is divided between the parents based on their individual income shares. For example, if the combined income is $5,000 per month and there are two children, the base is $1,250 (25% of $5,000). If one parent earns $3,000 and the other $2,000, the parent earning $3,000 pays 60% of the base ($750), and the parent earning $2,000 pays 40% ($500).
Adjustments for childcare, health insurance, and parenting time
The base amount is not the final number. Florida law requires adjustments for specific costs and circumstances. Childcare expenses — the cost of daycare or after-school care necessary for a parent to work — are added to the base. Each parent pays their income share of this cost. For example, if childcare costs $800 per month and one parent earns 60% of combined income, that parent pays $480 of the childcare cost.
Health insurance premiums for the children are also added. The parent who carries the insurance on their policy pays their income share of the premium cost. If both parents carry insurance, only the cost of the parent's policy is added, not both.
Parenting time — the number of overnight visits each parent has — reduces the paying parent's obligation. If the non-paying parent has the children at least 40% of the time (roughly 146 nights per year), the base amount is reduced. The reduction is calculated by multiplying the base by the percentage of time the non-paying parent has the children. For example, if the non-paying parent has the children 50% of the time, the base is reduced by 50%.
How to document income for the calculation
Income must be proven with documents. The most common proof is recent pay stubs — typically the last two or three months. Self-employed parents provide tax returns from the past two years and sometimes a profit-and-loss statement for the current year. If income is irregular or the parent is not currently working, a sworn financial affidavit — a document signed under oath — is used to state the income amount.
If a parent claims they cannot work or are underemployed, the court may impute income — assign an income amount based on their education, work history, or the local job market — rather than accept their stated income. This prevents a parent from deliberately reducing income to lower their child support obligation.
Both parents must exchange financial documents before a hearing or settlement. If one parent refuses to provide documents or lies about income, the other parent can request a hearing to compel disclosure or ask the judge to impute income based on available evidence.
When income changes or the order needs updating
A child support order can be modified if there is a substantial change in circumstances. In Florida, a change of 10% or more in either parent's income usually meets this threshold. If a parent loses a job, gets a significant raise, or has a major change in parenting time, either parent can request a modification.
To modify an order, the requesting parent files a motion with the court and provides updated financial documents. The court recalculates using the new income and circumstances. Modifications are typically effective from the date the motion is filed, not retroactively to when the change occurred, though a court may order back payment in some cases.
If a parent stops paying or falls behind, the other parent can file for enforcement. The court can order the delinquent parent to pay the arrears, plus interest and attorney fees. Unpaid child support can also result in wage garnishment, suspension of a driver's license, or other enforcement actions.
Income cap and high-income cases
When combined parental income exceeds the statutory cap (currently around $160,000 per month), the court is not required to apply the guideline percentage to the entire amount. Instead, the judge may apply the percentage only to income up to the cap and then decide how to handle the excess. This is discretionary, and different judges handle it differently.
In high-income cases, the court considers factors such as the standard of living the child enjoyed before the parents separated, the financial resources of both parents, and the child's actual needs. A child whose parents earn $300,000 per month may receive more support than the guideline would suggest, but the court has flexibility in determining the amount.
Frequently Asked Questions
Does child support include college expenses?
Florida child support typically ends when the child turns 18 or graduates high school, whichever is later. College expenses are not automatically included in child support. However, parents can agree to pay for college, or a court can order it if the parents have the financial means and the child is likely to attend. This requires a separate agreement or court order, not the standard guideline calculation.
What if one parent is unemployed or disabled?
If a parent is unemployed, the court may impute income based on their work history and local job availability rather than accept zero income. If a parent is disabled and receiving Social Security, that income counts toward the calculation. If a parent is truly unable to work, the court may impute income at minimum wage or a similar baseline, depending on the circumstances.
Can child support be modified if the paying parent remarries?
Remarriage itself does not change child support. However, if remarriage changes a parent's income or expenses, that change may be grounds for modification. For example, if a parent's new spouse's income allows the parent to reduce work hours, the court may consider that. But the new spouse's income is not added to the calculation — only the parent's own income counts.
How is self-employment income calculated?
Self-employed parents report income based on their tax returns. The court typically uses net income (revenue minus legitimate business expenses) rather than gross revenue. If a parent's business is new or income is highly variable, the court may average income over multiple years or request current financial statements to determine a reasonable income figure.
What happens if the parents share custody equally?
If both parents have the children 50% of the time, the base child support amount is reduced by 50%. However, the parent with higher income still typically pays the other parent. The calculation uses each parent's income share of the reduced base, so the higher-earning parent pays the difference in their income shares applied to the reduced amount.
