Child Support Calculator Florida: Free, Instant 2026 Estimate
Florida Child Support Calculator
Free Florida estimate — Official F.S. 61.30 Guideline Table
Wondering how much you’ll pay or receive in child support? Our child support calculator Florida parents trust makes it simple. Just enter each parent’s income, the number of children, and your parenting time, and you’ll get an instant, accurate estimate based on Florida’s official child support formula.
Every family’s situation is different, but the state uses one standard formula for every case. This fl child support calculator walks you through that formula step by step, so you know exactly where your numbers come from — not just what the final amount is.
How Much Is Child Support in Florida?
There’s no flat fee or fixed percentage. How much is child support in Florida depends on a mix of factors: both parents’ net income, how many children are involved, how many overnights each parent has, and who pays for healthcare, daycare, and other costs for the kids.
For most families, monthly payments land somewhere between a few hundred dollars and a couple thousand, depending mainly on combined income and time-sharing. Because the range is so wide, the safest way to know your real number is to run it through a calculator built on Florida’s actual guidelines — not a rough online guess.
How Is Child Support Calculated in Florida?
Florida law (Florida Statute 61.30) lays out a specific formula that judges must follow in almost every case. Here’s what goes into it.
1. Each Parent’s Net Monthly Income
The court starts with gross income for both parents, then subtracts taxes, mandatory retirement contributions, health insurance premiums, and a few other allowed deductions. What’s left is net income — the number actually used in the formula.
That’s why the calculator above asks for your filing status and your own health insurance premium: it uses these to estimate your federal tax and arrive at the net income figure Florida’s formula actually runs on, instead of using your raw gross pay.
2. Number of Children
More children means a higher basic support obligation. The state has a set table that lists an obligation amount based on combined parental income and the number of kids in the case. A child must generally be under 18 (or still in high school) to count.
3. Time-Sharing (Overnights)
If each parent has the child for at least 20% of overnights in a year (73 nights or more), Florida adjusts the calculation to reflect that both households are covering everyday costs. This is why parenting schedules matter just as much as income when you estimate support.
4. Health Insurance, Daycare, and Medical Costs
Whatever a parent already pays toward the child’s health insurance, daycare, or uninsured medical expenses gets factored in and divided based on each parent’s share of the combined income.
5. Support for Other Children
If a parent already has a court-ordered support obligation for a child from a different relationship, Florida credits a small amount back before running the formula, since that income is already committed elsewhere. If this applies to you, use the “Other Children You Already Support” field in the calculator above so your estimate accounts for it.
Step-by-Step: How the Formula Works
Here’s a simplified walkthrough using a sample case, so you can see the logic behind the numbers.
Step 1 — Find net income. Add up gross income, subtract taxes and allowed deductions for each parent.
Step 2 — Combine incomes. Add both parents’ net incomes together to get the combined available income.
Step 3 — Work out each parent’s share. Divide one parent’s income by the combined total to get their percentage of financial responsibility. The other parent covers the rest.
Step 4 — Check the state table. Florida’s Child Support Guidelines Worksheet gives a base monthly obligation for the combined income and number of children.
Step 5 — Split the obligation. Multiply the base obligation by each parent’s percentage from Step 3.
Step 6 — Adjust for overnights. If both parents have at least 20% time-sharing, the numbers are adjusted again based on how many nights the kids spend with each parent. Our calculator applies a close, simplified version of this adjustment to give you a fast estimate — for the exact court-ready figure, a family law professional will run the full worksheet math.
Step 7 — Add extra costs. Health insurance, daycare, and uncovered medical expenses are added in and split by income percentage.
Step 8 — Find the payment. Whichever parent owes more pays the difference to the other parent each month.
Running through all of this by hand is doable, but slow — and one wrong step throws off the whole result. That’s exactly what our calculator handles for you in seconds.
Florida Child Support Guidelines: What’s New in 2025–2026
Florida updates its child support guidelines schedule periodically to reflect the current cost of raising children. If you’re checking numbers for a new case or a modification, always confirm you’re using the current guidelines table and the latest version of the Child Support Guidelines Worksheet, since older figures can be outdated fast. Our calculator is kept up to date with the current schedule, so you don’t have to track the changes yourself.
Child Support for 1 Kid vs. 2+ Kids in Florida
The basic obligation grows with each additional child, but not in a straight line — it increases at a decreasing rate per child as the family gets bigger. A household with combined income of, say, $4,000 a month will owe noticeably more support for two children than for one, but the second child doesn’t simply double the amount. This is another reason a calculator gives a far more reliable number than rough online estimates.
50/50 Custody and Child Support in Florida
A common misconception is that equal time-sharing means no child support is owed. That’s not automatically true. In 50/50 custody situations, Florida still looks at both parents’ incomes. If one parent earns significantly more, they’ll typically still owe support to the other parent — the time-sharing adjustment lowers the amount, but it doesn’t usually eliminate it.
Frequently Asked Questions
Is a child support order always required in Florida?
Yes, in nearly every case where parental responsibility is established, unless support is already being handled through another proceeding, such as a Department of Revenue case.
Can parents agree on their own amount instead of using the formula?
Parents can agree to a number, but a judge won’t approve or enforce it unless it’s close to what the formula produces. Courts rarely approve amounts more than 5% off the guideline calculation without a documented reason.
Does the payment change if a parent’s income changes later?
Yes. Either parent can request a modification if there’s a significant, ongoing change in income, time-sharing, or the child’s needs.
What counts as income for this calculation?
Wages, self-employment income, bonuses, commissions, and most other regular income sources count. The court then subtracts taxes and a short list of allowed deductions to reach net income.
Where can I find the official worksheet?
Florida’s courts publish the Child Support Guidelines Worksheet, which follows the same formula this calculator uses.
