Why is this organized by state instead of one nationwide child support calculator?

Because child support rules are jurisdiction-specific. Income definitions, deduction categories, caps, and adjustment tables can differ by state, so a single nationwide formula would be misleading.

Which states are covered?

Texas, Florida, and California. Each state has its own page with its own inputs, scope, and disclaimers.

How do the Texas, Florida, and California pages differ?

Texas follows the public Texas OAG monthly calculator for a single source of income. Florida follows a worksheet-style path built around both parents' net monthly income. California is narrower and covers only the 2024 new-guideline core path.

Does this hub cover Canada too?

No. These pages cover the United States only. Canada uses a different legal and administrative structure, so U.S. state calculators do not apply there.

Child Support Calculator

To estimate child support in the U.S., choose a state-specific calculator from the list below. Each state's rules, income inputs, time-share inputs, caps, and adjustment tables differ, so pick the page for your state — calculators are available for Texas, Florida, and California, each with its own scope and disclaimers.

How to use these calculators

Child support is not a generic money calculation: the rules depend on the state, so start by choosing your state.

1. Start with the state, not the formula

Choose the state first because child support guidelines, deductions, caps, and adjustment rules vary by jurisdiction.

2. Use the state-specific calculator and explanation

Each state page pairs the calculator with an explanation, official references, and an FAQ for that state.

3. Treat every result as an estimate

Even when a page mirrors a public official calculator, the actual amount set or approved by the court may differ.

Important notes

These calculators are available in English only and cover the United States only.

The Texas page follows the public Texas OAG monthly calculator for single-source-income cases.

The Florida page gives a worksheet-style estimate based on both parents' net monthly income, shared child costs, credits already paid, and substantial time-sharing logic.

The California page estimates the 2024 new SB 343 core path only; it does not replicate every section of the official calculator.
