Ohio Child Support Calculator 2026 — Free Estimate (Updated)

Are you a parent in Ohio going through a separation or divorce?

One of your biggest questions is: How much child support will I pay or receive?

Ohio has specific guidelines for child support. The state uses an “income shares model.” Both parents contribute based on their income and the number of children.

The formula considers your income, the other parent’s income, custody time, health insurance costs, and child care expenses. Ohio updates its child support guidelines periodically.

Today, I give you a free Ohio Child Support Calculator for 2026.

You enter your income, the other parent’s income, custody time, and other costs.

The calculator shows you:

• Your estimated monthly child support payment
• Which parent pays and which receives
• How parenting time and add-on costs affect the amount

Let me explain how child support works in Ohio.

What is Ohio Child Support? (Simple Explanation)

Child support is money paid by one parent to the other to help cover the costs of raising a child.

In Ohio, both parents have a legal duty to support their children financially.

Child support continues until the child turns 18. If the child is still in high school, support continues until graduation (but not past age 19).

Who pays whom?

Ohio uses an “income shares” model. Both parents’ incomes are combined. Each parent pays their share of the total support obligation.

The parent with more parenting time usually receives support from the parent with less time. But income matters too. A high-earning parent with equal time may still pay.

What does child support cover?

• Basic living expenses (food, housing, clothing)
• Health insurance premiums
• Child care costs
• Unreimbursed medical expenses
• Educational expenses (sometimes)
