Children (1–6)

Each parent's annual gross income

Parent A — annual gross income

Parent B — annual gross income

Ohio works from annual gross income (wages, self-employment, averaged overtime/bonuses, unemployment, workers' comp, Social Security disability/retirement). This estimator does not apply the income adjustments for other children, spousal support paid, or health-insurance premiums (R.C. 3119.01; JFS 07766).

In the standard case, which parent pays support?

Parent A Parent B

Does the paying parent have a court order for 90+ overnights per year?

Yes — apply the 10% parenting-time reduction (R.C. 3119.051)

Ohio applies a flat 10% reduction to the paying parent's obligation when a court order gives that parent at least 90 overnights a year. Near-equal (50/50) time can support a further deviation, but that is left to the court's discretion.

How this calculator works

Ohio calculates child support using the income shares model under R.C. 3119.021source verified 2026-07-20. The state estimates what two parents would have spent on their child if they lived together, then splits that amount between them in proportion to each parent's income. Every Ohio order is built on the JFS 07768 worksheet.

Step by step

1. Add up each parent's annual gross income from nearly all sources, then subtract specific adjustments (a credit for other children, health-insurance premiums, and spousal support paid) to reach adjusted income (R.C. 3119.01; JFS 07766, Rev. 4/2026).

2. Find the combined income and match it to the JFS 07767 (Rev. 6/2023) basic schedule, which lists a yearly support figure for every combined income from $8,400 up, in $600 steps, for one to six children.

3. Apply the "lower-of" rule (line 18d): each parent's basic obligation is the lower of the schedule amount for their own income alone, or their income-share percentage of the combined obligation — a built-in protection for lower earners.

4. A parent with a court order for 90 or more overnights has their obligation reduced by 10% (R.C. 3119.051).

5. Add work-related child care (shared by income) and a cash medical support obligation of $510.21 per child per year (JFS 07766, Table 3), then divide by twelve for the monthly order.

Worked example — One child, Parent A earns $60,000/year, Parent B earns $40,000/year (combined $100,000), Parent A pays.

Combined income: $100,000. The JFS 07767 schedule amount for one child at $100,000 is about $13,202/year. Parent A earns 60% of the combined income, so Parent A's income share is $7,921 — and because that is lower than the schedule figure for Parent A's own income ($9,937), the "lower-of" rule uses $7,921. Adding cash medical support ($510.21 × 60% ÷ 12 = $25.51/month), Parent A's estimated total order is about $685.59/month.

What changed in the 2023 update

If you've seen older Ohio figures, current amounts are higher. Ohio's guideline was overhauled in 2019 (H.B. 366) and is refreshed every four years. The 2023 update raised schedule amounts by roughly 11% to 23% versus the 2019 table — driven by inflation, newer child-rearing cost data, and 2018 federal tax changes — and lifted the self-sufficiency reserve from $13,780 to $15,764. This calculator uses the current JFS 07767 (Rev. 6/2023) schedule, not the outdated 2019 figures still shown on many law-firm pages. ODJFS 2023 Guidelines Review, verified 2026-07-20

Estimation limits

This tool interpolates between the schedule's $600 income steps, the proportional method the official manual permits; results are estimates, not a court order.
It does not apply the income adjustments for other children, spousal support paid, or the detailed health-insurance premium adjustment (5% reasonableness cap).
It does not model imputed income, split parenting (JFS 07769), families with seven or more children, or discretionary deviations under R.C. 3119.22–.231.
Above the schedule maximum ($336,000 combined), the court sets the amount case-by-case; this tool uses the top-of-schedule figure as a floor.

Frequently asked questions

How is child support calculated in Ohio?

Ohio uses an income shares model under R.C. 3119.021: you add both parents' gross incomes, look up the basic amount for the combined income and number of children on the JFS 07767 schedule, and split it in proportion to each parent's income — with adjustments for parenting time, child care, and cash medical support.

How is child support calculated with 50/50 custody in Ohio?

Ohio has no automatic "equal time = no support" rule. The guideline still runs; a parent with a court order for 90+ overnights gets a flat 10% reduction (R.C. 3119.051), and a judge may grant a further deviation for near-equal time, but that part is discretionary.

How much is child support for one or two children in Ohio?

It depends entirely on the combined income and the income split. The schedule covers one through six children, and $510.21 per child per year in cash medical support is added. Enter your numbers above for a specific estimate.

What is the minimum child support order in Ohio?

$80 per month for very low incomes (combined income under $8,400 a year), with a sliding-scale minimum inside the self-sufficiency reserve (R.C. 3119.06).

Does Ohio child support include health insurance and medical costs?

Yes. A separate cash medical support obligation of $510.21 per child per year covers ordinary medical costs and is part of nearly every order. Health-insurance premiums are handled as an income adjustment, considered reasonable up to 5% of the paying parent's income.

What income counts for Ohio child support?

Gross income from nearly all sources — wages, self-employment, averaged overtime and bonuses, unemployment, workers' comp, and Social Security disability/retirement — minus specific adjustments for other children, health-insurance premiums, and spousal support paid (R.C. 3119.01).

Why did Ohio child support amounts go up?

The 2023 quadrennial update raised schedule amounts about 11–23% versus the 2019 table, reflecting inflation, newer cost data, and 2018 tax changes, plus a higher self-sufficiency reserve ($15,764).

When does child support end in Ohio?

Generally at 18, but it can continue while the child is still in high school full-time, and longer for a child with a disability. The exact end date is stated in the order.

How do I lower or change my Ohio child support order?

You request a review and modification through your county CSEA or the court, generally based on a substantial change in circumstances. A court can also deviate from the guideline for the factors listed in R.C. 3119.23.

Is this an official Ohio child support calculation?

No. It's an educational estimate using the state's guideline method. The binding amount is set by a court or CSEA on the official worksheet, and a judge may deviate. Use the official ODJFS calculator or consult a professional for a definitive figure.
