Child Support in Ohio: How It's Calculated, Modified & Enforced
A plain-English guide to Ohio child support — the guideline model, how the number is computed, the modification and enforcement process, and where to find the official worksheet.
Direct answer
The statutory minimum is $80/month for all children (courts may go lower only in limited cases such as verified disability or incarceration).
Ohio uses the Income Shares Model on COMBINED gross income, with the basic obligation read from the Basic Child Support Schedule (JFS 07767, R.C. 3119.021). The schedule spans $8,400-$336,000 combined annual income; below that the minimum is $80/month, and above it the court extrapolates. A 90-overnight parenting-time credit cuts the obligation 10%, and a Self-Sufficiency Reserve is embedded. (Schedule numbers not machine-extracted; see note.)

How a support order is established in Ohio
Determine each parent\'s annual gross income (wages, bonuses, business, benefits, etc.).
Apply adjustments (spousal support paid, credit for other children, half of self-employment tax).
Combine adjusted gross incomes and locate the Basic Child Support Obligation on the JFS 07767 schedule.
Apply the 90-overnight parenting-time credit (10% reduction) if qualifying.
Add the child\'s health insurance and childcare costs, split by income share using Worksheet JFS 07768/07769.
The obligor pays their proportional share; cash medical support is computed separately.
Worked examples
Illustrative example - combined $100,000/yr, 1 child, 60% obligor — Combined adjusted gross income $100,000/year; one child. Published schedule amount for this income is about $11,864/year. Obligor earns 60%, so pays 60% x $11,864 = $7,118/year (~$593/month). With 90+ overnights the 10% parenting-time credit would lower it to about $534/month before add-ons. Ohio\'s schedule gives the total basic obligation; the paying parent covers only their income-share percentage, reduced by parenting-time credits.
Modifying or enforcing an order
Orders in Ohio can be modified when there is a substantial change in income, custody, or circumstances. Use the modification eligibility check and the cross-state comparison tool to see how a move would change the outcome. Enforcement runs through the state agency and can include income withholding and contempt proceedings.

What is Ohio\'s minimum child support?
The statutory minimum is $80/month for all children (courts may go lower only in limited cases such as verified disability or incarceration).
Does a 50/50 custody arrangement change the amount?
A 90-overnight-or-more parenting-time order triggers a 10% reduction; more equal splits may use the shared-parenting worksheet.
