There is no published average child support in Ohio, and any figure claiming to be one would mislead you. Ohio runs every case through an Income Shares formula that pulls in both parents’ incomes, the number of children, parenting time, and health insurance costs, then produces a specific dollar amount for that family. Orders can be as low as $80 a month at the bottom of the schedule and rise into court-discretion territory once combined parental income passes $336,467 a year.1Ohio Legislative Service Commission. Ohio Revised Code 3119.021 – Basic Child Support Schedule What matters is the formula, because that is what will determine your number.
How the Ohio Formula Works
Ohio uses what’s called the Income Shares Model. The idea behind it is simple: a child should get roughly the same share of parental income they would have received if the parents stayed in one household. Both parents’ incomes go into the worksheet, the state’s schedule assigns a combined annual obligation based on that total, and the obligation is then split between the parents in proportion to what each one earns.2Ohio Department of Job and Family Services. Child Support Guideline Manual
An example makes it concrete. If Parent A earns $45,000 and Parent B earns $15,000, combined income is $60,000. Parent A carries 75% of that combined figure and Parent B carries 25%. Whatever total obligation the schedule produces for their number of children, Parent A owes 75% of it and Parent B owes 25%. The parent with less parenting time generally pays their share to the other parent, on the theory that the parent with the child most of the time is already spending their share directly.
The governing statutes sit in Chapter 3119 of the Ohio Revised Code. Section 3119.021 holds the schedule and Section 3119.022 sets the worksheet.3Ohio Legislative Service Commission. Ohio Revised Code Chapter 3119 – Calculation of Child Support Obligation The same tables apply whether your order comes out of a domestic relations court or an administrative hearing at the Child Support Enforcement Agency.
What Counts as Income
Ohio defines gross income broadly. Wages, salaries, overtime, bonuses, commissions, self-employment profits, workers’ compensation, unemployment benefits, disability payments, and retirement income all count.4Ohio Legislative Service Commission. Ohio Revised Code 3119.01 – Calculation of Child Support Obligation Definitions The state’s calculator asks for three years of income so a good year or bad year doesn’t skew the order.5Ohio Child Support Calculator.

Overtime and bonuses have their own rule. The court uses the lesser of two figures: the three-year average of overtime, commissions, and bonuses, or the total from the most recent year alone.6Ohio Legislative Service Commission. Ohio Revised Code 3119.05 – Determination of Gross Income That blocks a one-time windfall from inflating the number and also blocks a parent from throttling their overtime to lower it.
Before the schedule is applied, each parent’s gross income is adjusted down for support already being paid for other children, court-ordered spousal support, local income taxes, and mandatory work-related costs like union dues. The result, the adjusted gross income, is the figure that actually drives the calculation.
When Courts Impute Income
If a court decides a parent is voluntarily unemployed or underemployed, it will assign them a “potential income” based on what they could reasonably earn. The statute lists factors the court weighs, including work history, education, local job market conditions, physical or mental limitations, special skills or training, and any felony conviction affecting employability. Courts can also impute income to idle assets using the local passbook savings rate.4Ohio Legislative Service Commission. Ohio Revised Code 3119.01 – Calculation of Child Support Obligation Definitions
An involuntary layoff with a genuine job search rarely triggers imputation. Walking away from a $70,000 job to freelance at $30,000 without a good reason usually does.
The Floor, the Ceiling, and the Reserve
The schedule maintained by the Ohio Department of Job and Family Services lists combined annual parental income in $600 steps, starting at $8,400. Six additional columns give the total annual obligation for one through six children at each income level. More children mean a higher total obligation, but the amount added per child shrinks as the family size grows.1Ohio Legislative Service Commission. Ohio Revised Code 3119.021 – Basic Child Support Schedule
At the top, the schedule stops at $336,467 of combined income. Above that, the court applies the schedule up to the cap and then uses its discretion for the rest, with the total never falling below what the maximum-schedule figure would produce.7Ohio Legislative Service Commission. Ohio Revised Code 3119.04 – Determination of Support Obligation Where Combined Gross Income Is Greater Than or Less Than Amounts Covered by Schedule At the bottom, combined income under $8,400 produces a minimum order of $80 per month.8Ohio Legislative Service Commission. Ohio Revised Code 3119.06 – Minimum Child Support Order
Between the floor and the standard schedule, Ohio also builds in a self-sufficiency reserve. It’s pegged to 116% of the federal poverty level for one person. If the paying parent’s income lands in that band, the schedule phases the obligation in gradually rather than imposing the full guideline amount and pushing the parent into poverty.1Ohio Legislative Service Commission. Ohio Revised Code 3119.021 – Basic Child Support Schedule
Health Insurance and Cash Medical Support
Every Ohio child support order has to deal with health coverage. When a parent carries the child on an employer or private plan, the out-of-pocket premium for that coverage is credited against that parent’s income on the worksheet. The credit is the actual premium minus any subsidy, such as a premium tax credit.9Ohio Legislative Service Commission. Ohio Revised Code 3119.30 – Determining Person Responsible for Health Care of Children
On top of that, every order includes a cash medical support amount for routine out-of-pocket costs like co-pays and prescriptions. The amount depends on the number of children and is split between the parents using their income share percentages.4Ohio Legislative Service Commission. Ohio Revised Code 3119.01 – Calculation of Child Support Obligation Definitions The specific dollar figure comes from administrative rules, so it depends on when the order was issued.
Shared Parenting and Other Deviations
When a court-ordered parenting plan gives each parent at least 90 overnights per year, the paying parent’s annual obligation drops by 10%.10Ohio Legislative Service Commission. Ohio Revised Code 3119.051 – Reduction of Annual Individual Support Obligation That credit is automatic once the overnight threshold is met.
Courts can also move further from the guideline number under the broader deviation statute if applying it as written would be unjust or contrary to the child’s best interest, but they must put the reasons in writing.11Ohio Legislative Service Commission. Ohio Revised Code 3119.24 – Shared Parenting Order Child Support Provisions Section 3119.23 lists the recognized deviation factors, which include:
- Special physical, psychological, or educational needs of the child
- Extraordinary parenting-time travel costs
- Significant disparity in the standard of living between the two households
- Benefits from remarriage, where a new partner absorbs part of a parent’s living expenses
- In-kind contributions such as directly paying for lessons, sports gear, or clothing outside the order
- A parent paying post-secondary education costs
The statute closes with a catch-all for “any other relevant factor.”12Ohio Legislative Service Commission. Ohio Revised Code 3119.23 – Deviation Factors In practice, deviations that stick are the ones tied to documented, ongoing expenses. A one-time cost almost never justifies a permanent change.
The 2% Processing Fee
Ohio adds a 2% administrative processing charge on top of every support payment, paid by the obligor to cover routing payments through the Child Support Enforcement Agency.13Ohio Department of Job and Family Services. Frequently Asked Questions On a $500 monthly order that’s an extra $10. Small, but it’s real money coming out of the paycheck and easy to leave out when you’re estimating what you’ll actually pay.
How Long the Obligation Lasts
Ohio child support generally ends at 18. It continues past that birthday in only three situations: the child is still enrolled full-time in an accredited high school, the child has a mental or physical disability that keeps them from becoming self-supporting, or the parents agreed in a separation or divorce agreement to keep support running. Ohio does not require a parent to pay through college unless they voluntarily agreed to.14Ohio Legislative Service Commission. Ohio Revised Code 3119.86 – Duty of Support Beyond Eighteenth Birthday
When Circumstances Change
Either parent can ask a court to recalculate at any time. If the number the current schedule and worksheet produce differs from the existing order by more than 10% in either direction, that gap alone justifies modification.15Ohio Legislative Service Commission. Ohio Revised Code 3119.79 – Modification of Child Support Smaller changes can still qualify if there’s been a substantial change of circumstances that wasn’t anticipated when the original order was set, such as a job loss, a serious medical condition, or the birth of another child. Inadequate health insurance for the child is grounds for modification on its own.
One point worth internalizing: modifications aren’t retroactive. The new amount runs from the date the motion is filed, not from when your income actually changed. If your circumstances shift, filing quickly is what protects you.
Getting a Realistic Estimate
Ohio runs a free calculator at ohiochildsupportcalculator.ohio.gov. Plug in both parents’ income figures from the last three years, the number of children, any existing support obligations, health insurance premiums for the child, and work-related childcare costs, and it will produce a guideline number close to what a court would order.5Ohio Child Support Calculator. Ohio Child Support Calculator It won’t capture every deviation a judge might apply, but it’s the honest answer to “how much will I pay?” in a way that a statewide average never could be.
