Ohio Child Support Calculator

Ohio uses the income shares model under Ohio Revised Code 3119. Both parents' annual gross incomes are combined to look up a basic child support obligation from the statutory schedule. That obligation is then divided proportionally based on each parent's share of the combined income. Additional costs such as childcare and health insurance are added before the split. The obligor (non-residential parent) pays their share to the custodial parent.

Gross income in Ohio includes all earned and unearned income from any source. This covers wages, salaries, overtime, bonuses, commissions, self-employment income, rental income, royalties, severance pay, pensions, retirement benefits, annuities, Social Security, disability benefits, workers' compensation, unemployment benefits, interest, dividends, and trust income. Ohio also allows the court to impute income if a parent is voluntarily unemployed or underemployed.

Ohio recognizes extended parenting time when the non-residential parent has the child for 90 or more overnight stays per year (approximately 25% of the time). Under Ohio R.C. 3119.051, courts commonly apply a 10% deviation to reduce the support obligation when extended parenting time is ordered. For shared parenting (146+ overnights, approximately 40%+), a more significant adjustment may apply.

Yes, either parent can request a review and modification of the child support order. Ohio allows modification when there is a change in circumstances that results in a 10% or greater difference between the current order and the recalculated guideline amount. Common reasons include significant changes in income, job loss, changes in custody or parenting time, changes in childcare or medical costs, or a child aging out of the order.

In Ohio, child support generally continues until the child turns 18. If the child is still attending high school at age 18, support continues until the child turns 19 or completes high school, whichever comes first. Support may also continue for a child who is mentally or physically disabled and unable to support themselves. Ohio courts do not typically order parents to pay for college tuition as part of the child support order.

Yes. Under Ohio R.C. 3119.05, work-related childcare expenses and the cost of health insurance for the child are added to the basic child support obligation before it is divided between the parents. Each parent pays their proportional share of these additional costs based on their share of the combined gross income.

This calculator provides an estimate based on the Ohio child support guidelines. Actual court-ordered support may differ because Ohio judges have discretion to deviate from the guidelines based on factors listed in Ohio R.C. 3119.23, including the special needs of the child, the obligor's other court-ordered support obligations, extended parenting time, the standard of living the child would have enjoyed had the marriage continued, and other relevant factors.
