How Ohio calculates child support
Ohio's child support guidelines are established by Ohio Rev. Code § 3119.021. The state uses an Income Shares model, which combines both parents’ incomes and allocates the basic support obligation between them in proportion to each parent’s share of the combined income.
This calculator applies the current guideline edition: ODJFS schedule JFS 07767 (rev. 6/2023).
The result is the presumptive guideline amount — the starting point a Ohio court uses before considering deviation factors. The court-ready worksheet with the full line-by-line calculation, guideline-edition badge, and statutory citation is available in Aequis with a free 14-day trial.
Ohio child support FAQ
How is child support calculated in Ohio?
Ohio sets child support under its official guidelines (Ohio Rev. Code § 3119.021), which use a income shares approach. The guideline produces a presumptive monthly amount from the parents' incomes, the number of children, and inputs such as parenting time, childcare, and health insurance costs.
Is this the exact amount a Ohio court will order?
No. This is an informational estimate of the presumptive guideline amount. Courts can deviate based on statutory factors, and official worksheets may require inputs this calculator does not collect. Always verify against the official guidelines worksheet before relying on any number.
What income counts for child support in Ohio?
Guidelines generally start from each parent's gross income from most sources, with state-specific definitions, exclusions, and deductions. This calculator uses gross monthly income; consult Ohio Rev. Code § 3119.021 for what your state includes.
Do overnights affect child support in Ohio?
Many states adjust the obligation for parenting time once overnights pass a threshold, and this calculator applies Ohio's guideline treatment of overnights where the guideline provides one. The exact effect depends on the state's formula and the parents' incomes.
