Our Ohio child support calculator applies the income-shares structure used with Ohio’s guideline worksheets: combine parents’ gross incomes (simplified here), determine a basic monthly child support obligation from an illustrative schedule with interpolation between income points, then allocate that obligation using each parent’s percentage of combined income. The non-custodial parent’s estimated payment is their pro-rata share of the basic obligation. Review other family-law calculators for multi-state comparisons.
Basic obligation = Schedule lookup(combined gross income, # children)NCP payment = Basic obligation × (NCP income ÷ combined income)Combined income is compared to schedule points up to $35,000.00 per month in this tool; higher incomes extrapolate from the top segment.
Ohio guideline income shares + base support (conceptual)
Illustrative result: basic two-child obligation ≈ $1,608.59; NCP payment ≈ $965.15 (before worksheet adjustments).
Same $10,000 combined gross: select one child in the calculator for a lower base obligation and proportional payment.
