How Child Support Is Calculated in Ohio
Factors That Affect Child Support in Ohio
Technical details and legal basis
Ohio uses the Income Shares model (Ohio Revised Code § 3119) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.
Important Notes for Ohio
- • Ohio uses the Income Shares model, combining both parents' gross incomes to determine the total child support obligation.
- • Each parent's share is proportional to their percentage of the combined income.
- • Ohio adjusts the basic obligation for work-related child care costs, health insurance premiums for the children, and extraordinary medical expenses.
- • A parenting time adjustment may apply when the non-custodial parent has the children for more than 90 overnights per year (approximately 25% of the time).
Example Calculation
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined income: $8,000
Step 2: Parent A's share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation for $8,000 combined and 2 children.
Step 4: Multiply by Parent A's share (62.5%).
Adjustments for health insurance, child care, and parenting time may apply.
