Example Child Support Calculation in Ohio
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined monthly income: $5,000 + $3,000 = $8,000
Step 2: Parent A's income share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation from the guidelines schedule for $8,000 combined income and 2 children.
Step 4: Multiply the basic obligation by Parent A's share (62.5%) to determine their payment.
Note: Additional adjustments for health insurance, child care, and parenting time may apply.
