Ohio Child Support Calculator 2026 – ORC 3119 Income Shares Guidelines
Use our free ohio child support calculator for 2026 to estimate guideline support under Ohio Revised Code Chapter 3119. This official ohio child support calculator uses Income Shares model. Therefore, the court combines both parents’ annual gross incomes and consults the Basic Child Support Schedule ORC 3119.021. For example, the schedule covers $8,400 to $300,000 per year in $600 increments for one through six or more children. In addition, Ohio provides parenting time adjustments and self-sufficiency reserve for low income. As a result, our Ohio child support calculator gives you an accurate 2026 estimate in seconds.

How Ohio Child Support Is Calculated in 2026:
Ohio calculation has five steps when you use the ohio child support calculator. First, determine gross annual income. Second, calculate combined gross. Third, lookup basic obligation from schedule. Fourth, allocate proportionally. Fifth, apply parenting time and add-ons. Because of this process, the ohio child support calculator reflects income shares and time. In addition, courts protect low income with reserve.
Step 1 - Determine Annual Gross Income
Under ORC 3119.01, gross income includes wages, salaries, overtime, bonuses, commissions, self-employment income, rental and investment income, Social Security benefits including disability, workers compensation, unemployment benefits, pensions, spousal support received, royalties, trust income, and military pay including base pay and allowances. However, benefits from means-tested programs Ohio Works First, SNAP, SSI, disability financial assistance are excluded. Mandatory wage deductions like union dues also excluded, though taxes not deductible. Therefore, gross is broad but excludes public assistance. In addition, court averages gross over at least six months to smooth fluctuations.

Step 2 - Apply Basic Child Support Schedule ORC 3119.021 $8,400-$300,000
The ohio child support calculator uses Basic Child Support Schedule ORC 3119.021 that covers combined annual incomes from $8,400 to $300,000 per year, in $600 increments, for one through six or more children. For example, at $50,000 combined, one child about $7,200 annual, two children about $10,800 using the ohio child support calculator. At $150,000 combined, one child $15,000 annual, two $22,500. As income rises, basic obligation increases. Therefore, combined income directly drives base amount. In addition, if combined exceeds $300,000, ORC 3119.04 does not extend schedule upward. Instead, court sets obligation case-by-case considering needs and standard of living. However, statute sets floor: basic combined obligation must be no less than amount computed for $300,000, unless court determines unjust and enters findings.

Step 3 - Allocate Proportionally and Self-Sufficiency Reserve
Each parent's percentage equals their income divided by combined gross income when using the ohio child support calculator. For instance, if Parent 1 earns $60k of $100k combined (60%), Parent 1 responsible for 60% of basic obligation. Custodial parent's share assumed spent directly, non-custodial pays share to custodial. However, Ohio protects low income via self-sufficiency reserve per ORC 3119.021. Reserve is 116% of federal poverty level for single person. Parents below threshold pay reduced support using sliding scale multiplier times (guideline income - $8,400) plus annual minimum support per ORC 3119.06. Therefore, paying parent retains enough for basic living needs. In addition, minimum $50 per month per 3119.06 required even with low income. Compare with Florida child support calculator that uses $10k schedule and gross-up, and New York child support calculator with $193k cap.
Step 4 - Apply Parenting Time Adjustments 90+ and 147+ Nights
Ohio provides automatic adjustments based on parenting time non-custodial exercises when using the ohio child support calculator. First, 90 or more overnights per year: annual obligation automatically reduced by 10% per ORC 3119.051(A). Second, court may eliminate previously granted 10% adjustment at obligee's request if obligor without just cause failed to exercise court-ordered parenting time per 3119.051(B). Third, more than 90 overnights: court shall consider whether to grant additional deviation under ORC 3119.22 for extended parenting time factor listed at ORC 3119.23(C) per 3119.231(A). Granting deviation is discretionary, but considering is not, and comes in addition to 10% adjustment. Therefore, 90+ triggers auto 10%, over 90 triggers duty to consider extra. Finally, 147 or more overnights: if court does not grant that deviation, it must specify in order facts basis per ORC 3119.231(B). As a result, 147+ is significant threshold requiring findings if deviation denied. Use our Pennsylvania child support calculator to see 40% custody reduction comparison.
Step 5 - Add-Ons and HB 338 2025 Update
Basic schedule covers ordinary living costs, but health insurance premiums covering children, childcare including daycare, and ordinary medical expenses split proportionally in the ohio child support calculator. In addition, House Bill 338 effective March 20, 2025 amends ORC 3119.86 to allow courts to issue new child support orders for disabled children over 18 for first time. Before change, courts could only continue existing order past 18. If parents divorced after child already turned 18, many counties refused to establish new order. HB 338 resolves statewide, ensuring parents share responsibility for disabled adult child regardless when proceedings began. Therefore, law did not change calculation, but allows new orders for disabled adults. For official Ohio tools, see ODJFS Official Calculator at https://jfs.ohio.gov/support
Ohio Child Support Example
Suppose Parent 1 annual gross $55,000 and Parent 2 $40,000. Combined $95,000. For 2 children, basic annual about $16,800 using ohio child support calculator. Parent 1 share 57.9% = $9,727, Parent 2 share 42.1% = $7,073. Standard without parenting adjustment, Parent 1 pays $9,727 annual or $810 monthly to Parent 2 if Parent 2 custodial plus childcare $6,000 x 57.9% = $3,474 total $13,201 annual or $1,100 monthly. However, if Parent 1 has 90+ overnights, 10% reduction: $9,727 x 0.9 = $8,754 annual or $729 monthly plus add-ons reduced. If 147+ overnights, court shall consider additional deviation beyond 10%. As a result, parenting time reduces obligation calculated by ohio child support calculator.
