Ohio child support begins with the state’s guideline schedule and applicable worksheet, using financial information about both parents and the children covered by the order. It is not a flat percentage of one parent’s take-home pay. Parenting time, childcare, health coverage, and other permitted adjustments can affect the result.
Use the official Ohio Child Support Calculator for an estimate, not a privately invented formula. The state warns that its result is an estimate, not a support order. A court or Child Support Enforcement Agency determines the obligation through the appropriate legal process.
Gather inputs before opening the estimator
The calculator asks about the parenting arrangement, children covered, income, and adjustments. Have supporting documents available rather than entering approximate numbers as if they were verified. Important information includes:
- Both parents’ gross annual income from employment and other relevant sources.
- Overtime, bonuses, and commissions for the relevant prior years.
- Self-employment receipts and documentation of allowable business expenses.
- Other children each parent has a legal duty to support and relevant existing orders.
- Court-ordered spousal support actually paid and other relevant support information.
- Employment-related childcare expenses, including subsidies or reimbursements.
- The actual health-insurance premium information required for the children covered by the order.
- The court-ordered parenting-time arrangement and any existing deviations.
Revised Code 3119.05 requires verification of current and past earnings using suitable records or electronic means. It also supplies specific treatment for variable income, other children, childcare, and other items. Taxable income, business cash flow, and income used for support are not automatically the same figure.
Do not assume that unemployment means zero income will be used. Imputation involves legal standards and statutory protections, including circumstances involving disability, documented job-search efforts, and incarceration. An individual assessment is needed rather than a guess about what a parent could earn.
Understand childcare and medical support
The statutory childcare calculation concerns verified costs necessary for work or employment training, subject to limits and adjustments. Subsidized or reimbursed costs and applicable childcare tax credits affect the amount used. Simply entering the daycare’s advertised annual price can misstate the parent’s actual qualifying expense.
Health coverage and cash medical support also matter. Keep the insurance documentation that identifies the actual premium cost and covered people, and follow the estimator’s specific questions. Do not treat the entire family premium or every out-of-pocket medical bill as an interchangeable deduction. Extraordinary medical expenses may be addressed through a separate order under section 3119.05(F).
How do overnights affect support?
Section 3119.051 generally requires a 10 percent reduction in the annual individual support obligation when the court-ordered parenting time equals or exceeds 90 overnights per year. This is an adjustment within the calculation, not permission to reduce an existing monthly payment yourself. A court may eliminate a previously granted adjustment at the obligee’s request when the obligor has failed to exercise ordered time without just cause.
Under section 3119.231, more than 90 ordered overnights also requires the court to consider an additional deviation. At 147 or more ordered overnights, a court declining that deviation must state the factual basis. Neither provision guarantees a particular additional reduction or zero support for equal parenting time.
A deviation needs more than a preferred number
Section 3119.22 permits a court to deviate when the guideline result would be unjust or inappropriate and therefore not in the child’s best interests, with required findings. Section 3119.23 lists considerations such as unusual needs, extraordinary parenting-time travel costs, financial resources, and significant in-kind contributions.
A deviation is not an unrestricted personal discount. Identify the supporting facts and the court’s findings in any existing order. Do not enter a desired deviation in the estimator and describe the resulting figure as the amount Ohio law requires.
A hypothetical input example, not a support quote
Suppose two parents have one child, employment income of $64,000 and $42,000, documented employment-related childcare expenses, and a parenting-time order specifying 120 annual overnights for the paying parent. Those facts identify inputs to investigate; they do not establish a monthly obligation.
The estimate still depends on variable income, qualifying expense amounts, insurance, other support responsibilities, and any deviation. Enter verified figures in the official estimator and retain the worksheet and assumptions. The calculator also states that it cannot be used when combined annual gross income exceeds $336,000; cases outside its scope need separate analysis.
An estimate does not amend an existing order. See the support modification guide for that process. For representation information, review the firm’s custody and support services and Dean Hines’s profile.
