Ohio Spousal Support Calculator 2026

Ohio law calls it spousal support, and it has no formula behind it. A judge weighs 14 statutory factors and awards what is appropriate and reasonable. This page shows you those factors instead of inventing a number.

What Ohio courts weigh instead of a formula

OH sets alimony by judicial discretion; there is no statutory formula. Courts weigh the enumerated factors below.

Factors the court weighs

Income of the parties, from all sources
Relative earning abilities of the parties
Ages and the physical, mental, and emotional conditions of the parties
Retirement benefits of the parties
Duration of the marriage
Extent to which it would be inappropriate for a custodial party to seek employment outside the home
Standard of living of the parties established during the marriage
Relative extent of education of the parties
Relative assets and liabilities of the parties
Contribution of each party to the education, training, or earning ability of the other party
Time and expense necessary for the spouse seeking support to acquire education, training, or job experience
Tax consequences, for each party, of an award of spousal support
Lost income production capacity of either party that resulted from that party marital responsibilities
Any other factor that the court expressly finds to be relevant and equitable

ORC 3105.18(C)(1)(a)-(n) (14 enumerated factors)

Assumptions

This tool does not estimate a dollar amount for discretionary states: any number would be invented.
No statutory amount or duration formula; local county "rules of thumb" are unofficial. Uniform Domestic Relations Form 14 records the 3105.18 findings in decrees.

Estimate only. The court or state agency calculation controls.

Ohio alimony under ORC 3105.18(C)(1) (spousal support factors).

How Ohio decides spousal support without a formula

Start with the name. Since the early 1990s Ohio statutes have used spousal support, not alimony, for payments from one spouse to the other for sustenance. If you search Ohio court papers for alimony, spousal support is the term you actually need.

The controlling statute is ORC 3105.18. It gives the court two questions: whether spousal support is appropriate and reasonable, and if so, in what amount and for how long. To answer, section (C)(1) lists 14 factors the court must consider, lettered (a) through (n). Nothing in the statute multiplies incomes, sets percentages, or ties years of support to years of marriage.

The factors cover the financial picture and the marriage itself: each spouse income and earning ability, ages and health, retirement benefits, how long the marriage lasted, whether a custodial parent should be expected to work outside the home, the standard of living during the marriage, education, assets and debts, what each spouse contributed to the other education or earning power, the cost of retraining, tax consequences, income lost to marital responsibilities, and a catch-all for anything else the court finds relevant and equitable.

Because the list ends in a catch-all and the standard is equity, two Ohio counties can reach different numbers on similar facts. Some counties are known for informal rules of thumb, but none of them appear in the statute, and no court is bound by them. The findings that matter are the ones the decree records against the 3105.18 factors, which the Supreme Court of Ohio uniform domestic relations forms are built to capture.

How to use this page

Use the panel above as a preparation checklist rather than a calculator. It lists the 14 factors an Ohio judge must consider, so you can gather evidence for each one that touches your marriage: income records, earning history, health, retirement statements, and what the household standard of living actually cost.

Be careful with any site that prints an Ohio spousal support number. With no formula in the statute, such numbers come from a county rule of thumb, another state, or thin air, and the judge deciding your case is bound by none of them.

Duration is discretionary too. Ohio publishes no schedule tying support years to marriage years; the length of the marriage is one factor among the 14. Courts can also retain jurisdiction to modify support later, but only if the decree says so.

Note that spousal support interacts with child support: court-ordered spousal support a parent actually pays is deducted from that parent income in the child support worksheet, so the two orders are usually decided together.

Ohio spousal support FAQs

How is spousal support calculated in Ohio?

It is not calculated; it is decided. ORC 3105.18(C)(1) directs the judge to weigh 14 factors, from incomes and earning abilities to the standard of living and tax consequences, and award what is appropriate and reasonable. The statute contains no percentage, no chart, and no duration table.

Is alimony the same thing as spousal support in Ohio?

Yes. Ohio replaced the term alimony with spousal support in its statutes, and modern decrees use the newer term. The concept is the same: payments for the sustenance and support of a former spouse, separate from property division and from child support.

Is there a rule of thumb for Ohio spousal support amounts?

Local ones exist, and none are law. Some counties are informally known for patterns like a year of support per so many years of marriage, but the statute never says that, and a judge who followed a rule of thumb without weighing the 14 factors would be skipping the required analysis. Treat any pattern as a rumor about tendencies, not a rule.

How long does Ohio spousal support last?

As long as the decree says. Duration comes out of the same 14-factor weighing as the amount, with the length of the marriage as one input. Support can be indefinite in long marriages, and it ends per the decree terms; modification later is possible only when the decree reserved jurisdiction and circumstances changed.

Does misconduct change Ohio spousal support?

Not through a listed factor. Unlike some states, the ORC 3105.18(C)(1) list does not name marital fault, and Ohio decides support on the enumerated considerations plus the catch-all. Conduct can still surface indirectly, for example through economic effects a court finds relevant and equitable.

Why does this site compute child support for Ohio but not spousal support?

Because the law differs. Ohio child support runs on a published schedule and statutes with real arithmetic in them, so a calculator can be honest there. Ohio spousal support runs on judicial discretion over 14 factors. Printing a number would misstate the very statute this page cites.

Good to know in Ohio

Spousal support paid under a court order is deducted from the payer income in the Ohio child support calculation (ORC 3119.05(B)), one concrete way the two awards connect.
Ohio divides marital property first under ORC 3105.171 and considers spousal support after that division, so the property outcome shapes the support question.
