This tool estimates Ohio spousal support based on the six highest-weight inputs under ORC 3105.18. The income fields drive the base monthly estimate — Ohio courts most commonly look at the income gap between spouses as the primary driver for both amount and duration. The remaining factors (marriage length, age, standard of living, assets, and career sacrifice) adjust the estimate up or down and heavily influence duration.
Unlike child support, Ohio has no statutory formula for alimony. ORC 3105.18(C)(1) lists 14 factors, and judges have wide discretion. The ranges in this calculator reflect commonly observed patterns from Ohio court outcomes, not a formula. Your actual result will depend on your judge, your county, and how your specific facts are presented.
| ORC 3105.18 Factor | How courts typically weight it | Impact on this estimate |
|---|---|---|
| §(C)(1)(a) — Income & earning ability | Primary driver. Courts look at both gross income and realistic earning potential. | Monthly amount is set as ~15–25% of the income gap |
| §(C)(1)(b)(c) — Age & physical/mental condition | Older spouse with limited re-entry path gets longer duration. | Duration multiplier ×1.0–×1.6 |
| §(C)(1)(d) — Standard of living | Courts try to avoid dramatic disparity in post-divorce lifestyle. | Amount modifier +0–+20% |
| §(C)(1)(e) — Marriage duration | Strongest single factor for duration. Long marriages = longer support, possibly indefinite. | Duration base: 15–25% of marriage length for mid-range; indefinite for 20+ yr marriages with large gaps |
| §(C)(1)(f)(g) — Assets & retirement | If lower-earning spouse receives substantial assets in division, support is often reduced. | Amount modifier −10–+10% |
| §(C)(1)(h) — Education & earning ability | Career sacrifice (staying home, deferring education) increases support and duration. | Duration multiplier ×1.0–×1.5; amount +10–+25% |
Ohio courts set two numbers: how much per month and for how long. Amount is primarily about maintaining a reasonable standard of living relative to the income gap. Duration is primarily about how long it will take the supported spouse to become self-sufficient — which depends heavily on their age, career history, and the length of the marriage.
Spousal support is rarely awarded in short marriages unless the lower-earning spouse gave up a career or education to support the other's. When awarded, duration typically equals the marriage length or less. Amounts tend to be modest — enough to cover a transition period, not a long-term lifestyle subsidy.
This is the most common range where alimony is contested. Courts typically award support for 20–40% of the marriage duration. A 10-year marriage might produce 2–4 years of support. Amounts are based on the income gap, often targeting 40–50% of the combined income for the lower earner post-divorce (before child support).
Long-marriage alimony is the most substantial. Support durations of 7–10+ years are common. When one spouse was a primary homemaker for a 20+ year marriage and is over 55, Ohio courts often award indefinite support, terminable only on remarriage, death, or a substantial change in circumstances. The 14-factor analysis under ORC 3105.18 tilts heavily toward duration in these cases.

Note: Ohio revised the numbering in ORC 3105.18 — you may see different factor numbers in older case citations. The factors are substantively the same.
Ohio courts determine spousal support under ORC 3105.18 by weighing 14 statutory factors including each spouse's income and earning ability, the duration of the marriage, the standard of living during marriage, education levels, ages and physical condition of each spouse, retirement benefits, and tax consequences. There is no formula — judges have broad discretion to set amount and duration based on these factors.
No. Unlike child support, Ohio has no statutory formula for spousal support. ORC 3105.18 lists 14 factors courts must consider, but the weight given to each factor is at the judge's discretion. Some counties have informal guidelines that local practitioners know, but these are not public and are not binding. This calculator uses commonly observed patterns from Ohio case outcomes to produce ranges, not guaranteed amounts.
Duration depends heavily on marriage length. Short marriages (under 5 years) rarely produce long-term support. Mid-length marriages (5–15 years) typically produce support for 20–40% of the marriage duration. Marriages over 20 years, especially with a stay-at-home spouse, may produce indefinite support or support lasting until remarriage or significant income change. Ohio courts can order a review date or make support modifiable on change of circumstances.
Yes, if the original order allows for modification. Under ORC 3105.18(E), an Ohio court can modify spousal support upon a change in circumstances, including job loss, significant income change, cohabitation, or remarriage of the recipient — but only if the decree reserves jurisdiction to modify. If the order is non-modifiable, neither party can seek changes regardless of circumstance. Always negotiate modifiability language during settlement — it matters enormously post-decree.
Ohio is a no-fault divorce state for property division purposes. Marital fault (adultery, abandonment) is generally not a standalone factor in alimony. However, ORC 3105.18 includes "any other relevant factor" as a catch-all, and some Ohio judges may consider conduct that dissipated marital assets when setting support. Direct fault claims rarely drive alimony outcomes, but they can affect credibility and negotiations.
For divorce decrees finalized after December 31, 2018, the Tax Cuts and Jobs Act eliminated the federal deduction for alimony paid and the inclusion requirement for alimony received. Alimony is no longer deductible by the payor or taxable income to the recipient for federal purposes. Ohio follows federal treatment for income tax purposes. This significantly changed the economics of alimony negotiations — the old "gross-up" calculations no longer apply for post-2018 decrees.
