Spousal Support Duration Calculator

Estimate how long spousal support might last under the SSAG without-child-support formula, and check whether the “rule of 65” applies to your marriage.

Estimate only — not legal advice. Assumes entitlement is established and no dependent children are involved.

📏

0.5–1 Year Per Year

The standard SSAG duration range, before any indefinite-duration exception applies.

🔢

The Rule of 65

Years married plus the recipient's age at separation ≥ 65 (for marriages of 5+ years) triggers indefinite duration.

📅

20-Year Marriages

Any marriage of 20 years or more triggers indefinite duration automatically, regardless of age.

🔄

Indefinite ≠ Forever

Indefinite support can still be varied or reviewed as circumstances genuinely change.
