Note
This is NOT legal advice and NOT a statement of any law. It is generic arithmetic: it applies the displayed formula to the figures you entered, and every rate, fraction, factor, cap and threshold shown is a value YOU supply, not a statutory or court-approved figure. No jurisdiction's rule is built in. Real entitlements, fees, interest, support amounts and deadlines depend entirely on the jurisdiction, the wording of the contract, the day-count and rounding conventions the court applies, and the facts of the case. Use these figures only as a rough arithmetic check and consult a qualified lawyer in the relevant jurisdiction before relying on any number.

How is the duration of spousal support typically determined?+
Many jurisdictions use a formula tied to the length of the marriage, such as a fraction (for example, half the length of a marriage of moderate length), while long marriages may result in indefinite or open-ended support. The calculator applies a common ratio-based estimate to give you a starting reference point.
Does a longer marriage always mean longer support?+
Generally yes, longer marriages tend to produce longer support durations, and many jurisdictions treat marriages above a certain length threshold (often 15-20 years) as eligible for indefinite support rather than a fixed term. Short marriages typically result in shorter or no support obligation.
Can spousal support duration be modified after it's set?+
Often yes — many orders allow modification if there's a significant change in circumstances, such as job loss, retirement, or remarriage of the recipient, though rules vary widely by jurisdiction. This calculator only estimates an initial duration, not modification scenarios.
Why did my result differ from what I've heard about similar cases?+
Spousal support duration also depends on factors this simple calculator doesn't capture, such as each spouse's earning capacity, age, health, and the standard of living during the marriage. Treat the output as a rough guideline, not a court-guaranteed figure.
Is this the same calculation as spousal support amount?+
No, this calculator estimates only the duration (how long support lasts), not the dollar amount, which typically depends on income differences between spouses and is calculated separately. This is general information, not legal advice — consult a family law professional for your jurisdiction.
