Estimate spousal support and how long it lasts. Most states decide alimony by judicial discretion rather than a formula, so each calculator below is built on that state's actual statute — producing a guideline number where the law provides one, and the factors a judge weighs where it does not.
Child support is set by a statewide formula in every state, but alimony is different. Only a handful of states — including Illinois, Colorado, New York, Pennsylvania, Massachusetts, and (as a strict cap) Texas — publish guideline math for the amount of spousal support. In the rest, judges decide both the amount and the duration by weighing statutory factors such as the length of the marriage, each spouse's income and earning capacity, the marital standard of living, and contributions as a homemaker.
Because of that, an honest alimony calculator can't hand you a single number in every state. For guideline states, the tools above apply the real statutory equation and show each step. For factor-based states, they walk through the same factors a court considers and the typical duration, so you understand how a judge would approach your case rather than relying on a made-up figure.
