Alimony Calculator by State
Alimony, called maintenance in New York and Texas and spousal support in California, is far less formulaic than child support. Some states cap it by statute, some publish a temporary formula, and some leave it to the judge. Pick your state to see how the number is actually set.

Formula states and factor states
New York and Illinois are the clearest formula states: statutory calculations produce a presumptive amount, with an income cap in New York and a 40% cap plus duration multipliers in Illinois. Texas does not use a formula but caps maintenance at the lesser of $5,000 per month or 20% of the payer's gross income and limits how long it can last. Florida's 2023 reform capped durational alimony at 35% of the difference in net incomes with duration limits tied to the marriage length.
California, Pennsylvania and Virginia use formulas only for temporary support while the case is pending: a county guideline in California, the 33% / 40% and 25% / 30% rule in Pennsylvania, and the 27% / 50% and 26% / 58% statute in Virginia. Long-term support after judgment in those states is based on statutory factors, with no formula at all.
What the calculators show
Each state page estimates the statutory ceiling or guideline amount and the maximum or advisory duration, then explains eligibility, the factors a court weighs, and when support ends. Because alimony depends on need and ability to pay, treat the result as the outer boundary of what a court is likely to order rather than a prediction.
Frequently asked questions
Is alimony automatic after a long marriage?
No state awards alimony automatically. The requesting spouse must show need and the other spouse's ability to pay, and in Texas must also fit a narrow eligibility category. Marriage length mostly affects how long support can last.
Is alimony still tax deductible?
Not for federal purposes in divorces finalized after 2018: the payer cannot deduct it and the recipient does not report it. California still allows the deduction on state returns, which its courts factor into the amount.
Can alimony be changed later?
Usually yes, on a substantial change in circumstances such as job loss or retirement, unless the parties agreed it would be non-modifiable. Remarriage of the recipient ends alimony in every state covered here.
