About the marriage
Your state and the length of the marriage set the starting range for everything that follows.
Support rules differ substantially between states, so this one is required.
How the estimate is produced
No formula can predict a judge. What this calculator does is apply the same factors a court applies, in the open, so you can see which of your circumstances move the number and by how much.
Your state sets the starting range
Each state anchors support to a different share of the paying spouse's income, with its own duration cap. Texas, for example, caps maintenance at the lesser of $5,000 a month or 20% of gross monthly income; most states set no cap at all.
Length of marriage and income gap scale it
Longer marriages and wider income gaps both push the figure up. These two inputs move the result more than anything else on the form.
Circumstances adjust it up or down
Employability, career sacrifice, caregiving, a prenuptial agreement, disability and marital misconduct each shift the range. The result is bounded by what the lower-earning spouse can show they need.
Calculators by state
Support law is state law, and the differences are large. Pick your state for the rules, duration guidance and case law that actually apply to you.

Understanding alimony in the United States
Alimony — called spousal maintenance or spousal support in many states — is a court-ordered payment from one former spouse to the other after a divorce. Its purpose is to let the lower-earning spouse keep a standard of living reasonably comparable to the one established during the marriage, for as long as it takes to become self-supporting.
Unlike child support, which most states calculate from a rigid formula, alimony is largely discretionary. A judge weighs the length of the marriage, each spouse’s income and earning capacity, the standard of living during the marriage, age and health, and contributions to the household — including homemaking and child-rearing. Two couples with identical finances can receive different awards from different judges in the same courthouse.
That discretion is why this tool produces a range rather than a figure. Treat the range as the territory a negotiation is likely to happen in, and take it to a family law attorney licensed in your state before you rely on it.
