Alimony & Spousal Support Estimator
Estimate a rough monthly spousal support range using a common income-based guideline.
Alimony has no single national formula. As a rough guideline, some courts start near 30% of the higher earner's gross income minus 20% of the lower earner's, paid monthly. Marriage length affects duration. Many states reject formulas and judges decide case-by-case, so this is general information only — confirm with a licensed family law attorney.
Frequently Asked Questions
How is alimony calculated?+
There is no single national alimony formula. This tool uses a common rough guideline that takes about 30% of the payer's gross monthly income and subtracts about 20% of the recipient's. Many states reject formulas entirely and let a judge decide based on each spouse's needs, earning capacity, and the standard of living during the marriage.
How long does alimony last?+
Duration usually depends on how long you were married. Marriages under 10 years often lead to shorter-term support, 10 to 20 years is commonly medium-length, and over 20 years may qualify for long-term or even indefinite support in some states.
Does every state use a formula for spousal support?+
No. Some states use guideline formulas, but many have no formula at all and leave the amount and length entirely to a judge's discretion. Whether your state is a community-property or equitable-distribution state can also change how support is decided.
What income is used for the alimony estimate?+
This tool uses each spouse's gross monthly income before taxes. Courts may also consider bonuses, self-employment income, investment income, earning potential, and other resources, so your real figure can differ from a simple income-based estimate.
Can the estimated alimony amount change later?+
Yes. Alimony orders can often be modified if circumstances change substantially, such as a job loss, a large income change, retirement, or the recipient remarrying or cohabiting. The rules for modification vary by state, so ask a family law attorney.
Why is the result shown as a range instead of one number?+
Because alimony is highly fact-specific and discretionary, a single figure would be misleading. The range (roughly 0.75 to 1.25 times the guideline base) reflects that real outcomes depend on your state's rules, the judge, and the details of your marriage and finances.
Is this tool legal advice?+
No. This tool provides general information only and is not legal advice. Results are estimates and every case is different — always consult a licensed attorney in your state about your specific situation.
