Required details

These inputs drive the estimate amount, duration, and state rules.

Step 1

Your State *

State rules drive both amount and duration.

Length of Marriage *

Use total years married; decimals are fine.

Paying Spouse Annual Income *

Use gross annual income unless your state formula says otherwise.

Receiving Spouse Annual Income *

Include regular wages, salary, and recurring income.

Number of Children *

Child Support Included? *

Choose yes if a child-support amount is already part of your scenario.

Optional adjustmentsAdd insurance or existing obligations when they materially affect cash flow.Show

Monthly Health Insurance Cost

Existing Support Obligations (annual)

Complex facts like disability, career sacrifice, unusual assets, or misconduct can materially change outcomes. The calculator treats those as attorney-review issues instead of pretending they convert cleanly into a dollar amount.

General (U.S.) formula (educational)

30% of paying spouse income − 20% of receiving spouse income

Annual estimate = (30% of paying spouse income − 20% of receiving spouse income), adjusted for marriage length, existing obligations, caps, and court-review factors.

Under 5 years: 1–3 years · 5–10 years: 3–5 years · 10–20 years: 5–10 years · 20+ years: long-term support likely

Frequently Asked Questions

How accurate is this alimony calculator?+

This tool provides educational estimates based on simplified formulas and general guidelines. Actual court awards depend on state law, judge discretion, and case-specific evidence. Always consult a family law attorney.

What is the alimony formula used?+

Formulas vary by state. California uses a 40%/50% gross-income guideline for estimates; Texas caps maintenance at $5,000/month or 20% of payer income; Illinois uses 33.33% payer net minus 25% recipient net; New York and Florida use their own guideline structures. Select your state in the calculator for the matching formula.

Does alimony vary by state?+

Yes - significantly. Each state page uses a different simplified formula, duration rules, and eligibility notes based on local spousal support law. California, Texas, Florida, New York, and Illinois each produce different estimates from the same inputs.

Is this legal advice?+

No. SettleCompass is an educational resource only. We are not a law firm and do not provide legal advice. Use these estimates for planning and research, not as a substitute for professional counsel.

How long does alimony typically last?+

Duration depends on marriage length and state law. Short marriages (under 5 years) often see 1 to 3 years of support. Marriages of 10 to 20 years may see 5 to 10 years. Marriages over 20 years may result in long-term support.
