Alimony Calculator: 50 States

Divorce is one of the most financially shocking events of your life. Whether you are terrified of paying too much or anxious about receiving enough to survive, your attorney knows what your alimony will cost. Now, you do too.

Alimony Calculator: 50 States is a professional-grade spousal support tool built for real people. By analyzing marriage length, income disparities, and your exact state’s laws, we reveal the two numbers that actually matter: Your Monthly Amount and your Total Lifetime Value.

Most calculators use outdated pre-2019 tax laws or apply generic math to every state. We don't. We separate states with strict mathematical formulas (like IL, CO, NY, KS) from "judicial discretion" states, giving you a court-aligned estimate using American Academy of Matrimonial Lawyers (AAML) guidelines where applicable.

WHAT YOU WILL DISCOVER:
• The Lifetime Shock: See exactly how a 5-year vs. a 15-year marriage changes your total payout.
• Two Perspectives: Toggle instantly between the "Paying" and "Receiving" view.
• Tax Truths: Understand the permanent TCJA tax changes (alimony is NO LONGER federally deductible).
• Factor Multipliers: See how career sacrifice, health issues, or standard of living change the judge's math.

--FAQs--

How is alimony calculated in Illinois or Colorado?
The Alimony Calculator app uses exact state statutory formulas. For example, Illinois uses 33.33% of the payer's net income minus 25% of the recipient's net income. You can calculate your exact state formula inside the Alimony Calculator app.

Did Florida abolish permanent alimony?
Yes. Florida abolished permanent alimony in July 2023. The Alimony Calculator app automatically applies the new 2023 Florida durational alimony caps based on your exact length of marriage.

Can I get alimony in Texas?
Texas is highly restrictive. The Alimony Calculator app factors in the Texas rule requiring a 10+ year marriage, domestic violence, or disability to qualify for spousal maintenance.

Is spousal support tax deductible?
A: Under the federal TCJA rules (post-2018), alimony is NOT tax-deductible for the payer and NOT taxable income for the recipient. The Alimony Calculator app displays estimates reflecting these current federal tax realities.

How do I find out my total lifetime alimony cost?
You can use the App Functions in the Alimony Calculator to instantly generate a "Duration & Lifetime Value" report by inputting your gross income and marriage length in months and years.

Data Sources:
Formula-based estimates use official state statutes — Illinois (750 ILCS 5/504), New York (NY Domestic Relations Law §236(B)), Colorado (C.R.S. §14-10-114, advisory). States without a statutory formula we used the AAML professional guideline as a reference point, clearly labeled as an estimate, not law. Full state-specific sourcing is shown in the app. This is not legal advice.
