Illinois Spousal Maintenance (Alimony) Calculator
Divorce often brings major financial questions, and one of the most important is whether one spouse will owe ongoing support to the other. In Illinois, this type of financial assistance is known as spousal maintenance (sometimes referred to as alimony).
At the Law Office of Fedor Kozlov, P.C., we know that financial security is one of the biggest concerns during and after a divorce. To help you get a general idea of what spousal maintenance could look like in your situation, we’ve created this calculator. It uses the Illinois statutory formula to provide an estimate of monthly support.
How Maintenance Is Calculated in Illinois
Illinois law provides a basic formula for calculating spousal maintenance when there is a significant difference in income between the spouses. The court looks primarily at:
- The annual net income of each spouse (income after taxes).
- The length of the marriage, which helps determine how long support may last.
The statutory calculation is generally:
Maintenance = 33.3% of the higher-earning spouse’s net income – 25% of the lower-earning spouse’s net income.
There is also a cap: the spouse receiving maintenance cannot end up with more than 40% of the couple’s combined net income once support is added.
This guideline applies to most cases, but judges always have discretion to adjust support based on factors such as:
- Prior agreements (like a prenuptial agreement)
- Significant assets or debts
- High net worth cases
- The lifestyle established during the marriage

Inputs Needed:- Higher-earning spouse’s annual net income
- Lower-earning spouse’s annual net income
- Length of marriage (in months)
Our calculator will then give you an estimated maintenance figure based on Illinois law.
This tool gives a general estimate of spousal maintenance under Illinois guidelines. It does not consider property division, debts, or special financial circumstances. Actual court-ordered maintenance may differ depending on the details of your case.

Why This Is Only a Starting Point
Every family’s financial circumstances are different. Judges may consider more than just income when deciding maintenance, and sometimes unique financial arrangements make the formula less straightforward.
That’s why our calculator is meant as a helpful estimate, not a guarantee. For clear answers, it’s important to speak directly with an attorney who can review your full financial picture.
