Illinois Maintenance Guidelines
Estimate Your Spousal Maintenance
When an Illinois court awards spousal maintenance — often called alimony — it generally starts from a statutory formula rather than a judge’s discretion alone. This calculator applies that guideline formula, along with the statutory cap that limits how much of the combined household income the receiving spouse may end up with.
Use it to get a rough sense of the numbers before your first conversation with an attorney. It is a starting point for a discussion, not a prediction of what a court will order.
How to use this calculator
- Enter the paying spouse’s annual income, then the receiving spouse’s. Use annual figures, not monthly.
- Use net income where you can — gross income minus taxes and certain statutory deductions. If you only know gross figures, the result will run high.
- Select Calculate Estimate to see the guideline annual and monthly amounts.
- Bring the result to a consultation. Deviations from the guideline are common, and the numbers here do not account for the duration of the award.
