Use the Alimony Calculator above to estimate your spousal maintenance in the state of Illinois. The calculator uses the guideline method to estimate spousal support. This method employs a standard formula: (33.3% of the payer’s monthly net income) – (25% of the receiver’s monthly net income) = monthly spousal maintenance amount. The calculated payments cannot exceed 40% of the combined net income of both parties. Additionally, the duration of spousal support is standardized based on the length of the marriage.

The purpose of the Alimony Calculator is to give you an idea of what your spousal maintenance payments may look like depending on the circumstances of your case.
