The Spousal Maintenance Calculator Under Illinois Law

Statutory guidelines are used to determine the amount of maintenance if the combined gross income of the parties is less than $500,000.00 and the payor does not have a previous obligation to pay maintenance or support from a prior relationship.

The Illinois Marriage and Dissolution of Marriage Act (“IMDMA”) provides the following formula for determining maintenance:

Award Amount

The amount of spousal maintenance is determined by taking 33.3 percent of the payer’s net income and subtracting 25 percent of the payee’s net income. (33.3 -25 percent). In addition, it is important to note that the payee’s new net income cannot be greater than 40 percent of the parties combined income.

*Table does not reflect maintenance duration.

Each case is unique, however, and the maintenance amount is ultimately based on numerous factors besides each party’s income, such as the duration of the marriage, the earning capacity of each party, and a spouse’s need for further education or job training.

Award Duration

The duration of maintenance is how long the payer will legally be required to pay maintenance, or how long the payee will legally be awarded maintenance. To determine the duration of the award, take the length of the marriage and multiply it by the corresponding multiplying factor:

  • Married less than 5 years (0.20)
  • Married 5 years (0.24)
  • Married 6 years (0.28)
  • Married 7 years (0.32)
  • Married 8 years (0.36)
  • Married 9 years (0.40)
  • Married 10 years (0.44)
  • Married 11 years (0.48)
  • Married 12 years (0.52)
  • Married 13 years (0.56)
  • Married 14 years (0.60)
  • Married 15 years (0.64)
  • Married 16 years (0.68)
  • Married 17 years (0.72)
  • Married 18 years (0.76)
  • Married 19 years (0.80)
  • Married for 20 years or more, the court determines the duration of maintenance or orders permanent spousal support.

As an example, spousal support awarded to a payee in a 10-year marriage would be paid for 4.4 years.
