Alimony Calculator for Illinois Couples

The allocation of alimony, also referred to in Illinois as spousal support or spousal maintenance, is governed by the Illinois Marriage and Dissolution of Marriage Act. In 2019, these laws were changed significantly, and the formulas below apply to all divorces that were filed in 2019 or later.

The basic formula for alimony in Illinois is fairly simple:
(33% of the payer’s net income) – (25% of the recipient’s net income) = the yearly maintenance paid.

One condition to this is that the amount awarded cannot cause the receiving spouse to earn more than 40% of the couple’s combined net income.

How Long Will My Spousal Maintenance Payments Last?

In Illinois, the length of spousal support or maintenance payments will be largely dependent on the length of the marriage. The length of payments will be a percentage of the years of marriage, and the percentage increases with the length of the marriage, as shown below.

  • 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: Courts can choose to order permanent spousal maintenance or maintenance for a length equal to the length of the marriage.

This means that if alimony is ordered following a 10-year marriage, the payments will last for 4.4 years.

Remember that these are only the basics of how spousal support is calculated, and other factors can influence the amounts.

Are There Exceptions to the Illinois Spousal Maintenance Formula?

Generally speaking, the formulas described above will apply as long as a couples’ combined annual income is less than $500,000, and the paying spouse is not already under any previous child support orders. However, even outside of these circumstances, the same formulas are often used for determining support.

Illinois Spousal Maintenance Calculation Examples

Payer’s Monthly Income Receiver’s Monthly Income Estimated Monthly Maintenance Award
$3,000 $1,000 $600
$4,000 $1,000 $1,000
$5,000 $1,000 $1,300
$6,000 $1,000 $1,600
$7,000 $1,000 $1,900
$8,000 $1,000 $2,200

* Note: The above table does not reflect maintenance duration.

Will I Be Awarded Alimony in Illinois?

Spousal maintenance is meant to help a former partner gain independence who may otherwise struggle financially after the divorce. But it’s important to note that support is not awarded in all Illinois divorces. The factors that will be considered when determining if alimony is necessary include:

  1. Each spouse’s income and property, with consideration to the division of marital assets
  2. Each spouse’s financial need
  3. The current and future earning potential of both spouses
  4. Any negative impacts on the earning potential of the spouse seeking maintenance due to marriage or childcare arrangements
  5. Any potential impairment to the earning potential of the spouse paying maintenance
  6. The length of time needed for the spouse receiving maintenance to seek education or job training to improve their earning potential
  7. The standard of living established during the marriage
  8. How long the marriage lasted
  9. Other factors potentially related to employability, such as a spouse’s age or physical health
  10. Any other sources of public or private income
  11. Tax obligations that may be created by the division of marital property
  12. Contributions one party may have made to the education or earning potential of the other partner
  13. Any prenuptial or post-nuptial agreements
  14. Factors deemed by the court to be “just and equitable”
