Illinois Weekly Benefit Amount Calculator: Instructions and Explanations

Date Claim Filed

Enter the date that you filed your claim (or will file your claim) for unemployment.

Illinois will usually consider your claim effective as of Sunday of the same week that you file. This affects which quarterly earnings are considered as your base period (see below) when calculating your weekly benefit amount.

Base Period: Calendar Quarters | Wages Earned

Enter your total wage earnings for each of the four calendar quarters listed, which are the first four of the most recent five completed calendar quarters. You must have earned at least $1,600 combined in order to qualify for benefits. After excluding your highest-earning quarter, you must also have earned at least $440 combined, in order to qualify for benefits.

The two quarters with the highest earnings will then be used to calculate your WBA.

If you do not qualify under the standard base period, you may be able to use the most recent four completed quarters as an alternate base period.

Dependent Spouse

Select if you have a dependent spouse for whom you provided more than 50% of the cost of support during the 90-day period prior to filing your application.

Dependent Children

Enter the number of your dependent children for whom you provided more than 50% of the cost of support (25% if your spouse also provided support and you live in the same household as your spouse) during the 90-day period prior to filing your application, and either are (a) under 18 years of age, or (b) disabled and unable to work.

Estimated Weekly Benefit Rate (WBA)

The calculator returns your estimated WBA based on your average weekly wage during the base period.

Your WBA is approximately 47% of your average weekly wage, based on your two highest-earning quarters. You receive an additional 9% if you have a dependent spouse and an additional 17.9% per a dependent child. You cannot claim both a dependent spouse and dependent child(ren).

The maximum WBA varies depending on the number of qualifying dependents. If you have no dependents, your maximum WBA is $484. If you have a dependent spouse but no dependent children, your maximum WBA is $577. If you have dependent children (regardless of spouse, since you cannot claim both a spouse and children), your maximum WBA is $669.

These maximums are recalculated annually on July 1 based on the statewide average weekly wage.

The calculator will return an estimated weekly benefit rate of $0, if it appears that you do not meet the eligibility requirements described above.

Your WBA may be reduced by other compensation that you receive and certain mandated payments, such as delinquent child support payments.

Maximum # of Weeks

The maximum number of weeks for which you can receive your WBA is 26 weeks.
