Illinois Unemployment Benefits Calculator
Estimate your Illinois unemployment benefits. Max weekly: $859. Max weeks: 26. Free calculator.
Estimate only — these are not official figures
The weekly benefit applies Illinois's cited statutory method but deliberately APPROXIMATES the state's published benefit table or an un-reverified parameter (see methodology), so it is an estimate rather than an exact agency lookup. The monthly figure is weekly x 4.33 (a convention, not a statutory amount), and the tool does not perform a monetary-eligibility determination. The maximum weekly benefit ($859) and duration (26 weeks) are source-backed.
Do not rely on these amounts for budgeting or payment. For exact amounts, check the Illinois's state unemployment insurance agency (file there and use its official benefits estimator for your actual Weekly Benefit Amount determination).

How This Calculator Works
Calculation methodology and assumptions
Illinois calculates your "average weekly wage" (AWW) as your combined wages in your 2 highest-earning base-period quarters, divided by 26, rounded to the nearest dollar (820 ILCS 405/401(B)). Your Weekly Benefit Amount (WBA) is then 47% of that AWW, rounded UP to the next higher dollar, floored at $51 and capped at $628. IMPORTANT DEPENDENT-ALLOWANCE DISCLOSURE: Illinois law (820 ILCS 405/401(C)) also pays a separate nonworking-spouse allowance and a dependent-child(ren) allowance, which is why the U.S. DOL's own published range shows a higher $77 minimum / $859 maximum "with dependents." This calculator does NOT compute those allowances — Illinois's dependent-child rate floats between 17.0% and 17.9% of AWW and is redetermined every year, and this pass could not independently confirm the current-year rate or Illinois's live statewide average weekly wage from IDES. Rather than invent a number, dependentBonus is always shown as $0 here; if you have dependents, use IDES's own BEN-548 Table of Weekly Benefit Amounts for your exact figure. Your maximum total benefit is the lesser of 26 times your WBA or your FULL base-period wages (not a fraction, unlike most other states) — 820 ILCS 405/403(B). Duration is a uniform 26 weeks.
Key State Information
Illinois's maximum weekly UI benefit (no dependents) is $628, with a $51 minimum — both rise with dependents (up to $859 max / $77 min per the DOL's published range), but this calculator does not compute the exact dependent-inclusive figure this pass (see methodology). Standard duration is a uniform 26 weeks.
How to Use This Unemployment Calculator
- 1
Enter your prior earnings
Input your gross earnings from the past 12-18 months (the "base period"). Illinois use the highest quarter or recent quarters of earnings to determine your weekly benefit amount.
- 2
Enter your employment details
Indicate how you became unemployed. You must have lost your job through no fault of your own (layoff, company closure, reduction in force) to qualify. Voluntary quitting and termination for cause typically disqualify you.
- 3
Select your state
Illinois administers its own unemployment program with different benefit amounts, duration, and eligibility rules. Published weekly maxima currently range from $235 (Mississippi) to $1,208 (Washington).
- 4
Review your benefit estimate
The calculator shows your estimated weekly benefit amount, maximum duration (typically 26 weeks), and total estimated benefits. Compare to your essential expenses to plan your job search timeline.
Example Calculation
Let's review the source-backed unemployment inputs for Illinois.
Illinois uses a state-specific statutory formula rather than the site's simplified 50%-of-wage fallback. Enter the exact quarter/base-period wage and eligibility fields requested by the calculator; the required inputs differ by state and cannot be reconstructed safely from median household income.
Result: Published maximum weekly amount: $859. Current maximum duration: 26 weeks. These are ceilings, not a typical award; the calculator above applies Illinois's source-backed formula to your own wage history, and only the state agency determines eligibility.
What Affects Your Results
Prior Earnings
Benefits are calculated from your "base period" earnings (typically the first 4 of the last 5 completed quarters). Higher earnings yield higher benefits, up to the state maximum cap.
State Maximum
Weekly maximums vary enormously: Mississippi ($235), Arizona ($320), California ($450), New York ($869), Washington ($1,208). Illinois's cap may be well below 50% of prior wages.
Reason for Separation
Layoff/reduction in force: eligible. Company closure: eligible. Fired for cause: usually ineligible. Quit voluntarily: usually ineligible unless for "good cause" (harassment, unsafe conditions, spousal relocation in some states).
Duration
Standard benefits last 26 weeks in most states (some offer 12-30 weeks). During recessions, federal extensions may add 13-20 additional weeks. After exhaustion, there are generally no further benefits.
Tips for Illinois Residents
- File for unemployment the day you're separated — don't wait. Illinois have a 1-week waiting period and 2-4 weeks processing time. A week's delay could mean 3-5 weeks without income.
- Unemployment benefits are taxable income (federal and most states). Opt for voluntary withholding (10% federal) to avoid a surprise tax bill. Many people spend the full benefit not realizing taxes are due.
- You must actively search for work and document your efforts to maintain eligibility. Most states require 3-5 job contacts per week. Keep a detailed log — random audits happen.
- Freelance or gig work while on unemployment may reduce (but not eliminate) your benefits. Most states allow you to earn 25-50% of your weekly benefit before reducing the payment. Report ALL earnings — fraud has serious consequences.
- Explore Illinois's additional programs: job training (WIOA), trade adjustment assistance, extended benefits during high unemployment, and reemployment services. These are underutilized but valuable.

Our editorial standardsFrequently Asked Questions
How much is unemployment in Illinois?
Illinois pays 47% of your average weekly wage (combined wages in your 2 highest quarters ÷ 26), floored at $51 and capped at $628/week before any dependent allowance. A worker with $26,000 combined in their 2 highest quarters would get an estimated $470/week.
Does Illinois pay extra for dependents?
Yes — 820 ILCS 405/401(C) pays a nonworking-spouse allowance and a separate dependent-child(ren) allowance, which is why Illinois's published maximum rises to $859/week (minimum to $77) with dependents. This calculator does not compute the exact dependent-inclusive amount because Illinois's dependent-child rate is redetermined annually (17.0%-17.9% of your average weekly wage) and this pass could not independently confirm the current year's rate — check IDES's official Table of Weekly Benefit Amounts for your exact figure.
How long do Illinois unemployment benefits last?
A uniform 26 weeks for all approved claims, capped at the lesser of 26 times your weekly benefit amount or your full base-period wages (820 ILCS 405/403(B)).
