β° Illinois Overtime Calculator
Time-and-a-half pay for hours over 40 in Illinois.
Gross weekly pay with overtime
Estimates for planning only, not financial advice.
Illinois overtime law mirrors the federal standard: 1.5 times your regular rate for every hour past 40 in a workweek. Illinois adds its own enforcement muscle through the state Department of Labor, and Chicago workers should know the city has some of the strongest local labor protections in the country, though the overtime rate itself stays at time and a half. Illinois minimum wage is well above the federal floor, which lifts the overtime rate for hourly workers across the state.
How to Use This Calculator
Enter your hourly rate, your regular hours for the week, and how many hours you worked past 40. The calculator applies the federal time-and-a-half rule and splits your paycheck into regular pay and overtime pay so you can check it against your pay stub.
Enter your regular hourly rate, the number on your offer letter or pay stub, not a blended rate.
Enter regular hours (usually 40) and overtime hours separately. If you worked 48 hours, that is 40 regular plus 8 overtime.
Read your overtime rate, overtime pay, and gross weekly pay. To turn the weekly number into take-home pay, run it through our paycheck calculator.
The Overtime Formula
Illinois overtime law mirrors the federal standard: 1.5 times your regular rate for every hour past 40 in a workweek. Illinois adds its own enforcement muscle through the state Department of Labor, and Chicago workers should know the city has some of the strongest local labor protections in the country, though the overtime rate itself stays at time and a half. Illinois minimum wage is well above the federal floor, which lifts the overtime rate for hourly workers across the state.
Worked Example
Take a warehouse lead in Chicago earning $22 an hour who works 46 hours. Regular pay is 40 x $22 = $880.00. The overtime rate is $22 x 1.5 = $33.00 an hour, and 6 overtime hours pay 6 x $33.00 = $198.00. Gross weekly pay is $1078.00. Those 6 extra hours were worth $198 instead of $132 at straight time, a $66 premium the law guarantees. Over a full year of steady 46-hour weeks, that premium alone is worth about $3,432.
Overtime Tips Worth Knowing
First, Illinois lets you file a wage claim with the state Department of Labor for free, and the state can investigate on your behalf. You do not need a lawyer to start. Second, watch for the salary trap: Illinois follows the federal $684-per-week salary threshold for exempt status. A $40,000 salary sounds exempt until you divide it: $769 a week clears the threshold, but only if the duties test is also met. Job title alone never decides exemption. Third, meal breaks. Illinois requires a 20-minute meal break for shifts of 7.5 hours or more, and bona fide meal breaks are unpaid and do not count toward the 40. If you work through lunch, those minutes count as hours worked.

Frequently Asked Questions
Does Illinois have its own overtime law?
No. Illinois follows the federal Fair Labor Standards Act, which requires overtime at 1.5 times the regular rate for hours worked over 40 in a single workweek. There is no daily overtime threshold and no state rule that pays more than the federal floor.
What counts as hours worked for overtime?
Almost all time you are required to be on duty counts: regular shifts, mandatory training, and travel between job sites during the day. Meal breaks where you are fully relieved of duty usually do not count. Paid time off like vacation or holidays counts only if your employer chooses to include it; the law does not require it.
Is overtime calculated daily or weekly?
Weekly. Federal law looks at total hours in the workweek, which is a fixed 7-day period your employer defines. Working 10 hours on Monday and 6 on Tuesday creates no overtime by itself; only the weekly total past 40 triggers the premium. A few states have daily rules, but Illinois is not one of them.
Does my employer have to pay overtime on bonuses?
Nondiscretionary bonuses, the kind you earn by hitting a target, must be folded into your regular rate before overtime is figured, which raises the overtime rate slightly. Discretionary bonuses like a surprise holiday gift do not. If your bonus is promised in advance for performance, assume it counts.
Are salaried workers exempt from overtime?
Some are, some are not. Being paid a salary does not by itself make you exempt. Under federal rules you must also do exempt-type duties and earn at least $684 per week. Millions of salaried workers under that threshold are legally owed overtime, and misclassification is one of the most common pay violations.
Can my boss offer comp time instead of overtime pay?
In the private sector, no. Federal law does not let private employers swap overtime pay for future time off, even if you agree to it. Public-sector employers can offer comp time under strict rules. If a private employer offers "comp time" for your extra hours, that is a red flag.
What if I work two different hourly rates in one week?
Your overtime rate is based on the weighted average of the rates you actually worked, called the regular rate. Add up all straight-time earnings for the week, divide by total hours, then multiply by 1.5 for each overtime hour. This calculator assumes a single rate; with two rates, compute the weighted average first.
How far back can I claim unpaid overtime?
Federal law gives you two years to recover back wages, stretched to three years if the violation was willful. State wage-claim deadlines vary. Keep your own log of hours worked, because employer records are not always complete, and talk to your state labor agency or an employment lawyer quickly if you suspect underpayment.
Does Chicago have different overtime rules?
The overtime rate is the same 1.5x statewide. Chicago adds strong local protections on scheduling, paid leave, and minimum wage, enforced by the Office of Labor Standards, but overtime math follows state and federal law.
Where do I file an unpaid overtime claim in Illinois?
File with the Illinois Department of Labor, which investigates wage claims at no cost to you, or with the federal Wage and Hour Division. You can also sue in court. Illinois law adds penalties and attorney fees for willful violations, which is why many claims settle.
