How Illinois overtime is calculated

Illinois follows the federal Fair Labor Standards Act (FLSA) weekly overtime standard.

  1. Split regular and overtime hours

    Regular Hours=min⁡(H,40),OT Hours=max⁡(H−40,0)\text{Regular Hours} = \min(H, 40), \quad \text{OT Hours} = \max(H - 40, 0)

    The first 40 hours in a 7-day workweek are regular hours. Any hours beyond 40 are overtime hours.

  2. Calculate overtime rate

    OT Rate=Regular Rate×Multiplier\text{OT Rate} = \text{Regular Rate} \times \text{Multiplier}

    $20.00 × 1.5 = $30.00/hr

  3. Sum gross weekly earnings

    Gross Pay=(Regular Hrs×R)+(OT Hrs×OT Rate)+Tips\text{Gross Pay} = (\text{Regular Hrs} \times R) + (\text{OT Hrs} \times \text{OT Rate}) + \text{Tips}

    (40 × $20.00) + (8.0 × $30.00) + $0.00 = $1,040.00

Illinois follows federal FLSA overtime standards under the Illinois Minimum Wage Law. Non-exempt employees earn at least time and a half for hours beyond 40 in a workweek. Calculations reflect FLSA overtime rules for the 2026 calendar year. Illinois does not require daily overtime for hours beyond 8 in a single workday. Actual pay may differ based on employer policies, tip credits, and exemption status.

How Illinois overtime pay works

Illinois follows federal Fair Labor Standards Act (FLSA) overtime rules. Non-exempt employees must receive at least time and a half for hours worked beyond 40 in a single workweek. Illinois has no daily overtime requirement, so a 12-hour shift on one day still pays straight time unless your weekly total exceeds 40 hours. This calculator estimates regular wages, overtime pay, tip adjustments, and total weekly gross earnings.

Enter your hourly wage, hours worked in the week, and optional tips. For a general overtime overview, use the overtime pay calculator. For states with daily overtime laws, compare with the California overtime calculator. To estimate take-home pay after Illinois's 4.95% flat state tax, use the Illinois paycheck calculator.

Illinois overtime formulas under FLSA

Illinois defers to federal law for overtime thresholds. Weekly gross pay follows these equations:

OT Hours=max⁡(H−40, 0)\mathrm{OT\ Hours} = \max(H - 40,\ 0)
OT Rate=w×1.5\mathrm{OT\ Rate} = w \times 1.5
Total Gross=(40×w)+(OT Hours×OT Rate)+Tips\mathrm{Total\ Gross} = (40 \times w) + (\mathrm{OT\ Hours} \times \mathrm{OT\ Rate}) + \mathrm{Tips}

H is total hours worked in the workweek and w is your regular hourly wage. Illinois also requires one day of rest in seven for certain retail and service employers, but that rule does not create a separate daily overtime rate. Premium pay still follows the federal weekly 40-hour threshold.

No daily overtime in Illinois

Unlike California, Illinois does not mandate premium pay when you work more than 8 hours in a single day. Only the weekly 40-hour FLSA threshold triggers overtime. An employee who works five 8-hour days (40 hours) earns straight time for all hours. A sixth 8-hour day adds 8 overtime hours at 1.5x the regular rate.

Worked example: 44-hour week at $25.00 per hour

An Illinois healthcare worker earns $25.00 per hour and works 44 hours in one week:

  1. Regular pay: 40 hours x $25.00 = $1,000.00.
  2. Overtime hours: 44 - 40 = 4 hours at $37.50 (1.5 x $25.00) = $150.00.
  3. Total gross pay: $1,000.00 + $150.00 = $1,150.00.
  4. Effective hourly rate: $1,150.00 / 44 = $26.14 per hour.

After federal and Illinois state taxes, net pay will be lower. Model your paycheck with the Illinois paycheck calculator or isolate state tax with the Illinois tax calculator. If your hourly rate changes, use the pay raise calculator.

Who qualifies for overtime in Illinois

Most hourly workers in Illinois are non-exempt and entitled to FLSA overtime. Exempt employees in executive, administrative, professional, and certain other roles who meet federal salary and duties tests may not receive overtime. Illinois minimum wage laws apply separately from overtime rules and do not change the 40-hour weekly threshold.
