How does this calculator work?
Illinois overtime follows federal FLSA: gross pay = (hours ≤ 40 × rate) + (hours > 40 × rate × 1.5). The overtime rate is always 1.5× the regular hourly rate; Illinois sets no separate threshold. The 2025 Illinois minimum wage is $15.00/hr. Result is gross pay before taxes.
Formula
How this is calculated
Illinois does not set its own overtime rate — it enforces the federal FLSA, which requires non-exempt employees to receive at least 1.5 times their regular rate for every hour worked beyond 40 in a single workweek. A workweek is a fixed, recurring 168-hour period (7 consecutive days) chosen by the employer; overtime resets at the start of each new workweek.
This calculator splits total hours into two segments: up to 40 hours at the regular rate, and any hours above 40 at the 1.5× overtime rate. The effective hourly rate is the blended average across all hours — it rises as overtime hours increase, reflecting the higher per-hour compensation.
The Illinois Minimum Wage Law sets a floor of $15.00/hour for most workers in 2025 — always use the higher of your actual rate and the legal minimum. Tipped employees, some agricultural workers, and employees under 18 for limited hours may qualify for different rates. This calculator shows gross pay before federal income tax, Illinois income tax, Social Security, and Medicare.
Frequently asked questions
Illinois enforces the federal FLSA 40-hour workweek overtime threshold rather than adding a higher standard. Illinois does set its own minimum wage ($15.00/hr in 2025), which forms the base for overtime calculations. Some collective bargaining agreements or employment contracts may provide more generous overtime terms.
Illinois (and federal) overtime is based on hours in a 7-day workweek, not on daily hours. You must exceed 40 hours in the same workweek before overtime applies. There is no mandatory daily overtime for most private-sector employees, though employers may voluntarily pay it.
Executive, administrative, and professional employees who earn above the FLSA salary threshold ($684/week in 2024) and pass a duties test are generally exempt. Certain agricultural workers, seasonal employees, and some commission-based salespeople may also be exempt. Check the Illinois Department of Labor website for guidance on your specific job classification.
