Illinois Overtime Calculator

How this state overtime estimate works

This Illinois overtime calculator estimates regular pay, overtime pay, estimated gross pay, and optional rough take-home pay. Enter total weekly hours, hourly rate, weekly threshold, and overtime multiplier. The default 40-hour threshold and 1.5x multiplier are a common starting point, not a legal conclusion.

Illinois overtime questions can involve both state law and federal law. The calculator helps with arithmetic once assumptions are chosen, but it does not decide whether a specific worker, job category, or pay arrangement is covered by a specific rule.

Illinois overtime and wage notes

The Illinois Department of Labor provides minimum wage and overtime resources that should be checked for state-specific wage and hour issues. Federal DOL sources are also relevant because many overtime questions involve federal FLSA concepts, including covered nonexempt status and the regular rate of pay.

Exemptions, job duties, salary arrangements, public employment, tipped work, commissions, bonuses, and industry-specific rules can all affect the result. Do not use a simple calculator as the only source for a payroll dispute.

Illinois weekly overtime example

Suppose an Illinois worker earns $25 per hour and works 45 hours in one workweek. With a 40-hour threshold, the calculator estimates 40 regular hours and 5 overtime hours. At 1.5x, overtime pay is estimated at $187.50 and regular pay is $1,000, for estimated gross pay of $1,187.50 before deductions.

What this calculator does not determine

This calculator does not determine Illinois overtime eligibility, exemption status, whether an employee is covered by a wage order or special rule, or whether every entered hour is compensable. It also does not calculate exact Illinois or federal withholding.

The optional deduction percentage is only a rough paycheck planning input. Actual take-home pay may include federal withholding, Illinois withholding, payroll taxes, benefits, retirement contributions, garnishments, and other deductions.

Official sources to check

Use Illinois Department of Labor minimum wage and overtime resources for Illinois-specific information. Use federal DOL overtime and regular-rate resources for FLSA baseline rules and regular-rate concepts.

If the week includes bonuses, commissions, shift differentials, or multiple rates, compare this weekly calculator with the more specific regular-rate tools on this site.

Common Illinois calculation mistakes

A common mistake is treating overtime as a tax category instead of a wage category. Overtime can increase withholding, but the gross overtime pay calculation comes first.

Another mistake is counting paid leave, holidays, or unpaid meal periods without checking whether they count as hours worked for the applicable overtime rule.
