The default models the federal baseline for covered, nonexempt employees: time and one-half after 40 hours in a workweek. State law, exemptions, contracts, bonuses, and multiple pay rates can change the correct result.
The federal overtime baseline
Under the Fair Labor Standards Act, covered employees who are not exempt generally must receive at least one and one-half times their regular rate for hours above 40 in a workweek. A workweek is a fixed period of seven consecutive 24-hour periods.
Federal law does not automatically require premium pay simply because work occurs on a weekend or holiday. The weekly hours and the employee's coverage and exemption status matter.
- Confirm whether the employee is covered and nonexempt.
- Use the regular rate, which can include some nondiscretionary compensation.
- Do not average hours across two separate workweeks.
- Check state rules and employment agreements for stronger protections.
What the simple model leaves out
The calculator assumes one regular hourly rate. Piece-rate work, commissions, nondiscretionary bonuses, shift differentials, and multiple hourly rates may require a different regular-rate calculation.
It also does not determine whether a job is exempt. Job title or salary alone does not settle that legal question.
Use the result as a wage check
Compare the estimate with a pay stub by separating straight-time earnings and overtime premium. If the figures do not match, review the pay period, hours assigned to each workweek, regular-rate components, and applicable state law.
For an employment dispute or classification question, contact the appropriate labor agency or an employment professional.
The formula used
Weekly pay = regular hours × regular rate + overtime hours × regular rate × overtime multiplierRegular hours are capped at the entered threshold. Hours above the threshold are multiplied by the entered premium, which defaults to 1.5.
Example: 48 hours at $22
At $22 per hour, 48 hours worked, a 40-hour threshold, and a 1.5× multiplier, regular pay is $880 and overtime pay is $264. Estimated weekly gross pay is $1,144.
