How Is Overtime Pay Calculated? A Plain-English Guide

For a simple U.S. example, overtime at time-and-a-half means 1.5 times the applicable regular hourly rate for each qualifying overtime hour. If the regular rate is $20 and the worker has 5 overtime hours, those hours add $150 at the overtime rate ($20 × 1.5 × 5). The exact calculation can be more involved when bonuses or other pay affect the regular rate, and not every worker or hour is covered by the same rules.

Start with the workweek, not the pay period

The federal Fair Labor Standards Act (FLSA) generally requires covered, nonexempt employees to receive at least one-and-one-half times their regular rate for hours worked over 40 in a fixed workweek. The U.S. Department of Labor says the workweek is a fixed, recurring period of seven consecutive 24-hour days; it may begin on any day and need not match a calendar week. Hours cannot simply be averaged across two or more weeks. Read the current DOL overtime overview for the federal baseline.

That does not mean every employee automatically qualifies for the same calculation. Coverage, exemption status, state or local law, industry-specific rules, and the facts of the job matter. A salary or job title alone does not settle exemption status. Rules can change, so check official federal and applicable state guidance for a real dispute. This article describes a basic illustration, not a determination of your rights.

The basic formula

When the regular hourly rate is known and the simple time-and-a-half assumption applies:

Overtime premium rate = regular rate × 1.5

Overtime earnings = overtime premium rate × qualifying overtime hours

If the employer already paid the regular rate for every hour, the additional premium needed to reach 1.5 times may be shown as a separate half-time amount. A pay stub might instead list the overtime hours at the full 1.5 rate. Check the employer’s payroll presentation before adding line items, or you could count the regular portion twice.

Worked example: hourly employee with 46 hours

Assume a covered, nonexempt hourly employee has a $24 regular rate, works 46 hours in one workweek, and has no bonus, differential, or other pay affecting the rate. Assume the first 40 hours are paid at $24 and the remaining 6 at 1.5 times that rate.

• Regular earnings: 40 × $24 = $960.
• Overtime rate: $24 × 1.5 = $36 per hour.
• Overtime earnings: 6 × $36 = $216.
• Illustrated gross pay: $960 + $216 = $1,176.

This is gross pay before deductions. It assumes all 46 hours count as hours worked, that the overtime threshold and rate stated apply, and that there are no regular-rate adjustments. It does not estimate taxes or net deposit. A biweekly pay period with 46 total hours is not enough to perform the calculation by itself; you need to know how many hours fell in each workweek.

Why the regular rate may differ from base pay

For some nonexempt employees, the overtime “regular rate” can include certain additional compensation, such as some nondiscretionary bonuses or differentials. Some payments may be excluded under applicable rules. Therefore, multiplying only the base hourly wage by 1.5 can understate or misstate overtime when other earnings are involved. The DOL’s Fact Sheet #56A on the regular rate discusses this federal concept; check its current text and related guidance for details.

Other work arrangements—including certain salaried nonexempt, piece-rate, commission, or fluctuating-workweek situations—may use different calculation steps. Do not assume a flat salary cancels overtime or that every overtime hour is paid using the example above. State law may require a higher rate, daily overtime, or other protections. For potential underpayment, preserve pay stubs, schedules, time records, and bonus details, and contact an appropriate labor agency or qualified professional.

Practical overtime check

1. Find the employer’s established seven-day workweek and list hours separately for each week.
2. Compare recorded hours with schedules and time records, including work that may have been required beyond a shift.
3. Confirm the pay basis and overtime classification with the employer, but do not treat a title or salary as conclusive.
4. Identify base wages, bonuses, differentials, and other compensation that may affect the regular rate.
5. Recalculate one workweek under applicable official guidance; compare the result with the stub without double-counting regular pay.
6. If something does not reconcile, ask payroll for the calculation and keep the response and supporting records.
