Overtime Pay Calculator: Time and a Half, Regular Rate and Total Gross Pay for the Week

Under the Fair Labor Standards Act (FLSA), a non-exempt employee must receive at least 1.5 times the regular rate of pay for hours worked over 40 in a workweek. This overtime calculator shows regular pay, overtime hours, regular rate, overtime premium and total gross pay for one week or a biweekly pay period. Hours are tested per workweek and are never averaged across weeks.

How overtime pay is calculated

Straight-time pay = hourly rate x all hours worked. The regular rate of pay = total remuneration for the week (excluding statutory exclusions) divided by total hours worked. Nondiscretionary bonuses are included in the regular rate. Overtime premium = 0.5 x regular rate x overtime hours, because the straight-time portion of those hours is already inside straight-time pay. Total = straight-time pay + bonus + premium. When only an hourly rate is entered: total = rate x 40 + rate x 1.5 x (hours - 40). Hours are tested per workweek (a fixed 168-hour period) and are never averaged across weeks. For a bi-weekly overtime calculator result, enter hours for both weeks and choose the two-week pay period; each workweek is still tested on its own.

Example: $18.00 per hour for 48 hours gives $720.00 (40 x $18.00) plus $216.00 (8 x $27.00) = $936.00 total, with an overtime premium of $72.00 (8 x $9.00).

Common mistakes and key conditions

Averaging hours across two weeks. Each workweek stands alone under the FLSA.
Using the hourly rate instead of the regular rate when a nondiscretionary bonus applies.
Assuming a multiplier above 1.5 comes from federal law. It comes from employer policy or state law.
Assuming an employee is exempt from overtime. Exemption depends on salary and duties tests.
Counting daily overtime or double time as federal FLSA overtime unless a policy or state law provides it.

Frequently asked questions

How is overtime calculated?

Overtime is calculated per workweek: hours over 40 are paid at least 1.5 times the regular rate of pay. See U.S. Department of Labor Fact Sheet #23 and 29 CFR Part 778.

Do bonuses affect overtime?

Nondiscretionary bonuses are included in the regular rate of pay and can raise the overtime premium. Discretionary bonuses are excluded. See 29 CFR Part 778.

Can overtime be averaged over two weeks?

No. Hours are tested per workweek, a fixed 168-hour period, and averaging across weeks is not permitted under the FLSA.

Is overtime taxed more?

Overtime is taxed at the same rates as other wages. The federal qualified-overtime deduction (tax years 2025-2028) may allow a deduction of the premium portion only, subject to caps and phase-outs. This calculator shows only a limited estimate of the premium portion and does not prepare a tax return.

What is the no tax on overtime deduction?

Under the qualified overtime deduction, the pay that exceeds the regular rate (the "half" of time-and-a-half) may be deductible, with a cap of $12,500 ($25,000 if married filing jointly) and a phase-out above modified AGI of $150,000 ($300,000 joint), for tax years 2025 through 2028. Verify current IRS rules before filing.

Limitations, exclusions and assumptions

This calculator does not decide exempt status, does not compute taxes or take-home pay, does not apply state daily-overtime or seventh-day rules, and does not prepare a tax return. The qualified-overtime figure is a limited estimate of the premium portion only. Multipliers above 1.5 reflect user-entered policy or state law.
