Overtime Pay Calculator
Use the overtime calculator to estimate weekly gross pay from regular hours and overtime hours. The multiplier can be adjusted for common 1.5x overtime or another applicable rate.

Regular pay, overtime pay and double time
The calculator separates regular earnings from premium earnings so the user can see exactly how extra hours affect weekly gross pay. Time-and-a-half uses a 1.5 multiplier; double time uses a 2.0 multiplier when that rate applies under an employer policy or state rule.
| Example | Formula | Gross pay effect |
|---|---|---|
| Regular hour | Hourly rate x 1.0 | Adds one base-rate hour. |
| Time-and-a-half | Hourly rate x 1.5 | Adds 50% more than a regular hour. |
| Double time | Hourly rate x 2.0 | Adds twice the regular hourly rate. |
Overtime scenario planning
The scenario cards compare no overtime, the entered overtime level and additional overtime. This answers whether a longer week is changing income meaningfully or only adding a small amount after taxes and commuting costs.
Worked example: five overtime hours
At $20 per hour, 40 regular hours and 5 overtime hours at 1.5x, regular pay is $800 and overtime pay is $150, for $950 weekly gross pay.
Worked example: double-time shift
At $24 per hour, a 6-hour double-time holiday shift adds $288 gross. If the worker also had 40 regular hours, weekly gross pay would be $1,248 before taxes.
Methodology
Regular pay equals hourly rate times regular hours. Overtime pay equals hourly rate times overtime multiplier times overtime hours. The calculator reports gross pay before tax withholding, benefits and deductions.
What changes the overtime result?
- The regular hourly rate changes both regular pay and overtime pay.
- The overtime multiplier has a direct effect on every premium hour.
- Extra hours may increase taxes withheld from a check, even when the annual tax rate is lower than the check feels.

Frequently asked questions
Is overtime always paid after 40 hours?
For many US non-exempt workers, overtime applies after 40 hours in a workweek, but job classification and state rules matter. This calculator estimates pay; it does not determine legal eligibility.
How do I calculate double time?
Enter 2.0 as the overtime multiplier. A $25 hourly rate at double time is $50 per premium hour before taxes.
Why is this gross pay instead of take-home pay?
Overtime calculators usually start with gross wages. Use the paycheck calculator afterward to estimate federal tax, FICA and optional state/local tax.
Can overtime affect benefits or deductions?
It can affect gross wages and withholding. Benefit deductions depend on employer payroll settings, so check a pay stub for the final treatment.
