Overtime Pay Calculator
Gross pay with overtime from hourly rate, regular hours, and OT hours.
What it does
Overtime pay compensates extra hours above the standard week at a premium rate. US federal law sets time and a half past forty hours for covered nonexempt workers, and states, unions, and weekend rules can raise it to double time.
The tool above multiplies regular and overtime hours by the right rates and totals gross pay for the period. Pick the multiplier that matches the contract or law.
Exempt status decides eligibility more than salary does. Managers, professionals, and outside sales often sit exempt, while hourly and many salaried nonexempt workers earn overtime by law.
Gross is the starting line, not the check. Federal and state tax, Social Security, Medicare, and benefits leave before net pay, often removing a fifth to a third.
How to use
- Enter the base hourly rate.
- Enter regular hours for the period.
- Enter overtime hours separately.
- Pick the contract multiplier and read gross.
Formula
- rate
- Base hourly pay before premiums.
- multiplier
- Premium: 1.5 federal standard, 2.0 double time.
- gross
- Total before tax and deductions.
Weekly overtime counts hours past forty in one week, not per paycheck. Daily overtime states like California add premiums past eight hours in a day.
Worked example
Example: $20 rate, 40 regular, 8 overtime at 1.5x
Hourly 20, full week plus 8 extra hours.
- Regular: 20 x 40 = $800.00.
- Overtime rate: 20 x 1.5 = $30.00 per hour.
- Overtime: 30 x 8 = $240.00.
- Gross: 800 + 240 = $1,040.00 before deductions.
Reference table
| Hourly | At 1.5x | At 2x |
|---|---|---|
| $15.00 | $180.00 | $240.00 |
| $20.00 | $240.00 | $320.00 |
| $25.00 | $300.00 | $400.00 |
| $35.00 | $420.00 | $560.00 |

Questions
What is time and a half?
1.5 times the base rate: $20 becomes $30 for overtime hours.
When does overtime start?
Past 40 hours a week federally for covered workers. Some states add daily triggers.
Do salaried workers get overtime?
Nonexempt ones do. Exempt roles above duties and salary tests do not.
Is holiday pay overtime?
Not automatically. Holiday premiums are policy, while overtime follows hours law.
How is OT taxed?
Like normal wages. Withholding may look higher on big checks but settles at filing.
Two rates in one week?
Overtime uses the weighted average rate. This tool fits single rate weeks.
