About the Overtime Calculator
This overtime calculator works out what extra hours are worth. Enter your regular hourly rate, the regular hours in the pay period, and any overtime and double-time hours; it returns overtime pay, total gross pay, the overtime rate itself and your blended effective hourly rate.
Under the US Fair Labor Standards Act (FLSA), non-exempt employees must be paid at least 1.5 times their regular rate for hours over 40 in a workweek. Some states (such as California) and many union contracts also require daily overtime or double time. Choose the multiplier that applies to you — 1.5× is standard, but you can model 1.25× or 2× as well.
Use it to check a paycheck, decide whether picking up an extra shift is worth it, or estimate how much overtime adds over a year. Results are gross pay before taxes; overtime is taxed like any other wages, although for 2025 through 2028 the FLSA-required premium part (the “half” in time and a half) may qualify for the federal overtime deduction of up to $12,500 ($25,000 joint) when you file.
With the default inputs, the total gross pay for the period is $1,300.00. Change any value above to recalculate instantly.
How to use the overtime calculator
- 1Enter your regular hourly rate.
- 2Enter regular hours for the pay period (40 per week under the FLSA).
- 3Enter overtime hours and choose the multiplier — 1.5× is standard.
- 4Add any double-time hours your state or contract requires.
- 5Pick the pay period to see what the overtime is worth over a year.
Formula and method
Regular pay is the hourly rate times regular hours. Overtime pay is the overtime hours times the overtime rate, which is the regular rate multiplied by the overtime multiplier (1.5 for time and a half). Double-time hours are paid at twice the regular rate. The effective hourly rate divides total pay by all hours worked.
Under the FLSA the “regular rate” must include most non-discretionary bonuses, shift differentials and commissions, not just the base wage, so overtime can be worth slightly more than this simple calculation if you earn those. Overtime is measured per workweek; averaging hours across two weeks is not allowed.

Worked examples
8 hours of time and a half at $25/hour
The overtime rate is $25 × 1.5 = $37.50, so 8 overtime hours pay $300 on top of $1,000 regular pay, for $1,300. Repeated every week, that is $15,600 of overtime a year.
Overtime plus double time at $32/hour
40 regular hours pay $1,280; 10 hours at $48 add $480; 4 double-time hours at $64 add $256. Total pay is $2,016 for 54 hours — an effective $37.33 per hour.
Biweekly period with 12 overtime hours
80 regular hours at $20 pay $1,600 and 12 overtime hours at $30 add $360, so the paycheck is $1,960 gross. Twenty-six such periods add $9,360 of overtime a year.
Frequently asked questions
How do I calculate time and a half?+
Multiply your regular hourly rate by 1.5 to get the overtime rate, then multiply by overtime hours. At $20 an hour, time and a half is $30, so 5 overtime hours pay $150.
Who is entitled to overtime pay?+
Under the FLSA, non-exempt employees must get at least 1.5× their regular rate for hours over 40 in a workweek. Many salaried professional, executive and administrative employees are exempt if they meet the salary and duties tests.
What is double time?+
Double time is pay at twice the regular rate. Federal law does not require it, but California requires it for hours over 12 in a workday and for hours over 8 on the seventh consecutive workday of a workweek, and some union contracts require it for holidays or long shifts.
Is overtime taxed at a higher rate?+
No. Overtime is ordinary wages and is taxed at the same rates, though a larger paycheck can have more withheld. From 2025 through 2028, eligible workers may deduct the FLSA-required premium part of qualified overtime (up to $12,500, or $25,000 joint, phasing out above $150,000 of modified AGI or $300,000 joint) on their federal return, whether or not they itemize.
Can my employer average hours over two weeks?+
No. FLSA overtime is based on each 168-hour workweek on its own. Working 50 hours one week and 30 the next still earns 10 overtime hours, even though the two-week total is 80.
