Overtime calculator

Enter the hours you worked each day. The calculator splits them into regular, time-and-a-half and double-time hours and shows your gross pay for the week.

How overtime is calculated

Under the federal Fair Labor Standards Act, most hourly workers earn at least 1.5 times their regular rate for every hour over 40 in a workweek. Federal law counts the week, not the day: a 12-hour shift is not overtime by itself unless the week goes over 40.

Some states add daily overtime:

• California: 1.5× after 8 hours in a day and for the first 8 hours on the seventh day in a row of the workweek; 2× after 12 hours in a day and after 8 hours on that seventh day.
• Alaska: 1.5× after 8 hours in a day or 40 in a week.
• Colorado: 1.5× after 12 hours in a day, 12 hours in a row, or 40 in a week.

An hour is only counted as overtime once. If a California shift is already paid at 1.5× for running past 8 hours, those hours are not added again to the weekly 40.

Questions

How do I calculate time and a half?

Multiply your hourly rate by 1.5. At $20 an hour, overtime pays $30 an hour. Five overtime hours add $150 to the week.

Is overtime after 8 hours or 40 hours?

Federal law uses 40 hours in a workweek. California, Alaska and a few other states also pay overtime after 8 hours in one day. Choose your rule in the calculator above.

Does a two-week pay period change overtime?

No. Overtime is worked out one workweek at a time. Working 30 hours one week and 50 the next means 10 overtime hours, even though the two weeks average 40.

What is the overtime premium?

It is the extra half on top of your regular rate. At $20 an hour the premium is $10 for each overtime hour. For tax years 2025 to 2028, the US "no tax on overtime" deduction applies to this premium part, up to a yearly limit.
