Overtime calculator: how much overtime did you earn?
Type the hours you worked each day and your hourly rate. You get regular, overtime and double time hours and pay under your state's rules, next to what the same week pays under every other rule set.
How overtime is calculated
Overtime pay is 1.5 times your regular rate for each overtime hour. Which hours count as overtime depends on where you work.
- Federal rule (most states): every hour over 40 in a workweek. A 12-hour day alone is not overtime.
- California: hours over 8 in a day and over 40 in a week are overtime; hours over 12 in a day are double time.
- Alaska: hours over 8 in a day or 40 in a week, for employers with 4 or more employees.
- Nevada: hours over 40 in a week, and over 8 in a day for workers paid less than 1.5 times the minimum wage ($18.00 an hour).
- Colorado: hours over 12 in a day or 40 in a week.
Each overtime hour is counted once. In California, a 10-hour day already has 2 overtime hours; those 2 hours do not count again toward the 40 hour weekly limit.
Example: four long days, no weekly overtime
Tom works 9.5 hours Monday to Thursday and nothing else. That is 38 hours. Under the federal rule there is no overtime, because the week is under 40.
In California the same week has 1.5 hours of overtime each day, 6 hours in total. At $20 an hour, federal rules pay $760. California rules pay 32 x $20 + 6 x $30 = $820. Federal rules alone would underpay Tom $60. Type 9.5 into the first four days above to see it.
Daily overtime rules by state
| Rules | Daily overtime | Double time | Weekly overtime |
|---|---|---|---|
| Federal (FLSA) | None | None | Over 40 |
| California | Over 8 | Over 12 a day; over 8 on the 7th day in a row | Over 40 |
| Alaska | Over 8 | None | Over 40 |
| Nevada | Over 8, if paid under $18.00 an hour | None | Over 40 |
| Colorado | Over 12 | None | Over 40 |
Most other states follow the federal 40 hour rule. A few have rules for particular jobs or a 7th day of work; check your state labor department if you are not sure. Colorado also counts hours over 12 in a row that run across two workdays; the calculator uses the workday rule.
California's 7th day rule
If you work all 7 days of one workweek in California, the 7th day is special. Its first 8 hours are overtime at 1.5 times your rate, and anything over 8 hours is double time. Six days in a row, or seven days split across two workweeks, does not trigger it. The calculator applies it when all seven days above have hours.
A workweek is fixed, and weeks are never averaged
Federal law counts overtime per workweek: a fixed run of 7 days that the employer picks, like Sunday to Saturday (29 CFR 778.105). It does not have to match the calendar week or the pay period.
Two weeks are never averaged. If you are paid every two weeks and work 50 hours in the first week and 30 in the second, you earned 10 hours of overtime, even though the total is 80. The timesheet calculator adds up both weeks of a biweekly pay period this way.
What the regular rate includes
Overtime is 1.5 times the regular rate, and the regular rate is more than the hourly wage when there is other pay that depends on the work. Shift differentials and bonuses promised for attendance or output count. Gifts, paid time off and discretionary bonuses do not. This calculator uses the rate you type, so if you had such pay, the true overtime is a little higher.
