Overtime Pay Calculator
Work out overtime at time and a half, double time or your own multiplier — or enter each day's hours and apply US federal, California or custom rules to see your gross pay day by day.
How overtime pay is calculated
- Overtime rateregular rate × multiplier (1.5 for time and a half, 2 for double time)
- Gross payregular hours × rate + overtime hours × rate × 1.5 + double-time hours × rate × 2
- Effective hourly rategross pay ÷ all hours worked
- Rate from a salaryweekly salary ÷ hours the salary covers (annual ÷ 52, monthly × 12 ÷ 52)
With daily hours, each hour is paid once at the highest rate that applies. Weekly overtime is taken from straight-time hours in day order, so it lands on the days that push the week past 40.
Worked example
$20.00 an hour, working all seven days of a Monday–Sunday workweek (54 hours):
| Day | Hours | California | Federal |
|---|---|---|---|
| Mon | 8 | $160.00 | $160.00 |
| Tue | 8 | $160.00 | $160.00 |
| Wed | 8 | $160.00 | $160.00 |
| Thu | 8 | $160.00 | $160.00 |
| Fri | 8 | $160.00 | $160.00 |
| Satpast 40 h | 4 | $120.00 | $120.00 |
| Sun7th day, 7th day over 8 h | 10 | $320.00 | $300.00 |
California: 40 regular hours, 12 at 1.5× (4 past 40 on Saturday and the first 8 on the seventh day) and 2 at 2× = $1,240.00.
Federal rules only look at the week: 40 regular hours and 14 at 1.5× = $1,220.00. The same 54 hours are worth $20.00 more under California law because of the seventh-day double time.
Federal and California overtime rules
US federal (FLSA)
Non-exempt employees get at least 1.5× their regular rate for hours over 40 in a workweek. The workweek is a fixed, recurring 7-day period chosen by the employer, and each week stands alone — two weeks can't be averaged. There is no daily overtime and no federal double time.
California
1.5× for hours over 8 in a workday, over 40 in a workweek and the first 8 on a seventh consecutive workday; 2× for hours over 12 in a workday and over 8 on that seventh day. Four 10-hour days earn 8 hours of daily overtime even though the week is only 40 hours.
Not covered here
Exempt employees, California alternative workweek schedules, other states' daily rules, union contracts, and bonuses or shift differentials that raise the regular rate. Outside the US, rules differ again — the UK has no legal overtime premium, for example. Use Custom rules for your own thresholds.
The calculator treats each day you enter as one workday and the seven days as one workweek. In California a workday is any fixed 24-hour period set by the employer, so a shift that crosses its start time may split differently. Results are gross pay, not legal advice; for a pay dispute, contact the US Department of Labor's Wage and Hour Division or California's Labor Commissioner (DLSE).

Frequently asked questions
How do I calculate overtime pay?+
Multiply your regular hourly rate by the overtime multiplier and by the overtime hours, then add your regular pay. At $25.00 an hour, 40 regular hours plus 6 hours at time and a half is 40 × $25.00 + 6 × $37.50 = $1,225.00 gross.
What is time and a half and double time?+
Time and a half is 1.5 times your regular hourly rate — $30 an hour if you normally earn $20. Double time is twice your regular rate, $40 an hour in the same case. Federal law only requires time and a half; double time comes from state law such as California's, or from your contract.
How does overtime work in California?+
Under Labor Code section 510, non-exempt employees get 1.5 times their regular rate for hours over 8 in a workday, hours over 40 in a workweek, and the first 8 hours on the seventh consecutive day worked in a workweek. They get double time for hours over 12 in a workday and for hours over 8 on that seventh day.
Do daily overtime hours count toward 40 hours a week in California?+
No. Hours already paid as daily or seventh-day overtime aren't counted again toward the 40-hour weekly limit, so no hour is paid overtime twice. Five 10-hour days earn 10 hours of daily overtime and 40 regular hours — not an extra 10 hours of weekly overtime on top.
When does the seventh-day rule apply?+
Only when you work all seven days of your employer's fixed workweek. Seven days in a row that straddle two workweeks don't trigger it. On that seventh day the first 8 hours are paid at 1.5× and anything over 8 at 2×.
Is there daily overtime outside California?+
Federal law (the FLSA) has no daily overtime: only hours over 40 in a workweek count, however long a single day is. A few states add daily rules — Alaska, Colorado and Nevada, for example, under conditions that vary — and union contracts often do too. Use Custom rules to set your own thresholds.
Do salaried employees get overtime?+
Salaried employees who are non-exempt do. Their regular rate is the weekly salary divided by the hours it is meant to cover, and overtime is paid at 1.5× that rate. Employees who meet both a duties test and a minimum salary level are exempt and don't get overtime. Use "From salary" to derive the hourly rate.
Is this my take-home pay?+
No. The calculator shows gross pay before income tax, Social Security, Medicare and other deductions. Use the Paycheck Calculator to estimate take-home pay. It also isn't legal advice — check your state's labor department or your contract if you think you were underpaid.
Is anything I enter saved or sent?+
No. Everything is calculated in your browser and nothing is stored or uploaded.
