The FLSA requires 1.5× the regular rate for hours worked over 40 in a workweek. There is no federal daily overtime, no double time, and no required premium for weekends or holidays, those are state law or employer policy.

Most workers in the United States are covered by the Fair Labor Standards Act, which has a single, simple overtime rule: anything over 40 hours in a workweek is paid at one and a half times the regular rate. There is no federal daily limit, so under federal law you can work a twelve-hour day with no overtime as long as your weekly total stays at or below 40. A handful of states layer a daily rule on top. California is the clearest example: it pays time-and-a-half after eight hours in a single day and double time after twelve, regardless of the weekly total. This calculator applies the daily rule first, day by day, then checks whether any remaining straight-time hours push the weekly total past 40, so the same hour is never paid as overtime twice.
Time and a half is 1.5 times your regular hourly rate, and double time is 2 times. The words describe a multiplier, not a separate pot of money, so the tool shows each premium as its own line with the exact arithmetic. If you earn $20 an hour and work ten hours of overtime, you see 10h × $20 × 1.5 = $300 spelled out, plus the straight-time line, plus any double-time line. The total weekly pay, the overtime premium you earned on top of straight time, and your blended effective rate are summarised at the bottom so you can check a payslip in seconds.
The most common way overtime is underpaid is the regular-rate rule. The law does not let an employer base overtime on the bare hourly wage if you also receive non-discretionary bonuses, shift differentials, or commissions. Those have to be folded back into an inflated "regular rate" before the 1.5 multiplier is applied. A production bonus of a few dollars an hour can lift your true overtime rate noticeably. This calculator uses the single hourly figure you enter, so treat its result as a floor: if you get those extras, your correct overtime rate is higher, and it is worth raising with payroll.
Plenty of workplaces are more generous than the law. Some pay daily overtime even outside California, some pay double time on the seventh consecutive day, and many union contracts set their own thresholds and multipliers. The custom rule lets you enter your own overtime and double-time multipliers so you can model exactly what your agreement promises rather than the statutory floor. Set the multipliers to match your contract, fill in the daily hours, and the breakdown follows your numbers. Always confirm the result against the written policy, because consecutive-day rules and special premiums can interact in ways a single weekly view does not capture.
Overtime is the pay side of working time. For the time side, the working days calculator counts business days across a period, the holiday pay calculator handles pay for hours worked on a public holiday, and the annual leave calculator pro-rates your paid holiday entitlement. Between them they cover overtime, holiday pay, and leave from one place.
Under federal US law, overtime is 1.5 times your regular rate for every hour worked over 40 in a single workweek. Some states add daily overtime: California pays 1.5 times after 8 hours in a day and 2 times after 12. This tool splits your hours into straight, overtime, and double-time buckets and shows the formula for each.
Time and a half means 1.5 times your normal hourly rate. If you earn $20 an hour, your time-and-a-half rate is $30. It is the standard federal overtime premium for hours beyond 40 in a workweek.
Federal law does not require double time at all. California is the main state that mandates it: 2 times the regular rate after 12 hours in a workday, and after 8 hours on a seventh consecutive workday. Otherwise double time is an employer policy or union term, which you can model with the custom rule.
Legally it uses your 'regular rate', which folds non-discretionary bonuses, commissions, and shift differentials into the base. This calculator uses the hourly rate you enter, so if you receive those extras your true overtime rate may be a little higher.
