If the end time is earlier than the start time, the shift is treated as running past midnight. Overtime follows the federal 40-hour weekly rule; some states, such as California, also require daily overtime.
How to use
- Enter a start time and end time for each day you worked. Leave days off blank.
- Enter unpaid break minutes for each day, such as 30 for a lunch break.
- Check the hours for each day and the weekly total in hours:minutes and decimal hours.
- Optionally enter your hourly rate to estimate gross pay, including 1.5× overtime after 40 hours.
How the calculator works
For each day, the calculator subtracts the start time from the end time and then removes the unpaid break minutes. If the end time is earlier than the start time, it adds 24 hours, because the shift crossed midnight. The daily results are added together to give the weekly total.
Totals are shown two ways. Hours and minutes (for example 38:45) is how time clocks and schedules display time. Decimal hours (38.75) is what payroll uses, because it can be multiplied directly by an hourly rate. To convert, divide the minutes by 60: 15 minutes is 0.25 hours, 30 minutes is 0.5, and 45 minutes is 0.75.
Overtime and gross pay
If you enter an hourly rate, the calculator splits the week into regular hours (up to 40) and overtime hours (anything above 40). Regular hours are paid at your rate and overtime hours at 1.5 times your rate, which is the minimum required by the Fair Labor Standards Act for non-exempt employees.
For example, 45 hours at $20 per hour is 40 × $20 = $800 of regular pay plus 5 × $30 = $150 of overtime, for a gross total of $950.
Overtime is calculated per workweek, a fixed period of seven consecutive days set by your employer. Hours cannot be averaged across two weeks, so 30 hours one week and 50 the next still earns 10 hours of overtime in the second week. Some states add daily overtime rules; California, for instance, requires overtime after 8 hours in a workday and double time after 12. Salaried employees who are classified as exempt do not earn overtime at all.
Checking your paycheck
A weekly time card is the simplest way to check that a paycheck matches the hours you actually worked. Compare the decimal total with the hours listed on your pay stub. Small differences can come from rounding: many employers round clock-in and clock-out times to the nearest 5, 6 or 15 minutes, which federal rules allow as long as it averages out fairly over time.
Tips for accurate entries
- Use the 24-hour clock or AM/PM as your device’s time picker shows; the result is the same.
- Record the break you actually took, not the one on the schedule.
- If you worked two separate shifts on the same day, add the gap between them as break time.
- Use the Clear all button to start a new week, or Reset to fill a standard 9:00 to 5:30 week with a 30-minute lunch.

Frequently asked questions
- How do I convert minutes to decimal hours?
- Divide the minutes by 60. For example, 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 hours. Payroll systems multiply your hourly rate by decimal hours, so 7:45 at $20 per hour is 7.75 × $20 = $155.
- What if my shift goes past midnight?
- Enter the times as they appear on the clock, for example 10:00 PM to 6:00 AM. When the end time is earlier than the start time, the calculator treats the shift as ending the next day and counts 8 hours.
- Are breaks paid?
- Under federal law, short rest breaks of about 5 to 20 minutes are counted as paid work time, while bona fide meal periods of 30 minutes or more, when you are fully relieved of duty, are usually unpaid. Enter only unpaid break time in the break column. Some states have their own break rules.
- When does overtime start?
- The federal Fair Labor Standards Act requires overtime pay of at least 1.5 times the regular rate for hours over 40 in a workweek for non-exempt employees. A few states, such as California, also require overtime for hours over 8 in a single day, which this calculator does not apply.
- Does it include taxes?
- No. The pay shown is gross pay before federal and state income tax, Social Security, Medicare and other deductions.
- Is my time card saved or uploaded?
- No. Everything is calculated in your browser and nothing is sent to a server. Copy or note the totals before you close the page.
