How to use the time card calculator
- Pick your overtime rule — federal for most states, or California, Alaska, Nevada or Colorado daily rules.
- Enter time in and time out for each day you worked. Use the ↓ button to copy a day to the rest of the week.
- Add unpaid break minutes, such as a 30-minute lunch. Turn on "second in/out" if you clock out for lunch or work a split shift.
- Add an hourly rate to see gross pay, including overtime at 1.5× and double time at 2×.
- Download a PDF time card with signature lines, export CSV for payroll, or add more employees.
How to calculate hours worked by hand
For each day: time out − time in − unpaid break = hours worked. Then add the days.
- Convert both times to 24-hour time: 8:45 AM = 08:45, 5:15 PM = 17:15.
- Subtract: 17:15 − 08:45 = 8 hours 30 minutes.
- Take off the unpaid lunch: 8:30 − 0:30 = 8 hours 0 minutes.
- Convert minutes to decimals for payroll (minutes ÷ 60): 8:00 = 8.00 hours.
For a shift that crosses midnight, add 24 hours to the time out first: 19:00 to 07:00 is (07:00 + 24:00) − 19:00 = 12 hours. Not sure of a 24-hour time? Use the military time converter.
Minutes to decimal hours chart
Payroll uses decimal hours. Divide minutes by 60, or use this chart:

Overtime rules the calculator uses
| Rule | Daily overtime | Weekly overtime |
|---|---|---|
| Federal (FLSA), most states | None | 1.5× over 40 hours |
| California | 1.5× over 8 h; 2× over 12 h; 7th consecutive day: 1.5× first 8 h, 2× after | 1.5× over 40 hours |
| Alaska | 1.5× over 8 h (employers with 4+ employees) | 1.5× over 40 hours |
| Nevada | 1.5× over 8 h in 24 hours for employees earning under 1.5× minimum wage | 1.5× over 40 hours |
| Colorado | 1.5× over 12 h in a workday | 1.5× over 40 hours |
Hours are never counted twice: weekly overtime only applies to regular hours left after daily overtime. Exempt (salaried) employees and some industries have different rules — see the U.S. Department of Labor and your state labor department. For more detail, use the overtime calculator.
Breaks and rounding
Breaks: federal law does not require breaks, but short rest breaks of 5–20 minutes must be paid. Meal periods of 30 minutes or more can be unpaid when you are fully relieved of duty. Many states (including California, Oregon and Washington) require meal and rest breaks.
Rounding: employers may round punches to the nearest 5, 6 or 15 minutes if rounding is neutral over time (29 CFR 785.48). With 15-minute rounding, 1–7 minutes round down and 8–14 round up.

Frequently asked questions
How do I calculate hours worked on a time card?
For each day, subtract the time in from the time out and take away any unpaid break. Convert the minutes to decimal hours (divide by 60), then add the days together. Example: 8:45 AM to 5:15 PM with a 30-minute lunch is 8 hours 30 minutes minus 30 minutes = 8.00 hours.
How do I convert minutes to decimal hours?
Divide the minutes by 60. 15 minutes = 0.25 hours, 30 minutes = 0.5, 45 minutes = 0.75. So 7 hours 20 minutes is 7.33 hours.
How does the calculator handle overnight shifts?
If the time out is earlier than the time in, the shift is treated as crossing midnight. A 7:00 PM to 7:00 AM shift counts as 12 hours. A shift that starts and ends at the same time counts as 24 hours.
When does overtime start?
Under federal law (FLSA), non-exempt employees earn at least 1.5 times their regular rate for hours over 40 in a workweek. Some states add daily overtime — California pays 1.5× after 8 hours in a day and 2× after 12. Choose your rule in the calculator.
Are lunch breaks paid?
Federal law does not require breaks. Short breaks (usually 5 to 20 minutes) must be paid if given. Meal breaks of 30 minutes or more can be unpaid if the employee is fully relieved from duty. Enter only unpaid break minutes in the calculator.
Is rounding time punches legal?
Under federal rules, employers may round to the nearest 5, 6 or 15 minutes if the practice is neutral and, over time, does not undercount the hours employees actually worked (29 CFR 785.48). Rounding to the nearest 15 minutes is often called the 7-minute rule.
