How this hours calculator works
- 01Enter the start and end time for each day you worked.
- 02Type any unpaid break in minutes. It comes off that day's hours.
- 03Add your hourly rate if you want gross pay. Overtime over 40 hours in a week is paid at 1.5x.
- 04Print the time card or copy the totals into your timesheet.
A time card calculator that gets the week right
Totals come in two forms. Hours and minutes (7:45) are what you see on a clock. Decimal hours (7.75) are what payroll software uses. This work hours calculator shows both, so nothing gets rounded the wrong way.
Overtime is counted per workweek, not per pay period. On a two-week time card, 45 hours in week one and 35 in week two is 5 hours of overtime, even though the period adds up to 80. Many employee hours calculators miss this.
Hours calculator questions
- How do I calculate hours worked?
- Subtract the start time from the end time, then take off any unpaid break. 9:00 AM to 5:30 PM with a 30-minute lunch is 8 hours. This calculator does that for each day and adds up the week.
- Does this count overnight shifts?
- Yes. If the end time is earlier than the start time, the shift is counted as ending the next day. 10:00 PM to 6:00 AM is 8 hours.
- How is overtime calculated?
- Under US federal law, hours over 40 in one workweek are paid at 1.5 times the regular rate. The calculator applies that per week. Some states, such as California, also pay overtime after 8 hours in a day. Check your state rules if that applies to you.
- What is the difference between 7:30 and 7.5 hours?
- 7:30 is 7 hours and 30 minutes. 7.5 is the same time written as a decimal. Payroll uses decimals, so 7:45 becomes 7.75, not 7.45. The totals show both.
- Is this a timesheet calculator too?
- Yes. A timesheet, a time card and a work hours calculator all do the same job: add up time between clock-in and clock-out, minus breaks. Print or copy the result and attach it to your timesheet.
- Is my data saved anywhere?
- No. Everything is calculated in your browser. Nothing is sent to a server, and there is no account. Your week stays on the page until you clear it or close the tab.
