Hours Calculator – Hours Worked and Time Card Calculator

How to use the hours calculator

For one shift:

1. Choose One shift.
2. Enter the start time and end time.
3. Enter the unpaid break in minutes.
4. Optionally enter your hourly pay.

For a timesheet:

1. Choose A whole timesheet.
2. Type one line per day, like Mon 9:00-17:30 30.

You’ll see the total in hours and minutes, the same total in decimal hours, a day-by-day table and your pay before tax.

How the hours are worked out

If the end time is earlier than the start time, 24 hours are added so overnight shifts work.

Worked example: a week’s timesheet

Total = 38 hours 15 minutes = 38.25 hours. At $20 an hour, that is $765 before tax.

Minutes to decimal hours

A common mistake is to write 7 hours 30 minutes as 7.30 — it is 7.5.

Tips for accurate time cards

• Record times as you go rather than from memory at the end of the week.
• Use 24-hour times or always add am/pm to avoid mix-ups.
• Round consistently if your employer rounds to the nearest 5, 10 or 15 minutes.
• Check overtime rules. In the US, many hourly employees must be paid 1.5 times their rate for hours over 40 in a week; other countries have their own rules.
• Keep a copy of your timesheets in case of pay disputes.

Rounding rules

Many employers round clock-in and clock-out times. A common US practice rounds to the nearest quarter hour, so 8:07 becomes 8:00 and 8:08 becomes 8:15. Rounding has to be neutral over time — it shouldn’t always favour the employer. If your pay looks short, compare your own records with the rounded times on your payslip.

Who uses an hours calculator

Hourly workers checking their pay, freelancers billing clients, managers approving timesheets, small businesses running payroll and students tracking study or volunteering hours all use it.
