Hours Calculator
100% PrivateCalculatorsAdd up work hours from start and end times, with a break deducted and totals per entry.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
An end time at or before its start is treated as the next day, which is how overnight shifts are usually written. The break is deducted once from the total.
- 1Enter the start and end time of your first work entry.
- 2Add rows for extra segments of the day if you clocked in and out more than once.
- 3Enter the total unpaid break minutes to deduct.
- 4Read the totals before and after the break, plus decimal hours.
The gross span is 8 hours (480 minutes). After the break, the paid time is 7h 30m, which is 7.50 in decimal hours, the format most payroll systems and timesheets ask for.
- An end time at or before its start is treated as the next day, which covers overnight shifts; a full 24-hour entry is not supported as a single row.
- The break is deducted once from the total, so enter your combined break minutes across all entries.
- Rounding rules for pay (for example to the nearest quarter hour) are set by your employer and are not applied here.
Divide by 60: 45 minutes is 0.75 hours, 20 minutes is 0.33. The tool shows the decimal figure to two places alongside the clock format.
About this tool
The Hours Calculator adds up work time from start and end clock times, deducts a break, and reports both clock format and decimal hours for payroll. Add a row per shift segment, which handles split shifts and multi-part days, and overnight shifts are treated correctly as running into the next day.
