Hours Calculator (Time Card)
Add up work hours from start and end times with breaks, across multiple shifts. See total hours and decimal hours, plus optional pay. Runs in your browser.
Enter times in 24-hour format. A shift that ends earlier than it starts is treated as overnight (crossing midnight). Decimal hours multiply by your rate for a quick pay estimate. Everything is computed in your browser.
Add up hours from a timesheet or work day. Enter each shift's start and end time and any break, and see the total as hours-and- minutes and as decimal hours, plus an optional pay estimate. Overnight shifts are handled, and nothing is uploaded.
How to use it
No account, no upload — it all happens on your device.
Why two totals
Hours-and-minutes for people, decimal for payroll.
"7h 45m" is how we read time, but payroll and invoicing want decimal hours (7.75) so they can multiply by a rate. Mixing the two up is a common source of pay errors — this tool shows both from the same input so you never have to convert by hand.
Tips
- Log unpaid breaks.Put lunch in the break column so it's subtracted from the shift.
- Split odd days into shifts. Add a second row for a split shift or a return-to-work evening session.
- Round per your employer's rules. Some round to the nearest quarter hour — the decimal total makes that easy to spot.
