Work Hours Calculator

Enter your clock-in and clock-out times plus your break, and instantly see exactly how many hours you worked — as a decimal, as hours and minutes, and with any overtime beyond 8 hours broken out separately. Night shifts that cross midnight are handled automatically.



How to Use the Work Hours Calculator

  1. Enter the time you started work in the Clock in field.
  2. Enter the time you finished in the Clock out field.
  3. Type your unpaid break in minutes (lunch, for example). Leave it at 0 if you had none.
  4. Press Calculate to see your total as a decimal (for timesheets), as hours and minutes, and any overtime beyond a standard 8-hour day.

Practical example

You clock in at 08:15, clock out at 17:45, and take a 45-minute lunch. The calculator shows 8.75 hours (8h 45m) with 0h 45m of overtime. If you fill in timesheets that want decimals, you can copy 8.75 straight across; if your manager wants hours and minutes, use 8h 45m. A night shift from 22:00 to 06:00 is understood as crossing midnight — no need to split it into two entries.

Freelancers billing by the hour use the decimal output directly on invoices — 6.5 hours at your rate, no mental division. If you work irregular shifts across a week, run each day through the calculator and add the decimals; the consistent format makes weekly totals trivial.

Key features and benefits

  • Decimal and hh:mm output: get both formats at once, whichever your timesheet needs.
  • Automatic overtime: anything beyond 8 hours is broken out separately, so extra pay is easy to spot.
  • Overnight shifts: clocking out earlier than you clocked in is treated as the next day.
  • Break deduction: unpaid breaks are subtracted before the total, matching how most payroll works.
  • Input validation: impossible entries — like a break longer than the shift — show a clear message instead of a nonsense answer.
  • Instant results: no page reloads, no accounts, no spreadsheets to open.

Limitations

Overtime is fixed at anything beyond 8 hours per day; the tool does not handle weekly overtime rules, double-time, weekend rates, or country-specific labour thresholds. It assumes a single continuous shift — split shifts need to be calculated in two passes. Results are for guidance only and are not payroll or legal advice; always confirm with your employer’s official timekeeping system.
