Hours Calculator (Time Card)

Enter your start time, end time, and any unpaid break minutes. The calculator subtracts the break from the total elapsed time and shows your result in both hours-and-minutes (e.g., 8:30) and decimal hours (e.g., 8.5). It handles overnight shifts automatically.

Decimal hours express your total work time as a single number instead of hours and minutes. For example, 8 hours 30 minutes equals 8.5 decimal hours because 30 minutes is 0.5 of an hour. Most payroll systems and timesheets use decimal hours for calculations.

When the end time is earlier than the start time, the calculator assumes the shift crossed midnight and adds 24 hours. For example, 10:00 PM to 6:00 AM returns 8 clock hours. The tool has no date or timezone input, so it does not model daylight saving time. If start and end are identical, the result is 0 hours, not 24.

Unpaid breaks (like a 30-minute lunch) should not count as worked time. Enter the unpaid break duration in minutes and the calculator deducts it automatically. If your break time is longer than your shift duration, the calculator will not return a result, since worked time cannot be negative.

Multiply decimal hours by your hourly rate. At $20/hr for 8.5 hours, gross straight-time pay is $170. Under the FLSA, covered nonexempt employees generally earn at least 1.5 times their regular rate for hours above 40 in a workweek. The regular rate can differ from base pay, and state or contract rules may add other overtime requirements.
