Calculating worked hours accurately is essential for both employees and employers to ensure fair compensation and compliance with labor regulations. This calculator helps you determine the exact duration of a shift by subtracting unpaid breaks from the total time elapsed between your "clock-in" and "clock-out" times.
How to Calculate Worked Hours Manually
To calculate your hours manually, follow these steps:
Convert to 24-hour clock: If you are using 12-hour AM/PM time, convert it to military time (e.g., 1:00 PM becomes 13:00).
Subtract the Start Time from the End Time: If the end time is earlier than the start time (overnight shifts), add 24 hours to the end time.
Deduct Breaks: Subtract any unpaid break time (usually in minutes) from the total.
Convert Minutes to Decimals: Divide the remaining minutes by 60 to get the decimal format used for payroll.
Decimal Hours Conversion Table
Payroll systems often require hours in decimal format rather than minutes. Here is a quick reference guide:
Minutes
Decimal Hour
15 Minutes
0.25
30 Minutes
0.50
45 Minutes
0.75
60 Minutes
1.00
Example Calculation
Suppose you started work at 8:15 AM and finished at 5:45 PM with a 45-minute lunch break.
