What is Work Hours?
Work hours are the total amount of time you spend working during a shift after deducting unpaid breaks. They can be measured in hours and minutes or converted into decimal hours for payroll and timesheet calculations.
Knowing your actual work hours helps you keep accurate records, estimate your earnings, and make sure you're paid correctly for every shift you complete.

Work Hours Formula & Calculation Method
This calculator measures the time between your start time and end time, subtracts any unpaid break, and then converts the result into hours and minutes, decimal hours, and total minutes. If you enter your hourly pay rate, it also calculates your estimated earnings for the shift.
Work Hours = (End Time − Start Time) − Break Time
Decimal Hours = Total Minutes ÷ 60
Total Pay = Decimal Hours × Hourly Pay
Example:
Suppose you start work at 9:00 AM, finish at 5:30 PM, take a 30-minute break, and earn $20 per hour. Your total shift length is 8 hours 30 minutes. After subtracting the break, your actual work time becomes 8 hours (480 minutes). The calculator will display the following results:
- Total Time: 8h 0m
- Decimal Hours: 8.00
- Minutes: 480
- Total Pay: $160.00
