30 Minute Lunch Break Formula
The formula for calculating work hours with a thirty-minute lunch break is straightforward:
Total Work Hours = (End Time - Start Time) - 0.5 hoursThis formula can be broken down into three steps:
- Calculate the total elapsed time from start to end
- Subtract 30 minutes (0.5 hours) for the lunch break
- Round the result to the nearest quarter-hour if necessary
Suppose an employee works from 8:00 AM to 4:30 PM.
- Total elapsed time: 4:30 PM – 8:00 AM = 8.5 hours
- Subtract lunch break: 8.5 hours – 0.5 hours = 8 hours
- Result: 8 hours worked
How to calculate 30 minute lunch break?
