Our 45 minute lunch break calculator tool is designed to help employees and employers accurately determine working hours for a standard 45-minute lunch break.
Consider an employee who clocks in at 8:00 AM and clocks out at 5:00 PM. Without accounting for the lunch break, it might appear that they worked 9 hours. By using the forty five minute lunch break calculator, we can determine that their actual working time is 8 hours and 15 minutes.

45 Minute Lunch Break Calculation Formula
Total Working Hours = Total Time at Work – 45 minutes
To apply this formula effectively, follow these steps:
- Determine the total time spent at work (from clock-in to clock-out).
- Convert this time to minutes for easier calculation.
- Subtract 45 minutes for the lunch break.
- Convert the result back to hours and minutes.
An employee works from 9:00 AM to 6:00 PM.
Total time at work: 9 hours (540 minutes)
Subtract lunch break: 540 – 45 = 495 minutes
Convert back to hours and minutes: 8 hours and 15 minutes
The employee’s actual working time is 8 hours and 15 minutes.
How do you calculate hours worked including lunch break?
- Determine the total time from clock-in to clock-out.
- Include the lunch break in your calculation.
The formula becomes:
Total Hours = Clock-out Time - Clock-in TimeAn employee clocks in at 8:30 AM and clocks out at 5:30 PM.
Calculate the difference: 5:30 PM – 8:30 AM = 9 hours
This total includes the 45-minute lunch break
The employee’s total time at work is 9 hours, with 8 hours and 15 minutes of actual work time.
| Clock-In Time | Clock-Out Time | Total Time | Break Duration | Working Time (after break) |
|---|---|---|---|---|
| 8:00 AM | 4:30 PM | 8h 30m | 1 hour | 7 hours and 30 minutes |
| 9:00 AM | 5:30 PM | 8h 30m | 30 minutes | 8 hours |
| 10:00 AM | 6:30 PM | 8h 30m | 45 minutes | 7 hours and 45 minutes |
| 11:00 AM | 7:30 PM | 8h 30m | 15 minutes | 8 hours and 15 minutes |
How many hours is 9 to 5:30 with a 45-minute break?
Total time from 9:00 AM to 5:30 PM = 8 hours and 30 minutes (510 minutes)
Subtract the 45-minute lunch break: 510 – 45 = 465 minutes
Convert back to hours and minutes: 7 hours and 45 minutes
An employee working from 9:00 AM to 5:30 PM with a 45-minute lunch break has an actual working time of 7 hours and 45 minutes.
