What Is a Timesheet Calculator?

How a Timesheet Calculator Works
A timesheet calculator works by calculating daily hours and then adding them together for a total.

Weekly Work Hours Formula
The formula behind a timesheet calculator is simple:
Total Weekly Hours = Sum of Daily Hours Worked
Each daily total is calculated using:
Daily Hours = End Time − Start Time − Breaks
How to Use a Timesheet Calculator Step by Step
1. Enter Daily Start and End Times
Input the time you started and finished work for each day.
2. Add Break Time
Enter any unpaid breaks so your total reflects actual worked hours.
3. Calculate Daily Hours
The calculator determines the total hours worked each day.
4. Add Weekly Totals
The tool adds all daily hours together to give you your weekly total.
Example of a Weekly Timesheet
Here’s a simple example:
- Monday: 8 hours
- Tuesday: 7.5 hours
- Wednesday: 8 hours
- Thursday: 8.5 hours
- Friday: 8 hours
Total weekly hours = 40 hours
