Formula Used

The calculator uses the following formula to calculate your work hours:

Total Work Hours = (End Time - Start Time) - Break Duration Net Hours = Total Work Hours - Break Duration

Where:

Start Time = Your workday start time
End Time = Your workday end time
Break Duration = Length of your lunch break

Worked Example

Let's look at an example to see how the calculator works:

Suppose you start work at 9:00 AM and finish at 5:00 PM, with a 1-hour lunch break. Here's how the calculation would work:

Input	Value
Start Time	9:00 AM
End Time	5:00 PM
Break Duration	1 hour

Using the formula:

Total Work Hours = (5:00 PM - 9:00 AM) - 1 hour Total Work Hours = 8 hours - 1 hour = 7 hours Net Hours = 7 hours - 1 hour = 6 hours

So in this example, you would have 7 total work hours and 6 net hours after accounting for your lunch break.

Interpreting Your Results

When you use this timesheet calculator, you'll get two key results:

Total Work Hours: This shows the total time between your start and end times
Net Hours: This shows your actual productive hours after accounting for breaks

These results help you understand:

How much time you actually spent working
The impact of breaks on your productivity
Whether you're meeting your expected work hours

Remember that the calculator assumes your break is a single, continuous period. If you take multiple short breaks throughout the day, you may need to adjust the break duration accordingly.
