Formula Explained

The calculator uses this simple formula to determine your net hours worked:

Net Hours = (End Time - Start Time) - Lunch Break

Lunch Break is in hours (e.g., 0.5 for 30 minutes)

The calculator handles time calculations accurately, including overnight shifts if needed.

Worked Example

Let's say you worked from 8:00 AM to 5:00 PM with a 30-minute lunch break. Here's how the calculation works:

Net Hours = (17:00 - 08:00) - 0.5 = 9 hours - 0.5 hours = 8.5 hours

This means you worked 8.5 net hours after accounting for your lunch break.

Excel Format Guide

For Excel users, here's how to format your timesheet to match the calculator's results:

Create columns for Start Time, End Time, and Lunch Break
Use the TIMEVALUE function to convert text times to Excel time values
Calculate net hours with: =TIMEVALUE(End Time)-TIMEVALUE(Start Time)-Lunch Break
Format the result as a decimal number for hours

Tip: Use Excel's TIME function to create time values directly in your sheet.
