## How to Calculate Total Hours in Microsoft Excel

Calculating total hours in Microsoft Excel is a straightforward process that helps you track and manage time accurately. Follow the steps below to learn how to sum hours effectively in your worksheets.

• ### Step 1. Enter Your Time Data

Begin by entering your start and end times in separate cells in a column format. For example, enter start times in column A and end times in column B.

• ### Step 2. Calculate the Time Difference

In a new column, calculate the difference between the start and end times using a formula. Click on the cell where you want the total hours to appear and enter “=B2-A2,” where “B2” is the end time and “A2” is the start time. Press “Enter” to see the result.

• ### Step 3. Format the Cells as ‘Time’

To ensure the results display correctly, format the cells containing the calculated time difference as “Time.” Highlight the cells with the formula, right-click, and select “Format Cells.” Choose “Time” from the list and select the desired time format.

• ### Step 4. Sum the Total Hours

To get the total hours worked, use the SUM function. In a new cell, enter “=SUM(C2:C10)” if your calculated time differences are in column C, from rows 2 to 10. Press “Enter” to see the total hours.

• ### Step 5. Adjust for Hours Over 24

If the total exceeds 24 hours, adjust the format to display it correctly. Right-click on the cell with the total, select “Format Cells,” choose “Custom,” and enter “[h]:mm” to display the total hours correctly even if it exceeds 24 hours.
