Calculate difference in time in Microsoft Excel

Let’s say that you want to find out how long it takes for an employee to complete an assembly line operation or a nurse to give insulin after a blood glucose test, or a fast food order to be processed at peak hours. There are several ways to calculate the difference between two times.

One of the easiest methods is to subtract one time from another and format the result as h:mm. When you do this your answer may show AM or PM. To correct this mistake:

1. Simply right click the cell. 2. Click **Format Cells**. 3. Make sure you are on **Custom**. Click in the **Type** box and remove the AM/PM. See the red rectangle below. 4. Click OK.

Excel – YouTube video – calculate the difference in time

YouTube video below shows how to calculate the difference in time from two cells with time in them. Example: 4:25 pm – 1:18 pm. If you go over midnight (11pm to 3am), you will end up with a lot of pound symbols. Widening the column won’t help with the pound symbols. You have to write an IF Statement which is also shown in the video.
