How to Subtract Times in Excel

Welcome to this Excel blog post, where we will be discussing how to subtract times in Excel. As you know, Microsoft Excel is a powerful tool that is used by many professionals for different purposes. One of the useful features of Excel is that it can perform various calculations, including subtracting times. Whether you are a business analyst, a student, or a researcher, you might need to subtract one time from another to arrive at a value. In this post, we will show you how to do this efficiently using Excel.

Step 1: Enter the Times You Want to Subtract

The first step is to enter the two times that you want to subtract in Excel. Make sure that you enter the times in a separate cell for each time. You can enter the time manually using the formatting 00:00 or use the keyboard shortcut Ctrl + Shift + ; to enter the current time.

Step 2: Format the Cells as Time

The next step is to format the cells that contain the times as time. To do this, select the cells that contain the time values, right-click and select “Format Cells”. In the Format Cells dialog box, select “Time” in the Category list and then choose the appropriate time format in the Type list. Choose the format that displays the hours, minutes, and seconds, if necessary.

Step 3: Subtract the Times

Now that you have entered the times and formatted the cells correctly, it’s time to subtract them. In a new cell, enter the formula that subtracts the two times. The formula should look like this: =Time1 – Time2, where Time1 and Time2 are the cells that contain the times you want to subtract.

Example:

If you want to subtract 9:30 AM from 2:45 PM, the formula would be: =2:45 PM – 9:30 AM.

Step 4: Format the Cell that Contains the Result

The last step is to format the cell that contains the result of the subtraction. Select the cell that contains the result, right-click and choose “Format Cells”. In the Format Cells dialog box, select “Time” in the Category list and then choose the appropriate time format in the Type list. Choose the format that displays the hours, minutes, and seconds, if necessary.

Subtracting times in Excel is a simple process that can be done in just a few steps. By following the steps outlined in this post, you can subtract times in Excel with ease. This feature of Excel is incredibly useful for anyone who needs to calculate time differences for various purposes. We hope that this post has been helpful to you and that you can apply this knowledge in your work or personal life.

Dealing with Negative Time

When you subtract times in Excel, you might end up with a negative time value. This happens when the second time is greater than the first time. Excel displays negative time values as #########, which means that the cell is not wide enough to display the result. You can change the format of the cell to display negative time values properly. Select the cell that contains the result, right-click and choose “Format Cells”. In the Format Cells dialog box, select “Time” in the Category list and choose the appropriate time format in the Type list that displays negative time values properly.

Adding Time Values

You can also add time values in Excel. The process is similar to subtracting time, but instead of using the minus sign (-), you use the plus sign (+). The formula to add time values in Excel is =Time1 + Time2, where Time1 and Time2 are the cells that contain the times you want to add.

Example:

If you want to add 2 hours and 30 minutes to 1:45 PM, the formula would be: =1:45 PM + 2:30:00.

Using Time Duration Formats

If you are dealing with time differences that are more than 24 hours, Excel can display the time duration in a custom format such as [h]:mm:ss or [hh]:mm:ss. The square brackets around the h or hh make Excel display the number of hours beyond 24 hours.

Example:

If you want to calculate the time duration between 14:00 on Monday and 10:00 AM on Wednesday, the formula would be: =(10:00:00 AM – 2:00:00 PM) + (24 * 2) = 46:00:00. The result will be displayed in the format of 46 hours, 0 minutes, and 0 seconds.

We have also provided some additional information such as dealing with negative time values, adding time values, and using time duration formats.
