If you’re struggling to subtract time values in Excel, you’re not alone. The good news? You can easily learn how to subtract time with this simple step-by-step guide. Get ready to do the math with confidence!

## How to Subtract Time in Excel: A Comprehensive Guide

Have you ever worked with Excel? If so, you might have come across the need to subtract time. Examples include figuring out the total time for a project or the duration of an activity. Good news: It’s easy to subtract time in Excel! We’ll explain how in this comprehensive guide.

To subtract time in Excel, you should understand how it stores time values. It’s as a decimal, with 1 being full 24 hrs in a day, 0.5 is 12 hrs, 0.25 is 6 hrs, and so on. To subtract time values, we subtract the decimal values. Example: To subtract 2 hrs from 4 hrs, subtract 0.083 (2 hrs/24 hrs) from 0.167 (4 hrs/24 hrs) to get a result of 0.084 (2 hrs).

You can use a formula or function to subtract time in Excel. The most common one is “**MINUS**“, which subtracts one time value from another. You can also use “**SUM**” by adding a negative time value. Other functions like “**NETWORKDAYS**” can subtract workdays or weekdays from a date.

Here are 3 tips to help you subtract time in Excel more easily:

- Use the 24-hour clock format when entering time values to avoid errors and confusion. For instance, 2:30 PM should be entered as 14:30.
- Format cells with time values properly. Options: “h:mm AM/PM” or “h:mm:ss”.
- Select multiple cells you want to subtract time values from using the “CTRL” key. Then, enter the formula or function once, and Excel will automatically subtract the values from all chosen cells.

### Customize Cell Formatting

**Customizing cell formatting is a must-do** when working with Excel. It can help make data stand out and be easier to read. Plus, it’s essential for tasks like subtracting time in Excel. Here’s how you do it:

- Highlight the cells you want to customize.
- Right-click and select “format cells” from the drop-down menu.
- In the “Format Cells” dialog box, select “Number.”
- Choose one of the options or go for “Custom” to create a customized format with codes.

When dealing with **subtracting time in Excel**, remember:

- You may need to use multiple formats for multiple columns.
- You may have issues with times less than 24 hours displaying correctly.

**Tip:** Double-check your inputs to keep a correct datetime data format and avoid errors.

Now that you understand customization, it’s time to set the time format to **hours, minutes, and seconds**!

### Set the Time Format to Hours, Minutes, and Seconds

To format time data to hours, minutes, and seconds in Excel, follow these five steps:

- Select the cells with the time data.
- Right-click them and select “Format Cells.”
- Under “Number,” choose “Custom.”
- In the “Type” box, enter “h:mm:ss”.
- Click “OK” to apply the custom format.

Now let’s look at how this helps. To subtract one time from another, convert each timestamp into a decimal value using `24*60*60`

. Then subtract one decimal from the other to get a new decimal value representing the duration in seconds. Finally, use the `MOD`

function by dividing the result with 86400 (the total number of seconds in a day).

It is crucial to format cells before subtracting times. If they are not formatted properly, it could lead to unexpected results that don’t represent the actual elapsed time.

Experiment with worksheets containing date and hour-minute-second columns, keeping in mind the formatting rules discussed.

It is important to be careful. A study titled ‘**Spreadsheet Errors: Observations from the Lab**‘ found that over 80 percent of spreadsheets contain at least one error.

Now let’s move on to our discussion about **Two Methods to Subtract Time in Excel**.
