Understanding the Basics of Excel Formulas

The first thing to remember when trying to subtract two columns in Excel is understanding the basics of Excel formulas.

How to Subtract Two Columns in Excel

Step 1: Open a New Workbook

Start by opening Excel and creating a new workbook. In the workbook, create two columns containing the numbers or values you want to subtract. For this guide, we will use Column A and Column B.

Step 2: Enter the Formula

To subtract one column from another, you will need to enter the formula into a new column. For example, if you want to subtract Column B from Column A, you need to create a new column and enter the following formula: =A1-B1

Step 3: Copy the Formula

After entering the formula, you must copy it down to the rest of the rows in that column. To do this, select the cell with the formula and drag the bottom-right corner of the cell down through the rest of the cells where you want the formula to apply.

Step 4: Adjust the Format

By default, the result of the formula will appear in the same format as the original numbers. If you want to change the format of the result, change the number format in the “Home” tab in the ribbon.

Useful Tips for Subtracting Two Columns in Excel

Now that we have covered the basic steps to subtract two columns using Excel, let’s look at some helpful tips that will make the process even more efficient.

Tip 1: Use the Absolute Cell Reference

When you copy the formula down to other cells, the cell references in the formula will change to match the new location. If you want the cell reference to remain fixed, use an absolute cell reference. To do this, add a dollar sign before the column letter and row number. For example, =$A$1-$B$1.

Tip 2: Check for Errors

Excel has an error-checking feature that can help you identify and correct errors in your formulas. If the result of your formula is not what you expect, click on the cell and look for the green triangle in the top left corner of the cell. Click on it for suggestions to review and correct the error.

Tip 3: Use Conditional Formatting

You can use conditional formatting to highlight cells that meet certain criteria. This is a useful tool when working with large datasets. For instance, to highlight cells where the result of a formula is negative, go to “Conditional Formatting” under the “Home” tab, create a new rule, select “Format only cells that contain,” and choose “Less than” with the value of zero.
