# How to Do a Subtraction Formula in Microsoft Excel

Microsoft Excel makes it easy to perform simple calculations, including subtraction. Whether you’re managing a budget, analyzing sales, or tracking expenses, knowing how to create a subtraction formula is fundamental for accurate data analysis.

## How to Do a Subtraction Formula in Microsoft Excel

In MS Excel, creating a subtraction formula is straightforward, allowing you to perform accurate calculations for various analysis needs. Follow these steps to subtract values and enhance your Excel proficiency:

• ### Step 1. Open Excel and Prepare Your Data

Start by launching Microsoft Excel and opening your worksheet. Identify the cells containing the values you want to subtract. It’s helpful to label these cells or include column headers for clarity.

• ### Step 2. Select the Cell for the Result

Click on the cell where you want the result of the subtraction to appear. This will be the cell where you enter your subtraction formula.

• ### Step 3. Enter the Subtraction Formula

In the selected cell, type “=” to start the formula, followed by the cell reference of the first value you want to subtract. Type “-” and then enter the cell reference of the second value. For example, to subtract the value in cell “B2” from the value in cell “A2,” you would type “=A2-B2.”

• ### Step 4. Complete and Review the Formula

Press “Enter” to complete the formula. Excel will calculate the result and display it in the selected cell. Review the formula to ensure it’s correctly entered and that the result matches your expectations.

• ### Step 5. Copy the Formula (Optional)

If you need to apply the same subtraction formula across multiple cells, click on the cell with the formula and drag the fill handle (the small square at the bottom right corner) down or across other cells. This will copy the formula, adjusting the cell references accordingly.
