## Step-by-Step Tutorial: How to Do Percent Difference in Excel

In this guide, you’ll learn how to calculate the percent difference between two numbers in Excel, step by step. This will help you quickly see how much one value has increased or decreased compared to another.

### Step 1: Open Your Excel Spreadsheet

Start by opening your Excel file that contains the values you want to compare.

Being familiar with Excel’s interface will save you time. If you don’t have your data ready, you can enter it into two separate cells.

### Step 2: Identify Your Two Values

Find the two cells that contain the values you want to compare.

Let’s say you have one value in cell A1 and another in cell B1. These will be the numbers you use to calculate the percent difference.

### Step 3: Click on an Empty Cell

Select an empty cell where you want the percent difference to appear.

This cell will display your result, so make sure it’s in a spot that’s easy to see and reference later.

### Step 4: Enter the Percent Difference Formula

Type `=(B1-A1)/A1`

into the empty cell and press Enter.

This formula calculates the difference between the two values and then divides that difference by the original value. The result will be a decimal.

### Step 5: Format the Result as a Percentage

After pressing Enter, format the result cell as a percentage.

To do this, click on the cell with the decimal result, then go to the Home tab and click the Percent Style button. Now your result will display as a percentage!

After you complete these steps, your selected cell will show the percent difference between the two values. This makes it easy to see the relative change, whether it’s an increase or decrease.
