Calculating the percent difference in Excel is a straightforward task. You simply need two numbers, a formula, and basic knowledge of Excel functions. By following these steps, anyone can quickly find the percent difference between two values, making it useful for various applications like budgeting, analyzing data, or comparing figures.
Step by Step Tutorial: How to Calculate Percent Difference in Excel
This tutorial will guide you through each step needed to calculate the percent difference between two values using Excel. By the end, you’ll be able to apply this formula to any set of numbers.
Step 1: Open Excel and Input Your Data
First, open Excel and enter the two values you want to compare in separate cells.
Imagine you have the numbers 50 and 70. Place 50 in cell A1 and 70 in cell A2. This sets the stage for your calculation.
Step 2: Select an Empty Cell for the Result
Next, choose an empty cell where you want the result to appear.
Picking a nearby cell, like A3, keeps your worksheet organized and makes it easy to follow along with subsequent steps.
Step 3: Enter the Percent Difference Formula
In the empty cell, type the formula: =ABS((A2-A1)/((A2+A1)/2))*100.
This formula calculates the absolute percent difference between the two numbers in cells A1 and A2. The ABS function ensures the result is always positive.
Step 4: Press Enter to Calculate
Hit Enter to apply the formula and see the result.
The cell will instantly display the percent difference. For our numbers, the result will be approximately 33.33%.
Step 5: Format the Result as a Percentage
Finally, format the result cell as a percentage for easier reading.
Right-click the result cell, choose "Format Cells," select "Percentage," and set the decimal places if desired. This makes the result look cleaner and more professional.
After completing these steps, you’ll have the percent difference displayed in a clearly formatted cell. This simple method can be applied to any two numbers in your Excel worksheet.
