How to Find Percent Change in Excel: A Step-by-Step Guide for Beginners

Finding Percent Change in Excel

Calculating percent change in Excel is a handy skill that can help you understand how values have increased or decreased over time. This can be especially useful for comparing sales figures, tracking expenses, or analyzing data trends. In just a few simple steps, you can quickly find the percent change between two numbers in Excel.

Step by Step Tutorial: How to Find Percent Change in Excel

In this tutorial, we’re going to walk you through the process of calculating percent change in Excel. By the end, you’ll be able to quickly and accurately determine the percent change between any two numbers in your dataset.

Step 1: Open your Excel Spreadsheet

First, open your Excel spreadsheet where you have the data you want to analyze.

Make sure your data is organized in a clear manner, with the numbers you want to compare easily accessible. For example, you might have last month’s sales figures in one column and this month’s sales figures in another.

Step 2: Select the Cell for the Percent Change Result

In an empty cell, select where you want the percent change result to appear.

Choosing the right cell helps keep your spreadsheet organized. This cell should be adjacent to the numbers you are comparing to make it easy to understand the result.

Step 3: Enter the Percent Change Formula

Type the following formula: =(New Value - Old Value) / Old Value * 100.

This formula calculates the difference between the new and old values, divides by the old value to find the rate of change, and multiplies by 100 to convert it to a percentage.

Step 4: Replace Formula Placeholders

Replace "New Value" and "Old Value" with the actual cell references. For example, if your old value is in cell B2 and your new value is in cell B3, the formula would be =(B3 - B2) / B2 * 100.

Using cell references ensures your formula updates dynamically if the data in those cells change. This is key for maintaining accurate results.

Step 5: Press Enter to See the Result

Hit Enter on your keyboard to display the percent change in the selected cell.

If entered correctly, you will see the percent change between your old and new values. Positive results indicate an increase, while negative results show a decrease.

After completing these steps, your Excel sheet will display the percent change between the two values you compared. This can give you quick insights into your data trends.

Tips for Finding Percent Change in Excel

• Use Absolute References: If you plan to drag the formula to other cells, use absolute references (e.g., $B$2) to keep the cell reference constant.
• Check for Zero Values: Avoid dividing by zero by ensuring your old value is not zero. This will prevent errors in your calculations.
• Apply Number Formatting: Format your result cell as a percentage for better readability.
• Double-Check Your Data: Ensure your data is accurate and up-to-date before calculating percent changes.
• Use Conditional Formatting: Highlight significant changes using conditional formatting to make changes stand out visually.
