Excel makes this calculation simple. However, knowing the right formulas and steps can save you time and effort. In this article, we'll guide you through the process of calculating percentage difference in just a few clicks.

## The Importance of Calculating Percentage Change

Percentage change represents the difference between an original value and a new value, expressed as a percentage of the original value. It is vital for Excel users because it helps analyze data trends, track performance, and make informed decisions.

Whether you're monitoring sales growth, financial performance, or personal goals, calculating percent change in Excel provides clear insights into increases or decreases over time. This makes it easier to communicate findings and identify patterns. Excel's formulas and tools simplify this process, allowing users to efficiently convert raw data into meaningful information.

## Percent Change Formula Excel

The formula for calculating percentage change in Excel is:

$Percentage Change=(Original ValueNew Value−Original Valueโ×100$

To use this formula in Excel, you would type it as:

$$=((\text{NewValue}-\text{OriginalValue})\mathrm{/}\text{OriginalValue)}\ast 100$$

For example, if the original value is in cell A1 and the new value is in cell B1, you would enter:

$$=((B1-A1)\mathrm{/}A\mathrm{1)}\ast 100$$

This formula will calculate the percentage change between the original and new values, giving you a quick way to measure growth or decline. Note that this is the same formula for calculating percentage increase and percentage decrease in Excel.

Here's a step-by-step guide to calculating percentage change in Excel using an example:

### Example:

You have sales data for two months: January and February. The sales for January are in cell **A2** (let's say 100), and the sales for February are in cell **B2** (let's say 150). You want to calculate the percentage change in sales from January to February.

**1. Open your Excel sheet**: Start by opening Excel and entering your data. In this example:

- Enter
**100**in cell**A2**(representing January sales). - Enter
**150**in cell**B2**(representing February sales).

**2. Select the cell for the calculation**: Click on the cell where you want the percentage change to appear (e.g., **C2**).

**3. Enter the percentage change formula**: In cell **C2**, type the following formula: **=((C2-B2)/B2)*100**

This formula subtracts the January sales (A2) from the February sales (B2), divides by the January sales (A2), and multiplies by 100 to get the percentage change.

**4. Press enter**: Hit the **Enter** key, and Excel will calculate the percentage change.
