# How to Do a Percentage Increase in Microsoft Excel

Microsoft Excel is an invaluable tool for calculating percentage increases, allowing you to track growth and changes across various data points effectively. Whether you’re managing budgets, measuring sales growth, or analyzing performance metrics, understanding how to compute percentage increases is essential for accurate calculations.

## How to Do a Percentage Increase in Microsoft Excel

In Microsoft Excel, understanding how to calculate a percentage increase is crucial for analyzing data over time, allowing you to measure growth and evaluate changes effectively. This guide will take you through the steps to perform this calculation accurately.

• ### Step 1. Input Your Data

Start by entering your original value and the new value into two separate cells in Excel. For instance, place the original value in cell A1 and the new value in cell B1.

• ### Step 2. Subtract to Find the Difference

In a new cell, calculate the difference between the new value and the original value by using the formula “=B1-A1.” This formula subtracts the original value in cell A1 from the new value in cell B1, giving you the change in value.

• ### Step 3. Divide the Difference by the Original Value

Next, to find the increase as a fraction of the original value, use the formula “=(B1-A1)/A1” in another cell. This calculation provides the decimal form of the percentage increase.

• ### Step 4. Convert to Percentage

To convert the result from step 3 into a percentage, multiply it by 100. You can do this within the same cell by extending the formula: “=((B1-A1)/A1)*100.”

• ### Step 5. Format as Percentage

Finally, to display your result as a percentage, select the cell with your result, go to the “Home” tab, and in the “Number” group, click on the “Percentage” style button. This will format the number as a percentage, making it easier to read and understand.
