How to Use the Percentage Change Formula in Google Sheets 📝
Google Sheets is a versatile tool that simplifies calculations, including percentage changes. Below, we will walk through step-by-step instructions to effectively use the percentage change formula.
Step-by-Step Guide
-
Open Google Sheets: Start by opening a new or existing Google Sheets document.
-
Input Your Data:
- In Column A, enter your old values.
- In Column B, enter your new values.
Old Value (A) New Value (B) 100 120 150 180 200 220 -
Select the Cell for the Formula: Click on the cell in Column C (for example, C2) where you want the percentage change to appear.
-
Enter the Percentage Change Formula:
- Type in the formula as follows:
=((B2-A2)/A2)*100 - This formula subtracts the old value (A2) from the new value (B2), divides it by the old value (A2), and multiplies by 100 to express it as a percentage.
- Type in the formula as follows:
-
Drag to Fill Down: After entering the formula in C2, you can drag the small square at the bottom-right corner of the cell down to fill the formula for additional rows.
-
Format Your Cells: If you want to display the results as percentages, select the cells in Column C, click on Format > Number > Percent from the menu.
Understanding the Result
When you apply the formula, the results will indicate the percentage change from the old values to the new values. For example, in the table above:
- For the first row, from 100 to 120, the percentage change is 20%.
- For the second row, from 150 to 180, the percentage change is 20%.
- For the third row, from 200 to 220, the percentage change is 10%.
