Adding percentages using Excel might seem challenging at first, but once you get the hang of it, it’s a breeze. You simply need to use the right formulas and make sure your cells are formatted correctly to display percentages. By the end of this article, you’ll be able to confidently calculate and add percentages in Excel like a pro.
Step by Step Tutorial on Adding Percentages Using Excel
Before diving into the steps, let’s understand what we’re aiming to achieve. We’re going to learn how to calculate the percentage of a number and then how to add that percentage to another number in Excel. This could be useful in various scenarios, such as calculating tax, discounts, or interest rates.
Step 1: Format your cells to display percentages
Select the cells you’ll be working with and format them as percentages.
This step is essential because if your cells aren’t formatted to display percentages, Excel will treat your numbers as whole numbers instead. To format the cells, right-click on your selected cells, choose ‘Format Cells,’ then select ‘Percentage’ and set the decimal places you desire.
Step 2: Enter the percentage formula
Type in the formula to calculate the percentage of a number. The formula is =A1*B1, where A1 is the cell with the number, and B1 is the cell with the percentage you want to calculate.
Remember that Excel uses a decimal system for percentages, so if you want to calculate 20%, you should type 0.20 in the cell. The formula will multiply the number by the percentage and give you the result as a percentage of the original number.
Step 3: Add the percentage to another number
Use another formula to add the calculated percentage to another number. The formula is =A1+C1, where A1 is the original number, and C1 is the cell with the calculated percentage.
Once you have your percentage calculated, you can simply add it to another number by using the addition formula. Make sure to use the cell references accurately to get the correct result.
Step 4: Verify your results
Double-check your results to ensure the accuracy of your calculations.
It’s always a good idea to go over your calculations. A small mistake in Excel can lead to incorrect figures, especially when working with formulas. Verify your results by manually calculating the percentages and comparing them with what Excel has given you.
After completing the above steps, you will have successfully calculated and added percentages using Excel. This can be useful in many financial or data analysis tasks, and mastering it can save you a lot of time.

- Check your work by doing the math separately to ensure the formulas are working correctly.
