How to Add Percentage to Price with Excel Formula (2 Ways)

In this tutorial, I will show you how to add a percentage to a product’s price using an excel formula. Luckily, adding percentages to a price is very easy. Let’s assume a product’s price has increased by 20%. It means in every $100, the price has increased by $20. Often, we have to calculate the price increase for a product when its piece is raised by a certain percent. Similarly, while offering a discount on a product, we have to calculate the decreased price. So, let’s go through the tutorial.

Importance of Cell’s Number Formatting During Percentage Calculation

Before entering a percentage in excel cells, remember you have to change the cell’s Number format. For example, if you write 12 in a cell and then apply the ‘%Number format, excel will display the number as 1200%. Eventually, this will return an error in calculation. So, to get the desired cell Number format you may follow the below instructions.

Steps:

  • Type a decimal number (.12)  in Cell D5.

2 Ways to Add Percentage to Price with Excel Formula

1. Add Percentage to Price Applying Simple Formula

Let’s assume, we have a list of grocery items with their old price and price increment percentage. Now, I will add these below percentages to the old prices and hence calculate the new prices.

Add Percentage to Price Applying Simple Formula

I have used several formulas to add the percentages. Let’s explore them one by one.

📌 Formula 1:

For instance, the old price of the Whole Grain Pasta was $10. Now the price has increased by 12%. So, I will add 1 to 12%, which results in 112%. Then I will multiply the older price $10 with 112% and get the new price ($11.20).

Steps:

  • Type the below formula in Cell E5 and press Enter.
=C5*(1+D5)

  • Then you will get the new price for Whole Grain Pasta. Now, use the Fill Handle (+) tool to get the new price of the rest of the items.

📌 Formula 2:

Instead of using the previous formula (Formula 1), we can use the below formula to add percentages to the old price:

=C5+C5*D5

📌 Formula 3:

Now I will use Formula 1 in two steps. First, I will add 1 to the increased percentage. To do that see the following steps.

Steps:

  • Type the below formula in Cell E5, hit Enter, and use the Fill Handle tool to get the formula copied in range E6:E12.
=1+D5

  • Finally, apply the Fill Handle tool to copy the formula to the rest of the cells and here we get the new prices.

📌 Formula 4:

Here, I will multiply old prices with increased percentages to get the increased amount in USD. Later, I will apply the SUM function to add each old price and increased amount.

Steps:

  • First, type the below formula in Cell E5, hit Enter on the keyboard. Next, use the Fill Handle tool to copy the formula to the rest of the cells.
=C5*D5

  • Then, type the below formula in Cell F5.
=SUM(C5+E5)

  • In the beginning, type the below formula in Cell E5, press Enter, and copy the formula over the range E5:E12.
=1+D5

Deduct Percentage from Price

In case you are offering a discount on some products, you have to subtract a certain percentage from the original price. To do that simply subtract the percentage from 1 and then multiply the result with the original price. To illustrate, I have applied discounts on the grocery items of the previous example.

Steps:

  • Type the below formula in Cell E5 at first.
=C5*(1-D5)

Deduct Percentage from Price

  • Then hit Enter, copy the formula to the rest of the cells using the Fill Handle tool and get the new decreased prices.

Things to Remember

➤ Make sure you have added parenthesis on some of the above formulas such as =C5*(1-D5). This is because excel performs multiplication operations before subtraction or addition. In that case, some of the above formulas will return the wrong result. So to get the exact result, pass the second part of the formula in parenthesis.

➤ You can bring the Paste Special dialog box using the keyboard shortcuts (Ctrl + Alt + V).
