Calculating Sale Price after Discount
Let’s say, we have a list containing prices and percentage discounts. We can calculate the Sale Price after the discount with this simple formula:
=B3*(1-C3)
The formula can easily be understood by breaking it down into the following 3 simple steps:
Step 1
First of all, we need to prepare the data. Here, in the above table, we’ve created two columns: the original price and the percentage discount.
Step 2
After preparing the data, we’ll take the percentage discount and subtract it from 1.
=1-C3
Step 3

=B3*D3
