While the resulting value is correct, it’s not in the right format that you want in the cell.Īnd this has a really easy fix – you just need to change the cell format. Sometimes you’ll notice that after you have subtracted a percentage value from a number, the resulting value isn’t in the proper format (sometimes it shows a percentage value instead of a number).

As you can imagine, this formula can get quite long. To do this, I have added a new column named Running Subtraction Total, where I will show the running subtraction total. The formula below subtracts the value in cell A2 and the value in cell A3 from the value in cell A1. Using Basic Subtraction Formula in Excel In this method, we are going to use the basic subtraction formula, also known as the minus formula, to create a running subtraction total in Excel. Don't forget, always start a formula with an equal sign (). Converting Percentage Back to General Values Simply use the minus sign (-) as the subtraction operator. In case you do not want this to happen, you can convert the formula into values (i.e., remove the formula and only keep the values). Note that the result of this formula is dynamic, which means that in case you change the Sales value or the Commission percentage value, it would automatically update. In the above formula, instead of calculating the percentage value that we need to multiply with the number, we use the value of the initial sale (in cell B2) and subtract the commission sales value (given by B2*C2) from it. You can also use the below formula: =B2-B2*C2 Since 100% is equal to 1, to deduct a specific percentage value from a number, we first calculate the deducted percentage value by subtracting the percentage value from 1, and then multiplying it with the number.
