How to Calculate Price with a Percentage Off

You can easily calculate the final price of an item and the amount you will save if you know the percentage off. This is a commonly used discount formula for products and services that reduces the price of the product by a percentage off.

Step One: Convert Percent Off to a Decimal

The first step is to convert the percentage to a decimal number. This is necessary, so we can use the percentage in a simple formula.

To convert a percent to a decimal number, simply divide by 100. You can also use our convenient decimal to percent calculator.

For example, let’s convert 15% to a decimal number.

percent as decimal = 15% ÷ 100
percent as decimal = .15

Step Two: Calculate the Savings

The next step is to multiply the decimal percent by the initial price to find the savings amount.

For example, find the savings of a $40 item with a .15 decimal percent off.

savings = $40 × .15
savings = $6

Step Three: Calculate the Final Price

To calculate the final price after the percent off, subtract the savings amount from the initial price.

For example, calculate the final price of a $40 item with 15% off – remember this is a $6 savings.

final price = $40 – $6
final price = $34

You can also use our discount calculator to simplify this calculation.

Many companies will also offer a stackable discount, which means that they offer an additional percentage off of a product where a discount is already being offered. If this is the case, you can use the formula above and iterate through it again to apply the additional percentage off.
