How to Calculate Price with a Percentage Off
You can easily calculate the final price of an item and the amount of savings if you know the 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 sale price discount calculator to simplify this calculation.
