What Is an Original Price Calculator?
An original price calculator works backwards from a discounted sale price to determine how much an item originally cost before the discount was applied. It uses the sale price and discount percentage to reverse the calculation.
This is useful when checking retail discounts, comparing sale offers, reviewing receipts, calculating previous prices or determining the pre-discount value of a product. Instead of manually rearranging the discount formula, enter the figures into the calculator to get the original price instantly.

How to Calculate the Original Price
To calculate an original price from a discounted price, first determine what percentage of the original price remains after the discount. For example, a 20% discount means that the sale price represents 80% of the original price. Divide the sale price by 0.80 to find the original price.
For example, if an item costs £80 after a 20% discount, divide £80 by 0.80. The result is £100, meaning the item originally cost £100. The discount amount was therefore £20.
Original Price Formula
The formula for finding the original price is Original Price = Sale Price ÷ (1 − Discount Percentage ÷ 100). The discount percentage must be converted to a decimal before it is used in the calculation.
Calculating the Discount Amount
Once the original price has been calculated, subtract the sale price from the original price to find the discount amount. For example, an original price of £100 and a sale price of £80 produces a £20 discount.
Understanding Original Price Calculator Results
The calculator assumes that the sale price is the result of applying a single percentage discount to the original price. For example, a 25% discount means that the sale price represents 75% of the original price.
The calculation does not account for taxes, shipping, fees, additional discounts or other price adjustments. If multiple discounts were applied separately, the original price may need to be calculated using the actual sequence of reductions. Results are mathematical calculations intended for general pricing and shopping purposes.
