How the discount calculator works
The discount amount is the original price multiplied by the discount percentage. The sale price is the original price minus that discount.
Example
A 25% discount on $100 saves $25, leaving a sale price of $75.
Tips for comparing deals
A bigger percentage is not always the better deal. Compare the final sale price, not just the discount, and check whether shipping or tax is added at checkout.
Frequently asked questions
How do I calculate a discount?
Multiply the original price by the discount percentage and divide by 100. Subtract that amount from the original price to get the sale price.
How do I find the original price before a discount?
Divide the sale price by (1 − discount ÷ 100). For example, a $75 sale price after a 25% discount means the original price was 75 ÷ 0.75 = $100.
Does this calculator work with any currency?
Yes. The calculation is the same for any currency, so enter the numbers without a currency symbol.
