About the Discount Calculator
The Discount Calculator works out the sale price and the amount you save from an original price and a discount percentage. It handles a single discount, two stacked discounts, and the reverse case where you know the sale price and want to find the original.
Three modes
- Single discount: the everyday case. Enter the original price and the percent off to see your saving and the final price.
- Double discount: for offers like "30% off, then an extra 10%." The second discount applies to the already-reduced price, not the original, which is why stacked discounts save less than simply adding the percentages.
- Find original: enter a sale price and the discount that was applied to recover the original price and confirm how much was taken off.
How discounts work
A single discount is the original price multiplied by the discount percent divided by one hundred, subtracted from the original. Stacked discounts must be applied in sequence: a 30% discount followed by 10% gives a combined 37% off, not 40%, because the second cut is taken from the smaller amount. The reverse calculation divides the sale price by one minus the discount as a decimal.
Why it is useful
Shoppers use it to check whether a deal is as good as it looks and to compare offers. Retailers use it to set sale prices and verify stacked promotions. The reverse mode is handy when a receipt shows only the final price and you want to know the list price.
Tips
Remember that two discounts never simply add together. If tax applies, calculate the discount first and then add GST with the GST Calculator. To express a price change as a percentage, the Percentage Calculator covers increase and decrease directly. All calculations happen instantly in your browser.
