Discount Calculator
Enter the original price and a discount percentage, and instantly see what you actually pay and how much you save. A second, optional discount handles the “extra 10% off sale prices” case that always trips shoppers up.
Stacked discounts are applied one after another, and the tool shows the effective combined rate — because 20% + 10% off is 28% off, not 30%, a difference that adds up on big-ticket items.
Frequently asked questions
Why isn't 20% + 10% the same as 30% off?
The second discount applies to the already-reduced price, not the original one: 100 → 80 (−20%) → 72 (−10%), which is 28% off in total. The calculator shows this effective rate so you can compare deals fairly.
How do I find the original price from a sale price?
Divide the sale price by (1 − discount ÷ 100). A $72 price after 28% off comes from 72 ÷ 0.72 = $100. Or use the Percentage Calculator's “X is what % of Y” mode to work it out step by step.
Does this account for VAT or sales tax?
No — it works on the prices you type. If the ticket shows a tax-inclusive price, the discount result is also tax-inclusive. To combine with tax, run the discounted price through the VAT or GST calculator.
