About this tool

Sales live on confusion: '30% + extra 20%' is NOT 50% off. This calculator gives the final price, the total saving, and the real combined percentage of stacked discounts — so you never fall for fake markdowns.

FAQ

Does 20% + 10% equal 30% off?

No — stacking multiplies: 20% then 10% = 28% total. The tool shows the real number.

Tax before or after discount?

Most countries tax the discounted price — the calculator follows that standard.

Can I compute the original price from a sale price?

Reverse it: sale ÷ (1 − discount%) — divide on this page's input, or ask and we'll add a reverse mode.

Is 50% off + 50% off = free?

Never — it's 75% off. See it live on this page.

Works with any currency?

Yes — math is currency-agnostic; ignore the $ symbol or treat it as your symbol.

Black-Friday honest check?

Compare the shown final price with the item's 30-day history — tools like CamelCamelCamel help; this calculator gives the math part instantly.
