Find the real price in a sale — the final price after discount and your savings. You can also reverse it: enter two prices to check the true discount percentage.
Mode 1: Price + Discount %

—

Mode 2 (Reverse): Original + Final Price → Discount %

How to use
- In Mode 1 enter the original price and discount % — the final price and savings will show right away.
- If sales tax applies after the discount, also enter the optional tax %.
- In Mode 2 (reverse) enter the original and final price to get the discount % — great for checking a shop sale.
- Both modes calculate live, no button needed.
Tips
- Mode 2 (reverse) is handy for checking whether a shop’s ‘sale’ price is really discounted.
- Enter the tax % only if tax is charged after the discount.
- Shops may round the final amount — small differences are normal.
