Final price
Enter a non-negative original price and one discount percentage to subtract price × rate / 100 and show the amount saved and final price. In reverse mode, enter the discounted final price and the tool divides it by 1 − rate / 100 to estimate the original and discount amount. It accepts plain numbers without a currency and does not stack discounts, apply tax or enforce a rate range; a 100% reverse rate can therefore produce a non-finite result. Use sensible inputs and verify checkout rounding. Calculation stays local.
