How This Discount Calculator Works
This discount calculator applies one percentage or fixed-amount discount to the original price. It can then apply one optional tax rate to the discounted price.
Formula and Calculation
The core formula used by this discount calculator is: Percentage discount = Original price x Discount rate. Price after discount = Original price - discount amount. Optional tax is then applied to that discounted price.
Enter either one percentage discount or one fixed discount amount. The calculator does not stack or chain multiple discounts; compare complex offers by calculating each sequence separately.
To compare two stores, run each offer separately using the same original price and applicable tax assumptions, then compare the displayed final prices.
