Discount Calculator
Calculate sale prices, discounts, and savings instantly. Find out how much you save with percentage or fixed amount discounts.
Discount factors multiply: 20% followed by 10% saves 28%, not 30%. Tax is an optional user scenario applied after the discount.
Enter complete nonnegative decimals, without grouping (18 digits, 8 decimals). Money inputs: at most 2 decimal places. Every monetary stage is posted to 2 decimals for all currency labels, including JPY; this is a scenario convention, not legal currency precision. All amounts use the selected currency label; no exchange or tax rule is applied.
