Discount Calculator is an online tool that calculates discounted prices and savings from the original price and discount rate. Enter the original price and discount percentage to instantly see the sale price and amount saved. It also supports multiple stacked discounts (e.g., 30% OFF then additional 10% OFF) and accurately calculates the final effective discount rate.
Multiple discounts are applied sequentially. For example, with ¥10,000 at 30% OFF then 10% OFF: First ¥10,000 × 70% = ¥7,000, then ¥7,000 × 90% = ¥6,300. Note: 30% + 10% does NOT equal 40% OFF.
The effective rate is the actual percentage saved from the original price. In the example above, the final price of ¥6,300 is 37% off the original ¥10,000, so the effective rate is 37%.
Because the second discount is applied to the already-discounted price, not the original. Each subsequent discount is applied to a smaller base amount, resulting in a smaller actual discount.
The tool calculates decimal values for accuracy. For actual purchases, stores typically round to the nearest yen, which may result in slight differences from the displayed amounts.
