Discount Calculator: tips and things to know
- In Japanese shops discounts are often written in "wari" (割): 3割引 means 30% off, 半額 means half price.
- Sale tags may show the discount on the tax-excluded price, so the till total is the discounted price plus 10% (or 8% for food).
- Preset buttons cover the common rates; type any other value directly.

Reading discount signs in Japan
Japanese sale signs use two systems. "○%OFF" is the familiar percentage. "○割引" (wari-biki) counts in tenths: 1割 is 10%, 3割引 is 30% off, 5割引 is half price. You will also see 半額 (hangaku, half price) and 2割増 (a 20% increase).
Supermarkets mark down fresh food in the evening with yellow stickers such as 30%引 or 半額; the discount applies to the tax-excluded price and tax is added at the till.
Tax on discounted prices
Consumption tax is charged on the price after the discount. Choose 10% for most goods or 8% for food and non-alcoholic drinks to see the amount you will actually pay. Choose "no tax" if the shelf price already includes tax.
Discount Calculator FAQ
Is "3割引" the same as 30% off?
Yes. One wari is one tenth, so 3割引 takes 3/10 (30%) off the price. You can enter the discount either way.
How is rounding handled?
The discount and the tax are both rounded down to the yen. A shop may round differently, so a difference of a few yen from the till is normal.
Which items get the 8% rate?
Food and drinks other than alcohol, and subscription newspapers. Eating in at a restaurant or café is 10%.
