FAQ
- 1How do I calculate 20% off?
- Multiply the original price by 0.8. For example, 20% off 3,000 yen is 3,000 × 0.8 = 2,400 yen.
- 2What percent off is 500 yen off?
- Divide the discount amount by the original price and multiply by 100. For example, 500 yen off 2,500 yen is 20% off.
- 3Is 20% off and then 10% off the same as 30% off?
- No. Applying 20% off and then 10% off to 10,000 yen results in 7,200 yen, which is effectively 28% off.
- 4Should I calculate from tax-included or tax-excluded prices?
- Use tax-included prices when you want the amount you will actually pay. For tax-excluded prices, check the discounted price after adding tax.
- 5Why can the result differ from a store by one yen?
- Rounding and tax calculation order differ by store and service, so small one-yen differences can happen.
