Discount price comp calc 3 12+

This app was designed for use in Japan based on Japanese law.

"Discount price comp calc 3" is an app that can easily compare discount and mileage.
It became easy to understand by specializing only on the comparison of discount and mileage.
3 products are compared and ranked and displayed in order of

200 yen discount with 1000 yen including tax
20 % discount with 1000 yen including tax
200 yen including tax discount with 1100 yen including tax.

We compare these 3 products and rank them in order of low price.

Mileage can be calculated considering the overall multiplication factor. If you select the mileage calculation, it will not be the amount actually paid but it will be judged by the converted price.

50% discount with 1000 yen including tax.
50% mileage are given at 1000 yen including tax.

For example, compare the case where 50% discount and 50% mileage are given at 1000 yen including tax. First one is 167yen saved. 1st one is a discount of 50% at 1000 yen is 500 yen. 2nd one is 667 yen. This is given 500 miles for 1000 yen, so we thought that it cost 1,000 yen to buy a thing of 1500 yen It is 1000 ÷ (1000 + 500) as the overall multiplication rate 2/3, 66.7%. If you multiply it by the amount of 1000 yen actually paid, it will be the converted price considering the whole multiplication rate. So, that's why 667 yen.

When purchasing next by the miles you received, mileage is not given often. In this case, this calculation method is recommended.

If you consider mileage discount as it is, it is an answer that you wanted by calculating it as discount and discount rate without thinking hard.

Simplify troublesome discount price comparisons with this app and shop for great deals.
If discounts and mileage grants overlap, you may not really understand at all. I think that there are not many scenes to use so much, but please be always on your smartphone for that time.
