Good value calculator 12+

Judge the merit of merchandise with different weight, quantity and mileage.

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

When you shopping,
Is there anything confusing which is good value different weight or different capacity?
Do not have any concerns as to how much difference there is with the same capacity?
Have you ever wondered how much you earn for mileage?

Good value calculator resolves the confusion as below.

550ml 368yen, 430ml 265yen
450mlx3 594yen, 430ml 265yen
tax-excluded price 98, tax-included price 104
100yen with discount amount 20yen, 100yen with discount rate 20%
100yen with discount rate 50%, with mileage 50%

If you convert it to the same capacity and quantity as the profitable one, it will show you how much you will saved.

Mileage can be calculated considering the overall multiplication factor.

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 666.7 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, 66.67% Actually pay product price multiplied by 1000 yen will be the 'Converted price including tax' in consideration of the overall multiplication rate. So, that's why 666.7 yen.

When purchasing next by the miles you received, mileage is not given often. In that case we recomend.

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.

If you think that it is a discount for a mileage as it is, it will be the answer you wanted by calculating as a discount amount or discount rate.

I hope this app will help save your living expenses.
