It is a calculator app that supports reduced tax rates that can calculate 8% and 10% consumption tax.

The feature of this app is that the calculation frame is set up individually for each tax rate.

For this reason, you can check the 8% and 10% tax-inclusive amounts at the same time without changing screens or erasing the entered values.

And the total value of each tax-inclusive amount is automatically calculated, so you can check the total amount without any hassle.

You can conveniently use it when you need to calculate consumption tax, such as when shopping, selling products, estimating, and writing on slips.

You can enter a formula such as 100+300 or 100×3, so you can calculate the tax-inclusive amount of multiple products at once.

In addition to tax included, tax excluded and tax amount are displayed separately.

(Example tax included: 110 tax excluded: 100 tax: 10)

You can calculate discounts.

5%, 10%, 15%, 20%, etc. can be calculated simply by pressing a preset button, so the operation is easy.

You can also enter a numerical value and calculate it as a percentage.

Calculation results are automatically saved in history and can be checked later.
