Description
Free, easy, simple, and quick to use!
"20% OFF" "30% off"... If you're not good at calculating discounts, leave it to Zeitaku!
How much is the consumption tax? ... It's fine when you're stuck in a store that displays prices excluding tax or when you want to know the base price.
This is a convenient and easy consumption tax and discount calculator that supports the consumption tax rate of 10% and the reduced tax rate of 8%.
If you have iOS 17.0 or higher, you can add a "widget" to your home screen and quickly calculate discounts without launching the app.
--How to use--
Just enter the amount.
Scroll through the discount rates to select the discount rate.
For more information, please see the tutorial in the app.
*Supports tax-exclusive and tax-inclusive (tax-exclusive and tax-inclusive)
You can select tax-exclusive or tax-inclusive from the "tax-inclusive/tax-exclusive button" or the settings button on the center left of the screen.
If you select tax-exclusive, enter the price excluding tax to display the price including tax.
If you select tax-inclusive, enter the price including tax to display the base price.
*Tax rate
The consumption tax rate can be switched between 8% and 10%.
*Discount calculation/% calculation
You can calculate the percentage off or discount.
When entering tax-excluded amounts, the discount tax-excluded amount, consumption tax, discount tax included, and the difference are displayed.
When entering tax-included amounts, the discount tax included and the difference are displayed.
*Entering decimal points
You can enter decimal points by pressing and holding the "0" key.
*Fixing the discount rate
If you turn on the fixed discount rate in the settings screen, you can calculate more efficiently when calculating multiple times with the same discount rate. If you turn it off, the discount rate will be cleared to 0 when you press the [C] key.
*Setting the fractional calculation method
You can set the fractional calculation method for consumption tax calculation and discount calculation as an option.
You can choose to round down, round up, or round to the specified decimal point.
When entering tax-excluded amounts for discount calculation, the discount tax-excluded amount will be rounded.
When entering tax-included amounts for discount calculation, the discount tax included amount will be rounded.
*About the paid version and other related apps
This app is also available in a paid version. You can use shopping memos, calculation result saving functions, and more without ads.
◆NEW!! The "Tax Table R for Reduced Tax Rates" app has arrived
This is a convenient app for when you want to calculate the total amount of your shopping or for each tax rate, and it also has a shopping memo function, so please give it a try.
*Fractional treatment of consumption tax varies depending on the store, and may differ from what is displayed in this app.
*This app does not guarantee accurate amount display. Also, please note that we cannot take any responsibility for any trouble that occurs in relation to the use of this app.
