About

“Japan Consumption Tax Calc” calculates Japanese consumption tax and other amounts from Base Price or Tax-Included Price. (How to Use) • Enter a value using the keyboard and tap the "=" key to calculate. • "10% Tax" means" 10% Consumption Tax. • The entered value can be used as either the Base price or the Tax-included price. The value will be applied to the field with the bold border. You can change fields by tapping them to move the bold border. • Tap and hold the "Select Tax Rate” key to switch between different tax rate combinations. There are three available combinations: 8% & 10%, 1% & 10%, and 1% & 8%. • "< Prev" key recalls the previously used input value. Continuing to tap will recall an even older input value. If you recall an input value that is too old, you can use "Next >" key to return to a newer input value. (About Calculations) • For consumption tax calculations on this calculator, any fractions of a yen less than 1 yen are rounded down. • If the entered value is a tax-included price and its tax amount requires rounding up, both the rounded-up tax amount and the tax-included price will be displayed in blue text. (For example, when a 10% tax-included price is 1,000 yen.) • Any fractions less than 1 yen in the calculated input values are rounded down before use. The developer assumes no responsibility for any loss or claims by third parties which may arise from the use of this app.
