About this app

Compare tax-inclusive prices across three tax rates at once.

WHAT IT DOES
- Calculate the tax-inclusive price from a price excluding tax
- Work backwards from a tax-inclusive price to the price before tax
- Set three tax rates and compare the results side by side
- See the difference from your base rate, colour-coded (higher in red, lower in green)

WHEN IT HELPS
- Checking how much a reduced rate changes the final price
- Working out what a "plus tax" price actually comes to
- Calculating with a rate from another country

Tax rates are free-form, so it works for VAT and sales tax as well as
Japanese consumption tax.

DETAILS
- The same screen on iPhone, iPad and Mac
- Japanese, English and Chinese
- No network needed. What you type never leaves your device
