What this tool does
The most common calculation for quotes and invoices, tax-inclusive or exclusive: enter an amount to get the pre-tax amount, tax and total, with tax rounded to the dollar like on Taiwanese invoices.
Plan promotions first: the price after 20% or 15% off; what discount selling at NT$990 is; the average price per item and the effective discount for “second item 40% off”, buy two get one free or three for NT$1,000; and how much more is needed for “NT$100 off every NT$1,000”.
Profit: enter your cost, price, platform fee and shipping to see profit per item, gross margin and markup, and whether you still make money after discounts; you can also work out a suggested price from a target margin.

FAQ
How do I convert a tax-inclusive price to pre-tax?
Pre-tax = tax-inclusive ÷ 1.05, rounded to the dollar; tax = tax-inclusive − pre-tax. For example, NT$1,000 including tax: NT$952 before tax and NT$48 tax.
What does an “85 zhe” discount mean?
In Taiwan a discount is written as the share you still pay: “85 zhe” means paying 85% of the original price, i.e. 15% off; “8 zhe” is 80%, i.e. 20% off. Enter “8” or “85” and both work.
What's the difference between gross margin and markup?
Gross margin = profit ÷ price; markup = profit ÷ cost. Cost 300, price 500: profit 200, markup 67%, gross margin 40%. They're easy to mix up when pricing, and getting it wrong makes you think you earn more than you do.
What does “second item 60%” work out to?
Averaged over two items it's 20% off (one at full price + one at 60% = paying for 1.6 items to get 2). The tool shows the average price per item directly.
