Method and assumptions
Order: increase, successive discounts, remove included VAT, add net shipping, VAT and withholding.
Shipping charged at cost, with the same VAT and withholding as goods. No country-specific tax rules.
Profit excludes VAT and withholding. Unit cost excludes VAT; withholding applies to the base including shipping.
Worked example and interpretation
For a net price of 100 at an example rate of 21%, tax is 21 and the total is 121. To extract that tax from 121, divide by 1.21 to recover 100. Subtracting 21% from 121 would incorrectly give 95.59.
What to check
21% is an example, not a determination of the legal rate. Check country, product and the tax base for shipping or withholding. Changing the currency symbol does not convert amounts or tax rules.
