We use two simple formulas depending on whether the input price is tax-inclusive or exclusive:
tax = amount × (rate / 100)total = amount + taxsubtotal = amount / (1 + rate / 100)tax = amount − subtotal| Symbol | Meaning |
|---|---|
amount | User-entered value (either gross or net) |
rate | Tax rate in percent (e.g. 20 for 20%) |
subtotal | Net amount before tax |
tax | Tax portion of the total |
total | Gross amount including tax |

Tax-exclusive pricing means the amount you enter does not include tax — tax is calculated on top (US style). Tax-inclusive pricing means the amount already includes tax — we back-calculate the tax portion (EU VAT style). Toggle between the two with the 'Price Type' selector.
These are representative averages: 8.5% is a typical combined US state+local sales tax, 20% is the standard EU VAT rate, and 17% is the common Brazil ICMS rate for most goods. Actual rates vary by state, country, product category, and whether you're a registered business.
