Frequently Asked Questions
What is the difference between exclusive and inclusive tax? expand_more
Exclusive tax (US sales tax) is added on top of the sticker price. Inclusive tax (EU VAT, GST) is already embedded in the displayed price and must be extracted to find the net amount.
How is inclusive tax extracted? expand_more
Net = Gross / (1 + rate/100). The tax is Gross - Net. For example, 100 USD gross at 20% VAT means 83.33 net and 16.67 tax.
Does this handle income tax? expand_more
