What This Calculator Does
This calculator helps businesses and consumers calculate Value Added Tax (VAT) or Goods and Services Tax (GST). It can add tax to a net price or extract the tax amount from a gross (tax-inclusive) price.
The Formula
To add tax, multiply the net price by the tax rate percentage. To extract tax from a gross price, divide the gross price by (1 + rate) to find the net price, then subtract to find the tax amount.
