Adding vs removing tax
GST and VAT are consumption taxes added as a percentage of a product's price. Adding tax treats your figure as the net (pre-tax) price and adds the rate on top. Removing tax treats your figure as the gross (tax-inclusive) price and works backwards to the net — note this is not the same as simply subtracting the percentage. For example, removing 20% from 120 gives 100, not 96. Calculations run entirely in your browser.
