Frequently asked questions
What's the difference between adding and extracting tax?+
Adding starts from a tax-exclusive price and adds tax on top (common for US receipts). Extracting starts from a tax-inclusive total (common for EU VAT-inclusive prices) and works backwards to find the net price and tax.
How do I extract tax from a VAT-inclusive price?+
Net = Gross ÷ (1 + rate/100). For example, with 20% VAT, a £120 gross price has a £100 net price and £20 of VAT.
Does this handle multiple tax rates?+
It calculates one rate at a time. For combined rates (e.g. state + city sales tax), add the rates together and enter the combined percentage.
