Calculate value added tax in both directions. Choose add mode to apply a VAT rate to a net price and see the VAT amount plus the gross total, or choose remove mode to strip VAT out of a gross price and recover the net figure and the tax it contained. This is exactly what you need when invoicing, checking a receipt, or reconciling expenses where prices may be quoted with or without VAT. You can enter any rate, so it works for the different standard and reduced rates used across countries. Because it only handles numbers, it is currency-agnostic. Switch modes and the result recalculates instantly, with everything computed locally in your browser and nothing sent anywhere.
