How to use the VAT calculator.
Calculate and review
Use the main action when needed. From a net amount, gross = net × (1 + rate). From a gross amount, net = gross ÷ (1 + rate). VAT is the difference.
Try a worked example
If £120 includes 20% VAT, the net amount is £100 and the VAT portion is £20.
Check the assumptions
Rates and tax treatment depend on the product, place and date. The editable rate is more important than the default.
