FAQ
What’s the difference between net and gross?
Net is the price before VAT. Gross is the price after VAT is added.
How do you remove VAT from a gross price?
Net = Gross ÷ (1 + rate). VAT = Gross − Net.
Can I use a custom VAT rate?
Yes — choose “Custom…” and enter a percentage. (Handy for historical rates or non-UK calculations.)
