VAT Calculator
Add VAT to a net amount, remove it from a gross amount, or switch to the Flat Rate Scheme estimator to see roughly what you'd owe as a percentage of your turnover.
The add/remove calculator is a quick, exact bit of arithmetic for invoicing or pricing. The Flat Rate Scheme side is a rougher estimate — it compares the VAT you'd charge on sales under the standard scheme against a fixed percentage of turnover, but doesn't know how much VAT you'd otherwise reclaim on purchases, which is the main thing that actually decides whether the flat rate scheme suits your business.
These figures are unofficial, indicative estimates only — not a tax return, an HMRC calculation, or financial, tax or legal advice. Always confirm your position with a qualified accountant or tax adviser before acting on it.
