In detail: VAT Calculator for £20 (Add VAT)
Adding 20% VAT to £20.00 is the everyday calculation for quoting gross prices to UK customers. The net (£20.00) is what you keep; the VAT (£4.00) is collected on behalf of HMRC and paid over in your quarterly return. If you're not VAT-registered, you don't add VAT to your invoices at all — registration is mandatory only above the £90,000 rolling-12-month threshold.
Common misconception: 20% off gross is not the same as the VAT portion of gross. Dividing by 1.2 (or multiplying by 1/6 for the VAT fraction) is the correct method. For £20.00 gross, the true VAT is £3.33 — noticeably different from 20% of £20.00 = £4.00.
At this amount, the VAT difference is small enough to round in your head, but it adds up across a VAT return.
