VAT Calculator - Add or Remove VAT From Any Price Instantly
Value Added Tax is one of the most widely used consumption taxes in the world, applied in more than 170 countries. VAT = Net Price x VAT Rate. Gross = Net + VAT. Reverse: Net Price = Gross Price / (1 + VAT Rate).
The Formula Explained
Adding VAT (forward): Sophie invoices a client for £3,200 (net). UK VAT at 20%: £3,200 x 0.20 = £640. Total invoice: £3,840.
Removing VAT (reverse): Thomas receives an invoice for €2,856 including 19% German VAT. Net: €2,856 / 1.19 = €2,400. VAT: €456.
Critical error to avoid: Do NOT multiply the gross by the rate. £540 gross at 20% VAT is NOT £540 x 0.20 = £108. Correct: £540 / 1.20 = £450 net. VAT = £90. The VAT fraction for 20%: 1/6 of the gross price.

| 20% | £100.00 | £20.00 | £120.00 | 16.67% |
| 23% | £100.00 | £23.00 | £123.00 | 18.70% |
