VAT calculator: add or remove VAT at any rate
Enter a price and a rate. The VAT calculator shows the net amount, the VAT and the gross total. Use Price before VAT to add VAT, or Price including VAT to take it out (reverse VAT). It works for UK VAT at 20%, the EU standard rates in the table, the UAE at 5%, Saudi Arabia at 15%, or any rate you type. Your numbers stay in this tab.
VAT formulas
| Task | Formula | Example at 20% |
|---|---|---|
| Add VAT | Gross = net × (1 + rate) | £100 → £120 (VAT £20) |
| Remove VAT | Net = gross ÷ (1 + rate) | £120 → £100 (VAT £20) |
| VAT inside a gross price | VAT = gross − gross ÷ (1 + rate) | £60 → VAT £10 |
At 5% (UAE), AED 1,050 including VAT is AED 1,000 net plus AED 50 VAT.
About the rate table
The table lists standard rates that are widely published for the UK and EU countries. Reduced, super-reduced and zero rates are not listed. Rates change, and businesses can be on special schemes, so confirm the rate with the tax authority before you invoice. This is guidance, not tax advice.
