VAT formulas and examples
Use these formulas to check the amount added to a tax-free price or removed from a tax-included total.
Add tax
Total = tax-free price x (1 + rate / 100)
Remove tax
Tax-free price = tax-included total / (1 + rate / 100)
Tax amount
Tax = tax-free price x rate / 100
Quick example
Starting from £100, a 20% rate gives £20 in tax and £120 total.
Starting from £120, the tax-free amount is £100 and the tax is £20.
United Kingdom VAT: 20%, 5% and zero rate
The United Kingdom applies Value Added Tax (VAT). The standard rate is 20% and has applied since 4 January 2011. A 5% reduced rate applies to specified supplies, including qualifying domestic fuel and power, and defined supplies can be zero-rated.
Zero-rated supplies remain taxable at 0%, while exempt and outside-the-scope supplies have different VAT and input-tax consequences. The product or service must be classified under HMRC rules.
Pound sterling examples and calculator scope
For a standard-rated price of £100 before VAT, tax is £20 and the total is £120. At the reduced 5% rate, the total would be £105.
The calculator adds or removes the percentage selected. It does not determine the tax point, place of supply, Northern Ireland goods treatment, partial exemption, input-tax recovery, registration or returns. The result is an orientation check, not personalised tax advice.
