How VAT Calculation Works

VAT (Value Added Tax) is added to most goods and services in the UK. This calculator helps you work with VAT in three ways:

  • Add VAT: Enter a net (excluding VAT) price and see the gross (including VAT) total. Formula: Net × 1.20 = Gross
  • Remove VAT: Enter a gross (including VAT) price and see the net amount. Formula: Gross ÷ 1.20 = Net
  • Reverse VAT: Extract the VAT amount from a total. Same calculation as remove, presented to show the VAT portion.

For the 5% reduced rate, use 1.05 instead of 1.20. For zero-rated items, no calculation is needed as VAT is 0%.

Frequently Asked Questions

What is the current UK VAT rate?

The standard UK VAT rate is 20%. There is also a reduced rate of 5% for certain goods like home energy and child car seats, and a zero rate (0%) for items like most food and children's clothing.

How do I calculate VAT quickly?

For 20% VAT: to add VAT, multiply by 1.2. To find just the VAT amount, divide the gross by 6. To remove VAT, divide by 1.2 or multiply by 5/6.
