Find the price before tax and the tax included in a total
VAT in the United Kingdom:
The standard UK VAT rate is 20% for most goods and services.
A reduced rate of 5% applies to some items, while some supplies are zero-rated or exempt.
This calculator starts at 20%, but you can change the rate at any time to match your receipt or country.
Using this calculator outside the UK:
Scotland follows the same UK VAT system, so the standard rate is also 20%.
Australia calls its tax GST and uses a standard rate of 10%.
You can replace the starting rate with the VAT or GST rate shown on your own receipt.
UK example:
If the VAT-inclusive total is £1,200 and the VAT rate is 20%, the price before VAT is £1,000 and the VAT amount is £200.

How the calculation works
Price before tax = Total including tax ÷ (1 + Tax rate ÷ 100)
Tax amount = Total including tax − Price before tax
Note: Tax rates and exemptions depend on the country, location, product and service. Check the rate on your receipt or invoice before using the result for accounting or tax reporting.
The UK standard VAT rate of 20% and Australian GST rate of 10% were checked in July 2026.
