VAT Calculator
Add VAT to a net price or remove VAT from a gross price — using the standard UK and EU rates, right in your browser.
What is a VAT calculator?
VAT (Value Added Tax) is a consumption tax charged at every stage of the supply chain and passed on to consumers in the final price. A VAT calculator lets you either add VAT to a net (pre-tax) amount, or take the VAT figure back out of a gross (tax-inclusive) price.
Adding VAT is simple: multiply the net amount by 1 plus the rate. To remove VAT, you divide the gross amount by 1 plus the rate, then subtract to find the VAT that was included. In the UK the standard rate is 20%, alongside a 5% reduced rate for some goods and services, and 0% for zero-rated essentials like most food and children's clothing. Across the EU rates differ by country, usually between 17% and 27%.
Because the calculation runs on your device, your figures never leave your browser.
How to use
- Enter the amount you are working with.
- Choose the VAT rate — or enter a custom rate if your currency or country differs.
- Pick Add VAT or Remove VAT, then click Calculate VAT to see the gross or net total and the VAT amount.
Example
A product costs £100 net and the standard UK rate is 20%. To add VAT: 100 × 1.20 = £120 gross. The VAT charged is £20. To work backwards from a gross price of £120: 120 ÷ 1.20 = £100 net, meaning £20 of that price is VAT.
Common use cases
- Working out the selling price of a product or service.
- Reclaiming the VAT included in your expenses.
- Preparing invoices and quoting clients.
- Comparing prices before and after VAT for budgeting.
Pro tips
- For a price that already includes VAT, always divide by 1 + the rate — never just subtract the percentage.
- Round the net price to two decimals before adding VAT to avoid rounding errors.
- Keep the same rate for both adding and removing to avoid confusion.
- Remember some goods are zero-rated (0%) rather than exempt, which affects whether you can reclaim VAT.
