What is the VAT Calculator?

VAT trips people up in both directions: adding it to a net price, and pulling it back out of a total that already includes it. Get the second one wrong — dividing by the rate instead of one-plus-the-rate — and your figures are off. This calculator handles both cleanly, at any rate.

It runs in your browser and shows the net, the VAT and the gross together.

What does this tool do?

In Add VAT mode you enter a net (VAT-exclusive) amount and a rate, and it returns the VAT and the gross total. In Remove VAT mode you enter a VAT-inclusive total and it works backwards to the net price and the VAT it contains. Preset buttons cover common rates, or type any custom rate.

It's the quick, correct way to handle VAT-inclusive and VAT-exclusive prices.

Tips

To remove VAT, the tool divides by one-plus-the-rate (e.g. 1.20 for 20%) — not by the rate itself, a common error.
Use your own country's rate; VAT differs widely, so don't assume 20%.
For invoices, show the net, the VAT and the gross separately — this tool gives you all three.
Rounding can leave a penny difference on large totals; round the final gross, not each line.
VAT and US sales tax aren't the same system — use the sales tax tool for US tax added at checkout.

Common mistakes to avoid

Removing VAT by dividing by the rate

Fix: Divide the gross by one-plus-the-rate (1.20 for 20%), which this tool does automatically.

Assuming a single VAT rate

Fix: Rates vary by country and product — enter the correct one.

Confusing VAT with US sales tax

Fix: They work differently; use the sales tax tool for US-style tax.

Rounding every line

Fix: Round the final total once to avoid accumulating penny errors.
