VAT Calculator

Adding tax is a multiplication; removing it is a division, and that is where most mistakes happen. Both directions are here, each on its own tab.

Good to know

Removing tax is not subtracting the same percentage

If a price includes 20% VAT, the net amount is not «price minus 20%». The tax was added to the smaller number, so you divide: 1200 ÷ 1.2 = 1000, while subtracting 20% would give 960 — a 40-unit error on every invoice.

Rates change, arithmetic does not

The standard rate is 20% in the UK and France, 19% in Germany, 21% in Spain and the Netherlands, 22% in Italy, 23% in Poland. Reduced rates for food, books and medicine differ by country, so take the rate from the invoice rather than from memory.

Frequently asked questions

How do I add VAT to a price?

Enter the net amount and the rate on this tab: the result is the price with tax.

How do I calculate the price without VAT?

Use «Find the original number»: the gross amount first, then 100 plus the rate as the percentage. For 20% that is 120.

How do I get the tax amount alone?

Subtract the net from the gross, or take the percentage of the net directly on the «% of a number» tab.

Are my figures sent anywhere?

No. Everything is calculated in your browser, so invoices and salaries stay on your device.
