About the VAT Calculator
This VAT calculator works in both directions. In Add mode, enter a net price and the tax rate to see the VAT amount and the gross total your customer pays. In Remove mode, enter a gross, VAT-inclusive price and the calculator backs the tax out to reveal the underlying net figure — the division-based step that people most often get wrong when working by hand.
The rate defaults to 20% but is fully editable, so it fits any country's standard or reduced rate, and the identical math applies to GST and sales tax. Freelancers use it when drafting invoices, bookkeepers when reconciling receipts, and shoppers when comparing cross-border prices. All three figures — net, VAT and gross — appear together, calculated instantly and privately in your browser.

Frequently asked questions
How do I add VAT to a price?
Multiply the net price by (1 + rate ÷ 100). At the 20% preset, a 100.00 net price carries 20.00 of VAT for a 120.00 gross total. The calculator's Add mode shows all three numbers the moment you enter the net amount.
How do I remove VAT from a gross price?
Divide the gross amount by (1 + rate ÷ 100). A 120.00 receipt at 20% VAT contains a net of 120 ÷ 1.20 = 100.00 and 20.00 of tax. Remove mode performs this division for you and separates the tax from the underlying price instantly.
Why can't I just subtract 20% to remove VAT?
Because the 20% was charged on the smaller net figure, not on the gross. Subtracting 20% from 120.00 gives 96.00 — wrong by 4.00 — while dividing by 1.20 correctly returns 100.00. This is the single most common VAT mistake, and it always overstates the tax.
Which VAT rate should I enter?
Use the rate that legally applies to your product and country. Standard rates range from around 5% to 27% worldwide — for example 20% in the UK, 19% in Germany, 17% in Luxembourg — and many countries add reduced rates for food, books or energy. The rate field accepts any value.
Does this work for GST and sales tax too?
Yes. GST in countries like Australia, Canada, India and New Zealand uses exactly the same add-and-extract arithmetic, and US sales tax additions work the same way in Add mode. Just type the applicable percentage into the rate field and read the results as usual.
