VAT Calculator: Add or Remove VAT
Enter an amount, pick a rate and choose the operation: “remove” if VAT is already included in the price, “add” to put VAT on top. You get the net amount, the tax and the gross total.
How to use
Removing VAT from a £120 gross price at 20%: VAT = 120 × 20 / 120 = £20, net price £100. Use this when a price is quoted “VAT inclusive”.
Adding VAT to a £100 net price at 20%: VAT = 100 × 0.20 = £20, gross total £120. Use this when your price list is quoted before tax.
FAQ
How do I remove VAT from a price? (formula)
VAT = Gross × Rate / (100 + Rate). At 20% that is Gross × 20/120 — or simply divide the gross by 6 to get the VAT portion. The remainder is the net price.
What are the current VAT rates in the UK and EU?
UK: 20% standard, 5% reduced, 0% zero-rated. EU standard rates range from 17% (Luxembourg) to 27% (Hungary); Germany 19%, France 20%, Ireland 23%. Enter any rate in the custom field.
What is the difference between net, VAT and gross?
Net is the price before tax, VAT is the tax itself, gross = net + VAT — the amount the customer actually pays. Mixing them up misprices an invoice by the full tax rate.
Does this work for sales tax or GST?
Yes — the math is identical. Enter your GST rate (e.g. 10% Australia, 15% New Zealand, 18% India) as a custom rate. Note that US sales tax is normally quoted on top of the price, like the “add” mode.
