🧾 VAT / GST Calculator
To add VAT, multiply the net price by (1 + rate); to remove it, divide the gross price by (1 + rate). At 20%, £50 net becomes £60 gross, and £60 gross is £50 net. Enter your values below — results update instantly, entirely on your device.

How the vat / gst calculator works
Adding: gross = net × (1 + rate/100), and the tax is net × rate/100. Removing: net = gross ÷ (1 + rate/100), and the tax is gross − net. "Remove VAT" is the reverse calculation people most often get wrong — you divide, you don't subtract the percentage.
Example: Add 20% to 50 → tax 10, gross 60. Remove 20% from 60 → net 50 (60 ÷ 1.20), not 48.
Common standard rates: UK & France 20%, Germany 19%, Ireland 23%, Australia & New Zealand GST 10% and 15%, India GST commonly 18%, Singapore GST 9%. Rates and reduced-rate categories change — confirm the current rate for your country and product before relying on a figure. Nothing you type is sent anywhere.
Frequently asked questions
How do I remove VAT from a price?
Divide the VAT-inclusive price by 1 plus the rate as a decimal. To remove 20% VAT from 60, compute 60 ÷ 1.20 = 50. Subtracting 20% of 60 (giving 48) is the common mistake — it's wrong because the 20% was added to the smaller net figure, not the gross.
What is the difference between VAT and GST?
They work the same way arithmetically — a percentage consumption tax added to a price. "VAT" is used in the UK, EU and many other countries; "GST" (goods and services tax) is the term in Australia, New Zealand, India, Singapore and Canada. This tool handles either at any rate.
What VAT rate should I use?
Use your country's current standard rate unless the product falls under a reduced or zero rate. Because rates and categories change, treat the presets in the notes as a starting point and verify the official current rate.
