VAT / Sales Tax Calculator
Add or remove VAT / sales tax from any amount.
Adding and removing VAT
To add VAT: gross = net × (1 + rate/100). To remove VAT from a gross price: net = gross ÷ (1 + rate/100) — a common mistake is subtracting the rate directly, which gives the wrong answer. This tool does both directions correctly at any rate.
Frequently asked questions
How do I take 20% VAT off a price?
Divide the gross price by 1.20. £120 gross ÷ 1.2 = £100 net, so the VAT portion is £20.
