VAT Formulas
Adding VAT
To add VAT to a net amount:
- VAT = Net × Rate
- Gross = Net × (1 + Rate)
- Example: 100 × 1.20 = 120 (20%)
Removing VAT
To separate VAT from a gross price:
- Net = Gross ÷ (1 + Rate)
- VAT = Gross − Net
- Example: 120 ÷ 1.20 = 100 (20%)
Standard Rates by Country
- United Kingdom: 20% (reduced 5%)
- Germany: 19% (reduced 7%)
- France: 20% (reduced 10% / 5.5%)
- Spain: 21% (reduced 10% / 4%)
- Ireland: 23%
- Türkiye: 20% (reduced 10% / 1%)
Common Mistake
Subtracting 20% from a gross price is WRONG.
- Wrong: 120 − (120 × 20%) = 96
- Right: 120 ÷ 1.20 = 100
- VAT is ≈ 16.67% of the gross, not 20%
Frequently Asked Questions
How is VAT calculated?
To add VAT, multiply the amount by (1 + rate); for example, for 20% multiply by 1.20. To remove VAT from a gross price, divide the price by (1 + rate).
How do I remove VAT from a gross price?
Choose the 'Remove VAT' mode and enter the VAT-inclusive amount; the tool calculates the net (excluding VAT) amount and the VAT it contains. The formula is Net = Gross ÷ 1.20 for a 20% rate.
Why can't I just subtract 20% from the gross price?
Because VAT is added on top of the net amount, not on top of the gross. Subtracting 20% from 120 gives 96, which is wrong; the correct net is 100. VAT makes up about 16.67% of a 20%-inclusive gross price.
Which VAT rate should I use?
It depends on your country and product. The UK standard rate is 20% with a 5% reduced rate; Germany uses 19%, France 20%, Spain 21%. Use the preset buttons or type your own rate.
Can I enter a custom VAT rate?
Yes. Type any rate into the rate box next to the preset buttons and the result updates instantly — useful for 19%, 21%, 23% or any other rate.
Are the amounts I enter stored?
No. All calculations run in your browser; values are only kept locally on your device for convenience.
