Add VAT to a net price or remove VAT from a gross price at any rate — showing the net, VAT and gross amounts.
Understanding the vat calculation
This VAT calculator works both ways: add VAT to a pre-tax amount, or strip VAT out of a VAT-inclusive price. Enter the amount and your VAT rate and switch mode as needed.
It’s useful for invoicing, pricing and reclaiming VAT in countries that use it.
The default scenario, worked through
On the values this calculator opens with, the result is $120. Underneath, Net comes out at $100 and VAT at $20. Change any field and every figure updates as you type.
Using the calculator
- Choose “Add VAT” or “Remove VAT”.
- Enter the amount and the VAT rate.
- Read the net, VAT and gross figures.
The calculation
add: VAT = net × rate% · gross = net + VAT
remove: net = gross ÷ (1 + rate%) · VAT = gross − net
Frequently asked questions
How do I add VAT to a price?
Multiply the net price by the VAT rate as a decimal and add it. For 20% VAT on 100, the VAT is 20 and the gross is 120.
How do I remove VAT from a total?
Divide the gross price by 1 plus the rate. For 20% VAT, divide by 1.20 to get the net price.
What VAT rate should I use?
Use your country’s standard or applicable reduced rate. Rates differ by country and product category.
