Use this free VAT calculator to add VAT to a net price or remove VAT from a VAT-inclusive total in seconds. Enter the VAT rate, choose whether you want to add or subtract tax, and the tool will instantly show the gross amount, net amount, and VAT amount.
It is especially useful for freelancers, ecommerce sellers, small businesses, invoice checks, quotes, and quick pricing decisions. If you also need help with simple percentage math, discounts, or markups, our Percentage Calculator is a good companion tool.
Need to add 20% VAT to a service invoice, remove 21% VAT from a final price, or double-check whether a supplier total is correct? This calculator is built for exactly that kind of quick real-world tax math.
What this VAT calculator helps you do
VAT math usually comes down to two practical jobs:
- add VAT to a net amount to get the gross selling price
- remove VAT from a VAT-inclusive total to find the pre-tax amount and the tax portion
This tool is useful when you want to:
- price a product or service before sending a quote
- check how much VAT is included in a final invoice total
- compare different VAT rates such as 20%, 21%, or 23%
- separate tax from revenue when reviewing sales
- sense-check marketplace or supplier totals quickly
How this VAT calculator works
The calculator uses the VAT rate you enter and applies one of two simple operations.
If you add VAT
You start with a net amount and add the selected VAT percentage.
Formula:gross price = net price × (1 + VAT rate)
Example:
- net price: €100
- VAT rate: 20%
- gross price: €120
- VAT amount: €20
If you subtract VAT
You start with a gross amount that already includes VAT and work backwards.
Formula:net price = gross price ÷ (1 + VAT rate)
Example:
- gross price: €121
- VAT rate: 21%
- net price: €100
- VAT amount: €21

Practical VAT examples
1) Add VAT to a net price
If your service fee is €250 before tax and you charge 21% VAT, the calculator shows the final gross amount your customer will pay.
2) Remove VAT from a final price
If an invoice total is €242 including 21% VAT, you can work backwards to see the original net amount and the tax part.
3) Compare rates across countries or situations
If you sell in different markets, you may need to compare what happens at 20%, 21%, or another local VAT rate before setting a final price.
4) Check supplier or marketplace math
When a supplier sends a total that already includes VAT, the calculator helps you confirm whether the tax amount and base value make sense.
5) Plan margins more clearly
If you sell online, separating net revenue from tax collected gives you a cleaner picture of real margin before fees and costs.
If you also sell on Etsy, our Free Etsy Fee & Profit Calculator can help you see how VAT, fees, and costs affect the final result.
VAT calculator FAQ
How do I calculate VAT backwards from a final price?
Take the VAT-inclusive total and divide it by 1 + VAT rate. That gives you the net amount. The VAT amount is the difference between gross and net. This calculator does that instantly for you.
What is the difference between VAT-inclusive and VAT-exclusive pricing?
VAT-exclusive pricing shows the price before tax. VAT-inclusive pricing shows the final amount after VAT has been added. If you want a clearer breakdown, read VAT Inclusive vs VAT Exclusive Pricing Explained.
Is VAT the same as sales tax or GST?
Not exactly, but the math is often similar for quick calculations. This tool can still help you add or remove a percentage-based tax from a price.
Can I use this calculator for EU cross-border pricing?
It is useful for quick math and rough comparisons, but it does not replace country-specific VAT rules, invoicing rules, OSS treatment, or accounting advice.
Can I enter decimal VAT rates?
Yes. You can use decimal rates such as 7.5% or 15.75% if needed.
Is this tool only for businesses?
No. It is also useful for buyers who want to check invoice totals, understand included tax, or compare pre-tax and final prices.
