What is VAT?
VAT, or Value Added Tax, is basically a tax that gets added to the price of most goods and services in the UK. It’s added on at every step of the supply chain, from manufacturing to when your customer actually pays you. If you’re running a business and you’re VAT-registered, you have to charge VAT onto what you sell and send that money to HMRC. The upside? You can reclaim some VAT on your own business purchases, but only if they fit certain criteria, not everything counts.
VAT Rates 2025/26
There are three main VAT rates that apply, depending on the type of goods or services:
- Standard Rate – 20%
The most common rate, applied to most everyday goods and services. For example, electronics, clothing (for adults), and professional services. - Reduced Rate – 5%
This lower rate applies to specific items, such as children’s car seats and household energy bills. - Zero Rate – 0%
Some goods are still taxable but charged at 0%. Examples include most food, children’s clothes, books, and newspapers.
You’ve got to know these rates to make sure your invoices and receipts add up correctly and your budgets aren’t shot.
What is a VAT Calculator
A VAT calculator streamlines handling Value Added Tax, making tax calculations less of a headache, especially for anyone running a business. Instead of fumbling with formulas, you enter your amount, select whether you want to add or remove VAT, and get the results instantly. It breaks it all down: net price, VAT amount, and the full price. No confusion, no wasted time.
It allows you to either:
- Add VAT to a price: If you know the original price of a product or service before tax, the calculator will add the VAT (usually 20% in the UK) to give you the total price including tax.
- Remove VAT from a price: If you know the total price including VAT, the calculator will help you figure out the price before VAT was added.
Here’s what that looks like in practice: Say you’re billing a client for £100, and it’s subject to 20% VAT. The calculator handles the math in two seconds, clearly showing the total as £120. Or reverse it, got a gross amount of £120? The calculator splits that out for you: £100 is the service price, £20 is VAT.
A VAT Calculator is especially helpful for:
- Business owners who need accurate invoices and records.
- Freelancers and contractors who want to work out take-home pay or client charges.
- Shoppers and individuals who want to see how much VAT is included in a purchase.
No more second-guessing or delay. VAT calculators boost efficiency, cut down errors, and makes dealing with VAT much easier.
How to Use Our VAT Calculator UK
Calculating VAT doesn’t need to be a headache. Our VAT Calculator streamlines the process, delivering results in just a few steps. Simply enter your numbers, and let the tool handle the rest. Just follow these easy steps:
- Enter the VAT Rate: The default VAT rate is set to 20%, which is the standard rate in the UK. If you're using a different VAT rate, you can easily change it by entering your desired percentage.
- Input the Value: Enter the amount you want to calculate VAT on. This could be the price of a product or service, either with or without VAT included.
Once you’ve entered these details, the calculator instantly provides two sets of results:
- VAT Included
- Value before VAT added: This is the original price of the item or service before any VAT is applied.
- VAT included amount: This shows the amount of VAT added.
- VAT Excluded
- Value after VAT added: This is the price that includes VAT, but it shows how much the item or service costs after removing VAT.
- VAT excluded amount: This provides the total amount of VAT excluded from the original price.
Examples of When VAT Needs to be Added or Removed
- Adding VAT: If a business sells a product for £100 and the VAT rate is 20%, the total cost will be £120. The business adds £20 as VAT.
- Removing VAT: If a product’s price is £120 including VAT and you want to know the price before VAT, you need to remove the VAT. In this case, you would find that the price before VAT is £100.

Do all businesses need to register for VAT?
No, not all businesses need to register for VAT. You only have to register if your VAT-taxable turnover is above £90,000 in a 12-month period, or if you expect it to go over soon. Smaller businesses below this limit can choose to register voluntarily.

How do you take VAT off an amount?
To take VAT off an amount or to make a reverse VAT calculation, divide the total by 1.20 (for 20% VAT). For example, if the total is £120, dividing by 1.20 gives £100 (the amount without VAT).
