UK VAT Calculator – Add or Remove VAT Instantly
This UK VAT Calculator is a simple way to work out Value Added Tax for prices in the United Kingdom. It’s useful for businesses, freelancers, online sellers, and anyone who needs quick VAT figures without doing the maths manually.
You can use it to add VAT to a net amount, remove VAT from a total price, or check VAT values when reviewing invoices and receipts. The calculator is set to the standard 20% UK VAT rate by default, which applies to most goods and services.
Instead of relying on formulas or spreadsheets, you just enter an amount, choose what you want to calculate, and the result appears instantly.
If you are new to tax, first understand what is VAT before using this calculator.
How UK VAT Calculation Works
In the UK, VAT is usually charged at 20%. If you are adding VAT, the net amount is multiplied by 1.20. If you are removing VAT, the total price is divided by 1.20.
This calculator applies those rules automatically, which helps avoid mistakes when creating invoices, checking supplier bills, or preparing records for accounting.
Real-World VAT Calculation Examples
Example 1: Small Business Invoice
A freelance web developer charges £750 for a project. After adding VAT, the total comes to £900. This includes £150 VAT, which is shown clearly on the invoice.
Example 2: Expense Reimbursement
An employee submits a hotel receipt for £360 including VAT. Removing VAT shows the original cost was £300, with £60 VAT. That VAT amount can be reclaimed on the next VAT return.
Example 3: E-commerce Product Pricing
An online store lists a product at £89.99 including VAT. Removing VAT shows the net price is £74.99, with £15 VAT included. This helps the seller understand margins before setting prices.

Common UK VAT Calculator Questions
What is the difference between net and gross prices?
The net price is the amount before VAT. The gross price is the final amount after VAT is added. Most consumer prices are shown as gross prices, while business invoices often show both.
When would I need to remove VAT?
Removing VAT is common when reviewing receipts, reclaiming VAT on expenses, or checking whether VAT has been charged correctly on an invoice.
Are there VAT rates other than 20%?
Yes. Some items use reduced or zero rates. The calculator allows you to adjust the VAT rate so you can check different scenarios when needed.
How to Calculate VAT Manually
Adding VAT
Multiply the net price by 1.20 to get the VAT-inclusive amount. The difference between the two is the VAT charged.
Removing VAT
Divide the total price by 1.20 to find the original amount before VAT. The VAT is the difference between the gross and net values.
VAT Removal Calculator (Reverse VAT)
Reverse VAT Calculation Explained
A VAT Removal Calculator, often called a reverse VAT calculator, is used when you already have a total price that includes VAT and need to work out the original amount. This situation comes up frequently when reviewing receipts, supplier invoices, or expense claims.
Instead of guessing the VAT portion, the calculator separates the figures correctly by applying the standard UK VAT formula in reverse. This helps ensure VAT amounts are accurate, especially when preparing records for accounting or tax returns.
Example: If the total invoice amount is £480 including VAT, the calculator shows the net price as £400 and the VAT amount as £80. This makes it clear how much VAT is included in the total and how much can be reclaimed where applicable.
