TL;DR: A UK VAT calculator helps you add or remove Value Added Tax from a price using the correct rates and formulas.
- To add the standard 20% VAT, multiply the net amount by 1.20.
- To remove 20% VAT from a gross total, divide the amount by 1.20.
- The standard VAT rate in the UK is 20% for most goods and services.
- A reduced rate of 5% applies to items like home energy and children"s car seats.
- The zero rate (0%) applies to essentials like most food and children"s clothing.
- Use a reverse VAT calculation to find the original price before tax was added.
How to Calculate VAT in the UK
The basic formula to calculate UK VAT is to multiply the net amount by 1 plus the VAT rate, or to divide the gross amount by the same figure. For the standard 20% rate, you multiply the price before tax (net) by 1.20 to find the total price including tax (gross). To find the original net price from a gross total, you divide by 1.20.
Understanding the terminology is key to using a VAT calculator correctly. The net amount is the price of goods or services before VAT is added. The VAT amount is the tax itself. The gross amount is the final price including the VAT, which is what a consumer typically pays.
The table below shows examples of VAT calculations for the standard 20% rate on common amounts.
| Net Amount (Excluding VAT) | VAT Amount (20%) | Gross Amount (Including VAT) |
|---|---|---|
| £100.00 | £20.00 | £120.00 |
| £250.00 | £50.00 | £300.00 |
| £500.00 | £100.00 | £600.00 |
| £1000.00 | £200.00 | £1200.00 |
Understanding UK VAT Rates
The UK has three different rates of Value Added Tax. The applicable rate depends on the specific goods or services being sold. Using the wrong rate will result in an incorrect tax calculation.
The three VAT rates are:
- Standard Rate (20%): This is the default rate and applies to most goods and services, including electronics, adult clothing, and restaurant meals.
- Reduced Rate (5%): This rate applies to specific items considered to be necessities or beneficial, such as domestic fuel and power, energy-saving materials, and children"s car seats.
- Zero Rate (0%): Zero-rated items are still VAT-taxable, but the rate is 0%. This includes most food (excluding catering and certain items like confectionery), books, newspapers, and children"s clothing.
Some goods and services are VAT exempt, which is different from being zero-rated. Exempt items are outside the scope of VAT entirely, such as postage stamps, financial services, and property transactions. Businesses dealing in exempt items cannot reclaim any VAT on their related expenses.
Adding VAT to a Net Price (Net to Gross)
To add VAT to a net price, you multiply the net amount by (1 + the VAT rate as a decimal). This calculation determines the final gross price that includes the tax. This is the most common calculation for businesses setting prices for their products or services.
The formula is: Net Amount × (1 + VAT Rate %) = Gross Amount.
For example, to add the standard 20% VAT to a net price of £500:
- Step 1: Convert the percentage to a decimal: 20% becomes 0.20.
- Step 2: Add 1 to the decimal: 1 + 0.20 = 1.20.
- Step 3: Multiply the net amount by this figure: £500 × 1.20 = £600.
- The gross amount is £600, and the VAT amount is £100 (£600 - £500).
Removing VAT from a Gross Price (Reverse VAT Calculation)
To remove VAT from a gross price, you divide the gross amount by (1 + the VAT rate as a decimal). This process, often called a reverse VAT calculation, is used to find the original net price and the amount of tax included in a total. It is useful for accounting and claiming business expenses.
The formula for this is: Gross Amount / (1 + VAT Rate %) = Net Amount.
For instance, to find the net price and VAT from a gross total of £300 that includes 20% VAT:
- Step 1: Convert the percentage to a decimal: 20% becomes 0.20.
- Step 2: Add 1 to the decimal: 1 + 0.20 = 1.20.
- Step 3: Divide the gross amount by this figure: £300 / 1.20 = £250.
- The net amount is £250. The VAT amount is the difference: £300 - £250 = £50.
