Calculate VAT backwards or forwards and remove VAT from a number
Reverse UK VAT Calculator or How to calculate UK VAT Backwards, Forwards or in Reverse
If you are running an online shop, you will often have to enter your prices excluding VAT in the admin area of your website.
On the front end of your website you may want this to be ‘clean price’ or a ’rounded price’ for your customers to view (e.g. £20.00, £25.00 or £100.00).
You may also want this price to include VAT.
The Vat Calculator allows you to add a clean rounded figure and then calculate the VAT portion for you.
You can then add the price to your shop knowing that the figure displayed on the front end will be a nice and clean ‘vat-inclusive’ figure.
This gives your customer a clean price on the front end of your website with VAT included.
Adding 20% VAT is a straightforward calculation but reverse VAT can be tricky
Adding 20% VAT to a price is easy, (simply multiply by 1.2)
e.g. to add 20% VAT to £100.00 simply multiply £100.00 x 1.2 = £120.00
But calculating what is the VAT portion of £120.00 is not as simple as taking 20% of £120.00 (which leaves £96.00).
Notice how adding 20% VAT is not the same as removing 20% VAT
Calculating VAT ‘backwards’ or calculating VAT in ‘reverse’ can sometimes be tricky – as you can’t simply take 20% off the VAT included price to calculate the VAT portion.
To help you out we have developed this handy little VAT Calculator, that calculates VAT ‘backwards’ or ‘forwards’ or in ‘reverse’, if you prefer.
How to use the VAT Calculator
Simply enter the amount you want to work with, select whether that amount already includes VAT or not and hey presto! – you have VAT Calculated forwards or backwards.
Simply tick or untick the ‘Does this include VAT?’ box, to show the figure as VAT included or VAT excluded.
How to remove VAT from a sum manually
Divide the gross amount by (1 + VAT %)
VAT Rate is 20% so divide by 1.20
£100.00 divided by 1.20 = £83.33
Subtract £83.33 from £100.00 = £16.67
Therefore £16.67 is the VAT Amount on an item sold for £100.00.
If you try this sum on the VAT Calculator you will see that it is correct.

How does VAT Work?
When a business becomes VAT registered, it must charge a further 20% on all sales (or whatever the vat rate is), when the invoice is paid that is when VAT is deducted. Businesses must also pay their VAT Return every 3 months to HMRC, before this is paid the business will take away any VAT that is for their suppliers.

There are 3 basic rates of VAT in the United Kingdom which are applied to goods and services.
The Standard VAT rate in the UK is 20%
This is the VAT rate most commonly used in the UK and covers most goods and services.

The UK government has also introduced a 5% VAT rate from 8th July 2020 to 12 January 2021 as a temporary measure.
Who does the new 5% VAT Rate apply to?
The new 5% rate applies to businesses that make ‘supplies of admissions’ that are currently taxable at the standard rate.

And similar cultural events and facilities.
The rate is aimed at admission fees only but can include incidental items that are included in the admission fees.
