20% VAT Calculator

Calculating VAT ‘backwards’ and ‘forwards’ or needing to remove VAT from a number

20% Vat Calculator


Reverse UK VAT Calculator or How to calculate UK VAT Backwards, Forwards or 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.

You may also want this price to include VAT.

The online UK vat calculator allows you to add a clean rounded figure and then calculate the VAT portion for you. This gives you a clean price on the front end of the website with VAT included.

Adding 20% VAT is a straightforward calculation

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 ‘backwardsor 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 Online 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 £83.00 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 Calculator you will see that it is correct.
