How to Calculate VAT – Adding

This is the equation to add VAT to your figure:

(Original Figure) multiplied by 1. (the VAT percentage) equals New Figure including VAT

For instance, if the rate of VAT is 20% and your figure is £100 the equation would be

100 * 1.20 = 120

Working out the Amount of VAT Added

To calculate the total amount of VAT added, you would need to minus the New Figure including VAT from the Original Figure.

This is the formula:

New Figure Including VATOriginal Figure = Amount of VAT Added

Using figures from the last calculation as an example, we get:

120100 = 20

How to Calculate VAT – Reverse

This is the formula to remove VAT from your figure:

(Original Figure) divided by 1. (the VAT percentage) equals New Figure excluding VAT

For instance, if the rate of VAT is 20% and your figure is £120 the sum would be

120 / 1.20 = 100

Working out the Amount of VAT Removed

In order to calculate the total amount of VAT removed from your original figure, you would need to minus the Original Figure from the New Figure Excluding VAT.

This is the formula:

Original FigureNew Figure Excluding VAT = Amount of VAT Removed

Using figures from the last example, this is the result we get:

120100 = 20
