How to add tax to a price

This is the calculation you need to use when:
you know a price before tax (the Net price)
but want to find out the price after tax (the Gross price).

If we assume that tax is at a rate of 15%...

Net price

multiplied by

1.15

= Gross price

Price before tax

multiplied by

1.15

= Price after tax

eg. 150.00

multiplied by

1.15

= 172.50

In the equation above, 1.15 is the multiplier. To get the multiplier, we need to convert the tax rate into a fraction by dividing it by 100 and then add the resulting fraction to 1.

So, if we assume that VAT is at a rate of 15%,
we will need to divide 15 by 100, giving 0.15, then add 1.
Thus the multiplier is 0.15 +1 = 1.15

So now let's assume that a tax is at a new rate of 20%...

First, get the multiplier :
20 / 100 = 0.20
0.20 + 1 = 1.20

The multiplier is 1.20

So...

Net price

multiplied by

1.20

= Gross price

Price before tax

multiplied by

1.20

= Price after tax

eg :

     

100

multiplied by

1.20

= 120.00

100 + Tax

= 120.00 inc Tax
