Formula to calculate GST on a price without GST
To calculate the GST in this case, the following formula should be used:
Practical example of GST calculation at 5%
That is, if you have a product whose value is $240 without GST and with a 5% GST rate, the formula would look like this:
The product price must be multiplied by the GST percentage, and that number divided by 100. In this case, it would give $12. So the GST amount would be $12.
Another alternative would be to divide 5% by 100, resulting in 0.05, and multiply this by $240, resulting in $12 in the same way.
Finally, to add GST to a price, add the base price of the product, for example, $240, plus the calculated GST of $12, giving a final result of $252.
