How to calculate GST?

GST can be calculated simply by multiplying the Taxable amount by GST rate. If CGST & SGST/UTGST is to be applied then CGST and SGST both amounts are half of the total GST amount.

GST = Taxable Amount  x  GST Rate

If you have the amount which is already including the GST then you can calculate the GST excluding amount by below formula

GST excluding amount = GST including amount/(1+ GST rate/100)

For example: GST including amount is Rs. 525 and GST rate is 5%.

GST excluding amount = 525/(1+5/100) = 525/1.05 = 500

What is the percentage of GST in India?

GST rates are as under

  • 0% (necessity items like milk, wheat flour)
  • 0.25% (rough diamonds)
  • 3%  (gold, silver etc.)
  • 5%
  • 12%
  • 18%
  • 28%

Most of the goods fall in the category of 5%, 12% and 18%, while most of the services fall in the category of 18%. GST of 28% is applicable on some items like cement, car, tobacco. There is also a Cess which is applicable only on a handful of goods like car, tobacco, pan masala.

There are also goods/services on which GST is applicable at NIL rate or which are exempted. Read our article regarding Difference between NIL rate, 0% GST rate and exempted goods/services.

How to make calculation in case of reverse charge?

In the case of reverse charge also, the calculation will be same. For example, you have purchased goods worth Rs. 5,000 from a person and you are required to pay GST on reverse charge at the rate of 18%. So you have to pay a GST on reverse charge of Rs. 900 (5,000 x 18%). If CGST & SGST is to be levied then CGST & SGST of Rs. 450 each is to be paid.
