How to calculate GST backward (from inclusive amount)?
To find the base amount from GST-inclusive price, use this formula:
Base Amount = GST Inclusive Amount ÷ (1 + GST Rate/100)
Example: If total is ₹1,180 with 18% GST, base amount = ₹1,180 ÷ 1.18 = ₹1,000
Base Amount = GST Inclusive Amount ÷ (1 + GST Rate/100)
Example: If total is ₹1,180 with 18% GST, base amount = ₹1,180 ÷ 1.18 = ₹1,000
What is reverse charge mechanism in GST?
Under reverse charge mechanism, the recipient of goods/services pays GST instead of the supplier. This typically applies to transactions with unregistered dealers, imports, and specific services. The calculation method remains the same - only the liability shifts to the buyer.
Are there any items exempt from GST?
Yes, certain items are completely exempt from GST including fresh fruits and vegetables, unprocessed cereals, milk, curd, natural honey, salt, sindoor, kajal, educational services, and healthcare services. These items don't attract any GST.

How GST is Calculated?
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

0% (necessity items like milk, wheat flour)

5%

How to make calculation of GST 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.
