How to calculate GST in India?
Adding GST (Exclusive to Inclusive)
Formula: GST Amount = (Original Cost × GST %) / 100
Example: If a product costs ₹1000 and the GST rate is 18%, the GST amount is ₹180. The total price becomes ₹1180.
Removing GST (Inclusive to Exclusive)
Formula: GST Amount = Original Cost - (Original Cost × [100 / (100 + GST %)])
Example: If the total price is ₹1180 and includes 18% GST, the original cost before tax was ₹1000.
