What is the Formula for Calculating GST?
GST is calculated by multiplying the base price by the GST rate. There are two main scenarios:
1. Adding GST to Base Price
GST Amount = (Base Price × GST%) / 100
Total Price = Base Price + GST Amount
2. Extracting GST from Total Price
GST Amount = Total Price - [Total Price × (100 / (100 + GST%))]
Example: If the original cost is ₹5,00,000 and the GST rate is 12%, the GST amount will be ₹60,000 (12% of 5,00,000).
