How do I calculate GST?
In India, GST is calculated based on the applicable tax rate (0%, 5%, 12%, 18%, or 28%) for specific goods or services, determined by their HSN (Harmonized System of Nomenclature) code for goods or SAC (Service Accounting Code) for services. Here's how to calculate it:
For official information on GST in India, please refer to the Goods and Services Tax Network (GSTN) official website.
From a base price (excluding GST):
- GST amount = Base price × GST rate
- Total price (including GST) = Base price × (1 + GST rate)
Example: Base price = ₹1,000, GST rate = 18%
GST amount = ₹1,000 × 0.18 = ₹180
Total price = ₹1,000 × 1.18 = ₹1,180
From a total price (including GST):
- Base price = Total price ÷ (1 + GST rate)
- GST amount = Total price - Base price
Example: Total price = ₹1,180, GST rate = 18%
Base price = ₹1,180 ÷ 1.18 = ₹1,000
GST amount = ₹1,180 - ₹1,000 = ₹180
