GST Exclusive vs. GST Inclusive – What’s the Difference?

GST Exclusive

The entered amount is before GST. The GST amount is calculated and added to it to get the final price.

GST Inclusive

The entered amount already includes GST. Our calculator will extract the GST and show the base amount and tax amount separately.

Formula Used in Our GST Calculator

For GST Exclusive:

Total Amount = Original Amount + (Original Amount × GST%)

For GST Inclusive:

Base Amount = Total Amount ÷ (1 + GST%)

GST Amount = Total Amount - Base Amount

Example Calculations

Example 1: GST Exclusive

Original Amount = ₹1,000
GST Rate = 18%
Total = ₹1,180 (₹1,000 + ₹180 GST)

Example 2: GST Inclusive

Total Amount = ₹1,180
GST Rate = 18%
Base = ₹1,000, GST = ₹180
