What Is a GST Calculator?
A GST Calculator is an online utility that helps you compute GST in two main modes:
GST Exclusive: You have a base amount and you want to add GST to it
GST Inclusive: You have a total amount including GST and want to extract how much GST is inside it
From those you get:
GST Amount
Base Price (if inclusive)
Total Price (if exclusive)
Example Calculations
GST Exclusive Example
Base Amount: ₹1,000
GST Rate: 18%
GST Amount = 1,000 × 0.18 = ₹180
Total Price = 1,000 + 180 = ₹1,180
GST Inclusive Example
Total Amount: ₹1,180
GST Rate: 18%
GST Inside = (1,180 × 18) ÷ 118 = ₹180
Base Price = 1,180 − 180 = ₹1,000
