GST Exclusive

When the amount is GST exclusive, GST is calculated on the original amount and added to it.

GST Amount
Original Amount × GST Rate ÷ 100
Total Amount
Original Amount + GST Amount

GST Inclusive

When the amount is GST inclusive, the entered amount already contains GST. The calculator separates the actual amount and GST amount.

Actual Amount
Inclusive Amount ÷ (1 + GST Rate ÷ 100)

GST Calculation Example

For an amount of ₹2,000 with an 18% GST rate:

Actual Amount ₹2,000
GST Rate 18%
GST Amount ₹360
Total Amount ₹2,360
