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

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