GST Calculator
Add GST to a price, or find out how much GST is included in a price. Choose the rate and whether the sale is within your state or to another state.
₹10,000.00 plus 18% GST is ₹11,800.00, of which ₹1,800.00 is GST.
How GST is calculated
Adding GST to a price
GST = price × rate ÷ 100, and total = price + GST.
Example: ₹10,000 at 18% → GST = ₹1,800, total = ₹11,800.
Removing GST from a GST-inclusive price
Price before GST = inclusive price × 100 ÷ (100 + rate), and GST = inclusive price − price before GST.
Example: ₹11,800 including 18% GST → ₹11,800 × 100 ÷ 118 = ₹10,000 before GST, and ₹1,800 GST.
CGST, SGST and IGST
| Type of sale | GST charged as | Example at 18% on ₹10,000 |
|---|---|---|
| Within the same state or UT | CGST + SGST (or UTGST), half each | ₹900 CGST + ₹900 SGST |
| To another state, or imports | IGST, the full rate | ₹1,800 IGST |
The total GST is the same either way; only the way it is split between the Centre and the states changes.
