How To Calculate GST On Inclusive And Exclusive Prices

Learn how GST-inclusive and GST-exclusive calculations work, and when to use CGST, SGST, or IGST splits.

GST exclusive price calculation

For GST-exclusive pricing, tax is added on top of the base amount. This helps estimate the invoice total after applying the selected GST rate.

GST inclusive price calculation

For GST-inclusive pricing, the taxable value is back-calculated from the final price. This helps identify how much of the selling price already represents GST.

CGST, SGST, and IGST explained

In intrastate transactions, GST is usually split equally into CGST and SGST. In interstate transactions, IGST is commonly applied as a single tax amount.
