What the two labels mean
A GST-exclusive price is the value before GST. Tax is added at the end. A GST-inclusive price already contains the GST component, so the tax has to be backed out to find the pre-tax value. Neither is universally better; the right choice depends on how you market and document the transaction.
Use the correct formula
For an exclusive price, tax equals base price × GST rate, and final price equals base plus tax. For an inclusive price, base price equals final price ÷ (1 + GST rate). The tax is the difference between the final price and the base price.
Quote and discount with the same convention
If a customer sees “₹1,180 including GST” and a salesperson later offers a 10% discount, specify whether the discount applies to the displayed total or to the pre-tax base. Document the approach in the quotation. Consistency helps finance teams reconcile the order, invoice and payment.
Do not choose the rate from a calculator menu
A calculator can handle arithmetic only after a valid rate and treatment are chosen. Classification, exemptions, place of supply, reverse charge and scheme status may affect the final outcome. When a pricing decision is material, obtain advice before publishing a rate.
