How the Calculation Works

GST Exclusive Formula (+ Add)

GST Amount = (Base Price × GST%) / 100

Used when you know the raw manufacturing or service cost and need to find out how much tax to collect from the buyer.

GST Inclusive Formula (- Remove)

Base Price = Total Price / (1 + (GST% / 100))

Used when you have a final retail price (MRP) and need to isolate the clean revenue from the tax liabilities.
