What is a GST Calculator?

A GST Calculator is a free online tool to calculate Goods and Services Tax (GST) in India. It determines the base amount, tax rates, CGST, SGST, IGST, and final values instantly.

How is GST calculated?

For GST Exclusive values, multiply the base amount by the tax rate: GST = Amount * (Rate/100). For GST Inclusive values, calculate tax using: GST = Amount - (Amount / (1 + Rate/100)).

What is the difference between CGST, SGST and IGST?

CGST (Central GST) and SGST (State GST) apply to trade within a single state (Intra-State). IGST (Integrated GST) applies to supply chains between different states (Inter-State).
