Question 1

How does the GST calculator work?

Accepted Answer

Enter the amount, select the applicable GST rate (5%, 12%, 18%, 28%), and choose whether the amount is GST-exclusive (add GST) or GST-inclusive (extract GST). The tool instantly calculates the base value, CGST/SGST or IGST, and final total.

Question 2

What is the difference between CGST, SGST, and IGST?

Accepted Answer

Intra-state sales split GST equally between CGST (Central GST) and SGST (State GST). Inter-state sales charge the entire tax as IGST (Integrated GST).

Question 3

Can I use this for both products and services?
