Frequently Asked Questions
What is GST?
Goods and Services Tax is India's unified indirect tax rolled out in 2017. It replaced multiple central and state taxes with a single levy. Standard slabs are 5%, 12%, 18%, and 28%, plus special rates for gold (3%) and rough diamonds (0.25%).
When do I use exclusive vs inclusive?
Exclusive: when you have a base price and need to add GST on top (e.g., MRP of goods). Inclusive: when the displayed price already includes GST and you need to find the base (e.g., reverse-calculate from invoice).
Does this account for CGST/SGST split?
This shows total GST. In India, intra-state supplies split equally into CGST and SGST; inter-state supplies are IGST. The total GST amount is the same either way.
Is this calculator official?
This is a math calculator using the standard GST formula. For actual tax filing, use a CA or the GSTN portal.
