Frequently Asked Questions (FAQ)
How do I add GST to a price?
GST amount = price × rate ÷ 100, and the final price = price + GST. For example, ₹1,000 at 18% GST gives ₹180 GST and a final price of ₹1,180.
How do I remove GST from a GST-inclusive price?
Original price = inclusive price × 100 ÷ (100 + rate). For example, ₹1,180 including 18% GST has an original price of ₹1,000 and ₹180 of GST.
What are CGST, SGST and IGST?
For sales within one state, GST is split equally into CGST (Centre) and SGST (State), for example 18% = 9% + 9%. For sales between states, the full rate is charged as IGST.
Which GST rate should I use?
Since 22 September 2025, most goods and services fall under 5% or 18%, with 40% for a few items, and a few special items have rates like 3%. The right rate depends on your product or service, so check the official rate list or your invoice. Use the custom box for any other rate.
