Calculate GST instantly — add GST to a base price or extract it from a GST-inclusive price.
GST (Goods and Services Tax) in India is charged at a few common slabs — 5%, 12%, 18%, and 28% — depending on the category of goods or services. For sales within the same state, GST is split equally between CGST (Central GST) and SGST (State GST). For sales across states, the full amount is charged as IGST instead.
Add GST takes a base amount and adds GST on top — useful when pricing a product or service. Remove GST takes an amount that already includes GST and works backward to show the base price and tax split — useful when you have a final invoice amount and need the breakdown.
