Free GST Calculator
Need to add or remove GST from a price instantly? Our free GST calculator handles both directions at any rate. Enter a price and choose to add GST (for pricing a product) or remove GST (to find the base price from a GST-inclusive amount), pick from the common Indian GST slabs โ 5%, 12%, 18%, 28% โ or enter a custom rate.
For Indian businesses, toggle between intra-state (CGST + SGST split) and inter-state (IGST) to see exactly how the tax breaks down on your invoice. Every result shows the formula and substituted values, so you can double-check the math or explain it to a client.
