Why use a GST calculator?

Manual GST calculations are error-prone, especially when dealing with reverse GST or mixed tax slabs. Our calculators auto-compute CGST, SGST, and total tax so shopkeepers, freelancers, and accountants can invoice accurately every time.

Supported GST rates in India

India uses GST slabs of 0%, 5%, 12%, 18%, and 28%. Intra-state supplies split tax equally into CGST and SGST. Inter-state supplies use IGST at the full rate. All slabs are supported across our GST tools.
