GST (Goods and Services Tax) is a value-added tax applied to most goods and services in India and several other countries. This GST calculator handles both directions: add GST to a base (net) amount to find the gross price, or remove GST from a gross amount to find the original net price and the tax component. Enter the amount, pick the GST slab (commonly 5%, 12%, 18%, or 28% in India, or any custom rate), and the calculator shows the tax amount and the final total. For intra-state transactions it also splits the tax into CGST and SGST halves, which is exactly what you need when preparing an invoice. Whether you are a freelancer pricing a service, a shop owner issuing bills, or a buyer checking a quote, this removes the guesswork and the manual arithmetic. It runs entirely in your browser and stores nothing you enter.
Add or remove GST from an amount with standard India slabs and CGST/SGST or IGST breakdown.
Uses standard GST math for exclusive and inclusive amounts. CGST/SGST splits assume equal halves for intra-state supply; verify rates and rules for your jurisdiction.
