About GST Calculator

The GST (Goods and Services Tax) Calculator is an indispensable tool for businesses, freelancers, and consumers in India. GST replaced multiple indirect taxes with a unified tax system effective July 1, 2017, and understanding how to calculate it correctly is essential for pricing, invoicing, and tax compliance.

GST Rates in India

India has four main GST rate slabs: 5% (essential items like food grains, medicines), 12% (processed foods, computers), 18% (most goods and services — the standard rate), and 28% (luxury items, automobiles). Some items are zero-rated or exempt.

CGST, SGST, and IGST

For intra-state transactions, GST is split equally into CGST (Central GST) and SGST (State GST). For inter-state transactions, IGST (Integrated GST) applies. Our calculator shows the CGST and SGST breakdown assuming intra-state supply.

GST Inclusive vs Exclusive

GST Exclusive pricing means GST is added on top of the base price — common in B2B invoicing. GST Inclusive pricing means the displayed price already includes GST — common in retail. To extract GST from an inclusive price: Base = Inclusive Price ÷ (1 + Rate/100).
