Understanding GST and Its Calculation
Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services in India. Our GST calculator helps businesses and individuals calculate accurate GST amounts, whether adding GST to base prices or removing GST from inclusive amounts. The calculator supports all GST rates including 5%, 12%, 18%, and 28%, along with custom rates for specific goods and services.
GST Rates and Slabs 2025
GST in India has four main tax slabs: 5% for essential items like food grains and medicines, 12% for processed foods and textiles, 18% for most goods and services including IT services, and 28% for luxury items and automobiles. Our GST calculator includes preset buttons for these common rates and allows custom rate input for specific scenarios like 0.25% for precious metals or 3% for gold.

CGST (Central GST) and SGST (State GST) apply to intrastate transactions, each at half the total GST rate. IGST (Integrated GST) applies to interstate transactions at the full GST rate. Our calculator shows the appropriate breakdown based on your transaction type.
