Calculate GST for any product or service in India. Supports all four GST slabs — 5%, 12%, 18%, and 28% — with automatic CGST and SGST split. Works in both add-tax and reverse modes to extract GST from an inclusive price.
Step 1. Enter the amount — pre-tax or total depending on mode.
Step 2. Select the applicable GST rate — 5%, 12%, 18%, or 28%.
Step 3. Select whether to add GST to the amount or extract GST from an inclusive price.
Step 4. The calculator shows CGST and SGST separately plus the total.
With the default inputs loaded in the form, the calculator produces a starting result you can use as a baseline. Change one field at a time to compare a new scenario.
India's Goods and Services Tax replaced multiple cascading central and state taxes with a unified system. The four primary slabs are 5% (essential items), 12% (standard goods), 18% (most services and goods), and 28% (luxury and sin goods).
CGST (Central GST) and SGST (State GST) each equal half the total GST rate for intra-state supply. For inter-state supply, IGST (Integrated GST) equals the full rate. The split is equal — 9% CGST + 9% SGST for an 18% rated item.
GST input tax credit allows registered businesses to claim back GST paid on inputs against GST collected on outputs, eliminating the cascading effect of earlier indirect taxes.
Non-AC restaurants: 5% GST with no input tax credit. AC restaurants: 5% GST. Hotels with room tariff above Rs.7,500: 18% GST on food and beverages. Check the specific restaurant's invoice for the applicable rate.
CGST = SGST = Total GST ÷ 2. For 18% GST: CGST = 9%, SGST = 9%. For 28% GST: CGST = 14%, SGST = 14%. The split is always equal for intra-state transactions.
No — salary, wages, and employment income are not subject to GST. GST applies to goods and services sold by businesses, not to employment income.
Small businesses with turnover below Rs.1.5 crore can opt for the composition scheme paying a flat rate of 1-5% without input tax credit. Simplifies compliance but prevents claiming credits on purchases.
