What's the difference between CGST, SGST and IGST?

CGST and SGST apply equally on intra-state sales (each half of the GST rate). IGST is the full GST rate charged on inter-state sales and is collected by the Centre and shared with the destination state.

Which products attract which GST rate?

Broadly: essentials at 5%, standard goods/services at 12% or 18%, and luxury/sin goods at 28%. Always confirm the HSN/SAC code rate on the official CBIC website.

Is GST included in MRP?

Yes — MRP (Maximum Retail Price) is always GST-inclusive in India. Use 'Remove GST' to extract the base price from an MRP.

Are there items exempt from GST?

Yes — many essentials (fresh fruit, milk, salt, basic education, healthcare services) are exempt or zero-rated. Always check the latest CBIC notification.

What is GST?

GST (Goods and Services Tax) is India's unified indirect tax. For intra-state sales the rate is split equally between CGST (Central) and SGST (State). For inter-state sales the full rate is charged as IGST instead.

Formula

Add GST:    GST = Base × rate / 100
            Total = Base + GST

Remove GST: Base = Total / (1 + rate/100)
            GST = Total − Base

CGST = SGST = GST / 2  (intra-state)

How to use this calculator

Pick "Add GST" to compute the total payable on a pre-tax amount, or "Remove GST" to extract the base amount from a tax-inclusive price. Choose the GST rate that matches the product or service category.
