How to calculate GST on MRP?

To extract GST from MRP (inclusive price), use the formula: GST = MRP - (MRP x 100 / (100 + GST%)). For example, if MRP is Rs 1,180 at 18% GST, the base price is Rs 1,000 and GST is Rs 180.

What is the difference between CGST, SGST and IGST?

For sales within the same state, GST is split equally into CGST (Central GST) and SGST (State GST). For inter-state sales, IGST (Integrated GST) is charged at the full rate. The total tax amount remains the same.

What are the current GST rates in India?

India has multiple GST rate slabs: 0% (essential goods), 0.25% (rough diamonds), 3% (gold/silver), 5% (essential services, transport), 12% (processed food, business class), 18% (most services, electronics), and 28% (luxury goods, cars). Some items attract compensation cess above 28%.

How to calculate reverse GST?

To find the original price from a GST-inclusive amount: Base Price = GST-inclusive Price / (1 + GST Rate/100). For example, Rs 1,180 at 18% GST: Base Price = 1180 / 1.18 = Rs 1,000.

Is GST inclusive and exclusive the same?

No. GST-exclusive means the price does not include tax - GST is added on top. GST-inclusive means the price already contains the tax. The base price and tax amount are different in each case for the same listed price.

How GST is Calculated

Adding GST (Exclusive)

When the price does not include GST, the tax is added on top.

GST Exclusive Formula

GST Amount = Price x (GST Rate / 100)
Total Price = Price + GST Amount

For example, a product priced at Rs 10,000 with 18% GST: GST = Rs 1,800, Total = Rs 11,800.

Removing GST (Inclusive / Reverse)

When the price already includes GST:

GST Inclusive Formula

Base Price = Total Price / (1 + GST Rate / 100)
GST Amount = Total Price - Base Price

For example, a product with MRP Rs 11,800 at 18% GST: Base = Rs 10,000, GST = Rs 1,800.

CGST, SGST & IGST Explained

CGST (Central GST): Collected by the Central Government on intra-state sales. Rate is half of the total GST rate.
SGST (State GST): Collected by the State Government on intra-state sales. Also half of the total GST rate.
IGST (Integrated GST): Collected by the Central Government on inter-state sales or imports. Equals the full GST rate.

For a Rs 10,000 product at 18% GST sold within the same state: CGST = 9% (Rs 900) + SGST = 9% (Rs 900) = Total Rs 1,800. If sold to another state: IGST = 18% (Rs 1,800).
