GST Calculation Formula

Formula to Add GST:

GST Amount = Original Price × GST Rate / 100
Total Price = Original Price + GST Amount

Example: ₹10,000 + 18% GST
GST = 10,000 × 18/100 = ₹1,800
Total = ₹10,000 + ₹1,800 = ₹11,800

Formula to Remove GST from MRP:

Original Price = MRP / (1 + GST Rate/100)
GST Amount = MRP – Original Price

Example: MRP ₹11,800 includes 18% GST
Original = 11,800 / (1 + 18/100) = 11,800 / 1.18 = ₹10,000
GST Amount = 11,800 – 10,000 = ₹1,800
