📐 How to Calculate GST
GST Amount = Original Price × GST Rate / 100
GST-Inclusive Price = Original Price × (1 + GST Rate/100)
Example: A product costs ₹1,000 before GST. At 18% GST: GST amount = ₹180, final price = ₹1,180.
To find original price from GST-inclusive amount: Original Price = GST-Inclusive Price / (1 + GST Rate/100)
