Understanding GST in India
GST (Goods and Services Tax) is a unified indirect tax applied to goods and services. It replaces multiple older taxes like VAT, excise duty, and service tax. There are four primary GST slabs:
5%: Essential items (e.g., groceries, footwear).
12%: Processed foods, computers.
18%: Most common slab (e.g., electronics, cosmetics).
28%: Luxury items (e.g., cars, premium appliances).
How to Calculate GST: Forward vs. Reverse
1. Forward Calculation (GST on Base Price)
Use this to add GST to the original amount.
Formula:
CGST = (Base Price × GST Rate) / 2
SGST = (Base Price × GST Rate) / 2
IGST = Base Price × GST Rate (for inter-state sales)
Total Price = Base Price + CGST + SGST (or IGST)
Example:
Base Price = ₹1,000 | GST Rate = 18%
CGST = ₹90, SGST = ₹90, Total = ₹1,180
2. Reverse Calculation (Extract GST from Total Price)
Use this to find the GST amount hidden in the total price.
Formula:
Base Price = Total Price / (1 + GST Rate/100)
GST Amount = Total Price – Base Price
Example:
Total Price = ₹1,240 | GST Rate = 12%
Base Price = ₹1,240 / 1.12 = ₹1,107.14
GST Amount = ₹1,240 – ₹1,107.14 = ₹132.86
