📐 How GST is Calculated
Forward Calculation (Net → Gross):
GST Amount = (Original Price × GST Rate) / 100
Gross Price = Original Price + GST Amount
Reverse Calculation (Gross → Net):
GST Amount = (Gross Price × GST Rate) / (100 + GST Rate)
Net Price = Gross Price – GST Amount
CGST / SGST / IGST:
For intra‑state sales: CGST = SGST = GST Amount / 2
For inter‑state sales / imports: IGST = GST Amount (full)
Example: Product price ₹1000, GST 18%. GST = ₹180, total = ₹1180. CGST = ₹90, SGST = ₹90.
❓ Frequently Asked Questions
What is GST? +
GST (Goods and Services Tax) is a comprehensive, multi‑stage, destination‑based tax levied on every value addition. In India, it replaced many indirect taxes like VAT, service tax, excise duty, and more.
What are the different GST slabs? +
India has five GST slabs: 0.25%, 3%, 5%, 12%, 18%, and 28%. Essential items attract lower rates, while luxury goods attract higher rates.
How to calculate GST backwards? +
If you know the total price including GST, use reverse formula: GST amount = (Total × Rate) / (100 + Rate). Then subtract from total to get the original price.
What is the difference between CGST, SGST, and IGST? +
CGST (Central GST) and SGST (State GST) are for intra‑state sales – revenue split between centre and state. IGST (Integrated GST) is for inter‑state sales and imports – revenue goes to centre initially, then apportioned.
