Price and GST
- Price before GST₹8,475 (84.7%)
- GST₹1,525 (15.3%)
Show the calculation steps
- Price before GST = price including GST ÷ (1 + rate) = ₹10,000.00 ÷ 1.18 = ₹8,474.58; GST = ₹10,000.00 − ₹8,474.58 = ₹1,525.42.
- Price including GST = ₹8,474.58 + ₹1,525.42 = ₹10,000.00.
- Within one state, GST splits equally: CGST ₹762.71 + SGST/UTGST ₹762.71.
- GST rates differ by goods and services and are revised by the GST Council. Enter the rate that applies to your item.
Why not just subtract the percentage?
A GST-inclusive price is the base price plus GST on that base price. So the GST is a share of the base, not of the total. That is why the calculation divides by (1 + rate) rather than subtracting the rate from the total.
Where it is useful
Use it for shop prices and MRPs that include GST when you need the taxable value for an invoice, a return or an input tax credit claim.
Formula
GST = Price before GST × GST rate ÷ 100
Price including GST = Price before GST + GST
Price before GST = Price including GST ÷ (1 + GST rate ÷ 100)
Where:
- GST rate
- = The tax rate that applies to the goods or service
- CGST / SGST
- = Central and state halves of GST for supplies within a state
- IGST
- = GST for supplies between states
