The formula
Adding GST: GST = amount × rate ÷ 100; total = amount + GST.
Removing GST from an inclusive amount: taxable value = amount × 100 ÷ (100 + rate); GST = amount − taxable value.
Within a state, GST is split equally into CGST and SGST. Between states, it is charged as IGST.
Worked example
A GST-inclusive price of ₹1,180 at 18%: taxable value = ₹1,180 × 100 ÷ 118 = ₹1,000, and GST = ₹180, split as CGST ₹90 + SGST ₹90 for a sale within your state.
Questions about this calculator
Why not just take 18% off the inclusive price?
Because the 18% was added to the taxable value, not the total. Taking 18% off ₹1,180 gives ₹967.60, which is wrong; dividing by 1.18 gives the correct ₹1,000.
Which GST rate applies to my products?
It depends on the goods or services and can change. Check the current rate with your accountant or the official GST sources before you set prices.
