Worked out in whole paise, the way an invoice must be. GST on the total is ₹1,800.00.
The two formulas
| You have | You want | Formula |
|---|---|---|
| Price before GST | GST amount | Price × rate ÷ 100 |
| Total including GST | Price before GST | Total × 100 ÷ (100 + rate) |
A common mistake
To take 18% GST out of ₹11,800, people often subtract 18% of ₹11,800 and get ₹9,676. That is wrong: the GST was 18% of the price, not of the total. The right price is ₹11,800 ÷ 1.18 = ₹10,000.
Questions
- How do I add GST to a price?
- Multiply the price by the rate. At 18%, a ₹10,000 service has ₹1,800 of GST, so the client pays ₹11,800.
- How do I find the price before GST from a total?
- Divide the total by 1 plus the rate. At 18%, divide by 1.18: a total of ₹11,800 is a price of ₹10,000 and ₹1,800 of GST. Subtracting 18% of the total gives the wrong answer.
- When is it CGST + SGST and when IGST?
- CGST and SGST, half each, when you and your client are in the same state. IGST, the full rate on one line, when the client is in another state.
- Which GST rate applies to freelance services?
- Most professional services, such as design, development, writing, marketing and consulting, are taxed at 18%. Check the rate for your SAC code if you are unsure.
