  7. Enter exchange + sebi charges — Exchange transaction charges plus SEBI turnover fees, on total turnover.
  8. Enter stamp duty — Charged on the buy side only.
  9. Enter gst — Applied to brokerage and exchange charges.
  10. Read the result — it updates as you type.

The formula used

Total = Brokerage + STT + Exchange fees + Stamp duty + GST

Brokerage
Flat fee per order, or a percentage of each side
STT
Securities Transaction Tax on trade value
Stamp duty
Charged on the buy side only
GST
Applied to brokerage and exchange charges, not to STT

Note that GST is charged on the brokerage and exchange fees, not on the value of the shares and not on STT. That is why the GST amount looks small relative to the trade.

We deliberately do not ship any broker's rate card. Open a recent contract note, copy the rates into the fields above, and this becomes a calculator for your account.

Worked example

Buy 200 shares at ₹500, sell at ₹520, with a ₹20 flat brokerage per order.

  • Buy value₹1,00,000
  • Sell value₹1,04,000
  • Gross profit₹4,000
  1. Brokerage = ₹20 + ₹20 = ₹40
  2. STT at 0.1% both sides = ₹204
  3. Exchange + SEBI at 0.00335% of ₹2,04,000 = ₹6.83
  4. Stamp duty at 0.015% of ₹1,00,000 = ₹15
  5. GST at 18% of (₹40 + ₹6.83) = ₹8.43
  6. Total charges ≈ ₹274, net profit ≈ ₹3,726

The charges took about 6.8% of the gross profit. On a smaller move — say ₹505 instead of ₹520 — they would have taken most of it.

Why charges matter more than most people think

Each individual charge looks trivial. Together, on an active trading account, they are often the difference between a profitable year and a flat one.

Charges are fixed; your profit is not

You pay them on every trade, winning or losing. A strategy that makes 0.5% per trade can be entirely consumed by costs, while the same strategy holding for a 10% move barely notices them.

Delivery and intraday differ

Many discount brokers charge nothing for delivery and a flat fee for intraday. STT is charged on both sides for delivery but only on the sell side for intraday, and at a lower rate. Adjust the STT field to match the trade type you are modelling.

The one number to watch

"Charges as a percentage of turnover" tells you how much a trade must move just to break even. Compare it against the size of the move you are actually expecting.

Tips and common mistakes

Getting more out of it

  • Set STT to the sell side only when modelling an intraday trade — delivery is charged on both sides.
  • Compare the total against your expected profit per trade. If charges are a large fraction of it, the strategy has a cost problem.

Mistakes to avoid

  • Assuming zero-brokerage means zero cost. STT, exchange fees, GST and stamp duty still apply.
  • Using the default rates without checking them — they change, and they vary by broker and segment.
  • Forgetting DP charges, a flat fee per scrip when selling from demat, which this calculator does not include.

Frequently asked questions

Are the default rates correct for my broker?

Treat them as typical starting points only. Statutory rates change and brokerage plans vary widely. Copy the exact figures from a recent contract note.

Why is GST not charged on STT?

STT is itself a tax, so GST is not applied to it. GST applies to services — brokerage and exchange transaction charges.

What are DP charges?

A flat fee your depository participant charges when shares are debited from your demat account on a delivery sell. They are per scrip, not per share, and are not included above.

Do these charges apply to mutual funds?

No. Mutual funds have no brokerage or STT on regular purchases; their cost is the expense ratio, which is already reflected in the NAV.
