What is a brokerage Calculator?
The brokerage your broker charges is usually the smallest line item on a contract note. Securities Transaction Tax (STT), stamp duty, exchange transaction charges, SEBI fees and GST on top of brokerage all add up — and delivery and intraday trades are taxed differently, which catches people out when they compare a trade’s "profit" to what actually lands in their account.
Enter your buy price, sell price, quantity and segment to see every charge broken out and your true net P&L.
What’s included
STT is charged on both legs for delivery trades but only on the sell leg for intraday. Stamp duty applies only on the buy side. GST at 18% applies on brokerage plus exchange transaction charges plus SEBI charges — not on STT or stamp duty, which are taxes, not services.
Worked example: the same trade, delivery vs. intraday
Buy 100 shares at ₹500, sell at ₹520, with a ₹20 flat brokerage per order. As a delivery trade, gross profit is ₹2,000, STT alone is roughly ₹102, and total charges (brokerage + STT + stamp duty + exchange + SEBI + GST) come to roughly ₹160 — leaving a net profit of roughly ₹1,840. The identical trade squared off intraday sees STT drop to roughly ₹13 (charged only on the sell leg, at a much lower rate) and total charges fall to roughly ₹65, leaving a net profit of roughly ₹1,935.
The gross profit is identical in both cases — the entire ₹95 difference in net outcome comes purely from the lower regulatory charges applicable to intraday trades, not from anything about the trade itself.
Why charges matter more on frequent, smaller trades
On a ₹2,000 gross profit, roughly ₹160 in charges is a manageable 8% drag. On a smaller trade — say a ₹200 gross profit on a similarly-sized position — the same rough ₹160 in charges could consume the entire gain. Charges are largely fixed (brokerage) or percentage-of-turnover (STT, stamp duty, exchange fees), not scaled to your actual profit, which is exactly why frequent small trades are far more sensitive to the cost structure shown here than occasional larger ones.
Frequently asked questions
Why is STT different for delivery vs intraday?
Delivery trades attract STT of 0.1% on both the buy and sell value, since ownership actually transfers. Intraday trades — squared off same day, no real delivery — attract a lower 0.025% STT charged only on the sell side.
What brokerage should I enter?
Most discount brokers charge a flat fee per executed order (commonly around ₹20, sometimes ₹0 for delivery) rather than a percentage — check your broker’s tariff sheet and enter their per-order flat fee.
Are these charges the same for F&O trades?
No — futures and options have their own STT rates and a different charge structure (including a distinct stamp duty rate). This calculator is built for equity delivery and intraday trades specifically.
Why is GST charged on brokerage but not on STT?
STT and stamp duty are themselves taxes levied by the government, and GST doesn’t apply to other taxes. Brokerage, exchange transaction charges and SEBI charges are fees for a service, which is why 18% GST applies specifically to those three.
Do exchange charges differ between NSE and BSE?
They can, though both are typically very small (a fraction of a percent of turnover) and broadly similar in magnitude — this calculator uses a standard approximate rate; check your contract note for the exact figure your broker’s exchange routing applied.
Does this calculator account for DP (Depository Participant) charges?
No — DP charges are a separate, typically flat fee charged by your depository participant when you sell shares from your demat holding (not on every trade), and vary by broker. They’re not included in this calculation.
Why might my actual contract note show slightly different numbers?
Small rounding differences, a broker-specific brokerage structure (some charge the lower of a flat fee or a percentage), or minor exchange rate variations between NSE and BSE can all cause your real contract note to differ slightly from this estimate.
