Hidden Stock Broker Charges Explained — What You're Actually Paying

"Zero brokerage" doesn't mean a trade is free. Here's the full list of charges that apply regardless of which broker you use.

Brokerage Is Just One Line Item

"Zero brokerage" marketing refers specifically to the broker's own execution fee — it doesn't mean a trade has no cost at all. Several other charges apply on every trade, set by the government and exchanges, not by your broker, and they apply no matter which broker you use.

The Full List of Charges on a Typical Trade

• Brokerage — your broker's own fee, the only one that varies meaningfully by broker choice
• Securities Transaction Tax (STT) — a direct government tax on every executed trade, with rates that differ by segment (delivery, intraday, futures, options) and have been revised periodically — for example, futures and options STT rates changed as recently as April 1, 2026
• Exchange Transaction Charges — a fee charged by NSE/BSE for using their trading infrastructure
• SEBI Turnover Fees — a small regulatory fee
• GST — applied on brokerage plus exchange charges combined (not on STT or stamp duty)
• Stamp Duty — a state government charge on the transaction
• DP (Depository Participant) Charges — a per-transaction fee applied specifically when you sell shares from your demat holdings (delivery sells), charged by the depository (NSDL/CDSL) via your broker, separate from brokerage

Why This Matters More Than People Realize

On a single small trade, these combined charges might amount to a few rupees and go unnoticed. Over hundreds of trades a year, particularly for active traders, they add up to a genuinely meaningful amount — sourced comparison data shows total charges (not just brokerage) making a real difference to net returns, which is exactly why comparison tools now calculate "net P&L" including all these charges rather than just brokerage alone.

A Worked Example, Illustrating the Point

Consider a delivery trade: buying shares worth ₹2,80,000 and later selling at a modest 0.5% gain (₹1,400 profit before charges). After accounting for STT, exchange charges, GST, and DP charges on the sell side — even before any brokerage — a meaningful portion of that gross profit can be consumed by statutory charges alone. This is precisely why comparing "net take-home" across brokers, not just headline brokerage rates, gives a more honest picture.

What Varies by Broker vs. What Doesn't

The Bottom Line

When comparing brokers, look at total estimated cost per trade (using a brokerage calculator that includes all these charges, not just the headline brokerage rate) rather than comparing brokerage percentages alone — the statutory charges are identical everywhere, so the real broker-driven difference is smaller than the headline brokerage number alone might suggest, especially for delivery-based investing.
