What is the lot size of BANK NIFTY?
One BANK NIFTY lot is 30 units in our Trade Planner (October 2026), so every 1-point move in the index is worth ₹30 per lot.
What one lot costs you in charges
Example: 1 lot of a BANK NIFTY option bought at ₹300 and sold at ₹330 gives 30 points x 30 = ₹900 before costs. With ₹20 brokerage per order the round trip costs:
| Charge | Amount |
|---|---|
| Brokerage | ₹40.00 |
| STT | ₹14.85 |
| Exchange charges | ₹6.62 |
| SEBI fee | ₹0.02 |
| Stamp duty | ₹0.27 |
| GST | ₹8.40 |
| Total | ₹70.15 |
Futures are charged on the full contract value. At an example level of 56,000 one BANK NIFTY futures lot is worth ₹16.80 lakh; a 50-point move is ₹1,500 and the round trip costs about ₹994.14, mostly STT on the sell side.
