What is the SENSEX lot size?
One SENSEX lot is 20 units in our Trade Planner (October 2026), so every 1-point move in the index is worth ₹20 per lot.
What one lot costs you in charges
Example: 1 lot of a SENSEX option bought at ₹200 and sold at ₹240 gives 40 points x 20 = ₹800 before costs. With ₹20 brokerage per order the round trip costs:
| Charge | Amount |
|---|---|
| Brokerage | ₹40.00 |
| STT | ₹7.20 |
| Exchange charges | ₹3.08 |
| SEBI fee | ₹0.01 |
| Stamp duty | ₹0.12 |
| GST | ₹7.76 |
| Total | ₹58.17 |
Futures are charged on the full contract value. At an example level of 82,000 one SENSEX futures lot is worth ₹16.40 lakh; a 60-point move is ₹1,200 and the round trip costs about ₹971.45, mostly STT on the sell side.
Your loss at a 60-point stop, by number of lots
Options bought at ₹200 and sold 60 points lower:
| Lots | Units | Loss before charges | Loss with charges |
|---|---|---|---|
| 1 | 20 | ₹1,200 | ₹1,254 |
| 2 | 40 | ₹2,400 | ₹2,461 |
| 3 | 60 | ₹3,600 | ₹3,669 |
| 5 | 100 | ₹6,000 | ₹6,083 |
Lot size is set by BSE and is revised from time to time (often January and July). Check the BSE contract specifications before you trade; you can type a different lot size into the planner.
