Market facts
Nifty Lot Size
One Nifty 50 futures or options lot is 65 units, the size NSE lists for the contract months from January 2026, down from 75. At an index level of 25,000 (illustrative), one lot has a contract value of ₹16,25,000, and a 100-point move in the index changes the value of one lot by ₹6,500.
Worked example
Contract value = lot size × index level = 65 × 25,000 = ₹16,25,000.
A 100-point change in the index changes the value of one lot by 65 × 100 = ₹6,500, in either direction.
