F&O margin calculator
Build a position leg by leg and see what it costs to carry — SPAN, exposure and the expiry-day add-on, computed from the exchange's own daily risk parameter file.
Paste an existing position instead
Paste rows from your broker, or use the explicit format one per line: NIFTY, CE, 2026-09-01, 24200, SELL, 2. Quantities are read in units and converted with the registry’s lot size.

What this is, and what it is not
This calculator states the exchange margin — SPAN plus exposure — for the position you describe, computed from the NSE Clearing daily risk parameter file. It is a calculation, not investment advice and not a recommendation to take any position. Nothing here is personalised to your circumstances.
Your broker's number will differ. Brokers add their own margin on top of the exchange requirement, apply their own haircuts to pledged collateral, and may impose ad-hoc margins. Your own terminal governs what you can actually place.
The figure is as of a business date. The risk parameter file is published per trading day, so intraday moves are not reflected until the next file. The basis actually used is shown above every result. Derivatives carry a risk of loss that can exceed the margin deposited.
