Indian markets calculators
Free trading calculators for NSE and BSE index traders — Nifty, Bank Nifty, Sensex, Finnifty — plus helpers useful for MCX-style commodity sizing and currency F&O planning. Estimate option and futures profit and loss, margin lock-ups, brokerage with STT and GST, and breakeven levels before you place an order in your broker app.
Indian F&O is contract-based. Lot size multiplies every rupee of premium or futures point into real P&L. A small premium difference on Bank Nifty becomes a large cash swing once you multiply lots and lot size. That is why dedicated Bank Nifty and Nifty tools sit alongside generic options P&L and margin calculators on this hub.
Charges matter as much as direction. Brokerage may be flat per order on discount plans, but securities transaction tax, exchange transaction charges, SEBI fees, stamp duty and GST still reduce net profit. Run the brokerage calculator on both legs of a round trip before you treat a trade as almost breakeven. Margin calculators help you see capital locked — not the cost of the trade — using a percentage of notional as a planning estimate when live SPAN is not open on your phone.
Lot sizes and charge slabs change over time. Defaults in each calculator are starting points; update lot size and brokerage to match the current contract and your broker plan. Numbers are for education and planning only — confirm with your broker and exchange. For crypto perps, use the crypto calculators instead, or browse the full directory.

Nifty, Bank Nifty and index workflow
A practical workflow for index options: pick the strike and expected exit premium, enter lots and lot size in the P&L calculator, then sanity-check charges. If you are writing or rolling futures, estimate margin on notional next. Greeks tools help you see delta and theta sensitivity when IV or time to expiry changes — still approximations of Black–Scholes-style math, not exchange-grade pricing.
Sensex, Finnifty and other indices follow the same arithmetic with different multipliers. Commodity and currency F&O traders can reuse margin and brokerage helpers by setting the correct contract size and segment. When you want a step-by-step explanation, open the trading calculator guides for Bank Nifty P&L, Nifty margin planning and F&O charge breakdowns.
Wikawe Trading Calculator does not connect to your demat or place orders. It is a planning layer you control. Keep risk capital small while you learn, and never confuse a green net P&L estimate with a guaranteed outcome in live markets.
Intraday index traders should revisit charges on every busy expiry day, when spreads widen and you may trade more lots than usual. Positional traders should revisit margin when VIX rises, because SPAN and exposure requirements can jump even if your futures price has not moved much. Currency and commodity desks can reuse the same margin and brokerage math by swapping contract multipliers and segment settings.
If you are comparing brokers, run the same sample trade through the brokerage calculator under each plan assumption, then decide whether flat fees or percentage fees win for your typical lot count. Pair that with the options P&L tool so you see net rupees after costs, not just premium ticks. All Indian market calculators on Wikawe are free, require no login and are designed to work on mobile between market auctions.
