Why we built these tools

Most retail losses in index options come from position sizing and cost blindness, not from picking the wrong direction. These calculators remove the guesswork: you can see the net P&L after real Indian trading costs, the exact breakeven, and the position size your capital can actually support.

Each tool is built for Indian market conventions — option premiums, lot-based trading, NSE and BSE index contracts — and works on any device without an account.

How to use them together

  1. Use the position size calculator to decide how many lots your risk budget allows.
  2. Use the premium calculator to sanity-check whether a strike looks cheap or expensive for its implied volatility.
  3. Use the breakeven calculator to know the index level your trade actually needs.
  4. Use the P&L calculator to see what you keep after charges before you enter.

Common questions

Are these tools free?
Yes. All calculators and the market holiday calendar are free and require no account.
Do the calculators use live prices?
No. You enter your own premiums and index levels, which keeps the tools fast and works offline. Use the statistics page for live platform results.
Are the charge estimates exact?
They are close estimates based on standard Indian F&O charges. Brokerage plans, exchange rates and taxes change over time — always confirm against your broker's contract note.
Can I use these for stock options?
The math is the same for index and stock options. Lot size and price inputs are up to you; the defaults use index contracts for convenience.
