Option Payoff Formulas & Trader Guide

🟢 Call Option (CE) Payoff

Buy Call (Long CE): Profit = Max(0, Spot Price - Strike Price) - Premium Paid.

Breakeven = Strike Price + Premium Paid. Risk is limited to premium; profit is unlimited.

🔴 Put Option (PE) Payoff

Buy Put (Long PE): Profit = Max(0, Strike Price - Spot Price) - Premium Paid.

Breakeven = Strike Price - Premium Paid. Risk is limited to premium; profit occurs when market falls.

💡 Pro Hack: Avoid Hero-Zero Buying

Far Out-of-the-Money (OTM) options lose 100% of their extrinsic time value (Theta) on expiry day. Trade In-the-Money (ITM) or At-the-Money (ATM) options for higher delta and probability of profit.

⚡ Importance of Breakeven

Always calculate your breakeven price before entering a trade. If Nifty is at 24,000 and you buy a 24,200 Call for ₹100, Nifty must rise past 24,300 (+1.25%) just for you to break even at expiry.

🛡️ IV Crush Alert

Prior to major news (Union Budget, RBI Policy, Corporate Earnings), Implied Volatility (IV) spikes, inflating premiums. Post-event IV crush collapses premiums even if price moves in your direction.

⚠️ Critical Option Trading Pitfalls

  • • Naked Option Selling Without Stop Loss: Selling uncovered calls or puts carries unlimited loss potential during sharp market gaps. Always define stop-loss levels or hedge with spreads.
  • • Ignoring Transaction Costs & STT: STT (Securities Transaction Tax) is charged @ 0.125% on exercised in-the-money options at expiry, which can eat into small option profits.
  • • Over-Leveraging Lot Sizes: Buying 20–50 lots just because premium is low (₹5–₹10) exposes you to 100% capital destruction on rapid time decay.

Frequently Asked Questions

What is the breakeven price for a Call Option?
For a Long Call Option, Breakeven Price = Strike Price + Premium Paid. For example, if you buy a Nifty 24,000 Call at a ₹100 premium, your breakeven price at expiry is ₹24,100.
What is the breakeven price for a Put Option?
For a Long Put Option, Breakeven Price = Strike Price - Premium Paid. If you buy a Nifty 24,000 Put at ₹100 premium, your breakeven price at expiry is ₹23,900.
What is the maximum loss in buying a Call or Put option?
When buying options (Long Call or Long Put), your maximum loss is strictly capped at the total premium paid (Premium × Lot Size × Number of Lots).
What is the maximum profit in Option Selling (Writing)?
When selling options (Short Call or Short Put), your maximum profit is limited to the total premium received. However, maximum loss is theoretically unlimited.
What is the current Nifty 50 lot size?
NSE Nifty 50 derivative lot size is 25 shares per lot (revised by NSE). BankNifty lot size is 15 shares, and FinNifty lot size is 25 shares.
Does option payoff change before expiry?
Yes. Before expiry, option prices are impacted by Implied Volatility (IV) and Time Decay (Theta). At expiry, the payoff depends purely on intrinsic value (Spot Price vs Strike Price).
What is Intrinsic Value vs Extrinsic Value?
Intrinsic Value is the actual in-the-money amount (e.g. Spot ₹24,100 - Strike ₹24,000 = ₹100 intrinsic). Extrinsic Value (Time Value) is the remaining premium amount above intrinsic value.
Are STT and brokerage included in option payoff?
Standard option payoff diagrams show gross P&L. To calculate net P&L, subtract STT (0.125% on exercised options or 0.0625% on premium), exchange transaction charges, and broker fees.
