How options profit and loss work
Buying an option (call or put) gives you the right — but not the obligation — to buy or sell the underlying asset at the strike price on or before expiry. Your maximum loss as a buyer is the premium paid. Your profit is theoretically unlimited for calls and substantial for puts.
Selling (writing) an option is the mirror image: you collect the premium upfront, but face significant loss if the underlying moves against you. Most experienced traders either sell options with defined risk (credit spreads) or hedge their short positions.
Key terms affecting profit calculation
- Strike price: The agreed price at which you can buy (call) or sell (put) the underlying.
- Premium: The price paid for the option contract. On NSE, one Nifty options lot is 75 units — verify current lot size before calculating P&L.
- Breakeven for calls: Strike + Premium. For puts: Strike – Premium. The underlying must cross this level by expiry for the buyer to profit.
- Theta (time decay): Options lose value as expiry approaches. Buyers fight theta; sellers earn it.
Indian equity index options (Nifty, Bank Nifty, Sensex) are European-style (exercisable only at expiry) and settle in cash. Stock options are American-style and can result in physical delivery if exercised in-the-money.
Frequently asked questions
What is the maximum loss on buying a call option?â–¼
The maximum loss for a call option buyer is exactly the premium paid multiplied by the lot size. If you buy a Nifty call at ₹120 premium with a lot size of 75, your maximum loss is ₹120 × 75 = ₹9,000 per lot. This occurs if Nifty closes below the strike at expiry, making your call worthless. Unlike futures, there are no margin calls for option buyers.
How are options gains taxed in India?â–¼
F&O trading (including options) is treated as business income in India, not capital gains. Profits are taxed at your applicable income tax slab rate. F&O losses can be carried forward for 8 years to offset future F&O profits. Turnover for tax audit purposes is calculated as the sum of absolute values of all F&O profits and losses.
What does 'in the money' and 'out of the money' mean?â–¼
For call options: In-the-money (ITM) = underlying price above strike (has intrinsic value). Out-of-the-money (OTM) = underlying price below strike (zero intrinsic value). For put options, it's reversed: ITM = underlying below strike. OTM options have lower premiums but need a larger move to become profitable — making them higher-risk, higher-reward bets.
What is the difference between options and futures P&L?â–¼
Futures P&L is linear: a 100-point Nifty move creates the same profit/loss regardless of where Nifty is. Options P&L is non-linear due to delta, gamma, theta, and vega. An OTM call option may barely move when Nifty rises 50 points but accelerates as it approaches and passes the strike. This non-linearity is why options are powerful for risk management but complex to model without an options pricing formula (Black-Scholes).
