Frequently Asked Questions
Why is the breakeven price important for options?
Breakeven tells you the minimum underlying price movement needed to recover your premium cost. Without knowing breakeven, you may hold an option expecting profit without realizing the stock hasn't moved far enough. It sets realistic profit expectations before entering a trade.
How to calculate breakeven for a straddle?
For a long straddle (buy call + buy put at same strike): Upper Breakeven = Strike + Total Premium | Lower Breakeven = Strike − Total Premium. For example, Nifty 22000 straddle at ₹300 total premium: breakevens at 22300 and 21700. Market must move 300+ points for profit.
What happens at expiry if underlying is at the breakeven price?
At exactly the breakeven price, your option intrinsic value exactly equals the premium paid — you recover your cost but make no profit. This is the "zero profit" point. Above breakeven (for calls) or below breakeven (for puts), you profit. Between strike and breakeven, you lose part of premium.
