What is an options breakeven price?
An options breakeven calculator estimates the underlying share price at expiration where a long option's intrinsic value equals its cost. For a long call, breakeven is strike price plus premium per share and per-share fees. For a long put, it is strike price minus premium per share and per-share fees. This calculator also converts total fees across the entered contracts and multiplier into a per-share amount.
For example, one call with a $100 strike and a $5 premium per share has a $105 expiration breakeven before fees. Above that price, the option's intrinsic value exceeds the premium paid; below it, the call expires with no intrinsic value. One put with the same strike and premium has a $95 breakeven before fees. These are arithmetic examples, not prices for a particular listed contract.
The calculation assumes a long call or long put held through expiration and a single share multiplier for all contracts. It reports breakeven per underlying share, the position's total premium and fees, and the underlying price at which modeled net expiration payoff is zero. Some options have adjusted deliverables after corporate actions; their multiplier and deliverable may not be the standard share count, so use the contract's actual terms.
Before expiration, an option can have time value and implied volatility effects. Its market price can therefore differ from intrinsic value, and the underlying need not reach this expiration breakeven for the option to be sold at a gain or loss earlier. Exercise, assignment, settlement, and transaction rules vary by contract and broker. The tool does not estimate option value before expiration, probabilities, margin, taxes, early exercise, dividends, or changing fees.
For a long option, the premium and fees are costs paid. The maximum modeled loss is limited to those costs if the option expires worthless, though this does not account for other account-level effects. A long call's theoretical upside increases as the underlying rises. A long put's payoff is bounded by the underlying reaching zero. These payoff descriptions assume the contract is held at expiration and do not describe a recommendation or likely outcome.
Frequently asked questions
Does breakeven include fees?
Yes. Enter total fees and commissions for the position; the calculator spreads that amount across the underlying shares represented by all contracts.
Does this work for selling options?
No. It models buying calls or puts. Short option positions have different payoff shapes, obligations, and risk, and are outside this calculator.
Is the result useful before expiration?
It is an expiration payoff threshold only. Before expiration, time value, volatility, and other pricing factors affect an option's market value.
Should I assume every contract represents 100 shares?
No. The multiplier is an input. Verify the deliverable and contract specifications with the listing venue or broker, especially for adjusted contracts.
