Find the stock price at which a call or put option buyer breaks even at expiry.
Call breakeven = Strike price + Premium paid. Put breakeven = Strike price − Premium paid.

An option's breakeven point has a genuinely simple formula: for a call option it's the strike price plus the premium paid, and for a put option it's the strike price minus the premium paid. If a trader buys a $50-strike call for a $3 premium, the underlying needs to reach $53 before the position shows any profit — not $50, because the premium paid has to be recovered first. This is the single most common beginner misunderstanding: confusing the strike price with the actual breakeven price, which is always further out-of-the-money than the strike by exactly the premium amount.
The bigger blind spot is that breakeven-at-expiration and breakeven-right-now are two different numbers. The strike-plus-premium formula tells you where the underlying needs to be at expiration for the position to break even, but an option's price before expiration also includes time value on top of intrinsic value — so a position can show a paper loss even when the underlying is sitting exactly at the calculated breakeven price, simply because time value hasn't fully decayed away yet. Breakeven calculations are also strategy-specific: a simple long call or put has one breakeven point, but multi-leg strategies (spreads, straddles, iron condors) can have two breakeven points or a breakeven range, since multiple premiums and strikes are involved simultaneously.
Breakeven = Strike Price + Premium Paid. For example, a $50 strike call bought for a $3 premium has a breakeven of $53 — the underlying must reach $53 at expiration for the position to show zero profit or loss.
Breakeven = Strike Price − Premium Paid. A $50 strike put bought for a $3 premium has a breakeven of $47 — the underlying must fall to $47 or below for the position to be profitable at expiration.
Because the strike-plus-premium breakeven formula calculates breakeven at expiration specifically. Before expiration, an option's price includes both intrinsic value and time value, so the position can still show a paper loss if meaningful time value remains, even with the underlying sitting exactly at the calculated breakeven level.
Not always — many multi-leg strategies (straddles, strangles, iron condors, spreads) have two breakeven points defining a profitable range, rather than one single number, since they combine multiple premiums and strikes. Each leg's premium and strike needs to be accounted for separately when calculating the full strategy's breakeven range.
