How the options profit calculator works
Options profit isn't linear, and the premium you pay changes everything. This calculator models a long call or long put at expiration: it finds your breakeven, caps your maximum loss at the premium paid, and shows your profit or loss at whatever underlying price you enter — so you know the trade's shape before you place it.
- One contract controls 100 shares, so P&L and premium are always multiplied by 100 × the number of contracts.
- A long call profits above the strike + premium (its breakeven); a long put profits below strike − premium.
- The most you can lose on a long option is the premium you paid — no more — which this tool shows as your max loss.

Options Profit Calculator — FAQ
What is the breakeven on an option?
For a long call it's the strike plus the premium you paid; for a long put it's the strike minus the premium. Below (call) or above (put) that price at expiration, the trade is a net loss even if the option finishes in the money.
What is my maximum loss on a long option?
Exactly the premium you paid, times 100 times the number of contracts — nothing more. That capped, known risk is a big part of why buying options appeals to traders who want defined downside.
Does this include time decay before expiration?
This models profit and loss at expiration, where an option is worth only its intrinsic value. Before expiration, time value and implied volatility also affect price — factors a full options platform or your journal's option analytics will track for you.
