Start with credible inputs
Choose the position, strike, premium, contract count and expiration price. Remember that one standard equity option contract usually represents 100 shares.
HOW TO READ THIS
A premium is never
free cash flow.
This tool shows the contract's intrinsic payoff at expiration for one standard 100-share contract. It deliberately does not estimate the option's market value before expiration. Use it to understand the obligation and loss boundary, not to predict what an option should cost today.
OPTIONS PROFIT LOSS CALCULATOR EXPLAINED
What is the profit, loss and break-even price for a call or put at expiration?
An expiration payoff calculator shows how the underlying price changes the profit or loss of buying or selling a call or put after including premium and contract size.
How to interpret the calculator result
Read the result in context
Read break-even, maximum loss, maximum gain and the shape of the payoff together. Short options can create obligations far larger than the premium received.
Turn it into a decision
Use the diagram to understand contractual exposure before considering probability, volatility or position sizing.
COMMON QUESTIONS
Questions about this options profit loss calculator.
Does an options payoff chart include time value?
This chart shows profit or loss at expiration. Before expiration, option value also depends on time, implied volatility, rates and dividends.
Can selling an option lose more than the premium?
Yes. A short put can create a large loss if the share price falls, and an uncovered short call can have theoretically unlimited loss as the price rises.
MODEL & DATA CARD
Inspect the calculation before trusting the result.
What this tool answersCalculates the profit or loss of one standard 100-share option contract at expiration. It is a payoff diagram, not an option-pricing or trade-suitability model.
Calculation method
Call intrinsic value is max(share price − strike, 0); put intrinsic value is max(strike − share price, 0). The premium is added for a seller or deducted for a buyer, then multiplied by 100. Break-even is strike plus call premium or strike minus put premium.
Data lineage
No option chain, volatility surface or quote feed is used. Contract direction, date, premium, current price and strike are user inputs; the expiration date is used only to display calendar days remaining.
Visible checks
The scenario table exposes intrinsic value and net P/L at five prices. At the displayed break-even price, payoff should be zero apart from rounding. Long-option maximum loss equals premium paid; an uncovered short call is labelled as having unlimited loss.
Important omissions
Before expiration, option value also depends on time, implied volatility, rates, dividends, liquidity, exercise style and assignment. Fees, tax, margin requirements and multi-leg interactions are absent. Short-option obligations can exceed the premium received.
