How to Use the Long Call Calculator
This calculator computes the net profit or loss from buying a call option at expiration. It uses a standard contract multiplier of 100 shares per contract.
- Enter Stock Price at Expiration ($): The market price of the underlying stock when the option expires.
- Enter Strike Price ($): The price at which you can buy the stock via the option.
- Enter Premium Paid ($ per share): The cost of one option share (not per contract).
- Enter Number of Contracts: How many option contracts you bought (each contract = 100 shares).
- Click Calculate.
Results:
- Intrinsic Value: The in-the-money amount per share (stock price minus strike, or $0 if negative).
- Payoff per Share: Intrinsic value minus premium paid.
- Total P/L: Payoff per share × 100 shares × number of contracts. Positive = profit (green), negative = loss (yellow), zero = breakeven.
All inputs must be non-negative numbers. Contracts must be at least 1.

Frequently Asked Questions
A long call option gives the buyer the right, but not the obligation, to buy a stock at a specified strike price before expiration. The buyer pays a premium for this right.
Profit = (Stock Price at Expiration - Strike Price - Premium Paid) * 100 * Number of Contracts, but only if the stock price is above the strike price. Otherwise, the loss is limited to the premium paid.
The break-even point is Strike Price + Premium Paid. At this stock price, the option has no net profit or loss.
