BASIC · EXPIRATION PAYOFF

Long Call Calculator

Explore how a stock price rise affects a purchased call, after the premium you pay.

Your position

Illustrative starting values · USD

Use one stock or ETF and the same expiration for every option leg. Premiums are per share.

Stock quantities are shares. Option quantities are contracts. Enter the total fees for the entire position once.

How to use the long call calculator

Buy a call. Enter its strike, the premium paid per share, and the number of contracts.

Understanding the payoff

Breakeven = strike + premium. Maximum loss is the premium paid. Profit has no upper limit as the stock price rises.

These formulas describe the standard strategy before fees. The results above include the total fees entered and are calculated from your actual legs.

Worked example

A $100 call bought for $5 costs $500 per standard contract. At a stock price of $110 at expiration, the call is worth $1,000 and the profit is $500, before fees.

Assumptions and limits

This is an expiration payoff estimate, not a live option quote or a prediction. It assumes all option legs expire together on one stock or ETF, the stock price cannot be negative, and options settle at intrinsic value. The default multiplier is 100 shares per contract; adjust it for the contract being modeled. Early assignment, exercise decisions, dividends, interest, taxes, and slippage can change realized results. Cash requirements and broker margin are separate from maximum loss. Different expirations, futures options, and adjusted contracts with non-cash deliverables are not supported.

Method: add each leg’s intrinsic value at expiration, subtract its entry cost with the correct buy/sell sign, and subtract total fees. See Cboe’s worked spread example on Fidelity for a reference calculation.
