Call & Put Option Calculator

Calculate profit/loss and break-even for long call and long put options.

1 contract = 100 shares
Formulas:
Long Call P/L = (Stock Price − Strike − Premium) × 100 × Contracts
Long Put P/L = (Strike − Stock Price − Premium) × 100 × Contracts
Max Loss = Premium × 100 × Contracts

Understanding Options

A call option gives you the right to buy a stock at the strike price before expiration. A put option gives you the right to sell. You pay a premium for this right.

Key Terms

  • Strike Price: The price at which you can buy (call) or sell (put) the stock
  • Premium: The cost of buying the option contract
  • Break-Even: Strike + Premium (call) or Strike − Premium (put)
  • In the Money: Stock > Strike (call) or Stock < Strike (put)
