How do I calculate options profit?

For a long call: Profit = (Stock Price - Strike Price - Premium) x 100. For a long put: Profit = (Strike Price - Stock Price - Premium) x 100. Each contract is 100 shares. Max loss when buying is the premium paid.

What is the breakeven price?

For a call: Breakeven = Strike + Premium. For a put: Breakeven = Strike - Premium. The stock must pass breakeven for you to profit at expiration.

What is max loss on a long option?

When buying a call or put, max loss is the premium paid. A $3 premium costs $300 per contract (100 shares x $3).

What does 'contracts' mean?

Each option contract controls 100 shares. Premiums are quoted per share, so multiply by 100 for the actual cost per contract.
