Calculation Method
Long put P/L = (max(K − S, 0) − premium) × 100 × contracts.
Break-even: call = strike + premium; put = strike − premium. Max loss = premium paid; call upside is unlimited, put max profit = (strike − premium) × 100 × contracts.

Frequently Asked Questions
What does this calculator cover?
Profit and loss at expiration for a long (bought) call or put, including break-even and the full payoff graph.
What is break-even for an option?
For a long call it is strike + premium; for a long put it is strike − premium. The underlying must pass break-even for the trade to profit at expiration.
Why is each contract ×100?
Standard US equity options control 100 shares per contract, so dollar P/L scales by 100 × contracts.
Does this include time value or Greeks?
No. It shows value at expiration (intrinsic only). Before expiration, options also carry time value and volatility effects.
Is options trading risky?
Yes. Long options can lose 100% of the premium. This tool is educational and not trading advice.
