Profit / loss at expiration
📈 Compare options trading platforms
Check it outSingle-leg options, simplified
This models buying one option (a long call or put) held to expiration. Each contract controls 100 shares. A call profits when the stock rises above the strike plus premium; a put profits when it falls below the strike minus premium. The most you can lose is the premium paid. This is educational, not trading advice.
How it’s calculated
Profit = (intrinsic value − premium) × 100 × contracts. Break-even = strike ± premium. Max loss = premium paid.

Common mistakes
- Forgetting each contract controls 100 shares.
- Applying it to spreads or selling, which it does not model.
Frequently asked questions
Does this handle spreads or selling options?
No — it covers buying a single call or put. Multi-leg strategies need a dedicated tool.
What is break-even?
The underlying price where your profit is zero: strike plus premium for calls, strike minus premium for puts.
Why is max loss just the premium?
For a long option, the most you can lose is what you paid — the option simply expires worthless.
