P&L at expiry from intrinsic value vs premium. Each contract = 100 shares. Time value and early assignment aren't modeled — this is the value at expiration.
Profit / loss at expiry
This is one trade's payoff. Whether your options trading is actually profitable over time lives in your trade history.

At expiration, an option is worth only its intrinsic value — the in-the-money amount, if any. Everything you paid above that (time value) has decayed to zero. So your profit comes down to a simple comparison of intrinsic value against the premium:
put intrinsic = max(strike − spot, 0)
long P&L/share = intrinsic − premium
short P&L/share = premium − intrinsic
Example: you buy one $100 call for $2.50 and the stock finishes at $110. Intrinsic value is $10, so you make $10 − $2.50 = $7.50 per share, or +$750 on the contract (×100). Your breakeven was $102.50 (strike + premium), and the most you could have lost was the $250 premium.
How to use this calculator
- Option type & position — call or put, bought (long) or sold (short).
- Strike — the option's strike price.
- Premium — the per-share price you pay or receive.
- Contracts — each controls 100 shares.
- Underlying at expiry — where you expect the stock to settle.
You'll get total P&L, return on premium, breakeven, and your max profit and max loss.
A profitable payoff isn't a profitable strategy.
This shows the math on one trade. Whether your options trading actually makes money over hundreds of trades is a different question — and it lives in your trade history: win rate by setup, average return, the patterns that quietly drain your account. That's what TradeFlow Quantum surfaces: connect your broker, your trades import automatically, and it finds the edge you can't see in a spreadsheet.
