The four basic option positions
Long call: pay premium, profit if spot rises above strike + premium. Long put: pay premium, profit if spot falls below strike − premium. Short call: collect premium, lose if spot rises above break-even (theoretically unlimited loss). Short put: collect premium, lose if spot falls below break-even (max loss = strike − premium).
The payoff chart
The calculator plots your profit and loss across a range of spot prices from 50% to 150% of strike. The yellow dashed line marks break-even — above (for calls) or below (for puts) that point you're in the money.
Things this does not model
This is P&L at expiration only. It ignores time decay (theta), volatility changes (vega), and interest rates. For pre-expiry P&L you need a full Black-Scholes calculator with Greeks. For a first-pass “is this trade worth it” check, expiration P&L is what matters.
A payoff at expiry says nothing about what a position is worth before it — that needs time remaining and implied volatility. The Black-Scholes calculator is where those enter.

Frequently asked questions
Common questions about the Options Profit Calculator.
Why does the payoff have a kink in it?
Because an option confers a right rather than an obligation, so beyond the strike the payoff changes slope and on the other side it stops. That asymmetry is the whole point of the instrument, and it is why option outcomes cannot be reasoned about the way a share position can.
Does this account for time decay?
Check the inputs the tool asks for. A payoff at expiry is a different question from a valuation before expiry, where time remaining and implied volatility both matter. A profit figure computed at expiry says nothing about what the position is worth next week.
Why is my broker showing a different profit?
Commissions, the bid-ask spread, exercise or assignment fees, and any financing on a margined position all sit outside a payoff calculation. On small positions those costs can be a large share of the expected profit, which is why the arithmetic and the statement rarely match exactly.
Is this trading advice?
No, it is arithmetic on a position you describe. Options carry substantial risk, some strategies can lose more than the premium paid, and short option positions can lose considerably more than the amount received. Nothing here indicates whether a position is appropriate.
