Options Profit and Loss Calculator
Work out the profit or loss of a single-leg option at expiration. Enter a long or short call or put with its strike, premium and number of contracts to see the breakeven price, maximum profit, maximum loss and a payoff table across a range of underlying prices.
How to use the options profit calculator
- Pick call or put, then long (bought) or short (sold).
- Enter the strike price, the premium per share and the number of contracts.
- Read the breakeven, max profit and max loss, plus the payoff table by price.
Examples
Long call, strike 100, premium 5
Buy 1 call, strike 100, premium 5, 100 shares per contract
Breakeven 105, max loss -500, profit unbounded; P/L at 120 is +1,500
Long put, strike 100, premium 5
Buy 1 put, strike 100, premium 5
Breakeven 95; P/L at 80 is +1,500, max loss -500
Frequently asked questions
How is the option profit calculated?
At expiration each share is worth its intrinsic value: max(price - strike, 0) for a call, max(strike - price, 0) for a put. Profit per share is that value minus the premium for a long position (negated for a short), and the total multiplies by contracts times the contract size (usually 100).
How do you find the breakeven price?
For a call the breakeven is the strike plus the premium, since the option must rise enough to recover what you paid. For a put it is the strike minus the premium. Short positions break even at the same prices as the matching long.
What are the maximum profit and loss?
A long call has a capped loss equal to the premium paid and unbounded upside. A long put caps the loss at the premium and caps the gain at (strike - premium) since the price cannot fall below zero. Short positions flip this: a short call has unbounded loss, and both shorts cap the gain at the premium received.
Does this handle American options or multi-leg strategies?
No. It models a single leg held to expiration, so it ignores early exercise, time value before expiry and combined strategies like spreads, straddles or iron condors. The figures are the payoff at the expiration date only.
Is this financial advice?
No. Options are high risk and can lose their entire value, and selling options can expose you to large or unlimited losses. This tool is for education and illustration only, not a recommendation to trade. Consider speaking with a licensed professional before trading options.
Do you store my inputs?
No. The calculation runs entirely in your browser. Your strike, premium, contracts and other figures are never sent to a server or saved.
