Calculate purchased call or put expiry profit, payoff and fee-inclusive break-even from supplied prices, contract size and fees. Both supported modes represent a purchased option, not a written or short position. A long call's intrinsic payoff rises above the strike; a long put's rises below it. Premium is a cost in both modes. Reversing the sign to imitate a short option would omit its different risk and obligations, so short-position modeling is intentionally excluded from this option profit calculator.
How to use it
- 1
Prepare the independently established inputs in the units shown, starting with purchased positions.
- 2
Review expiry price and the supported scope before submitting; example defaults demonstrate the arithmetic rather than a personal recommendation.
- 3
Click Calculate result to submit the current values. Input edits retain the previous submitted result until you calculate again.
- 4
Read the labeled output with the worked example, then check return and loss scenarios before using the result in another record.
Formula and methodology
Long call intrinsic=max(0,expiry price−strike); long put intrinsic=max(0,strike−expiry price). Profit=intrinsic×contracts×size−premium×contracts×size−fees. Break-even includes supplied fees per unit.
The calculator applies the displayed arithmetic to the values entered on this device. It does not silently load a local tax rate, currency conversion or commercial assumption.
Worked calculation example
A purchased call with strike 50, premium 3 per unit, one 100-unit contract and total fees 5 costs 305 currency units. At expiry price 60, payoff is 1,000 and profit is 695. Fee-inclusive break-even is 53.05 per underlying unit.
How to interpret your result
A purchased call with strike 50, premium 3 per unit, one 100-unit contract and total fees 5 costs 305 currency units. At expiry price 60, payoff is 1,000 and profit is 695. Fee-inclusive break-even is 53.05 per underlying unit. Purchased vanilla call/put expiry arithmetic only. No live option valuation, volatility, short positions, margin, assignment forecast, taxes or investment recommendation. Compare the labeled intermediate outputs with the input units and convention before carrying a number into another worksheet.

Scenario comparison
| Scenario | What it shows |
|---|---|
| Out-of-money call | expiry price 40 in the example gives zero intrinsic payoff and a loss of 305. |
| Break-even call | expiry price 53.05 makes payoff equal the supplied 305 total cost. |
| Long put | strike 50, expiry price 40, premium three, size one hundred and fees five gives profit 695. |
Common mistakes to avoid
- Entering a total contract premium in the per-unit premium field.
- Applying the long-position formula to a short option.
- Treating expiry intrinsic payoff as a current market valuation.
Return is profit divided by the supplied premium-plus-fee cost, and is undefined when that cost is zero. An out-of-the-money purchased option expires with zero intrinsic payoff and the scenario loses the entered cost. This arithmetic excludes settlement complications and does not recommend a trade. Compare several independently chosen expiry prices to understand the payoff structure without treating any scenario as likely or guaranteed.

Purchased positions
Both supported modes represent a purchased option, not a written or short position. A long call's intrinsic payoff rises above the strike; a long put's rises below it. Premium is a cost in both modes. Reversing the sign to imitate a short option would omit its different risk and obligations, so short-position modeling is intentionally excluded from this option profit calculator.
Expiry price
The supplied underlying price is a scenario at expiration, not a live market quote or a future-price forecast. Before expiry, an option's market value can include time value and reflect volatility and other factors. The intrinsic formula cannot estimate a current resale price. Keep the expiry label when reporting the result so scenario profit is not mistaken for today's mark-to-market valuation.
Premium and contract size
Premium is entered per underlying unit, while whole contracts and units per contract determine the total position size. Contract multipliers vary, so one hundred is only a demonstrative default. A premium of three on a one-hundred-unit contract costs three hundred before fees, not three. Supply the actual documented size, especially for adjusted or nonstandard contracts.
Fees and break-even
Total supplied transaction fees are subtracted once from the full position. Break-even spreads those fees across all underlying units. A call uses strike plus per-unit cost; a put uses strike minus it. If a put's cost exceeds its maximum possible intrinsic value at a nonnegative underlying price, no nonnegative break-even exists. Taxes and unentered charges are not silently estimated.
Return and loss scenarios
Return is profit divided by the supplied premium-plus-fee cost, and is undefined when that cost is zero. An out-of-the-money purchased option expires with zero intrinsic payoff and the scenario loses the entered cost. This arithmetic excludes settlement complications and does not recommend a trade. Compare several independently chosen expiry prices to understand the payoff structure without treating any scenario as likely or guaranteed.
Privacy and browser processing
Values entered on this page are processed in the current browser session. SolvePilot does not require an account and does not receive the values entered into the calculator. Refreshing or closing the page clears the working values unless the browser itself restores a previous session. Avoid entering identifying or account information because the calculation needs summary values only.
Accuracy and verification
Accuracy depends first on input quality. Confirm definitions, scales, dates and source information before entering a value. Keep an independent record of any result used for planning because this page does not create an official statement or retain a calculation history.
Limits of this estimate
Purchased vanilla call/put expiry arithmetic only. No live option valuation, volatility, short positions, margin, assignment forecast, taxes or investment recommendation. The entered values are not independently verified. Numerical output does not establish the suitability of its assumptions for a real situation. Calculator inputs are processed locally in the browser interface; avoid entering identifying records and retain the relevant measurement or source basis with any result you save.

Frequently asked questions
Does this value an option today?＋
No. It calculates intrinsic payoff and profit at a supplied expiry-price scenario.
Are short calls or puts supported?＋
No. Both modes are purchased vanilla options, with premium treated as a cost.
Is contract size always 100?＋
No. One hundred is a default example; supply the documented units per contract.
Are fees included in break-even?＋
Yes. The supplied total fees are allocated across the entered underlying units.
Does the result recommend a trade?＋
No. It is educational payoff arithmetic, not a forecast or investment recommendation.
