Formula Used
Call intrinsic value: max(market price - strike price, 0).
Put intrinsic value: max(strike price - market price, 0).
Gross payout: intrinsic value per share x contracts x shares per contract.
Long net profit: gross payout - total premium - fees - slippage.
Short net profit: total premium - gross payout - fees - slippage.
Long call breakeven: strike price + premium + per share costs.
Long put breakeven: strike price - premium - per share costs.
ROI: net profit divided by risk capital or margin, then multiplied by 100.

Understanding Option Payouts
An option payout is the value a contract can produce at expiration. It depends on the option type, strike price, market price, premium, contract size, and trade direction. A call gains value when the market settles above the strike. A put gains value when the market settles below the strike. The payout is not the same as profit. Profit also subtracts premium, fees, slippage, and any other costs.
Why Breakeven Matters
Breakeven gives a trader a clear target. For a long call, breakeven equals strike plus total cost per share. For a long put, it equals strike minus total cost per share. Short positions reverse the cash flow. They start with premium income, but they can lose money when the option moves deep in the money. This calculator shows both gross payout and net result. That split helps users see where money is created or lost.
Advanced Inputs
Contracts can control many shares, so small price changes matter. The contract multiplier converts per share numbers into total trade exposure. Commission, other fees, and slippage are included because they affect real outcomes. A tax estimate can also be applied to positive profit. It is only a planning figure. Actual tax treatment depends on location, holding period, account type, and reporting rules.
Risk Review
Long options have limited loss, usually the premium and costs paid. Their maximum profit depends on option type. A long call has open upside. A long put is capped because a stock cannot fall below zero. Short options need extra care. A short call can have unlimited loss. A short put can lose heavily if the market falls toward zero.
Using The Results
Use the result as a planning model, not as trade advice. Change one input at a time. Test best, normal, and worst cases. Compare several market prices before entering a trade. The example table gives sample scenarios. It can help users learn how premium, payout, and breakeven interact. Always verify contract details with your broker before placing any order. Document each scenario before trading. Save the CSV for review. Export the PDF for records. Revisit assumptions after news, earnings, dividends, or volatility changes. Better records improve future trade discipline and position decisions.
FAQs
What is an option payout?
An option payout is the intrinsic value created at expiration. For calls, it depends on how far price is above strike. For puts, it depends on how far price is below strike.
Is payout the same as profit?
No. Payout is the expiration value before trade costs. Profit includes premium, commissions, fees, slippage, and other adjustments. This calculator separates those values.
How is a call option calculated?
A call uses max(market price minus strike price, zero). That value is multiplied by contracts and shares per contract. Premium and costs are then applied.
How is a put option calculated?
A put uses max(strike price minus market price, zero). The result becomes the intrinsic value per share. Total payout uses the contract multiplier.
What does breakeven mean?
Breakeven is the underlying price where profit is roughly zero after premium and per share costs. Long calls need price above breakeven. Long puts need price below breakeven.
Can this calculator handle short options?
Yes. Select short as the position. The calculator treats premium as income, then subtracts expiration payout, fees, and slippage from the short side.
Why enter risk capital or margin?
Risk capital gives a practical ROI base. It can represent cash paid, margin held, or capital reserved for the trade. Broker requirements may differ.
Is the tax result final?
No. The tax field is only an estimate on positive profit. Real tax outcomes depend on your rules, account, holding period, and reporting method.
