How This Calculator Works
This calculator models the payoff at expiration. It does not estimate option value before expiration or include implied volatility, interest rates, dividends, commissions, taxes, margin, early exercise, or assignment timing.
Long options
Buyers subtract the premium paid from intrinsic value. The maximum loss is usually the premium paid.
Short options
Sellers start with premium received, then subtract any intrinsic value owed at expiration.
Interesting Fact
Options trading has grown into a very large part of modern market activity. The Options Clearing Corporation reported 15,207,163,554 total options contracts in 2025, a 24.4% increase from 2024. That scale is one reason payoff calculators are useful: even a small premium change can represent a meaningful total dollar move once contracts and multipliers are included.

Options Profit Formula Cheat Sheet
Use these expiration formulas to double-check the calculator and understand why the payoff curve changes shape for each strategy. Net profit is calculated after premium, while intrinsic value is calculated before premium.
Calculate options profit by subtracting total cost from total payoff at expiration. Use this formula: profit = (option value at expiry − premium paid) × contract size (100 shares). For calls, profit rises when price exceeds strike plus premium. For puts, profit rises when price falls below strike minus premium.
| Strategy | Net / Share at Expiration | Breakeven | Max Profit / Max Loss |
|---|---|---|---|
| Long Call | max(expiry - strike, 0) - premium | Strike + premium | Unlimited / premium paid |
| Long Put | max(strike - expiry, 0) - premium | Strike - premium | Limited by zero price / premium paid |
| Short Call | premium - max(expiry - strike, 0) | Strike + premium | Premium received / unlimited |
| Short Put | premium - max(strike - expiry, 0) | Strike - premium | Premium received / limited by zero price |
FINRA explains that calls give buyers the right to buy, puts give buyers the right to sell, and option sellers take on obligations if assigned. Learn more from FINRA's options overview.
Worked Example: Long Call Profit
Suppose you buy 1 call option with a $185 strike, pay a $4.20 premium, and use the standard 100-share multiplier. If the underlying finishes at $195, intrinsic value is $10.00 per share because $195 - $185 = $10.00. After subtracting the $4.20 premium, net profit is $5.80 per share, or $580.00 total for one contract.
Intrinsic Value
$10.00
$195 expiry - $185 strike
Net / Share
$5.80
$10.00 intrinsic - $4.20 premium
Total Profit
$580.00
$5.80 x 100 shares
Before You Trust the Result
This calculator is designed for expiration payoff, so it is strongest when you want a clean profit/loss scenario at a specific final price. Before using the number for a real decision, check these inputs and limitations.
Check the contract multiplier
Many listed equity options use 100 shares per contract, but adjusted contracts can use different deliverables.
Use premium per share
If your broker shows a total debit or credit, divide it by contracts and multiplier before entering it as premium.
Remember assignment risk
Short options can create obligations if assigned, and equity options may be exercised before expiration.
Separate payoff from market value
Before expiration, an option's price can change because of time value, implied volatility, rates, dividends, and liquidity.

Frequently Asked Questions
What does this options profit calculator show?
It estimates profit or loss at expiration for a single-leg call or put option strategy using strike, premium, contract count, multiplier, and the underlying price at expiration. It also turns the same scenario into a payoff graph so you can see how the result changes across different prices.
Why is the option premium entered per share?
Listed equity options are usually quoted per share, even though each standard contract controls 100 shares of the underlying. The calculator multiplies that premium by contracts and the contract multiplier to estimate total debit or credit.
Does this calculate option value before expiration or volatility changes?
No. It is an expiration payoff calculator, so it does not model time value, implied volatility, Greeks, or bid/ask spread changes before expiration. The graph is best used to compare final payoff outcomes, not the live market value of the option before it expires.
What contract multiplier should I use?
For many U.S. listed equity options, one contract represents 100 shares, so the default multiplier is 100. Adjust it for contracts with a different deliverable so the calculator does not overstate or understate the potential gain or loss.
What is the difference between option payoff, reward, and profit?
Payoff usually refers to the option's value at expiration before subtracting the premium. Profit includes the premium paid or received, so it shows the net result of the trade. Reward is a broader way to describe the upside you are targeting, while risk describes how much loss the position could create.
How do I calculate the break-even price for a call or put?
For a call, break-even is strike price plus premium. For a put, break-even is strike price minus premium. The calculator applies the same break-even point for the buyer and seller of the same option type.
Can an option buyer lose more than the premium?
For a simple long call or long put, the maximum loss in this calculator is the premium paid. Other costs, exercise decisions, taxes, and multi-leg strategies such as a spread, straddle, strangle, iron condor, or butterfly are outside this single-leg expiration model.
Why can a short call strategy have unlimited loss?
A short call seller may be obligated to deliver the underlying at the strike price if assigned. Since the underlying price can theoretically keep rising, an uncovered short call strategy can create losses far beyond the premium received.
Does this calculator include commissions, taxes, or margin?
No. The calculator focuses on gross expiration profit or loss for the scenario you enter, before commissions, fees, taxes, margin requirements, and broker-specific assignment or exercise rules.
