Unlimited
Max loss
$915.00
Per share
$7.43

Risk interpretation
This long call has capped premium-at-risk and theoretically unlimited upside at expiry.
Net premium cash flow is -$915.00 after fees. Break-even includes a fee allocation of $0.08 per share.
Position finishes profitable The option finishes in the money at expiry, and the intrinsic value is $2,400.00 before premium and fees are applied.
Planning note
Premium committed or collected before fees is $900.00. Profit at the entered expiry price equals 162.3% of the defined maximum-risk amount.
Payoff scenario table
Compare the entered trade at common underlying-price checkpoints around the current price, strike, break-even, and expiry target.
Options profit calculator guide: call and put payoff, break-even
An options profit calculator translates the basic expiry payoff of a call or put into a full position-level result after contract size and fees are included. This page models long calls, long puts, short calls, and short puts, then shows break-even, maximum profit or loss, return on defined risk where available, and a payoff scenario table around the current price, strike, break-even, and target expiry price.
What this calculator is measuring
This calculator measures the profit or loss of a single-leg options position at expiry. It handles calls and puts, supports both long and short positions, and includes current underlying price so the entered expiry target can be interpreted as a percentage move rather than an isolated future price.
The result is not an estimate of fair value before expiry. It is a direct payoff calculation based on strike price, premium, the underlying price at expiry, contract multiplier, and the fees entered. That distinction matters because options pricing before expiry depends on time value, implied volatility, interest rates, and other variables. At expiry, time value has gone to zero, so the option is worth its intrinsic value only.
Core payoff maths for calls and puts
A call is worth the amount by which the underlying price finishes above the strike price, if any. A put is worth the amount by which the underlying price finishes below the strike price, if any. Long positions pay the premium to obtain that payoff. Short positions collect the premium but take on the obligation created by the option contract.
The calculator starts with intrinsic value per share, then scales that by the number of contracts and shares per contract. Premium and fees are then applied to reach total position profit or loss. Break-even is the underlying price at which the final payoff exactly offsets the premium and fees.
Call intrinsic value = max(Underlying price - Strike price, 0)
Shows what a call is worth at expiry once only intrinsic value remains.
Put intrinsic value = max(Strike price - Underlying price, 0)
Shows what a put is worth at expiry once only intrinsic value remains.
Position profit = Payoff - Premium cash flow - Fees
Converts intrinsic value, premium, and trade costs into the final long or short position result.
Why maximum profit and loss depend on the position side
A long call has limited loss because the most that can be lost is the premium paid plus fees. But its upside is theoretically unlimited if the underlying keeps rising. A short call reverses that payoff: premium collected is the best case, while loss can become very large if the underlying rallies sharply.
Long puts and short puts are different because the underlying cannot fall below zero. That means the maximum payoff of a long put and the maximum loss of a short put are both capped. Understanding that asymmetry is one of the main reasons to review max-gain and max-loss outputs before using any options position for speculation, hedging, or income generation.
How to read break-even and expiry payoff
The break-even point tells you where the trade flips from loss to profit after premium and fees are included. It is not the same as the strike price, and it is not the same as the current market value before expiry. This makes the calculator useful for quickly testing whether the option needs only a small favourable move or a much larger one to work out.
Because the page models expiry payoff only, it is best treated as a single-leg planning tool. If you are comparing alternatives, use the result to compare how premium, position side, strike choice, contract quantity, and fees move the final outcome rather than to estimate live market value.
Using the payoff scenario table
Many competing options payoff calculators use a chart or profit/loss table because a single target price can hide how quickly the payoff changes. This calculator now includes a scenario table around the current underlying price, break-even point, strike price, and entered expiry target so you can see the shape of the trade without needing a separate graphing tool.
For long options, the table makes premium-at-risk easy to see: several low-probability or unfavourable prices may all show the same capped loss. For short options, the table is more important as a warning layer. A short call can keep getting worse as the underlying rises, while a short put has substantial downside if the underlying falls toward zero.
Current price vs expiry price
The current underlying price does not change the expiry payoff formula by itself. A call or put payoff at expiration depends on the final underlying price, strike, premium, contracts, multiplier, and fees. The current price is included because it turns the target expiry price into a move size and anchors the scenario table to realistic checkpoints.
For example, a long call that needs the stock to rise from $100 to $112 is very different from one that needs a move from $100 to $150. The payoff formula may be identical once the final price is chosen, but the planning question is not. Showing the expected move keeps the calculator grounded in the actual setup a trader is considering.
What this options planner does not cover
The calculator does not price time value, implied volatility, Greeks, probability of profit, early assignment probability, margin treatment, exercise style differences, tax treatment, or multi-leg strategy interaction. It is an expiry payoff tool only. If you are trading before expiry, the market value of the option can differ materially from the final payoff shown here.
Use the result as a planning baseline, not as a suitability check. Options are complex products, and short-option positions in particular can expose investors to losses that are much larger than the initial premium collected. For spreads, iron condors, covered calls, or live theoretical pricing, use a more specialized options strategy or Black-Scholes workflow.

Why is break-even different from the strike price?
Because the strike price only determines intrinsic value. The premium paid or collected, plus fees, must also be covered before the full position breaks even.
Why can a short call show unlimited risk?
Because the underlying price can keep rising while the short-call writer remains obligated to deliver at the strike price. There is no built-in upper cap on the underlying price.
Does this calculator show the option's fair value before expiry?
No. It shows the payoff at expiry. Before expiry, market value also depends on time remaining, implied volatility, interest rates, and assignment risk.
Why does contract size matter so much?
Because options are usually quoted per share but traded in standardized contracts. A small-looking premium per share becomes much larger once it is multiplied by the contract size and number of contracts.
Can I use this calculator for spreads or covered calls?
No. It is designed for single-leg positions at expiry. Spreads, covered calls, and other multi-leg structures change the payoff in ways that require a different model.
What changes the break-even price the most?
Premium is the biggest driver because it must be recovered before the trade becomes profitable. Fees and contract count also matter, while the strike price determines where intrinsic value begins.
Why does the calculator ask for current underlying price?
The current price anchors the expected move and the scenario table. The expiry payoff formula itself depends on the final underlying price, but the current price helps you judge whether the entered expiry target is a small move, a large move, or an extreme one.
Does the payoff table replace an options profit graph?
No. It gives a compact profit/loss table at useful checkpoints, which is enough for many single-leg expiry checks. A full graphing tool is still better if you need dense price steps, time decay, implied volatility changes, or multiple legs.
Can this calculator show Greeks or probability of profit?
No. Greeks and probability of profit require an options-pricing model and market assumptions such as volatility, time to expiry, interest rates, and dividends. This page deliberately focuses on transparent expiry payoff math.
