</p>What is Options Profit & Payoff?
An options profit calculator maps what a single option position is worth at expiration across a range of underlying prices. It combines the strike, the premium paid or received, and the contract multiplier into a payoff line showing the breakeven point and the maximum gain and loss.
The formula
Long call P/L = (max(0, S − K) − premium) × 100 × contracts- S = underlying price at expiration
- K = strike price
- premium = price paid per share of the contract
- 100 = shares per standard US equity contract
One $50 call bought for $2.00 costs $200, because a standard contract covers 100 shares. At expiration with the stock at $55, the call is worth $5.00 per share, or $500, so the position shows $300. At $52 the call is worth $200 and the position is flat: $52 is the breakeven, the strike plus the premium. Below $50 the call expires worthless and the loss is the full $200.
The four single-leg positions
Every single-option position is a combination of two choices: call or put, bought or sold. Buying pays a premium for a right; selling receives a premium and takes on an obligation. That distinction sets the shape of the payoff and where the risk sits.
| Position | Maximum gain | Maximum loss | Breakeven |
|---|---|---|---|
| Long call | Unlimited | Premium paid | Strike + premium |
| Long put | Strike − premium (floor at $0) | Premium paid | Strike − premium |
| Short call | Premium received | Unlimited | Strike + premium |
| Short put | Premium received | Strike − premium | Strike − premium |
A long put's gain is capped because the underlying cannot fall below zero. A short call's loss is not capped for the same reason in reverse.
In the money is not the same as profitable
A call finishing above its strike is described as in the money, but that is not the same as profitable. The premium has already been paid, so the position only recovers it once the option is worth more than it cost.
For a long call, breakeven is the strike plus the premium; for a long put, the strike minus the premium. An option can therefore expire in the money and still lose money. A $50 call bought for $2.00 that finishes at $51 returns $100 against $200 paid.
Intrinsic and extrinsic value
An option's price splits into intrinsic value, which is what it would be worth if exercised now, and extrinsic value, which is everything else: time remaining and implied volatility.
Intrinsic value for a call is the underlying price minus the strike, floored at zero. Everything above that is extrinsic and decays to nothing by expiration. A calculator that models expiration deals only in intrinsic value, so its payoff line has straight segments and a sharp bend at the strike, while a live option price traces a curve.
Exercise, assignment and the multiplier
Standard US equity options settle into 100 shares each, so every quoted premium is per share and every position size is a multiple of 100 shares of exposure. A $2.00 premium is $200 of cost, and a one-point move in the underlying moves an at-the-money contract by roughly $100 minus the effect of time and volatility.
- American-style equity options can be exercised by the holder at any point before expiration, so a short position can be assigned early, most commonly on a short call before an ex-dividend date.
- Hard-to-borrow costs on the underlying also change when early exercise makes sense for the holder.
- A payoff diagram drawn at expiration shows none of this.
What this calculator does not account for
- StockCram is not affiliated with, endorsed by, or sponsored by any brokerage mentioned on this page. Fee figures are the brokers' own published schedules and change without notice.
- The payoff is drawn at expiration. Before then, time value and implied volatility both affect the price, and a position can be far from its expiration value.
- Commissions are not deducted. Per-contract fees run $0.65 at Schwab, Fidelity and E*TRADE on their published 2026 schedules.
- Early assignment on short positions is not modeled.
- Dividends and hard-to-borrow costs are ignored, both of which affect early exercise on American-style contracts.
- The position is treated as held to expiration rather than closed early.

Frequently Asked Questions
A payoff diagram shows your profit or loss at different stock prices when holding an option. The X-axis shows the stock price at expiration, and the Y-axis shows your profit or loss. It helps you visualize the risk and reward of an options position before entering a trade.
For a call option (long or short), breakeven = strike price + premium. For a put option (long or short), breakeven = strike price - premium. At the breakeven price, your profit is exactly zero (excluding commissions). The calculator shows this as a blue marker on the chart.
When buying a call or put option (long position), your maximum loss is limited to the total premium paid plus any fees. This is one of the risk characteristics of buying options compared to selling them. For example, if you pay $5 per share for 1 contract, your max loss is $500 plus fees.
When selling (writing) a call option, the theoretical maximum loss is unlimited because the stock price can rise without limit. When selling a put option, the maximum loss is the strike price minus the premium received (times 100 per contract), since the stock can only fall to zero. Selling options is generally considered higher risk.
Intrinsic value is what the option would be worth if exercised immediately — for calls, it is the stock price minus the strike price (if positive). Time value is the extra premium above intrinsic value, reflecting the probability of further favorable price movement before expiration. At expiration, only intrinsic value remains.
A short call obligates you to sell shares at the strike price if exercised. Since there is no upper limit on how high a stock can rise, the loss on a short call is theoretically unlimited. This is why short calls are typically part of a covered call strategy (where you already own the shares) rather than sold naked.
Fees and commissions reduce your net profit and increase your effective breakeven point. Most brokers charge a per-contract fee (often $0.50-$0.65 per contract). For small positions, fees can represent a meaningful percentage of the premium. The calculator lets you include fees to see their impact on your P/L.
