Options Profit Calculator — P&L at Expiration

This options profit calculator computes the at-expiration profit or loss for a long call, short call, long put, or short put; enter your strike, premium, and number of contracts and it returns max profit, max loss, breakeven, and a P&L table across any price range. All calculations are intrinsic value only — this tool does not model time value or Greeks before expiration.

How This Calculator Works

At expiration, an option's value is purely its intrinsic value — the difference between the underlying price and the strike, or zero if that difference is negative. This calculator applies the four single-leg payoff formulas exactly.

PositionAt-expiration P&L per shareMax profitMax loss
Long callmax(0, S − K) − premiumUnlimitedPremium × 100
Short callpremium − max(0, S − K)Premium × 100Unlimited
Long putmax(0, K − S) − premium(K − premium) × 100Premium × 100
Short putpremium − max(0, K − S)Premium × 100(K − premium) × 100

S = underlying price at expiration; K = strike price. The total position P&L multiplies the per-share figure by 100 times the number of contracts.

Worked Example: Long Call

Inputs: long call, strike $100, premium $3.00, 1 contract.

Breakeven = K + premium = $100 + $3.00 = $103.00
Max loss = $3.00 × 100 = $300 (call expires worthless at or below $100)
Max profit = unlimited (rises $100 per $1 the stock moves above $103)

Worked Example: Short Put

Inputs: short put, strike $95, premium $2.00, 1 contract.

Breakeven = K − premium = $95 − $2.00 = $93.00
Max profit = $2.00 × 100 = $200 (put expires worthless at or above $95)
Max loss = ($95 − $2.00) × 100 = $9,300 (underlying to zero)

Worked Example: Long Put

Inputs: long put, strike $95, premium $4.00, 1 contract.

Breakeven = K − premium = $95 − $4.00 = $91.00
Max loss = $4.00 × 100 = $400 (put expires worthless at or above $95)
Max profit = ($95 − $4.00) × 100 = $9,100 (underlying to zero)

Worked Example: Short Call

Inputs: short call, strike $105, premium $3.00, 1 contract.

Breakeven = K + premium = $105 + $3.00 = $108.00
Max profit = $3.00 × 100 = $300 (call expires worthless at or below $105)

Expiration vs Before Expiration

This calculator models at-expiration intrinsic P&L only. Before expiration, an option's market value includes time value (extrinsic value) on top of intrinsic value. If you close a position before expiration, your actual P&L will depend on how much time value remains, the current implied volatility, and any dividends — none of which this calculator models. Use this tool to understand the expiration-day payoff structure; use a live broker platform or options pricing model for pre-expiration mark-to-market values.

The at-expiration model is still useful for planning because it sets the profit and loss boundaries of any position. Knowing the max loss before entering a trade is a prerequisite for sizing a position correctly. Knowing the breakeven tells you how far the stock must move — in dollar terms — before the position is profitable at expiration.

Frequently Asked Questions

What does this options profit calculator compute?
It computes the at-expiration profit or loss for a single-leg option position — long call, short call, long put, or short put. Enter the strike price, premium per share, and number of contracts. The calculator returns max profit, max loss, breakeven price, and a P&L table across a price range you set.
Does this calculator account for time value or implied volatility?
No. This calculator computes intrinsic P&L at expiration only, based on where the underlying closes relative to the strike. It does not model theta decay, delta, gamma, vega, or any other Greek. P&L at any point before expiration will differ from the figures shown here because the option still has time value remaining.
How is the breakeven price calculated?
For a long call or short call: breakeven = strike + premium. For a long put or short put: breakeven = strike minus premium. These are the at-expiration prices at which the position has exactly zero profit or loss, before commissions.
What is the maximum loss on a long call?
For a long call, the maximum loss is the total premium paid: premium per share times 100 times the number of contracts. This occurs when the underlying closes at or below the strike price at expiration and the call expires worthless.
What is the maximum loss on a short put?
For a short put, the maximum loss is (strike minus premium) times 100 times contracts. This is realized if the underlying falls to zero. Example: short put strike $95, premium $2, 1 contract — max loss = ($95 minus $2) times 100 = $9,300.
