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.
| Position | At-expiration P&L per share | Max profit | Max loss |
|---|---|---|---|
| Long call | max(0, S − K) − premium | Unlimited | Premium × 100 |
| Short call | premium − max(0, S − K) | Premium × 100 | Unlimited |
| Long put | max(0, K − S) − premium | (K − premium) × 100 | Premium × 100 |
| Short put | premium − 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.
| Stock at expiry | Intrinsic value | P&L per share | Total P&L (1 contract) |
|---|---|---|---|
| $90 | $0 | $0 − $3 = −$3 | −$300 (max loss) |
| $100 | $0 | −$3 | −$300 (max loss) |
| $103 | $3 | $3 − $3 = $0 | $0 (breakeven) |
| $110 | $10 | $10 − $3 = $7 | +$700 |
| $120 | $20 | $20 − $3 = $17 | +$1,700 |
Worked Example: Short Put
Inputs: short put, strike $95, premium $2.00, 1 contract.
| Stock at expiry | Intrinsic (put) | P&L per share | Total P&L (1 contract) |
|---|---|---|---|
| $80 | $15 | $2 − $15 = −$13 | −$1,300 |
| $93 | $2 | $2 − $2 = $0 | $0 (breakeven) |
| $95 | $0 | $2 − $0 = $2 | +$200 (max profit) |
| $100 | $0 | $2 | +$200 (max profit) |
| $110 | $0 | $2 | +$200 (max profit) |
Worked Example: Long Put
Inputs: long put, strike $95, premium $4.00, 1 contract.
| Stock at expiry | Intrinsic (put) | P&L per share | Total P&L |
|---|---|---|---|
| $100 | $0 | −$4 | −$400 (max loss) |
| $95 | $0 | −$4 | −$400 (max loss) |
| $91 | $4 | $4 − $4 = $0 | $0 (breakeven) |
| $85 | $10 | $10 − $4 = $6 | +$600 |
| $75 | $20 | $20 − $4 = $16 | +$1,600 |
Worked Example: Short Call
Inputs: short call, strike $105, premium $3.00, 1 contract.
| Stock at expiry | Intrinsic (call) | P&L per share | Total P&L |
|---|---|---|---|
| $100 | $0 | $3 − $0 = $3 | +$300 (max profit) |
| $105 | $0 | $3 | +$300 (max profit) |
| $108 | $3 | $3 − $3 = $0 | $0 (breakeven) |
| $115 | $10 | $3 − $10 = −$7 | −$700 |
| $125 | $20 | $3 − $20 = −$17 | −$1,700 |
Expiration vs Before Expiration
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.

- Covered Call — long stock + short OTM call (income overlay)
- Cash-Secured Put — short put + full cash collateral
- Protective Put — long stock + long put (downside hedge)
- Bull Put Spread — short higher-strike put + long lower-strike put
- Bear Call Spread — short lower-strike call + long higher-strike call
- Iron Condor — short OTM put spread + short OTM call spread
- Iron Butterfly — short ATM straddle + long OTM wings
- Calendar Spread — short near-dated + long far-dated, same strike
- Wheel Strategy — CSP to assignment to covered call cycle
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.
