WORKING CALCULATOR
Calculate option profit and loss
Start with the example or replace the values with your own scenario. The calculator models the payoff at expiration and shows the result at your target price.

A FIVE-STEP WORKFLOW
How to use the options profit calculator
Turn an option position's terms into an auditable expiration payoff, then compare it with broker or exchange data before deciding.
Enter the trade terms
Enter underlying price, strike, premium per share, contracts, and multiplier. A spread also needs its second strike and premium.
Set a target price
The target is the underlying price used for headline P/L. Change it to test a bullish, bearish, or neutral case.
Calculate profit and loss
Select Calculate Profit & Loss. The result updates target P/L, return on risk, maximums, breakeven, and net debit or credit.
Read the whole payoff
Read the chart and scenario table together; nearby prices may produce a different outcome than one attractive target.
READ THE OUTPUT
What the options profit calculator shows
An option payoff links the underlying price to the position terms. It shows the arithmetic, not a forecast, so compare it with market conditions.
Estimated P/L at target
This is modeled profit or loss at the target price on the selected expiration basis. Positive means the position recovers its modeled cost; negative means it does not.
Breakeven price
Breakeven is where modeled expiration P/L is about zero. A long call usually uses strike plus premium; other strategies use different relationships.
Maximum profit and maximum loss
Defined-risk positions can show a fixed maximum. Long calls have limited loss and uncapped upside; covered calls and spreads have different caps. Use Unlimited or Not capped when no fixed boundary exists.
Net debit or net credit
A debit is paid to open; a credit is received before fees. Premium inputs and strategy direction set this cash flow. Margin and assignment exposure are not estimated.
KNOW THE MODEL BOUNDARY
At expiration vs. before expiration
This first version focuses on expiration payoff, which can be checked from strike, premium, price, quantity, and multiplier. Before-expiration pricing needs more assumptions.
At expiration
The tool applies intrinsic value and adjusts for the entered premium, producing an auditable graph and table without guessing a future quote.
- Uses manual values only
- Clear formula for each strategy
- No live quote or probability claim
Before expiration
Before expiration, time, volatility, rates, dividends, liquidity, and bid-ask spread affect the quote. A model should show its assumptions and timestamp.
- Needs time to expiration
- Needs volatility and rate inputs
- Remains an estimate, not a guarantee
SUPPORTED POSITIONS
Common options strategies in the calculator
Choose the position you are testing. Each formula shows expiration P/L per share before multiplier and contract count.
Long Call
A bullish call purchase pays a premium for upside exposure. Loss is limited to the debit; modeled upside is not capped.
max(S − K, 0) − premium
Long Put
A put purchase benefits below the strike. The premium limits initial risk, while maximum payoff depends on a price floor of zero.
max(K − S, 0) − premium
Covered Call
Stock plus a short call receives premium but gives up upside above the short strike. Purchase price is used as the stock cost basis.
(S − stock cost) + premium − call payoff
Cash-Secured Put
A short put receives premium and may require buying at the strike. The calculator shows downside from strike minus premium.
premium − max(K − S, 0)
Bull Call Spread
A long lower-strike call and short higher-strike call create a debit spread with defined maximum profit and loss.
long call payoff − short call payoff
Bear Put Spread
A long higher-strike put and short lower-strike put create a defined-risk bearish spread. The second leg limits cost and payoff.
long put payoff − short put payoff
ACCURACY AND RISK NOTES
Use the estimate with the right assumptions
An options profit calculator clarifies a position, but incomplete inputs cannot produce a market forecast. Check the assumptions that matter.
Premium and multiplier
Premiums are often quoted per share, while contract value is premium times multiplier. The default is 100; verify the specification for your product.
Fees and execution
The result excludes commissions, exchange and regulatory fees, spread, slippage, borrow cost, taxes, and assignment or exercise costs. Displayed profit is not executable net profit.
Risk is not always capped
Long options and defined-risk spreads have clearer loss boundaries than uncovered shorts. Covered calls still carry stock downside. Read risk, not only target P/L.
Not investment advice
This free options calculator is an educational math tool. It does not recommend trades, predict prices, assess suitability, or guarantee returns. Review the Options Disclosure Document before trading.

COMMON QUESTIONS
Options profit calculator FAQ
These answers explain what the calculator measures, omits, and does not predict.
How do I calculate profit on an option?
Enter the strategy, underlying, strike, premium, contracts, target price, and multiplier. At expiration, the tool applies the payoff formula, adjusts for premium direction, then multiplies per-share P/L by multiplier and contracts.
What is the breakeven price for a call option?
For a standard long call at expiration, breakeven is strike plus premium per share. A $105 strike with a $2.50 premium has a $107.50 breakeven before fees. Multi-leg positions differ.
Can an options profit calculator show maximum loss?
Yes, for strategies with a defined boundary. Long options usually cap loss at the premium, and debit spreads have defined loss. Covered calls carry stock downside; uncovered positions may have no fixed cap.
Is this options calculator accurate before expiration?
This MVP calculates expiration payoff, not before-expiration price. Time value, volatility, rates, dividends, liquidity, and bid-ask spread can change a live quote. Treat model output as an estimate with stated assumptions.
Can I calculate a spread with this tool?
Yes. Choose Bull Call Spread or Bear Put Spread, then enter the second strike and premium. The tool combines both legs and shows net debit, maximums, breakeven, target P/L, and scenarios.
Does the ticker field load live stock prices?
No. Ticker is an optional label; this version does not call a quote API. Verify underlying price, strike, premium, and expiration terms yourself.
What does one options contract represent?
Many standard equity options use a 100-share multiplier, but specifications vary. The default is 100 and can be edited. Confirm multiplier and settlement terms for your contract.
