Option Strategy Payoff Calculator

Study strategy payoff, breakevens, and sensitivity across price paths. Build flexible legs for engineering cases. Export tables, chart outcomes, and review scenario assumptions easily.

Calculator Inputs

Use preset strategies or build a custom multi-leg structure. The layout stays single-column overall, while form controls use a responsive grid.

Strategy Legs

Formula Used

Long Call Payoff: max(S − K, 0) − Premium

Short Call Payoff: Premium − max(S − K, 0)

Long Put Payoff: max(K − S, 0) − Premium

Short Put Payoff: Premium − max(K − S, 0)

Total Strategy Payoff: Sum of all leg payoffs × quantity × contract size

Here, S is underlying price at expiry, K is strike price, and premium is the per-share option cost or credit. Breakeven occurs where the total strategy payoff equals zero.

How to Use This Calculator

  1. Choose a preset strategy or keep the custom option.
  2. Enter the current underlying price, price range, step size, and contract size.
  3. Define each leg using type, position, strike, premium, and quantity.
  4. Add or remove legs to model spreads, straddles, strangles, or custom structures.
  5. Press the calculate button to view summary metrics, breakevens, chart results, and the data table.
  6. Use the CSV and PDF buttons to export the displayed result set for reporting or engineering decision documentation.

Example Data Table

Example Strategy Leg Type Position Strike Premium Quantity Purpose
Bull Call Spread Call Long 95 8 1 Creates upside exposure.
Bull Call Spread Call Short 110 3 1 Caps upside and offsets cost.
Contract Size 100 Scales per-leg payoff to contract terms.
Range 50 to 150, step 5 Supports payoff curve generation.

This sample shows a common debit spread that engineering analysts can adapt for scenario testing and structured risk comparison.

Frequently Asked Questions

1. What does this calculator measure?

It measures total payoff at expiry for one or more option legs. It combines premiums, strikes, positions, quantities, and contract size into one payoff curve and summary.

2. Does the calculator support multi-leg strategies?

Yes. You can add or remove legs to model custom structures such as spreads, straddles, strangles, butterflies, condors, and other engineered payoff designs.

3. Are the results based on expiry only?

Yes. This tool calculates payoff at expiration. It does not price time value, volatility, or early exercise behavior before expiry.

4. Why is contract size important?

Contract size converts per-share payoff into full contract payoff. For many equity options, 100 is common, but you can change it to match your market or instrument design.

5. How are breakeven points found?

Breakevens are estimated from the plotted range by locating where the total payoff crosses zero. A finer step size produces more detailed breakeven estimates.

6. Can the maximum profit or loss be unlimited?

Yes. Some strategies, especially uncovered short calls or long calls, can have open-ended risk or reward on the upside. The summary detects that case automatically.

7. Why is this useful in engineering work?

Engineering teams often compare nonlinear outcomes under changing inputs. This tool helps structure payoff scenarios, sensitivity ranges, and decision tradeoffs in a clear visual format.

8. What is included in the CSV and PDF exports?

The exports include the displayed price and payoff table. The PDF also includes key summary values so you can document assumptions and results in one compact report.
