Worked Examples

Load these examples to compare common option price scenario payoff outcomes.

SCENARIO PRICE

Price a call after a stock move

A trader wants to estimate option value after a 10% rally.

  • Enter the manual prices and assumptions.
  • Review the calculated risk, reward, and break-even metrics.
  • Compare the chart with the highlighted scenario.

Result: the calculator updates the scenario metrics and chart from those inputs.

Real fills, fees, and broker margin rules are not modeled.

How It Works

This calculator estimates theoretical option value at a target stock price before expiration.

Example Problem

Enter the option type, strike, days, IV, rates, and a scenario stock price.

  1. Price the option at the current stock price.
  2. Reprice it at the scenario stock price.
  3. Compare intrinsic value, time value, and Greeks.

The estimate is model-based and may differ from market quotes.

Key Concepts

Scenario pricing helps separate directional move, time remaining, and implied-volatility assumptions.

Applications

  • Planning exits.
  • Stress-testing calls and puts.
  • Comparing price targets before trading.

Common Mistakes

  • Assuming IV stays fixed.
  • Ignoring bid/ask spreads.
  • Using expiration payoff for a pre-expiration decision.

Frequently Asked Questions

What does the Option Price Scenario Calculator calculate?

It calculates the selected options result from manual inputs, without requiring live stock or option quotes.

Does this calculator need live market data?

Are commissions, taxes, margin interest, and assignment fees included?

No. The result excludes commissions, fees, taxes, borrow costs, slippage, and broker-specific margin rules.

Why can real trading results differ?

Real option prices can change with implied volatility, liquidity, dividends, early assignment, and execution prices.
