Formula and Logic
This tool uses a simplified model for personal finance contexts. Intrinsic value is calculated as the difference between stock price and strike price for calls (or vice versa for puts), but not below zero. Time value is estimated based on the premium and days to expiration, using a linear decay factor. Total cost is premium times shares. Break-even price accounts for the premium paid. Profit/loss is derived from current price versus break-even. ROI is profit divided by total cost.

- Tax implications: Profits from options may be taxed as capital gains; consult a tax advisor.
- Budgeting habits: Use this tool to assess if an option fits your risk tolerance and financial goals.

The intrinsic value will be zero, but the option may still have time value. The tool will show a loss if the break-even price isn't met.
Can I use this for employee stock options?
Yes, but note that employee options often have vesting schedules and tax rules not covered here. Use this as a preliminary estimate.
How accurate is the time value calculation?
This is a simplified model for personal use. For precise pricing, consider professional tools or consult a financial advisor.
