Options Calculators and Tools
Free educational calculators for position risk, implied moves, and simplified strategy outcomes.
Enter your own hypothetical figures. These tools use simplified expiration assumptions and do not account for every real-world factor.
Position-Size Calculator
Estimate a risk budget and maximum whole contracts based on maximum loss per contract.
Educational estimate only. It does not account for slippage, commissions, gaps, assignment, or losses beyond stated assumptions.
Earnings Implied-Move Calculator
Enter the underlying price and at-the-money call and put premiums for the same expiration.
The long-straddle estimate is a simplified market-implied range, not a probability guarantee or price forecast.
Strategy Outcome Calculator
Calculate simplified expiration outcomes for several common defined-risk or beginner strategies.
Simplified expiration math only. Taxes, commissions, early exercise, assignment, dividends, volatility, and position adjustments are not included.
Before relying on a calculation
Confirm contract specifications, exercise style, settlement method, commissions, dividends, liquidity, early-assignment risk, and broker requirements. Calculator results are educational estimates—not forecasts or trade recommendations.
