Options Calculators

Free, interactive calculators for the most common options-pricing and risk-analysis tasks. Each tool runs client-side against the same Black-Scholes engine that powers the live platform — no sign-up required.

Black-Scholes Options Calculator — price and 8 Greeks (delta, gamma, theta, vega, rho, vanna, charm) for European calls and puts.
Expected Move Calculator — 1σ implied price range from ATM IV or the ATM straddle.
Options Break-Even Calculator — break-even and max P/L for long calls, long puts, cash-secured puts, and covered calls.
Implied Volatility Calculator — invert the Black-Scholes formula to recover IV from a quoted option price.

For multi-leg strategies and advanced models (Heston, SABR, Local Volatility, Jump-Diffusion), use the full pricing calculator and strategy builder.
