How to use this tool
For European options with the same underlying, strike and expiry, call minus put equals dividend-discounted spot minus discounted strike. All values here are per underlying unit.
A residual can reflect stale quotes, bid/ask spreads, financing, discrete dividends or exercise differences. It is not an executable arbitrage recommendation. A negative inferred option price signals inconsistent inputs.
Worked example
At zero rates and dividends with spot $105 and strike $100, a $2 put corresponds to a $7 call.
