fin.put-call-parity Calculator
Checks put-call parity arbitrage conditions from call price, put price, spot price, strike, and risk-free rate. Put-call parity violations create riskless arbitrage — in practice, bid-ask spreads and margin requirements eliminate most apparent violations.
Inputs
Call Price
Reference formula or conversion factor shown for context.
Put Price
Reference formula or conversion factor shown for context.
Stock Price
Current price per share. Used in P/E ratios, options pricing, and market cap calculations.
Strike Price
The price at which an option can be exercised. Call options profit when the market price exceeds the strike; put options profit when it falls below.
Rate Pct
Return on a theoretically safe investment like a government T-bill. The baseline return everything else is compared against. Enter as a decimal (e.g. 0.05 for 5%).
Time Years
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
arbitrage opportunity ($/share)
Sample size or count used in the calculation.
