The Put-Call Parity Calculator is a dedicated tool in our Finance category designed to help you verify put-call parity relationship in seconds. By automating the underlying mathematics, this utility eliminates manual calculations and provides reliable, instantaneous estimations.

Mathematical Principles & Calculation Steps

To compute the results, the calculation engine processes your custom inputs: Call Price ($), Put Price ($), Stock Price ($), Strike Price ($), Risk-Free Rate (%), Time to Expiry (years). Specifically, the calculations are evaluated using the standard relationship: C + K/(1+r)^t = P + S. All computations are performed locally within your secure browser session, ensuring absolute data privacy and instantaneous updates without any network delay.

Worked Step-by-Step Calculation Example

Worked Example Sandbox

For illustrative purposes, consider the following calculation using our default values. When we initialize the input fields with Call Price = 8 $, Put Price = 3 $, Stock Price = 100 $, Strike Price = 105 $, Risk-Free Rate = 5 %, Time to Expiry = 1 years, the client-side calculator processes the numbers to resolve the formula and produce the final outputs: Call + PV(K) = 108 $ and Put + Stock = 103 $ and Difference = 5 $ and Arbitrage (1=Yes) = 1.

How to Use This Calculator

Set Inputs: Adjust the input values: Call Price, Put Price, Stock Price to match your scenario.
Verify Outputs: The outputs: Call + PV(K), Put + Stock, Difference are updated in real-time on your screen.
Iterate: Change values and compare alternative scenarios to find your optimal result.
