Frequently Asked Questions

What is put-call parity?

Put-call parity is the relationship Call Price + Present Value of the Strike = Put Price + Spot Price, for European options with the same strike and expiration on a non-dividend-paying underlying. If it does not hold, an arbitrage opportunity exists.

Does this formula account for dividends?

No, this calculator uses the standard no-dividend form of put-call parity. For dividend-paying underlyings, the present value of expected dividends would also need to be subtracted.
