Stock Option Value Calculator

About this calculator

The intrinsic value of a vested stock option is the difference between the current market price of the stock and the option's strike price (the price you are entitled to buy it at), multiplied by the number of options — if the current price is below the strike, the option is worth nothing to exercise today and has zero intrinsic value.

This is a simplified view: it only captures value from vested options that could be exercised right now, and it ignores time value — the extra value an unexpired option carries from the chance the stock price rises further before expiration, which is what more complex models like Black-Scholes are built to estimate. For a quick read on what already-vested options are worth if exercised today, though, intrinsic value from strike and current price is the number employees check most often.
