Future Value of Stock Options

A stock option value calculator finds the intrinsic value of your options, the gain you'd realize by exercising and selling at the current share price.

Intrinsic value, defined

Intrinsic value is shares times the difference between the current price and your strike (exercise) price, floored at zero. If the stock trades above your strike, each option is 'in the money' by that gap; if it trades below, the options are 'underwater' and worth nothing to exercise right now.

What this leaves out

This is a snapshot of exercise value today. It ignores time value (the chance the stock rises further before options expire), taxes, which can be significant and differ for ISOs versus NSOs, vesting schedules, and the cost to exercise. Treat the number as the current paper gain, not the after-tax cash you'd pocket, and consult a tax advisor before exercising.

How to use it

  1. Enter the number of options.
  2. Enter the strike (exercise) price.
  3. Enter the current share price.
  4. See the intrinsic value and gain per share.

Frequently asked questions

How do I value my stock options?

Intrinsic value = number of options × (current price − strike price), never below zero. Enter your figures above.

What does 'underwater' mean for options?

The share price is below your strike price, so exercising would cost more than the shares are worth, the options have no intrinsic value now.

Does this include taxes?

No. Exercising options can trigger significant taxes that differ by option type. Consult a tax advisor before acting.
