I receive many questions from my students and other startup joiners regarding how to evaluate the value of the stock options they are being offered. There is surprisingly little written about this topic, so this post will hopefully be useful to folks interested in answering this question.

In order to properly assess the value of your stock options, you need to know four pieces of information from the company:

1. The number of shares they are offering to grant you
2. The total number of fully diluted shares of the company
3. The common stock strike price of your shares
4. The preferred post-money valuation of the last round of financing

Many HR departments don’t know the answer to these four simple questions and get very defensive when asked by candidates, perhaps out of embarrassment or a false sense of confidentiality. Don’t be afraid to escalate the conversation to a more senior hiring manager or financial executive to get the answer. After all, it’s impossible to understand the value of the options package unless you have the data you need to evaluate it.

From these four data points, you should perform the following calculation using your best judgment:  what might be the dilution that I will face in the coming years as a result of future financings and what might be the range of valuation increases that the company might be able to achieve.

With this information in mind, you can derive a range of possible values of your stock options and evaluate whether the scenarios make sense to you and what range of value is possible under the different scenarios. The spreadsheet template below provides an example that you can play with or download here:

Hopefully, this template and post are helpful! I welcome any feedback or stories you might want to share on your own stock options negotiation process.
