Stock options vs. RSU: what’s the difference?

1 min readLast updated December 5, 2023by Rachel Carey

From basic explanations to similarities and differences and questions around vesting and negotiating, we look at stock options vs. RSU from all angles.


  • Restricted stock units don’t involve stock or transaction pricing. 

  • With RSUs, companies promise employees stock once specific requirements are fulfilled. 

  • Stock options give you the option of buying equity in the company at a specified price during a specified period. 

  • RSUs and stock options have similarities, such as grant dates and differences, such as exercise price. 

What is an RSU? 

Properly known as restricted stock units, RSU became fashionable in the 90s and early 2000s. Less complicated than stock options, RSUs don’t involve transaction or stock pricing. Instead, the company promises to give stock in the company to an employee when the employee fulfills a specific requirement, such as length of service or meeting performance requirements. 

If you meet the requirements, the company will give you RSUs as shares or as the cash equivalent of the stock’s value at that time. Most RSUs vest for a period of time during which the employee cannot access or otherwise benefit from them.  

RSUs can be a good choice if you prefer a more predictable income stream and don’t want to risk a declining stock price. The steadier equity compensation stream they offer isn’t dependent on the stock price at the time of sale or exercise. 

What are stock options? 

With a stock option, you can purchase equity in a company at a specified price within a specified period of time. You are under no obligation to purchase the shares. 

In most cases, one stock option contract represents 100 shares in the company. Stock options usually have a vesting schedule that requires you to work at the company for a certain length of time before you can purchase the stock. Some stock options have an expiration date, after which you cannot exercise your right to purchase stock. 

Stock options may be a good choice if the company is a startup or at an early stage of its growth, isn’t profitable yet, and has strong growth potential. You could make significant gains if the company’s stock price rises over time.

Can I negotiate for more stock options or RSUs when joining a new job or during compensation discussions? 

Yes, you can often negotiate for more stock options or RSUs as part of your compensation package, depending on your position and the company's policies. 

Are stock options and RSUs a common form of compensation in companies? 

Yes, both stock options and RSUs are commonly used by many companies as part of employee compensation packages. Ensure you understand what an RSU is and what stock options are so that you can make an informed decision if you are offered a choice between the two. 

Can I trade or sell my RSUs, or do I need to wait until they fully vest? 

You usually need to wait until RSUs vest before you can trade or sell them, but the specific rules may vary depending on your company's policies. To vest fully means that the RSUs have reached the end of the specified vesting period. 

During the vesting period, you cannot access, sell, or trade your RSUs. However, once the vesting period is over, you acquire full ownership of those stock units and can sell or trade them as you please. 

What happens to my stock options or RSUs if I leave my job before they fully vest? 

Unvested stock options typically expire upon leaving the job. This means that you will not be able to buy stock in the company after you leave their employment.  

Unvested RSUs may have forfeiture or clawback provisions depending on the company's policies. If a clawback provision is involved, you will need to surrender any gains from restricted stock vesting to the company. One of these provisions could also see you surrender bonuses or incentive compensation you received within a certain period. 

What factors should I consider when choosing between stock options and RSUs as part of my compensation package? 

Consider factors such as your financial goals, risk tolerance, and your view on the company's growth prospects when deciding which equity-based incentive suits you better. It is also helpful to speak to a financial advisor about choosing RSUs vs stock options.
