Why this distinction matters
Equity compensation like stock options and restricted stock units, commonly called RSUs, can make up a meaningful part of a total offer, especially at technology or growth-stage companies. Understanding the difference helps you evaluate what you are actually being offered.
Both are ways to receive company shares as compensation, but they work quite differently in terms of cost, risk, and timing. Confusing the two can lead to unrealistic expectations about what your equity is actually worth.
How stock options work
A stock option gives you the right to buy company shares at a fixed price, called the strike price, at some point in the future. If the company's share price rises above that strike price, you can potentially profit by buying low and selling at the higher market price.
If the share price stays below the strike price, however, the options can be worth little or nothing, since there is no benefit to buying shares at a price higher than the market rate. This makes options inherently more speculative than some other forms of equity.
- You typically must pay the strike price to exercise the option.
- Value depends entirely on the share price rising above the strike price.
- Options often come with a vesting schedule before they can be exercised.
- There may be tax implications when you exercise or later sell shares.
- Unexercised options can expire worthless if the price never rises enough.
How RSUs work
Restricted stock units represent a promise to give you actual shares once certain conditions, usually a vesting schedule, are met. Unlike options, you do not pay a strike price. Once vested, the shares are yours, and they generally have real value as long as the company's stock has any value at all.
Because there is no purchase price involved, RSUs are often seen as less risky than options, since they hold some value even if the share price has not grown dramatically. This makes them a more predictable component of compensation in many cases.
Comparing risk and potential upside
Stock options carry more risk but also more potential upside, since a low strike price combined with significant share price growth can produce outsized returns relative to the cost. This tends to appeal to those willing to accept more uncertainty for potentially higher rewards.
RSUs offer more predictable value with less dramatic upside, since you are simply receiving shares rather than betting on price appreciation above a strike price. For many employees, this predictability is genuinely valuable, especially at more established companies.
- Options: higher potential upside, but real risk of ending up worthless.
- RSUs: more predictable value, generally lower dramatic upside.
- Vesting schedules apply to both, delaying when you can access value.
- Company stage and stability affect which structure makes more sense.
- Your personal risk tolerance should factor into how you value each offer.
Tax treatment differences
Tax rules for options and RSUs differ and can be genuinely complex, often depending on the type of option and when you exercise or sell. It is worth reviewing your specific situation with a tax professional rather than relying on general assumptions.
In broad terms, RSUs are often taxed as income when they vest, while options may involve tax considerations both when exercised and later when sold, depending on the option type. These differences can meaningfully affect the real value of an offer.
Evaluating equity as part of an offer
When comparing job offers that include equity, ask specific questions: how many shares or options, the vesting schedule, the strike price for options, and the company's current valuation or share price if available. This lets you estimate a realistic range of value.
Equity is inherently less certain than cash salary, so it is reasonable to weigh it as a bonus on top of a fair base salary, rather than a guaranteed substitute for competitive cash pay. A thoughtful comparison protects you from overvaluing speculative components of an offer.
Summary
Equity compensation can be confusing when comparing job offers. Learn the practical differences between stock options and RSUs and how each affects your real earning potential.

- Vesting schedules apply to both and affect when you can access value.
- Tax treatment differs between options and RSUs and can be complex.
- Ask for specific details before valuing equity as part of a job offer.
