RSUs vs Base Salary: What to Optimize For

One of the most consequential financial decisions a software engineer faces is whether to optimize for a higher base salary or a larger RSU grant. The answer depends on your financial situation, risk tolerance, career stage, and the specific company offering the compensation. There is no universal right answer, but there is a framework for making the decision that fits your life.

RSUs (Restricted Stock Units) are shares of company stock granted to you as part of your compensation. They vest over a schedule, typically four years, and you receive the shares (or their cash equivalent) as they vest. Base salary is the fixed cash amount you receive every pay period. Both are taxed as ordinary income, but their behavior over time is very different.

Key Principles

The first principle is that base salary is guaranteed while RSUs are variable. Your base salary will not change with market conditions. RSUs, on the other hand, are tied to the company's stock price. If the stock doubles, your RSUs are worth twice the grant value. If it drops by half, you receive half. This variability is both the risk and the opportunity.

The second principle is that base salary compounds in specific ways. Your future raises, bonuses, and even 401(k) matching are often calculated as percentages of base salary. A higher base creates a higher floor for all future compensation negotiations. When you change jobs, recruiters often ask for your current base as a starting point.

The third principle is that RSUs have asymmetric upside at the right companies. If you join a company whose stock is likely to appreciate significantly, RSUs can dramatically outperform the equivalent value in base salary. Engineers who joined companies like Nvidia, Meta, or Google at the right time saw their RSU grants multiply in value.

The fourth principle is liquidity and timing. Base salary provides immediate liquidity. RSUs require you to wait for vesting dates, and you may want to hold shares beyond vesting for tax optimization or conviction in the stock. If you have near-term financial obligations like a home purchase, base salary is more useful.

Step-by-Step Strategy

Step one: assess your financial foundation. If you do not have an emergency fund, have high-interest debt, or have near-term large expenses, prioritize base salary. Cash flexibility matters more than potential upside when your financial foundation is unstable.

Step two: evaluate the company's stock trajectory. For established FAANG companies, stock prices tend to grow steadily at five to fifteen percent annually. For high-growth companies, the upside can be much larger but so can the downside. Look at the company's revenue growth, market position, and sector trends.

Step three: understand the vesting schedule. Google and Meta use a four-year vest with relatively even distribution. Amazon back-loads vesting with only five percent in year one and fifteen percent in year two, then forty percent in each of years three and four. Amazon compensates with larger signing bonuses in early years, but if you leave before year three, you miss the bulk of your RSUs.

Step four: model the tax implications. Both base salary and RSU vesting are taxed as ordinary income at the federal and state level. However, RSUs create a taxable event at each vesting date based on the stock price at that time. If the stock has appreciated since your grant, you owe taxes on the higher value. If you hold the shares and sell later at a gain, the additional gain is taxed as capital gains (long-term if held more than one year from vesting).

Step five: consider your overall portfolio concentration. If your RSU grants already represent a large portion of your net worth, additional RSUs increase your concentration risk. You are already exposed to your employer through your job. Adding heavy stock exposure doubles down on a single company. In this case, a higher base salary or diversifying your vested RSUs may be prudent.

Step six: factor in refresher grants. Most FAANG companies issue annual RSU refresher grants based on performance. These grants can be substantial, especially at senior and staff levels. A strong initial RSU grant often signals to the company that you value equity, and refreshers tend to track that signal. For details on how refreshers work at senior levels, see our staff engineer compensation guide.

Common Mistakes

The biggest mistake is treating RSUs as cash. Engineers often mentally convert their RSU grant to a dollar value and assume they will receive that exact amount. The stock price at vesting determines the actual value, which can be higher or lower than the grant price.

Another mistake is not selling vested RSUs when portfolio concentration becomes excessive. Many engineers hold one hundred percent of their vested shares out of loyalty or optimism. Financial advisors generally recommend keeping no more than ten to twenty percent of your net worth in a single stock, including your employer.

A third mistake is ignoring the time value of money. A $50K increase in base salary paid over four years has a different value than $50K in RSUs vesting over four years. Base salary is paid continuously, while RSUs vest on a schedule. The base salary provides more value earlier, especially considering investment returns on the incremental cash.

Finally, many engineers fail to negotiate RSU refreshers during annual performance reviews. Refreshers are often more negotiable than base salary adjustments and can significantly increase total compensation year over year.

Real Examples

An engineer choosing between two offers: Company A offers $200K base with $300K RSUs over four years. Company B offers $180K base with $400K RSUs over four years. If both companies' stocks grow at ten percent annually, Company B's total compensation is higher. But if Company B's stock drops twenty percent, Company A's guaranteed cash makes it the better deal. The engineer's risk tolerance and belief in each company's trajectory should drive the decision.

A senior engineer at Google with $250K base and $800K in vested, unreleased RSUs faces significant concentration risk. By selling vested shares quarterly and diversifying into index funds, they reduce company-specific risk while still benefiting from future refresher grants.

Scripts and Templates

When asking a recruiter about RSU details: "Can you walk me through the vesting schedule, the grant price, and how refresher grants are typically handled for this level? I want to understand the full equity picture."

When negotiating for more RSUs instead of base: "I believe strongly in the company's trajectory and would prefer to weight my compensation toward equity. Could we explore increasing the RSU grant by [amount] in lieu of a base salary increase?"

When negotiating for more base instead of RSUs: "Given my current financial situation, I would benefit from a higher base salary. Would it be possible to shift some of the equity value to base compensation?"
