How to Judge a Compensation Package Without Calling Equity Salary

For employee equity in a startup, the sensible starting point is not “How many shares are being offered?” but “What problem is this package meant to solve?” This chapter turns the evidence on cash constraints, retention, promotion, vesting, and firm prospects into a practical judgment sequence. It helps a reader distinguish a package designed to preserve startup liquidity from one designed to retain someone through a milestone or share future ownership, while keeping clear that research estimates are not individualized financial advice or a universal exchange rate between shares and salary.

The question matters because the same percentage can mean very different things. A small ownership stake in a credible, growing firm may be relevant to a worker who can wait for value to materialize. A larger stake in a company with uncertain prospects may not compensate for an immediate cash need. The firm may be trying to conserve cash, align effort, retain a person through vesting, screen for belief in the company, or broaden participation in ownership. Those objectives overlap, but they are not identical, and a grant should be judged against the one that is actually important.

Start with the objective, not the instrument

The Finnish evidence shows why an equity component can appear in a cash-constrained startup's package. Cash wages consume scarce internal funds; equity can conserve liquidity while transferring part of future upside and control. That makes equity a financing margin as well as an incentive. But the fact that a startup has a cash constraint does not tell us that the employee should accept less cash. It tells us that the firm is solving a financing problem by offering a claim whose value and timing differ from a wage.

Begin by naming the desired outcome. If the immediate problem is an employee's need for reliable cash, a contingent claim does not solve that problem merely because its expected value is large. If the problem is keeping a scarce employee through a product or financing milestone, a vesting schedule may be relevant because leaving early can forfeit unvested value. If the objective is internal advancement, equity may strengthen the value of effort, but it cannot substitute for a credible role structure or a real opportunity to move upward. If the objective is ownership participation, then dilution, governance, and the employee's ability to understand and bear the risk become central.

This objective-first approach prevents an easy category error. A firm can use equity to preserve cash and still offer a weak long-term package. It can offer a meaningful ownership claim and still fail to retain people once it vests. It can reduce turnover without producing more promotion. The Finnish study's separate estimates for exit and promotion, and the U.S. evidence on temporary turnover reduction, show why “the equity worked” is too vague to evaluate a package.

The wage comparisons in the Finnish paper give a useful sense of economic scale, but they should be used as benchmarks rather than conversions. The study reports that a 10% increase in equity has a retention effect economically similar to roughly a 14–15% wage increase, while its promotion effect is comparable to a larger wage adjustment, described as roughly 35–40% in the baseline specification. These are comparisons of estimated coefficients within an instrumental-variables model. They show that equity is not necessarily a trivial add-on. They do not imply that one dollar of equity can be substituted for one dollar of salary.

A salary is generally usable when paid.
