When a company offers you equity or stock options as part of a job offer, it can feel like a foreign language — one with real financial stakes. These aren't just perks. Depending on the company's trajectory and how your grant is structured, equity can represent a significant portion of your total compensation. Or it can be worth nothing at all. Understanding the landscape helps you ask the right questions before you sign.
Equity means ownership — a slice of the company. When an employer offers you equity compensation, they're giving you a way to share in the company's financial upside if it grows in value.
Equity isn't cash. It doesn't typically show up in your bank account on payday. Its value — and whether it ever pays off — depends on many factors: the company's stage, its future valuation, market conditions, and the specific terms of your grant.
Equity is most common in startups and tech companies, but it also appears at publicly traded companies and growth-stage businesses across many industries.
Not all equity is the same. The type you're offered matters enormously for how it's taxed, when you can access it, and what it's actually worth.
A stock option gives you the right to buy company shares at a fixed price — called the strike price or exercise price — at some point in the future. You don't own shares yet; you own the option to buy them.
If the company's share price rises above your strike price, your options are "in the money" — you could buy shares at a discount relative to their current value. If the price never rises above your strike price, your options may expire worthless.
There are two main flavors:
| Type | Tax Treatment | Common At |
|---|---|---|
| Incentive Stock Options (ISOs) | Favorable if rules are met; subject to AMT considerations | Private companies, startups |
| Non-Qualified Stock Options (NSOs/NQSOs) | Taxed as ordinary income at exercise | Public and private companies |
Tax treatment is a meaningful difference — one worth discussing with a tax professional before exercising options.
RSUs are a promise to give you actual shares (or their cash equivalent) once certain conditions are met — usually time-based vesting. Unlike options, RSUs don't require you to buy anything. When they vest, you receive shares outright.
RSUs at public companies are generally more straightforward to value because you can look up the stock price. At private companies, RSUs are harder to value because there's no public market for the shares yet.
RSUs are taxed as ordinary income when they vest, based on the share's fair market value at that time.
Some public companies offer ESPPs, which let employees buy company stock at a discount through payroll deductions. This is a separate program from a job offer's equity grant — but worth understanding if it's part of the benefits package.
Receiving an equity grant doesn't mean you own it on day one. Vesting is the schedule by which you earn your equity over time.
The most common structure is a four-year vesting schedule with a one-year cliff:
If you leave before the cliff, you generally walk away with no equity. If you leave after vesting begins, you keep what's vested — but unvested shares stay with the company.
Vesting schedules vary. Some companies offer monthly vesting from day one. Others use performance-based vesting tied to milestones rather than time. Always ask for the full vesting schedule in writing.
When reviewing an equity offer, these are the terms that matter most:
This is where job seekers often get tripped up: equity offers come with numbers that feel concrete but are actually highly uncertain.
At a public company, the math is more transparent. You can look up the stock price, multiply by shares, and get a present-day value — though future value still isn't guaranteed.
At a private company, valuation is an estimate. A startup might be valued at a certain amount today, but that valuation is determined by investors in funding rounds, not by a public market. There's no guaranteed exit. The company may grow, stay flat, get acquired below expectations, or fail entirely.
Factors that shape the potential value of private company equity include:
When an employer presents equity as part of total compensation, you're entitled to ask questions. Most candidates don't — which puts them at a disadvantage.
Reasonable questions include:
That last question matters more than many people realize. The standard post-termination exercise window is 90 days — meaning if you leave, you may need to pay to exercise your options within three months or lose them. Some companies offer extended windows; most don't.
Equity is one piece of a larger picture. When evaluating a job offer, total compensation includes:
The right weight to give equity depends on your financial situation, risk tolerance, career stage, and the specific company's prospects. Someone with significant financial obligations may reasonably prioritize guaranteed cash compensation over uncertain future equity. Someone in a strong financial position may be more comfortable accepting a lower base in exchange for a larger equity stake in a high-potential company.
Neither approach is universally right. Evaluating an equity offer well means understanding what you're actually being offered — and what variables will determine whether it pays off.
Equity compensation involves tax and legal considerations that vary based on individual circumstances. A tax advisor or financial professional familiar with equity compensation can help you evaluate the specifics of your situation.
