How do equity grants actually work?

An equity grant is a promise: the company gives you the right to own company stock, spread out over years. But the way that promise is structured—what type of equity, when it vests, at what price, with what conditions—determines whether you actually become wealthy or walk away with nothing. Most people misunderstand how equity works in practice, treating a $200,000 grant as instant $200,000 wealth when in reality it's a 4-year, conditional, illiquid, and tax-complicated bet on the company's future.

Quick definition: An equity grant is an award of company stock (RSUs) or the right to buy stock (options) that vests over time. Until vesting, you own nothing. After vesting, you either own shares (RSU) or can buy them (option) at a predetermined price.

Key takeaways​

  • Equity grants vest over time, usually 4 years. You don't own the shares on day one. They drip to you over months and years, with most structures including a "cliff" where you own nothing until month 12, then suddenly own 25%.
  • Grant-date value is not the same as your actual wealth. A $200,000 grant is the stock price times the number of shares on grant day. That number can increase, decrease, or become zero depending on stock price movement and company performance.
  • RSUs (restricted stock units) and stock options are different animals. RSUs make you a shareholder automatically at vest. Options give you the right to buy shares at a fixed price; if the stock price drops, your options may expire worthless.
  • Vesting cliffs are wealth traps. If you leave before the cliff (typically month 12), you forfeit your entire grant. If you leave one month after the cliff, you've finally earned something—but you're still missing 75% of your equity.
  • Vesting acceleration clauses protect you in layoffs or hostile takeovers. Without one, a merger can destroy 75% of your unvested equity overnight. With acceleration, your shares vest immediately.

What is a grant, and what does "value" mean?​

An equity grant is a document that says: "We're awarding you X shares (RSU) or Y options with a strike price of Z." The company assigns a "grant-date fair value" to the grant—typically the stock price on the day the grant is issued.

If the company grants you 1,000 RSU when the stock price is $100, the grant-date fair value is $100,000. But here's what this number actually means: it's the value today, not the value you'll realize when you sell.

Grant-date fair value is an accounting fiction. It matters for taxes (you owe tax on vest-date value, not grant-date value), but it doesn't determine how much money you make. A stock that's worth $100 on grant day might be worth $50 or $200 on vest day. You can't spend "fair value"—you can only spend the money when you sell the shares at the actual market price.

How RSUs (Restricted Stock Units) work​

An RSU is a restricted share. On grant, you own nothing. At vest, you own an actual share. Most companies grant RSUs rather than actual shares because RSUs are simpler to administer and have better tax treatment for the company.

The 4-year vest with 1-year cliff:

A typical schedule for 1,000 RSU:

  • Months 1–12 (year 1): 0% vests. You own 0 shares. If you leave, you get nothing.
  • Month 12 (end of year 1): 25% vests. You own 250 shares.
  • Months 13–24 (year 2): Another 25% vests gradually (about 2% per month). By month 24, you own 500 shares.
  • Months 25–36 (year 3): Another 25% vests. By month 36, you own 750 shares.
  • Months 37–48 (year 4): Final 25% vests. By month 48, you own all 1,000 shares.

The 1-year cliff is the key trap: leave at month 11 and you get $0. Leave at month 13 and you suddenly own 250 shares, worth maybe $25,000. The cliff is intentional—companies use it to force retention. If you're confident you'll stay 4 years, the cliff is fine. If you're unsure or the company feels unstable, a 6-month cliff or quarterly vesting from day one is better.

Pro-rata vesting on involuntary termination:

Most companies include a clause: if they lay you off (not for cause), you vest a percentage of your remaining equity. For example, "upon involuntary termination, vest immediately the number of shares that would have vested had you remained for 3 additional months." This soften the blow but doesn't fully protect you. If you were laid off at month 18 with 750 shares unveiled, this clause might give you an extra 50 shares (25% of the quarterly vest), bringing you to 800 instead of 750. It's a cushion, not a cure.

When RSUs become actual shares:

On the vest date (e.g., month 12), the company either delivers shares directly to your brokerage account or to an equity plan administrator. You now own the shares and can sell them immediately (if it's a public company) or hold them (if you're betting on further price appreciation). When you sell, you owe capital gains tax on the difference between the vest-date value (what you owed income tax on) and the sale-date value.

How stock options work​

Options are different: they give you the right to buy company stock at a fixed price (the "strike price"), not the stock itself.

Grant: 10,000 options with a $50 strike price.

This means: "You have the right to buy 10,000 shares at $50 each, regardless of what the stock price is." If the stock price rises to $100, you can exercise your option (buy 10,000 shares for $500,000) and immediately sell them for $1,000,000, netting $500,000 profit. If the stock price drops to $40, your option is worthless—you'd never exercise it because you can buy the same shares on the market for $40, not $50.

Options vest the same way as RSUs. A 4-year vest with a 1-year cliff is standard. You earn the right to exercise them over time, not all on day one.

How options are taxed:

  • At grant: No tax. You don't own anything yet.
  • At vest: No tax (for non-qualified options, or ISO, depending on type). You can now exercise, but you don't have to.
  • At exercise: You buy shares at the strike price. Depending on the option type (NSO vs ISO), you may owe tax now or later.
  • At sale: You owe capital gains tax on the difference between your exercise price and the sale price. If you exercised at $50 and sold at $100, you owe capital gains on the $50 gain per share.

The strike price is frozen at grant. If you were granted options at $50 and the stock rises to $200, your options are still $50. This is why early employees at pre-IPO startups can become extraordinarily wealthy—they were granted options when the company was worth $1M, and 5 years later it went public at $10B valuation.

Vesting schedule variations​

Not all vesting schedules are 4 years with a 1-year cliff. Here are common variations:

Monthly vesting from day one: 1/48th of your shares vest each month. No cliff. If you leave at month 24, you own 50%. This is rarer but better for you because there's no "all-or-nothing" month 12 moment.

Quarterly vesting: 1/16th vests each quarter. Some companies do this instead of monthly to reduce administrative overhead.

2-year vest: Common in early-stage startups. Two years of tenure = 100% ownership. Often with a 6-month cliff instead of 1-year. This is actually better for you because you reach full vesting faster.

Vesting acceleration on change of control: If the company is acquired, merges, or goes through a hostile takeover, your unvested shares vest immediately. This is essential; without it, a merger can wipe out 75% of your equity. Top negotiators always push for "double-trigger acceleration": equity vests if (1) the company is acquired AND (2) you lose your job as a result.

Vesting acceleration on death or disability: Most companies automatically vest all remaining equity if you die or become disabled. Standard and protective.

Grant timing and new-hire grants​

When you join, when do your shares start vesting?

Your equity grant usually has a "grant date"—the official day the award begins. Often this is your first day of employment, but companies sometimes grant equity at a different date (e.g., end of month for administrative simplicity). This date matters because:

  1. It sets your strike price (for options).
  2. It sets the grant-date fair value (for tax withholding).
  3. It determines when the cliff hits (12 months from grant date).

If a company tells you "your grant starts vesting January 1" but you don't start until January 15, your cliff is December 31 of the following year—meaning your first month of employment doesn't count toward vesting. Negotiate for grant date = start date if possible.

Refresh grants and long-tenure employees:

Equity grants are typically back-loaded—you get the most when you're hired, then smaller refreshes later. Some companies grant new equity every year; others grant every 2 years. A refresh grant usually has the same 4-year vest as your initial grant.

Example: hired in 2020 with 1,000 RSU vest over 4 years. In 2021 (when you've earned 25% of your initial grant), you might receive a 500 RSU refresh grant, also vesting over 4 years. This keeps higher-performing employees engaged with equity upside as they progress.

Real-world examples​

Example 1: Tech employee, public company (Google)

  • Grant: 200 RSU at $130/share = $26,000 grant-date value
  • Vesting: 4 years, 1-year cliff
  • Month 12: 50 shares vest at current price, say $140 = $7,000. You owe $7,000 in income tax (assumed 50% bracket = ~$3,500 out of pocket).
  • Month 24: Another 50 shares vest at, say, $155 = $7,750. You owe income tax.
  • Month 36: Another 50 shares vest at $160 = $8,000.
  • Month 48: Final 50 shares vest at $165 = $8,250.
  • Total realized: $7,000 + $7,750 + $8,000 + $8,250 = $31,000 (before capital gains if you held and sold later)
  • Notice: you made $5,000 more than the grant-date value because the stock price rose. Your tax bill was based on vest-date values, not grant-date value.

Example 2: Startup, private company (Series B round)

  • Grant: 50,000 options, strike price $0.50/share = $25,000 grant-date value (theoretical)
  • Vesting: 4 years, 1-year cliff, pro-rata on involuntary termination
  • After 2 years: 25,000 shares are vested. Company is valued at $100M (next funding round).
  • After 4 years: Company raises Series D at $500M valuation. All 50,000 options are vested and worth $499.50 each (stock price implied by valuation: roughly $500M / 10M shares outstanding ≈ $50/share, minus your $0.50 strike = $49.50 per share). 50,000 × $49.50 = $2,475,000 profit.
  • Tax on exercise: likely $0 if you hold long enough and these are ISO (Incentive Stock Options).
  • This is the startup wealth story: you join at $0.50/share and the company grows 100x. You're now a millionaire.

Example 3: Startup, layoff at month 15

  • Grant: 40,000 options, strike price $1/share
  • Vesting: 4 years, 1-year cliff
  • After 15 months: 10,000 shares are vested (1-year cliff = 25%). Company is acquired for $50/share.
  • You exercise your 10,000 options for $1/share ($10,000) and immediately sell for $50/share ($500,000). Gain: $490,000.
  • But you lose 30,000 unvested shares because the acquisition doesn't trigger acceleration and your severance package doesn't include continuation. You made $490,000 instead of $2 million.

This is why acceleration clauses and severance negotiation matter so much.

Decision tree: evaluating an equity grant​

Common mistakes​

Not understanding the cliff is a trap. You're hired in January with a 1-year cliff. You quit or get fired in October—11 months later. You own zero. Your colleague was hired 2 months earlier and left at the 13-month mark—they own 25% of their grant. The 2-month timing difference cost you thousands. Always know your cliff date.

Not negotiating acceleration clauses. A startup is acquired but your role is eliminated. Your grant was 50,000 shares, 25,000 are vested, and acceleration is not in your contract. You're laid off 2 days later with no severance acceleration. You lose 25,000 shares—potentially hundreds of thousands of dollars. Acceleration clauses should be in every offer letter.

Confusing strike price with grant-date value. A company grants you 10,000 options with a $5 strike when the stock is at $5. Someone says "that's a $50,000 grant." But strike price isn't value—it's the price you pay to exercise. The grant value is $0 until the stock price rises above $5. If the stock drops to $3 and stays there, your options expire worthless.

Not withholding taxes on RSU vests. When 100 RSU vest and you owe $20,000 in income tax, the company usually withholds shares to cover it. But if you don't have cash available, you might end up with a tax bill you can't pay. On large vests, set aside cash in advance or negotiate a cash-withhold option.

Staying at a company just to "vest my equity." You're unhappy at a startup that granted you 100,000 options, but you've only vested 25,000. You stay another year to hit 50,000. But the company's performance is declining and the stock value (if it ever IPOs) is going to be lower. You'd be better off leaving and finding a better role at a company with upside. Don't let unvested equity be a golden handcuff if the company isn't going anywhere.

FAQ​

Why do companies use vesting cliffs instead of immediate full ownership?​

Companies use cliffs to reduce turnover. If you own all your shares on day one, you could leave after a week. With a cliff, you have an incentive to stay past year 1. It's a retention tool. It's also psychologically powerful—after 12 months of work, that first chunk of equity vesting feels like a win.

Can I negotiate a shorter cliff or no cliff?​

Yes, especially at startups or smaller companies. Large public companies usually have fixed vesting schedules. But it's always worth asking: "Would you consider a 6-month cliff instead of 1-year?" Many companies will say yes. At smaller companies, you might negotiate monthly vesting from day one.

What happens to my equity if the company goes public?​

If the company is private and you have vested shares or options, you can't sell them. But once the company IPOs, your shares are liquid and you can sell at any time. Options must be exercised (you pay the strike price) before you can sell. Post-IPO, there's usually a lockup period (90–180 days) where insiders can't sell, but after that, you're free.

What's the difference between ISO and NSO options?​

ISOs (Incentive Stock Options) have better tax treatment: if you hold for 2 years from grant and 1 year from exercise, gains are taxed as long-term capital gains (~15% federal rate for most earners). NSOs (Non-Qualified Options) are taxed as ordinary income at exercise, then as capital gains on any appreciation after. ISOs are usually reserved for employees; NSOs are for contractors. Always clarify which type you're getting.

What if the company is acquired before I fully vest?​

If the acquisition includes an acceleration clause (usually double-trigger: acquisition + job loss), you vest all remaining equity. Without it, you typically lose all unvested equity unless the acquiring company agrees to honor it. This is a dealbreaker negotiation point—push hard for double-trigger acceleration in your offer.

How should I think about private-company equity value?​

Apply a risk discount of 30–50%. If the company claims your equity is worth $200,000, assume it's worth $100,000–$140,000 because of the risk that the company never IPOs or gets acquired. For early-stage startups (Series A), the risk discount should be higher. For late-stage startups (Series C+), it can be lower.

Summary​

Equity grants are long-term, conditional, and illiquid claims on company ownership. RSUs give you shares at vest; options give you the right to buy at a fixed price. Most grants vest over 4 years with a 1-year cliff, meaning you own nothing for a year, then suddenly own 25%, then the rest drips in over 3 more years. The cliff is a retention trap—leave one month too early and you forfeit everything. Vesting acceleration clauses protect you in mergers and layoffs. Grant-date fair value is not the same as actual money in your pocket; it depends on stock price movements between grant and sale. Understand your vesting schedule, negotiate the cliff and acceleration clauses, and don't let unvested equity trap you in a bad situation.
