Equity Vesting Schedule: Your Shares Might Still Be Worthless

The offer looked good. Four-year vesting, one-year cliff, standard terms. You did the rough math on the grant size, felt okay about it, and signed. You filed the grant agreement somewhere you'd definitely be able to find it later. You did not think about it again.

Three years later, the company sells for $180 million. You do the arithmetic. Then you look at your actual payout. It's zero. The investors' preferred stock ate everything above the liquidation floor. Your vested common shares, the ones you stayed four years for, are worth nothing.

This happens regularly. Vesting schedules tell you when shares become legally yours. They do not tell you whether those shares are worth anything, what happens if you leave two months before your cliff, or how 90 days after your last day can wipe out years of compounding value. The offer letter compresses all of this into two lines. Both lines are technically accurate. Neither line is what you thought it said.

Here's what they skipped.

The Calendar Math That Would Have Saved You

The default is four years with a one-year cliff, then monthly vesting afterward. You earn nothing for the first twelve months. On day 366, 25% of your grant vests in one lump sum. Then 1/48th vests each month until you hit four years and the grant is complete.

Put the cliff date in your calendar the day you sign. If you leave on month eleven, you leave with zero equity. If you leave on month thirteen, you leave with 25% of the grant plus two months of post-cliff vesting. The difference between those two outcomes can be worth years of salary. One missed calendar reminder is a very expensive missed calendar reminder.

At public companies the math changes. Google, Meta, Uber, and DoorDash have removed the cliff entirely. RSUs begin vesting from day one, typically on a quarterly schedule. The cliff exists primarily at private companies, where it functions as a retention mechanism. If you're joining a startup or later-stage private company, it's almost certainly there and almost certainly non-negotiable.

The Cliff Is Sharper Than You Think

Companies have terminated employees one day before the one-year cliff. Not as a targeted attack. Layoffs track business cycles and headcount targets, not individual vesting anniversaries. The system doesn't know when your cliff is. The result is the same regardless: eleven months of work, zero equity. Thanks for your contributions.

The cliff also creates a silent exposure at acquisition time. If a company is acquired in month ten and your agreement has no acceleration clause, you likely walk away with nothing. The acquiring company isn't obligated to honor unvested equity unless the original agreement says so.

Two acceleration flavors exist. Single-trigger: your unvested equity vests immediately when the company is acquired. Double-trigger: equity vests only if the company is acquired AND you are subsequently terminated. Single trigger is common for founders and senior executives. Double trigger gets negotiated occasionally for key early hires. For most software engineers on a standard offer, neither applies unless they ask.

Ask explicitly. Read the grant agreement, not just the offer letter. "Standard terms" is not an answer.

The 90-Day Bomb

When you leave a company that granted you stock options (not RSUs), you typically have exactly 90 days to decide whether to exercise your vested options. After that, they expire.

The IRS mandates this window for incentive stock options (ISOs). After 90 days, ISOs automatically convert to non-qualified stock options (NQSOs), taxed as ordinary income rather than at the preferential capital gains rate. You cannot extend this deadline. The conversion happens automatically, on a clock you may not have even known was ticking.

You leave your job and suddenly face a high-stakes financial decision with a 90-day clock. Exercise price, tax liability, possibly alternative minimum tax on ISO spreads, all while you may be between jobs, uninsured, and trying to figure out COBRA. Exercise costs plus taxes frequently run into six figures for engineers at later-stage startups. Fun timing. Optimal conditions for a major irreversible financial decision.

Sam Altman has publicly advocated for 10-year post-termination windows, noting this covers nearly all company exit timelines. Quora was the first to implement a 10-year window, in 2014. Pinterest, Coinbase, Loom, and Amplitude have followed. They remain exceptions.

Before you sign, ask: How long is the post-termination exercise window? Does that window change based on tenure? Some companies offer extended windows only after a minimum tenure threshold.

The Schedule You Think You Have vs. the One You Actually Have

Not all vesting schedules distribute equity evenly. The structure matters as much as the total grant size.

Amazon's standard new-hire RSU grant runs 5-15-40-40: 5% in year one, 15% in year two, 40% in year three, 40% in year four. Engineers who leave at the two-year mark have collected only 20% of their total grant. Amazon historically offsets this with sign-on bonuses in years one and two, but the equity curve is intentionally steep to encourage staying. "Four-year vesting" technically, but most of it is really "stay-until-year-three vesting."

A newer trend runs the opposite direction. Oracle, Airbnb, Nvidia, and Google have moved toward front-loaded schedules, typically around 40-30-20-10. Year one delivers the most equity. Each subsequent year delivers less.

The catch is that front-loaded new-hire grants are smaller, and your later compensation depends entirely on refresh grants. The math works at median performance: the shrinking tail of the new-hire grant gets replenished by annual refreshes. High performers who earn generous refreshes can come out ahead. Engineers who receive small or no refreshes in years three and four often find their equity significantly below what they modeled at signing.

Before accepting a front-loaded offer, ask: What's the typical refresh grant at my level? How are refreshes determined, and by whom? "Performance-based" without specifics is not an answer.

"Vested" Does Not Mean "Valuable"

When a startup raises venture capital, investors typically receive preferred stock. Common stockholders, which includes employees with vested options or RSUs, hold a different class. In an acquisition, preferred stockholders get paid first. Common stockholders get whatever remains.

If a startup raised $150 million and sold for $130 million, preferred shareholders may recover most of their investment. Common shareholders may receive nothing. The gap between the last valuation and the actual exit price falls almost entirely on common stock. Many companies sell at discounts to their last round, particularly after market corrections.

Your equity can be zero not because the company failed, but because it sold for slightly less than it raised. The press release will describe this as a successful exit.

A separate issue at PE-backed companies: repurchase rights on vested shares. Some agreements allow the company to buy back your vested shares at the original strike price when you leave, regardless of current fair market value. You exercise, pay the price, watch shares appreciate, resign, and the company buys them back at what you originally paid. This is increasingly common as private equity has entered later-stage tech. Congratulations on your entirely theoretical gains.

Neither of these appear in "4-year vesting, 1-year cliff."

What to Ask About Your Vesting Schedule Before You Sign

Most negotiation attention goes to grant size. These questions matter more for understanding what you're actually accepting.

What is the post-termination exercise window? The standard is 90 days. Some companies offer more. If options are a meaningful part of your compensation, this shapes your entire exit calculation.

Does the agreement include acceleration provisions, and do they apply to me specifically? Ask for this in writing. "Standard terms" is not an answer. Double-trigger acceleration after an acquisition is the baseline worth asking for.

What is the company's capital structure? You won't get a detailed cap table, but you can ask roughly how much has been raised, whether investors hold participating preferred shares, and what the most recent 409A valuation was. A company that can't answer at a high level is a signal.

Are there any repurchase rights on vested shares after I leave? It feels adversarial to ask. Ask anyway.

What is the refresh grant policy, and what determines the amount? Especially important at front-loaded companies.

One more: if you receive restricted stock (not options) and the company offers early exercise, you have a 30-day window from the grant date to file an 83(b) election with the IRS. This election taxes you now on the current (usually low) value rather than at each future vesting event. Thirty days. No extensions. The IRS does not care that you were busy. Set the calendar reminder the day the paperwork arrives.

The equity conversation is part of the offer negotiation, not a separate administrative step you get to later.

The Short Version

The cliff is binary. Eleven months earns you nothing. One day over the year earns you 25% plus one month.
Acceleration is not automatic. If the company is acquired before your cliff with no acceleration clause, you may leave with nothing.
Options expire 90 days after you leave unless the company offers an extended window. ISOs convert to NQSOs after the deadline, permanently. The tax treatment changes. You cannot unwind it.
Back-loaded schedules (Amazon 5-15-40-40) concentrate most equity in years three and four. Front-loaded schedules (40-30-20-10) pay more upfront and depend entirely on refresh grants.
Preferred stockholders eat first. Your vested common shares can be worth zero even in an acquisition that sounds large.
Repurchase rights can let the company buy back vested shares at the original price when you leave.
83(b) elections have a 30-day hard deadline. No exceptions. Not even good ones.

The offer letter compresses years of financial outcomes into two lines. Reading those lines carefully, asking the questions they skip, and yes, reading the actual grant agreement before you sign, is worth the awkwardness. Your future self, sitting across from the zero-payout spreadsheet, will agree.
