Chapter 2: Vesting: the four-year treadmill
On Wei's first day, the equity portal shows his grant in full: 4,000 RSUs, worth $200,000 at the grant price. It also shows a second number, and the second number is zero. That is his vested balance, the part he actually owns, and it will stay at zero for exactly 365 days.
Vesting is the schedule on which promised equity becomes yours. It is the retention machine from chapter 1 made concrete: the company spreads your grant across years so that every month you stay earns another slice, and every month you might leave puts a price on the door. Understanding the schedule is not optional. It decides what you are paid this year, what you forfeit if you quit, and what a competing offer has to beat.
The cliff, then the drip
The standard schedule in tech is four years with a one-year cliff. Nothing vests during the first 12 months. On the one-year anniversary, 25% of the grant vests all at once. After that, the rest drips in monthly, usually 1/48th of the grant per month for the remaining 36 months.
For Wei, the cliff means $50,000 of stock (1,000 shares at the grant price) lands on his first anniversary, followed by about $4,167 of stock each month for three more years. The cliff exists so companies do not hand equity to people who leave in month four. It also means that quitting in month 11 pays exactly the same equity as quitting in month one: nothing. If you are unhappy at month 10, that math deserves a seat at the table.
One wrinkle matters more than people expect. The grant was denominated in dollars, but it vests in shares. Wei vests 1,000 shares at his cliff no matter what the price is that day. If the stock has climbed from $50 to $65, his cliff vest is worth $65,000. If it has dropped to $35, the vest is worth $35,000. The $200,000 in his offer letter was a snapshot, not a contract for dollars.
The staircase above assumes a flat stock price, which never happens. The calculator below shows the same grant under a rising, flat, or falling price, and it is worth two minutes of your time. A grant that vests into a rising stock can quietly double; the same grant in a falling stock can pay half of what the offer letter implied. Both outcomes are normal.
Refreshers: the ladder effect
If a four-year grant were the whole story, everyone's equity pay would hit zero at month 49. Healthy companies prevent that with refresher grants: new, smaller grants issued along the way, each on its own four-year schedule. Stack a few of them and your vesting turns from a single staircase into an overlapping ladder.
Watch it build for Wei. Suppose his company grants him an $80,000 refresher at the start of each year from year two onward, each vesting evenly over four years at $20,000 per year. His annual vesting now looks like this, valued at grant prices:
| Grant | Year 1 | Year 2 | Year 3 | Year 4 | After year 4 | Grant total |
|---|---|---|---|---|---|---|
| Initial grant ($200,000) | $50,000 | $50,000 | $50,000 | $50,000 | $0 | $200,000 |
| Refresher, start of year 2 | $0 | $20,000 | $20,000 | $20,000 | $20,000 | $80,000 |
| Refresher, start of year 3 | $0 | $0 | $20,000 | $20,000 | $40,000 | $80,000 |
| Refresher, start of year 4 | $0 | $0 | $0 | $20,000 | $60,000 | $80,000 |
| Total vesting | $50,000 | $70,000 | $90,000 | $110,000 | $120,000 | $440,000 |
His equity pay climbs every year: $50,000, then $70,000, then $90,000, then $110,000. Year four is the peak, with four grants vesting at once on top of his salary. People call this the golden handcuffs zone, and the name is earned. Leaving in year four means abandoning the fattest vesting year of the ladder, which is precisely the design.
The ladder has a back side. If the refreshers stop after year four, the initial grant finishes and the ladder unwinds: $60,000 vests in year five, $40,000 in year six, $20,000 in year seven, and then nothing. That $120,000 tail sounds comfortable until you notice the trend. An engineer whose vesting drops from $110,000 to $60,000 has taken a $50,000 pay cut without anyone saying the words. This is why experienced people ask about refresh policy before joining and check their ladder every year: future-year vesting that looks thin is a pay cut already in motion, and the time to fix it (through a refresh conversation or a new job) is before the fat years end.
Unvested means not yours
The hardest discipline in equity compensation is refusing to count chickens. Unvested equity is a forecast of future pay, conditional on you staying and the company keeping you. It is not savings, not net worth, and not collateral. Budget on your salary and on shares that have actually vested.
The forecast still has a price, and you should know it whenever a recruiter calls. At the end of year two, Wei has vested $120,000 of his ladder. Left on the schedule are $100,000 from his initial grant and $60,000 from his first refresher: $160,000 of unvested equity over roughly the next three years, before counting any future refreshers. A competing offer that ignores that $160,000 is asking him to donate it. The standard fixes are a signing bonus, a larger initial grant, or both, and good recruiters expect the conversation. Walking away from unvested equity for a better role can absolutely be the right call. Doing it without pricing the forfeit is just carelessness.
Budget on salary and vested shares only. Before any job change, total the unvested ladder you would forfeit over the next two to three years and make the new offer answer for it, in signing bonus or grant size, in writing.
Double-trigger RSUs: vested but frozen
Private companies that grant RSUs usually add a second condition. Double-trigger RSUs require two events before the shares are truly yours: the time-based vesting you already know, plus a liquidity event such as an IPO or acquisition. Until both triggers fire, you owe no tax and you own no sellable shares, even after years of "vesting."
Sam, a director at a late-stage private company, has satisfied the time trigger on thousands of RSUs over six years. His portal shows a seven-figure value. His bank account shows none of it, because the second trigger (an IPO) has not fired. The design protects him from one cruel outcome: being taxed on shares he cannot sell. The cost is limbo. His equity is real enough to keep him from leaving and unreal enough that he cannot spend a dollar of it, and when the IPO finally fires the second trigger, years of vests will land as taxable wages all at once. Chapter 11 walks through that avalanche.
If you hold double-trigger RSUs, two chapters are yours: chapter 9 on paper money, and chapter 11 on the IPO-day tax event.
When the schedule breaks
Vesting schedules assume a steady job at a steady company. Three events interrupt them, and the grant agreement decides each one, so read yours before you need it.
Layoffs, acquisitions, and death
Layoffs. Unvested equity is usually forfeited on your termination date. Severance packages sometimes include extra months of vesting or acceleration of the next vest date, and this is negotiable, so ask before signing anything. Vested shares remain yours.
Acquisitions. Your unvested grant is typically assumed (converted into acquirer stock on the same schedule), cashed out, or accelerated. Some grants vest early on the deal alone; others require the deal plus losing your job. Chapter 11 defines these single and double triggers and what to check in your documents.
Death. The plan documents control whether unvested equity accelerates, transfers to your estate, or lapses. Make sure your beneficiaries and your records are in order; the Finvest Personal Finance Guide covers the estate side.
Where people go wrong
- Spending the grant before it vests. A $200,000 grant supports exactly $0 of spending in year one. Budget on cash.
- Quitting at month 10 or 11. Months from a cliff, timing matters. Sometimes leaving now is still right, but decide with the $50,000 on the table, not in ignorance of it.
- Reading the offer-letter value as fixed. Shares vest, not dollars. Run your grant through the calculator under a falling price before you anchor on the headline.
- Missing the ladder's back side. A thin refresher year is a future pay cut. Check next year's scheduled vesting every January, while there is still time to act.
- Changing jobs without pricing the forfeit. The unvested ladder is the real cost of moving. Make the new offer pay for it explicitly.
Key takeaways
- Vesting converts a promise into property on a schedule, typically four years with a one-year cliff: nothing for 12 months, then 25%, then monthly.
- Shares vest, not dollars. Vest-day prices set what you are actually paid, so the offer-letter value is a snapshot.
- Refreshers stack into a ladder. Wei's peaks at $110,000 in year four; if refreshers stop, vesting slides to $60,000, $40,000, then $20,000. Watch the back side of your own ladder.
- Unvested equity is forfeited when you leave. Price it into every competing offer, and budget only on salary and vested shares.
- Double-trigger RSUs at private companies need vesting plus a liquidity event; layoffs, acquisitions, and death are all governed by the plan documents, so read them early.
