The offer letter says something thrilling — “$160,000 in RSUs” — and then the paperwork arrives, dense with defined terms, and the thrill turns into a quiet question: what do I actually have? Here is the whole picture for a first-time recipient: what the grant is, the calendar it lives on, the day money first appears, and the short list of moves worth making in year one.
What you actually have today
A restricted stock unit is the company’s contractual promise to deliver one share later if conditions — almost always continued employment — are met. Until a vesting date passes, you own no shares, cast no votes, and (typically) earn no real dividends. The grant is best understood as scheduled future bonuses denominated in shares. That framing answers most beginner questions instantly: Can I sell them? (Not yet — nothing exists to sell.) Can I lose them? (Yes — by leaving before they vest.) Are they worth the offer-letter number? (Only at the grant-date price; reality will differ at every vest.)
The four numbers to extract from the paperwork
- Total units. Offer value ÷ grant price, roughly. 1,600 units from a $160k grant at $100.
- The schedule. Four years is standard; the rhythm after the cliff is usually quarterly (sometimes monthly). “25/25/25/25 with a one-year cliff, quarterly thereafter” means nothing for 12 months, then 400 units at once, then 100 per quarter.
- The cliff. The waiting period before anything vests at all. Leaving at month 11 of a one-year cliff forfeits 100% — a fact worth knowing before resigning in month 11.
- Special clauses. Search the plan for what happens on termination, change of control (acquisition — “double-trigger” acceleration is common), and leave of absence. Two minutes now prevents folklore later.
Vest day, hour by hour
Suppose 100 units vest on a day the stock opens at $120:
- $12,000 becomes W-2 income automatically. No form to file, no button to press; payroll already knows.
- Withholding fires. Most plans run sell-to-cover: roughly 30-40 of your shares are sold within a day or two and the cash goes to the IRS and your state. Federal withholding is usually the flat 22% — often less than you will really owe, the famous withholding gap.
- The remainder lands in the brokerage account your company’s plan uses (Fidelity, Schwab, E*TRADE/Morgan Stanley are common). Those shares are ordinary stock now, with a cost basis of $120.
Write down the vest price. Each vest’s price × shares is your cost basis, and the broker’s January tax form will probably report it as $0. Future-you, sitting in tax software, will thank present-you for a one-line spreadsheet. (Why this matters: the $0 cost-basis trap.)
How to think about the value (especially vs. a job offer)
Unvested RSUs are real but conditional. Three honest adjustments when comparing offers or planning life:
- Haircut for retention risk. If there’s a meaningful chance you leave within the cliff, year-one equity value is closer to zero than to the headline.
- Volatility cuts both ways. A 4-year grant in a volatile stock can double or halve; budget essentials on salary, treat vests as variable bonuses.
- Refreshers exist. Established companies often layer new annual grants on top, so total vesting income in year 3-4 can exceed the original schedule. Ask how refreshers work where you are.
Reading a real grant
Offer: $160,000 RSU grant, stock at $100 → 1,600 units, 4-year quarterly vest, 1-year cliff. Month 12: 400 units vest at $90 → $36,000 W-2 income, ≈140 shares sold for taxes, ≈260 shares kept (basis $90). Each following quarter: 100 units at whatever the price is. If the stock sits at $130 by year two, each quarter delivers $13,000 of income — and the “$160k grant” is quietly outperforming its label. At $60 it underperforms it. Both outcomes are normal.
The year-one checklist (an hour, total)
- Log into the equity portal; confirm units, schedule and cliff match the offer.
- Open/activate the linked brokerage account before the first vest, not after.
- Ask one question of HR/stock-plan: “What withholding method and rate apply to vests, and can I elect higher?”
- Pick a default policy now — e.g., “sell everything at vest” or “keep 25%, cap company stock at 10% of net worth.” Pre-commitment beats vest-morning improvisation; the trade-offs are laid out in concentration risk.
- Calendar the vests and, if your income is high, the estimated-tax dates from the withholding-gap guide.
Three myths to retire on day one
“I shouldn’t sell or I’ll owe huge taxes.” The income tax is owed at vest whether you sell or not; selling immediately adds roughly nothing. “Holding a year makes the vest tax-free-ish.” The clock only affects growth after vesting. “RSUs are like options.” No strike, no exercise, no expiry, no leverage — different machine, different manual. You now have the manual.
Key takeaways
- Your grant has four numbers that matter: total units, vest schedule, cliff date, and (for valuing the offer) the grant-date price — but future value depends on the price at each vest, not at grant.
- Nothing is yours until it vests; leave before the cliff and the entire grant evaporates legally and normally.
- On each vest day, the value of vested shares becomes taxable W-2 income automatically and some shares are typically sold for withholding.
- Unvested RSUs are a retention tool, not a bank balance — value them with a haircut when comparing job offers.
- Year-one homework is small: confirm the schedule in your equity portal, set up the brokerage account, learn your plan's withholding method, and decide a default sell/hold policy in advance.
Frequently asked questions
My offer letter says $200,000 of RSUs. Is that what I'll get?
It's the grant-date value, usually converted to a fixed number of units at or near your start. What you receive at each vest is units × that day's price — more if the stock rises, less if it falls. The dollar figure in the offer is a snapshot, not a promise.
What happens to unvested RSUs if I quit or am laid off?
In standard plans they are forfeited — that's the point of vesting. Some companies accelerate vesting on layoffs, death/disability, or acquisition ('double-trigger' clauses); your plan document is the only authority.
Do RSUs pay dividends?
Unvested units often accrue 'dividend equivalents' that pay out when the underlying units vest, but many plans pay nothing on unvested units. Vested shares you keep are normal stock and receive normal dividends.
Should I sell my shares as soon as they vest?
Selling at vest costs essentially nothing extra in tax (income tax was due regardless; immediate sale has ~zero gain) and resets your concentration. Holding is choosing to invest a fresh, fully-taxed bonus in one stock. Decide your default policy once, calmly, before the first vest — not at 9:31am on vest day.
