What Is Vesting? How Cliff and Graded Schedules Affect Your Job Decisions

Vesting is the process by which employer-granted equity or 401(k) matching contributions become legally yours over time. Before you are vested, those assets belong to the employer — leave before the vesting date and you forfeit them entirely. After vesting, they are yours regardless of when you leave. A 4-year cliff vest on a $40,000 RSU grant means you own $0 on day 364, and $40,000 on day 366. Understanding your vesting schedule is one of the highest-value parts of reading a job offer.

The two types of vesting schedules

What vests and what doesn't

Your own contributions to a 401(k) are always immediately and fully vested — by law (ERISA). You can never lose the money you personally contributed. What vests on a schedule is exclusively employer contributions — the match, profit sharing, or employer stock grants:

• 401(k) employer match: Most commonly subject to 1–3 year cliff or 2–6 year graded vesting.
• RSUs (restricted stock units): Typically vest over 4 years — often 25% per year or 1-year cliff then monthly/quarterly after.
• Stock options: Similar 4-year schedule; options must also be exercised (you pay the strike price) within a window after vesting.
• Profit sharing: Subject to a plan-specific vesting schedule, often 3–6 years graded.

How 401(k) vesting works in practice

Example: Your employer matches 100% of your contributions up to 5% of salary ($80,000 salary = $4,000 employer match per year) with a 3-year graded schedule: 33% vested after year 1, 66% after year 2, 100% after year 3.

Leaving 30 days before the year-2 anniversary in this example costs you $5,280 − $1,320 = $3,960 in employer match forfeiture. Always check the exact vesting anniversary date — it is rarely exactly 12 months from hire date.

RSU vesting: how tech company equity typically works

At most publicly traded tech companies, RSUs vest on a 4-year schedule with quarterly vesting after a 1-year cliff:

• Grant date: Employer grants 1,000 RSUs at $40/share ($40,000 value at grant)
• Year 1 cliff: 250 RSUs vest (25%) at current share price
• Years 2–4: 62.5 RSUs vest each quarter (6.25% per quarter)
• Tax event: At each vest, the shares' market value is treated as ordinary income — this is taxable income in the year of vesting regardless of whether you sell

When evaluating RSU offers, always model the value at current share price, not the grant price. A $40,000 RSU grant where the stock has risen to $80/share is worth $80,000 in tax liability at vest. Use our 401(k) Calculator to model pre-tax retirement savings alongside equity compensation.

How vesting affects job change decisions

Before leaving any job, calculate the full cost of unvested compensation:

1. Ask HR for your exact vesting schedule and anniversary dates.
2. Calculate the dollar value of unvested 401(k) match and equity at current market price.
3. If starting a new job: does the offer include a signing bonus to offset unvested compensation at your current job? Many employers will cover forfeited vesting to attract talent.
4. Model the total package: new salary × 4 years + signing bonus + new equity grant vs current package × 4 years + value of unvested compensation you are leaving behind.

A common mistake: employees leave 1 month before a cliff vest worth $15,000–$50,000 because the new job's start date is fixed. An additional 30 days at your current job could be worth tens of thousands — always negotiate start dates with this in mind.

Key takeaways

• Your own contributions always vest immediately. Only employer contributions (match, RSUs, profit sharing) vest on a schedule.
• Cliff vesting: 0% until the cliff date, then 100% at once — leaving one day early can mean $0 from your employer.
• Graded vesting: partial ownership accrues each year — less catastrophic to leave early, but still costly.
• Before accepting a new job offer, calculate the dollar value of unvested compensation you are leaving — and negotiate a signing bonus to offset it if possible.
• RSU vests are a taxable event in the year they occur — plan for the tax withholding with your payroll department.

Frequently asked questions

What does vesting mean?

Vesting is the schedule by which employer contributions (401k match, RSUs, stock options) become permanently yours. Before vesting, those assets belong to the employer and are forfeited if you leave. Your own contributions are always immediately vested — by law.

What is cliff vesting vs graded vesting?

Cliff vesting: 0% until a specific date, then 100% instantly (e.g., 1-year cliff means you own nothing until day 366, then everything). Graded vesting: a percentage vests each year (e.g., 25% per year for 4 years). Cliff is all-or-nothing risk; graded spreads the risk across years.

What happens to unvested 401(k) match when I leave my job?

Unvested employer match is forfeited — it goes back to the employer. Only your own contributions are always yours. Check your plan's vesting schedule in your benefits portal or by asking HR before scheduling your last day, especially if a cliff date is approaching.

Do RSU grants vest differently than 401(k) match?

Typically yes. 401(k) match often uses a 1–3 year cliff or 2–6 year graded schedule. RSUs at tech companies typically use a 4-year schedule with a 1-year cliff (25% at year 1, then quarterly or monthly for years 2–4). RSUs are also taxable as ordinary income in the year they vest, unlike 401(k) contributions.

How do I know my vesting schedule?

Check your offer letter, benefits enrollment summary, or equity award agreement. For 401(k) match vesting: look in your plan documents or benefits portal. For RSUs and options: check your equity management platform (Carta, Schwab Equity Awards, Morgan Stanley equity admin) or ask HR for your grant details.
