Vesting schedules explained: cliff, graded, and the 4-year standard

A vesting schedule determines how and when equity ownership is earned over time. The most common structure in startups is a four-year graded schedule with a one-year cliff, but it’s not the only option — and choosing the wrong type can cost you talent, control, or both.

If you’re a founder deciding how to structure equity for yourself, your co-founders, or your first hires, the vesting schedule is one of the most consequential decisions you’ll make. It determines what happens when someone leaves, how motivated people stay, and what your cap table looks like when investors show up.

This guide covers every major type of vesting schedule, when each one makes sense, and the specific numbers behind them. If you’re looking for the basics of how vesting works, start with our vesting explainer. This post goes deeper into the schedule types and how to choose between them.

What is a vesting schedule?

A vesting schedule is a timeline that dictates when equity ownership transfers from the company to an individual. Until equity vests, the company can typically reclaim it if the person leaves.

The core idea: equity is earned, not given. Instead of granting someone 20% of the company on day one, a vesting schedule ensures they earn that 20% gradually by continuing to contribute over time.

Every vesting schedule has a few key parameters:

The 4 types of vesting schedules

1. Cliff vesting

With cliff vesting, nothing vests until a specific date. Then a large chunk (or all) of the equity vests at once.

How it works: A founder is granted 25% of the company with a one-year cliff. For the first 12 months, they own nothing. On their one-year anniversary, the full 25% vests immediately.

Pure cliff vesting (where 100% vests at the cliff) is rare in startups. It’s more common in corporate retirement plans and 401(k) matching. What startups typically call “cliff vesting” is actually a cliff followed by graded vesting — the hybrid model described below.

When to use pure cliff vesting:

• Advisor grants with short time horizons
• Project-based contributors with a defined end date
• Trial periods where you want all-or-nothing commitment

The risk: If someone leaves one day before the cliff, they get zero. One day after, they get everything. This creates a perverse incentive to stay just past the cliff date and then leave.

2. Graded vesting

Graded vesting transfers equity in regular increments over time. In its pure form (no cliff), it’s common in corporate settings but less common in startups on its own.

How it works: A founder is granted 25% of the company that vests monthly over 4 years. Each month, 1/48th of their equity vests. After 24 months, they’ve earned 50% of their allocation.

When to use graded vesting:

• Employee stock option plans
• Co-founder equity when you want smooth, predictable ownership transfer
• Situations where you want departures to be “clean” at any point

The benefit: No cliff anxiety. Every month of work earns proportional equity. People who leave at month 18 keep exactly 18 months’ worth.

The risk: Without a cliff, someone who leaves after one month still walks away with equity. For co-founders, that’s usually too generous. That’s why most startups combine graded vesting with a cliff.

3. Cliff + graded vesting (the industry standard)

This is what most people mean when they say “4-year vesting with a 1-year cliff.” It combines the protection of a cliff with the predictability of graded vesting.

How it works:

• Year 1: Nothing vests (the cliff)
• Month 12: 25% vests all at once
• Months 13-48: Remaining 75% vests monthly (about 2.08% per month)

Nearly all venture investors require a four-year vesting schedule with a one-year cliff as a condition of investment. If you’re planning to raise, this is the structure you should default to.

Why this is the standard: The cliff solves the early-departure problem. If a co-founder quits at month 8, they get nothing. But if they stay past the cliff, they earn equity smoothly from there. It balances protection with fairness.

Variations on the standard:

• 6-month cliff: Less common, but some founders negotiate this when they’ve already been working together pre-incorporation
• Quarterly vesting after cliff: Some companies vest every 3 months instead of monthly
• 3-year total duration: Increasingly common for later-stage hires, but investors typically want 4 years for founders

4. Reverse vesting (for founders)

Reverse vesting flips the traditional model. Instead of gradually receiving shares, founders receive all their shares upfront — but the company retains the right to repurchase unvested shares at the original (low) price if the founder leaves.

How it works: A founder is issued 1 million shares at incorporation at $0.001 per share. The shares are subject to a 4-year reverse vesting schedule. If they leave at month 18, the company can repurchase the unvested portion (62.5%) for $625.

Why it exists: Founders need to own their shares from day one for tax purposes. If you receive shares that vest over time, each vesting event is a taxable event. Reverse vesting combined with an 83(b) election lets you pay taxes on the full grant at the low initial value, then owe nothing as shares vest.

Approximately 95% of venture capital term sheets require founder reverse vesting schedules. If you’re raising money, this isn’t optional.

The key difference from standard vesting:

Factor	Standard vesting	Reverse vesting
Share ownership	Gradual transfer to you	You own everything from day one
If you leave early	You keep vested shares	Company repurchases unvested shares
Tax treatment	Each vest is taxable	One-time tax with 83(b) election
Used for	Employees, advisors	Founders
Investor requirement	Expected	Required

When to use reverse vesting:

• Founding team equity, especially when raising institutional money
• When you want to file an 83(b) election to minimize tax exposure
• When all founders should be “owners” from day one for governance purposes

Other vesting structures

Performance-based vesting

Equity vests when specific milestones are hit rather than on a time schedule. Common milestones include revenue targets, product launches, fundraising events, or individual performance goals.

Example: A VP of Sales receives 2% equity that vests in tranches: 0.5% when annual revenue hits $1M, 0.5% at $3M, 0.5% at $5M, and 0.5% at $10M.

When it works: Executive hires at later-stage companies where you want to tie equity directly to results. Also useful for advisors whose value is tied to specific introductions or outcomes.

When it doesn’t: Early-stage startups where milestones are unpredictable. If the goalposts keep moving, performance-based vesting becomes a source of conflict rather than motivation.

Back-weighted vesting

More equity vests in later years. Amazon famously uses this: 5% in year one, 15% in year two, then 40% in each of years three and four.

Why companies use it: Retention. The biggest equity payouts come later, creating a strong incentive to stay. Amazon’s structure specifically discourages the common “vest and bounce” pattern where employees leave after their cliff.

Why startups rarely use it: At early stage, you need people motivated now, not waiting for year three. Back-weighting can feel punitive and makes it harder to compete for talent against companies with standard schedules.

Front-weighted vesting

The opposite of back-weighting: more equity vests early. Some startups grant 40% at the one-year cliff and spread the remaining 60% over years two through four.

When it makes sense: Key hires who need to see significant upside quickly to justify leaving a higher-paying job. Also useful when you want the cliff to feel more rewarding.

How to choose the right vesting schedule

The right schedule depends on who you’re structuring it for and what stage your company is at.

For co-founders

Use reverse vesting with a one-year cliff and file the 83(b) election. Four-year total duration. Monthly vesting after the cliff. This is the structure investors expect, and it protects everyone on the team.

If contributions are unequal or unpredictable, consider dynamic equity during the pre-revenue phase. You can freeze into a fixed cap table with standard vesting when you’re ready to formalize.

For early employees

Standard 4-year cliff + graded vesting. One-year cliff, monthly vesting after. Consider double-trigger acceleration for key hires to protect them in acquisition scenarios.

The equity amount matters more than the schedule here. Use our equity calculator to benchmark against industry norms.

For advisors

Shorter schedules, lighter cliffs. Advisors typically vest over 1-2 years with a 3-month cliff (or no cliff at all). Their equity stakes are smaller — usually 0.25% to 1% — and their commitment is measured in hours per month, not full-time work.

Vesting pitfalls to avoid

Starting vesting at incorporation, not when work began. If your co-founder has been building for 6 months before you incorporate, their vesting should credit that time. Otherwise you’re penalizing the person who started earliest.

Forgetting the 83(b) election. You have exactly 30 days from receiving restricted stock to file. Miss it and every vesting event becomes taxable at fair market value. This single mistake can cost founders tens of thousands of dollars. Read our 83(b) guide.

Using the same schedule for everyone. A co-founder working 60 hours a week needs a different structure than an advisor showing up for monthly calls. Match the schedule to the relationship.

No vesting at all. Research from Noam Wasserman found that half of founding teams didn’t include vesting or buyout provisions in their equity agreements. Those teams were significantly more likely to experience destructive conflict.

Ignoring acceleration. If your company gets acquired and you’re fired the next day, what happens to your unvested shares? Without acceleration clauses, you could lose years of equity. Double-trigger acceleration is the standard protection.

How vesting works with dynamic equity

Traditional vesting assumes you know the equity split upfront. But what if contributions are unequal or unpredictable?

Dynamic equity tracks contributions as they happen — time, money, expertise — and adjusts ownership accordingly. When combined with vesting, you get the best of both worlds:

• Equity reflects actual contributions (no guessing on day one)
• Vesting protects against early departures (no dead equity)
• Everything converts cleanly when you’re ready to freeze into a cap table

This is especially useful when co-founders have different time commitments, one person is investing cash while another invests time, or contributions are likely to shift as the company evolves.

Frequently asked questions

What is the most common vesting schedule for startups?

Four-year graded vesting with a one-year cliff, vesting monthly after the cliff. This structure is used by the vast majority of venture-backed startups and is expected by nearly all institutional investors. After the one-year cliff, 25% of the equity vests immediately, then the remaining 75% vests in equal monthly installments over the next 36 months.

What is the difference between cliff vesting and graded vesting?

Cliff vesting has a waiting period where nothing vests, then a large portion vests all at once. Graded vesting distributes equity in regular increments (monthly or quarterly) over the full schedule. Most startups combine both: a one-year cliff followed by monthly graded vesting. The cliff protects against very early departures, while graded vesting ensures smooth, proportional ownership transfer.

Do founders need vesting?

Yes. Investors require it, and it protects founders from each other. Without vesting, a co-founder who leaves after a few months retains their full equity stake, creating dead equity that dilutes everyone else. Founder vesting is typically structured as reverse vesting combined with an 83(b) election to minimize tax impact.

Can I change my vesting schedule after it’s been set?

Technically yes, but it requires agreement from all affected parties (and potentially board approval if investors are involved). Changing vesting terms retroactively is complicated and can have tax implications. It’s much easier to get the schedule right from the start. If your situation is evolving and the original schedule doesn’t fit, consider whether dynamic equity might be a better framework for the pre-revenue phase.

What happens to unvested shares when a co-founder leaves?

With standard vesting, unvested shares are forfeited. They return to the company and can be reallocated to the remaining founders, new hires, or an option pool. With reverse vesting, the company repurchases unvested shares at the original issue price. In both cases, the departing co-founder keeps only what has vested. Your co-founder agreement should spell out exactly how this works.
