When companies offer equity compensation, they quote impressive total values: '$400,000 RSU grant.' But the real value depends entirely on the vesting schedule — when those shares actually become yours. Front-loaded, back-loaded, and cliff vesting all produce different outcomes. Combined with the typical 4-year tenure of tech employees, 'unvested' often means 'never received.' Most equity comp negotiations focus on total grant value while ignoring the vesting structure that determines how much you'll actually get.
Conventional vesting schedules: most large tech companies use 25% per year for 4 years, with quarterly granularity (so you receive 6.25% per quarter after the first year). After a 1-year cliff (you must stay 1 year before any vesting), the remaining 75% vests quarterly. This is the 'Silicon Valley standard' set by Google in the 2000s and broadly adopted.
Concrete example: $400K RSU grant with 1-year cliff and quarterly vesting after that. Year 1: $100K (25%, all on the cliff date). Year 2-4: $100K each year, vesting $25K per quarter. If you leave at the 12-month mark, you get $100K. If you leave at 6 months, you get $0 (didn't reach the cliff). Common scenario: founder/early employee leaves at 11.5 months, gets nothing — happens more often than you'd expect.
Front-loaded vesting (more in early years): 33-40% vests in year 1, declining percentages in years 2-4. Examples: 40/30/20/10 or 33/27/22/18. Companies use this for senior hires they're trying to attract — the early vesting is essentially a sign-on bonus. Best for employees who don't plan to stay 4 years (most don't).
Back-loaded vesting (more in later years): 10/20/30/40 or 15/25/30/30. Companies use this for retention — the big vests are far into the future, incentivizing employees to stay. Net Worse for employees because the early years (when most equity comp is received) have lower vesting. Combined with the typical 2-3 year actual tenure, you get less than half the grant.
Concrete comparison: a $500K grant.
Front-loaded (40/30/20/10): year 1 vest $200K. Year 2 $150K. Year 3 $100K. Year 4 $50K. If you stay 4 years: $500K. If you leave at year 2: $200K + (partial year 2). If you leave at year 3: $200K + $150K = $350K + partial.
Conventional (25/25/25/25): year 1 $125K. Year 2 $125K. Year 3 $125K. Year 4 $125K. If you stay 4 years: $500K. If you leave at year 2: $125K. If you leave at year 3: $250K.
Back-loaded (10/20/30/40): year 1 $50K. Year 2 $100K. Year 3 $150K. Year 4 $200K. If you stay 4 years: $500K. If you leave at year 2: $50K + (partial). If you leave at year 3: $150K + (partial).
Average tech employee tenure is approximately 2-3 years. So in expectation, the front-loaded grant is worth substantially more than the back-loaded grant for the typical employee. But companies advertise these grants as having the same total value — making the comparison misleading.
Cliff vesting: some grants (especially at startups) have all-or-nothing vesting at specific milestones. Common: 1-year cliff (nothing if you leave within 12 months), 2-year cliff (nothing within 24 months), or even longer. This is most aggressive form of retention vesting — it's worth $0 until cliff date, full value after.
Combined with promotion vests: many companies grant additional 'refresh' RSUs annually. So your initial 4-year grant is supplemented with new grants each year. The combined vesting schedule looks like overlapping waves. Net effect: even at year 4, you have substantial unvested equity from year 2-3 grants. This creates 'golden handcuffs' that grow with tenure.
Refresh grant disclosure: some companies are transparent about expected refresh rates ('we typically refresh at 25-35% of new-hire grants annually'). Others don't commit to anything formally. Without refresh transparency, evaluating a grant with the assumption of refreshes is risky. Some companies front-load grants then refresh minimally, leaving you with declining equity income year-over-year.
Stock price volatility: equity comp value depends on stock price at vesting. A $400K grant at $100/share = 4,000 shares. If the stock goes to $200/share, your grant is worth $800K. If it drops to $50/share, $200K. Companies often quote 'target value' assuming current stock price — actual value can differ dramatically by vest date. Risk-adjusted, the grant is worth substantially less than the headline number for any rational employee.
Tax timing: RSUs are taxed at vest as ordinary income. Front-loaded vesting concentrates tax events in early years (when you may be in lower brackets due to fewer years of accumulated grants). Back-loaded vesting delays tax (and value), pushing it into years when you're more likely to be in higher brackets due to compounding refresh grants. Most employees don't think about this impact.
Negotiation tactics: when receiving an offer with vesting structure, ask about vesting schedule. Push for front-loaded if you can — companies sometimes accommodate this for senior hires. Ask about typical refresh percentages. Get specific commitments documented (oral promises about refreshes are not enforceable).
Quitting math: when considering leaving for a new role, calculate the value of unvested equity you'll forfeit. Combined with the cost of moving (relocation, life disruption, social ties, learning curve), this 'leaving cost' often exceeds $200K-$500K for senior tech employees. The new role needs to be substantially more valuable to justify the change.
Risk-adjusted value: if you assume only 60-80% of your grant will actually vest (based on average tech tenure), the real expected value of a $400K grant is $240K-$320K. Plus the volatility of the underlying stock. Treat equity comp values as estimates with significant downside risk, not fixed assets.
