What is vesting and cliff in equity compensation?
Short Answer
Vesting is the gradual earning of equity over time (typically 4 years). A cliff is a waiting period (usually 1 year) before any equity vests — protecting the company from employees leaving immediately with full grants.
Full Explanation
An employee is granted 40,000 options with a 4-year vest and 1-year cliff. This means: in year 1, if they leave, they forfeit all options (cliff). After 1 year, 10,000 options are earned (25% cliff vest). Monthly, they earn 833 additional options (1/48th of 40,000 per month). After 4 years, all 40,000 are earned and fully vested. The cliff protects companies from early departures; the monthly vesting encourages long-term commitment. A 4-year vest with 1-year cliff is standard in VC-backed companies. Some companies use 3-year vests (startup churn reality), and early employees sometimes negotiate shorter vests. Accelerated vesting clauses (e.g., double-trigger acceleration where equity vests faster if the company is acquired) are common for founders and senior hires. For employees, understanding vesting is essential: if you leave after 18 months of a 4-year vest, you only have 25% vesting benefit. Many startup failures are partly driven by incentive misalignment — employees chasing cliff vests rather than long-term value creation.
