What Is Equity Vesting?

Vesting defines how ownership of stock options or equity is earned over time. Common in startups, it ensures alignment between employees and company success. Typically, options vest over 4 years with a 1-year cliff.

Cliff Period Explained

The cliff is the minimum time you must stay before any shares vest (e.g., 1-year cliff with 4-year total vesting). If you leave before the cliff, you get no equity. After the cliff, vesting occurs gradually.

Formula Overview

Shares Vested per Period = Total Shares / Total Periods After Cliff

Estimated Value = Shares Vested × Current/Projected Share Price
