Equity Vesting Schedules Explained for Non-Finance People

When a company offers you equity - usually in the form of stock options or restricted stock units (RSUs) - it doesn't all become yours on day one. Vesting is the schedule by which you earn ownership of that equity over time. If you leave before your equity vests, you typically lose the unvested portion.

The mechanics matter a lot because equity can represent a significant portion of total compensation. Understanding your vesting schedule is as important as understanding your salary.

The most common vesting schedule in tech is a four-year vest with a one-year cliff. Here's what that means: you receive none of your equity for the first year (the cliff). After twelve months, 25% of your total grant vests at once. Then the remaining 75% vests in monthly or quarterly increments over the next three years.

The cliff exists to ensure that employees who leave very quickly don't walk away with meaningful equity. If you leave at month eleven, you get nothing. If you leave at month thirteen, you keep the 25% that vested at month twelve but nothing more. This is why the cliff creates a powerful incentive to stay through at least the first year.

Stock options give you the right to buy shares at a fixed price (the strike price) at some point in the future. If the company's share price rises above the strike price, you can buy shares at the lower price and either hold them or sell them at a gain. If the share price doesn't rise above the strike price, the options are worth nothing. Options are most common in early-stage startups and have significant tax complexity.

Restricted Stock Units are simpler: they're a promise to give you a certain number of shares at vesting. Unlike options, they don't require you to 'exercise' them with cash, and they have value as long as the stock has value. RSUs are standard at public companies and later-stage startups. The key tax point: RSUs are taxed as ordinary income at vesting, at the value of the shares on that day.

For public company RSUs, the math is relatively straightforward: shares times current price gives you current value. For private company equity, it's much harder - the value is real only if the company exits (is acquired or goes public) and does so at a price above your strike price. Treat private company equity as speculative value, not guaranteed compensation.

Ask how many total shares are outstanding, not just how many you're receiving. A grant of 10,000 shares means very little without knowing what percentage of the company that represents. The percentage - and the implied valuation - is what determines the potential value of your stake.
