How Equity Compensation Actually Vests

Equity compensation — stock options or restricted stock units offered as part of a job offer — is granted upfront but does not typically become fully owned by the employee immediately. A vesting schedule governs how and when that grant actually converts into shares the employee fully controls.

Understanding how a vesting schedule actually operates explains why the headline equity figure in an offer letter and the amount an employee can actually realize at any given point are often two very different numbers.

How a Vesting Schedule Actually Works

A common vesting structure grants equity over four years with a one-year cliff, meaning no portion of the grant vests during the first year of employment, and then roughly a quarter of the total grant vests at the one-year mark, with the remainder vesting incrementally, often monthly or quarterly, over the following three years.

If an employee leaves the organization before a given vesting date, any unvested portion of the grant is typically forfeited entirely, which is the specific mechanism that creates a retention incentive tied to continued employment over the multi-year vesting period.

Some organizations also offer a shorter or graded vesting schedule for later, smaller equity grants issued to existing employees, sometimes called a refresh grant, which typically vests over its own separate multi-year schedule distinct from the original new-hire grant's timeline.

How Stock Options Differ From Restricted Stock Units

A stock option grants the right to purchase shares at a fixed price, called the strike price, set at the time of the grant, meaning the option's value depends on the company's share price rising above that strike price by the time the employee exercises the option.

A restricted stock unit, by contrast, is a promise to deliver actual shares once vesting conditions are met, without requiring the employee to pay anything to receive them, which structurally removes the strike-price dependency that makes stock options worthless if a company's share price falls below the strike price.

At a privately held company, share price is generally set periodically through an internal valuation process rather than continuously through public trading, which means equity granted at a private company carries additional uncertainty about when, or whether, the shares can actually be converted into cash at all.

Where Equity Compensation Is Commonly Misunderstood

A frequent misconception treats the headline grant value stated in an offer letter as money already available to the employee. In practice, that figure represents an unvested grant subject to continued employment over the full vesting period, and its ultimate realized value for stock options also depends on the company's future share price performance, which is inherently uncertain at the time of the grant.

It's also commonly assumed that vesting schedules are standardized across all employers. In practice, cliff length, total vesting duration, and vesting frequency all vary by company and sometimes by role level, which is part of why comparing two offers' equity components requires looking at the full vesting schedule, not just the headline grant number.

The exercise window for a stock option after leaving a company is a further point of confusion: many plans specify a limited period, often ninety days, in which a former employee must exercise vested options before forfeiting them, a deadline that is separate from the vesting schedule itself.

What Equity Documentation Actually Specifies

A formal equity grant agreement, typically issued separately from the offer letter itself, specifies the exact vesting schedule, the strike price for options if applicable, and the conditions under which unvested equity is forfeited, which is the governing document a departing employee would reference to determine exactly what they retain.

Vesting status is also typically tracked in an equity management platform that the employee can access directly, showing precisely how much of the original grant has vested as of any given date and what remains outstanding on the schedule.

Tax documentation associated with vesting events, issued separately from the equity grant agreement itself, records the value recognized at each vesting date, which is generally the figure relevant for tax reporting purposes rather than the original grant value stated in the initial offer letter itself, which reflects the grant's value at a different point in time entirely.

Equity compensation's actual value to an employee unfolds gradually according to a specific vesting schedule, not immediately upon acceptance of an offer — a mechanism explicitly built to tie realized compensation to continued employment over time.
