Vesting
The process by which you gain ownership of employer contributions to your retirement plan over time. Your own contributions are always 100% vested immediately.
Vesting refers to your ownership rights over employer contributions to your retirement plan. While your own contributions are always fully vested (you keep them if you leave), employer contributions — matches, profit-sharing, or other employer-funded amounts — may vest over a period of years.
There are two common vesting schedules: cliff vesting and graded vesting. With cliff vesting, you become 100% vested after a set period (typically 3 years), with 0% vesting before that point. With graded vesting, your ownership increases incrementally — for example, 20% per year over 5 years or 33% per year over 3 years.
Understanding your vesting schedule is important when considering a job change. If you leave before being fully vested, you forfeit the unvested portion of employer contributions. Some employers use generous vesting schedules as a retention tool. Once you are 100% vested, those funds are yours regardless of whether you stay or leave.
How it works
Vesting determines when employer contributions to your retirement plan actually become yours to keep. Your own contributions are always 100% vested immediately — no waiting period applies to money that came out of your own paycheck — but money your employer adds, such as a match or profit-sharing contribution, typically vests over time according to a schedule set out in the plan document.
You can generally check your vesting percentage on your plan's online portal or year-end statement, which shows how much of the employer-contributed balance you currently own versus how much is still subject to forfeiture. The two common structures are cliff vesting, where you go from 0% to 100% ownership all at once after a set period, often three years, and graded vesting, where ownership increases gradually over a period the plan defines, commonly somewhere between two and six years.
Vesting matters most when you're considering a job change: leaving before you're fully vested means forfeiting whatever portion of the employer-contributed balance hasn't vested yet, even though the money is already sitting in your account statement. Some employers deliberately use longer vesting schedules as a retention tool, since walking away from unvested matches is a real cost to switching jobs. Once you cross the vesting threshold — whether all at once under a cliff schedule or gradually under a graded one — those funds are permanently yours regardless of what happens afterward.
Example: graded vesting on employer contributions
An employee's plan uses graded vesting spread evenly at 20% per year over five years. After two full years of employment, the employee has accumulated $8,000 in employer match contributions, but is only 40% vested (20% per year times 2 years).
That means $3,200 of the $8,000, 40%, is theirs to keep if they leave the company now, while the remaining $4,800, 60%, would be forfeited. Staying through year five would bring them to 100% vesting, securing the full employer-contributed balance regardless of when they eventually leave.
