Vesting
The plain answer
Section titled “The plain answer”Vesting is the process of gaining ownership of money your employer contributes to your 401(k). Your own contributions are always yours. Employer contributions may become yours immediately or over time, depending on the plan.
How it actually works
Section titled “How it actually works”A plan’s vesting schedule tells you how long you must work before you own employer contributions.
- With immediate vesting, you own employer contributions as soon as they enter your account.
- With cliff vesting, you own none of the affected employer contributions until you reach a set service milestone. You then become fully vested at once.
- With graded vesting, you gain ownership in portions over several service milestones until you are fully vested.
Vesting usually applies to employer money, including an employer match. It does not reduce the amount you contributed from your paycheck.
What this means for you
Section titled “What this means for you”Check your plan’s vesting schedule before treating the full account balance as money you own. If you leave your job, you keep your contributions and the vested portion of employer contributions. The plan can generally take back the unvested portion.
Leaving a job does not mean you need to make an immediate, rushed account decision. First confirm your vested balance, then compare the plan’s available options, fees, and rollover rules.
