In a typical 401(k) plan, an employer might use a five-year graded vesting schedule where the employee becomes 20% vested in the employer contributions each year, starting at the end of the third year of employment. By the end of the fifth year, the employee is fully vested, meaning they have earned 100% ownership of the employer contributions.
Can you check if I am fully vested in my retirement plan yet, or if there are still contributions that are contingent on further service?
