The advantages of 401 k are that they save automatically, they might have a match from their employer, and they have the possibility of portfolio growth. 401k's benefits are well known to many workers: it's easy and regular pay. Others will wonder, does 401k accrue interest, though growth typically is based on investment performance, not fixed interest. When employees grasp the advantages of a 401 k plan, they can plan with confidence for retirement and financial security.
