Defined contribution plans over four times more available than defined benefit plans
In March 2023, 70 percent of workers in private industry had access to a retirement plan and 53 percent were participating in a retirement plan. Sixty-seven percent and 15 percent of private industry workers had access to defined contribution and defined benefit plans, respectively. Some workers had access to more than one type of plan. There are several key differences between defined benefit and defined contribution plans, namely: portability, cost to employees, who bears the risk, how they are paid out, eligibility requirements, and what is guaranteed.
In the case of defined benefit plans, the benefit amount is guaranteed, typically not portable, employers are normally the only contributors, and it is paid out in regular intervals after an employee retires. Since the defined benefit amount is guaranteed, the risk is borne by the employers. ERISA created the Pension Benefit Guaranty Corporation (PBGC) to protect the benefits in defined benefit plans. Defined contribution plans are also covered by ERISA, but since there is no benefit amount guaranteed, no entity exists to ensure their protection because the amount fluctuates based on the value of the investment and contributions made over the years. Employers and employees can contribute to this plan type and eligible benefits are portable from employer to employer.
