Defined Benefit or Defined Contribution Retirement Plan: Which is Right for Your Business?
The retirement plan structure you choose impacts cost, risk and employee outcomes. Here’s what plan sponsors need to know about the pros and cons of defined benefit and defined contribution plans.
A retirement plan is only as valuable as the results it delivers. The structure you choose as a plan sponsor shapes everything from employee participation to your fiduciary exposure — and those decisions are harder to undo than they are to get right the first time.
For example, defined benefit and defined contribution plans take two distinct approaches to retirement savings, differing in who funds the plan, who carries the risk and who’s accountable in the end.
To make the right call for your organization, it’s important to understand both.
Who's responsible for what?
With a defined benefit plan (also known as a pension), the company funds the plan, manages the investments and guarantees a specific monthly benefit at retirement, using a formula based on salary, age and years of service. Employees know what they'll receive, and the employer is responsible for delivering it.
With a defined contribution plan (a 401(k), for example), the dynamic shifts. Employees choose how much to contribute from their paycheck and select their investments, and employers may match contributions up to a limit. The account balance reflects contributions and investment performance.
Defined benefit plans: Predictability at a price
For employees, a pension offers certainty. A fixed monthly income for life removes market risk from the retirement equation. That predictability can be valuable for long-tenured employees and those approaching retirement age who have less time to recover from a down market.
For employers, defined benefit plans are the most expensive retirement plan structure available and the most complex to administer. Employers must ensure the plan is adequately funded to meet future obligations, and if investment returns fall short, costs can escalate quickly.
What do defined benefit plans do well?
Provide a reliable, predictable income stream for retirees
Allow higher contribution and deduction limits than most plan types
Reward long-term employees through formulas that weight years of service
Remove investment decisions from employees
Where do defined benefit plans fall short?
Costly and complex to administer and maintain
Limited portability, meaning employees who leave before vesting may forfeit accrued benefits
Excise taxes apply if minimum contribution requirements aren't met, or excess contributions are made
Many private employers have frozen or terminated pension plans due to long-term funding pressures
Defined contribution plans: Flexibility and shared responsibility
Defined contribution plans put more power in employees' hands. Employees who contribute consistently, invest wisely and take advantage of employer matching can build substantial retirement savings over a career. Contributions can also have tax advantages, and savings can move with employees from company to company.
The tradeoff is that outcomes are never guaranteed. Poor savings habits, underinvestment or market downturns can affect what's available at retirement.
What do defined contribution plans do well?
Give employees portability and control over their investments
Allow for employer matching, which can drive participation and engagement
Are less costly and complex to administer than defined benefit plans
Where do defined contribution plans fall short?
Retirement outcomes depend on employee behavior and market performance
Employees with limited financial knowledge may invest poorly
Require ongoing plan design support and employee education to be truly effective
Common questions from plan sponsors
Q. We currently offer a defined contribution plan. Is there any reason to consider adding a defined benefit component?
A. Some employers may benefit from a hybrid approach that pairs a modest defined benefit with a defined contribution plan. This can offer the retention and predictability benefits of a pension while keeping costs more manageable than a standalone defined benefit plan.
Q. Our employees don't seem engaged with our 401(k). Would a defined benefit plan change that?
A. Lack of participation in a defined contribution plan is usually a design and education challenge. Features like automatic enrollment, automatic escalation and personalized financial wellness guidance can help improve both participation and contribution rates.
Q. Is one plan type more effective for attracting and retaining people?
A. It depends on the workforce. Defined benefit plans tend to appeal most to employees seeking long-term stability with a single employer. Defined contribution plans offer portability and control, and may resonate in a workforce where people expect to change jobs multiple times over the course of their career.
There’s no one-size-fits-all answer
When it comes to retirement plans, the right choice depends on your workforce demographics, business goals, resources and budget.
