403(b) Participation Rates Reach Record Highs, but Savings Results ‘Still Not Great’

For 403(b) plan sponsors, automatic enrollment helps employees build retirement security, but participation is only half the task facing many, due to low savings rates.
Automatic enrollment, better communication and employer matching contributions are driving 403(b) retirement plan participation rates higher, but greater participation is not always resulting in better retirement preparedness.

An average of 83.1% of eligible, active, nonprofit-organization employees maintained a balance in their plan in 2022, nearly identical to the year before—and up from 76.7% in 2013. Participation rates at nonprofit 403(b) plans have continued to reach record levels, according to data from the Plan Sponsor Council of America.

For 403(b) plans, while increased participation is clearly positive, Kim Cochrane, senior director of client services for Hub International’s Mid-Atlantic region, cautions there may not be cause for celebrating, because there is not yet evidence showing workers are also saving more.

“Automatic enrollment is taking a good solid market share in the 403(b) world. … It is probably single-handedly contributing to the increase to participation of employees in 403(b)s,” she says. “Now, that [increase] does not mean they are saving enough money; it just means they are saving something.”

Participation rates increased due to “auto-enrollment, better communications, [and] the [employer’s] match may have a role,” says Robyn Credico, defined contribution practice leader for North America at Willis Towers Watson.

A growing number of 403(b) plans use auto-enrollment: Use of the feature increased by almost 20% in 2022, and it was used in 31.4% of 403(b) plans, up from 26.5% the year before, PSCA data show. In 2013, 16.0% of 403(b) plans used auto-enrollment.

Within 403(b) nonprofit plans, health care and K-12 education retirement plans experienced the largest increases in 2022, says Hattie Greenan, director of research and communications at PSCA, which is part of the American Retirement Association. Voya Financial 403(b) plans experienced a 38% increase in plans using auto-enrollment in 2023, according to Voya data.

Behavioral finance techniques provided the fuel for 403(b) plans to boost their participation rates, which “definitely was a primary goal,” says Brodie Wood, Voya’s senior vice president and national practice leader for health care, education and not-for-profit markets.

According to retirement plan adviser Alan Cole, vice president of retirement plan adviser services and wealth at OneDigital, 403(b) plans participation rates “[increased] across the board.”

“Most 403(b) plan sponsors are taking a look at education and advice within the plan,” Cole adds, “which also was driving better engagement.”

The addition of auto-enrollment is one way nonprofit retirement plans are evolving to be more similar to 401(k)s, explains Wood. Incorporating active choice and other behavioral finance learnings has meant that “how we drive people to the best action has incrementally gained so much momentum,” Wood says.

“It’s like [innings of] a baseball game” as each type of plan continues to evolve, says Wood: “The 401(k) market is in the ninth inning of being commoditized [and] understanding what a fiduciary [is]; health care is in the seventh inning [as] mostly consolidated; higher education [retirement plans are] in the fifth inning; [and] K through 12 [plans are] in the second inning, in terms of development.”

Participation Is the Start, Not the Goal

Increasing participation rates for 403(b) plans is only the beginning of a longer journey, Cochrane notes. Employers must support nonprofit workers to save, accumulate the greatest possible pool of assets and maximize their retirement security to safeguard against the risk of outliving their money in retirement, she adds.

“Get employees in the business of saving for their longest period of unemployment,” Cochrane says.

Nonprofit sponsors are increasingly using auto-enrollment with higher default rates and automatically increasing those default rates over time, PSCA data show. Using auto-escalate with re-enrollment can assist participants save greater amounts, Cole says.

In 2022, more than one-third (36.1%) of plans with auto-enrollment used a default rate greater than 3%, up from 26.9% in 2021, and two-thirds of plans automatically escalated the default percentage, up from 57% in 2021, according to PSCA. With auto-escalation, participants’ contribution from salary will increase by a specific rate, usually 1%, each year unless they choose otherwise.

For sponsors, using re-enrollment is a tool “capturing participants in the plan who were not enrolled; perhaps they didn’t understand it enough [at the time they were hired],” Cole explains.

Sponsors are also increasing immediate eligibility to receive employer contributions, adding Roth options and applying investment policy statements, according to PSCA.

Nearly half of plans (47.8%) allowed participants to receive matching employer contributions immediately upon hire in 2022, up from 36.3% in 2021; two-thirds offered Roth options, up from 58.8% in 2021; and 63.3% of organizations included an investment policy statement in plans, up from 61.2% in 2021 and 25% in 2013.

For Cochrane, the crucial task facing 403(b) plans is driving participants toward saving more, emphasizing—for employees who can afford to—the significance of retirement savings in small amounts.

“Our next big challenge is getting [participants to increase their retirement savings] from whatever they’re doing right now to [what] … they’ll need for retirement,” she says. “There’s a lot of struggle happening financially in the nonprofit sector to do all of the great things they want to do. And that is a big challenge for HR teams and nonprofit employers nowadays.”

Cochrane explains, “Individual outreach is the only way we’re going to get there as an as a nation or as an industry. One-on-one consultation has been the single best success we have found with helping every employee.”

For 403(b) plans, the average savings rates in plans with Fidelity Investments as the recordkeeper reached 11.5% in the fourth quarter of 2023, up slightly from 11.1% in Q4 2018. In the same period, the total savings rates in 401(k) plans reached 13.9%, up from 13.1% in 2018, according to data sent by Hub International.

Education and Communications

Personalizing retirement plan education to help boost savings requires sponsors to emphasize the importance of saving for their long-term retirement readiness, Cochrane says.

“[Sponsors] need to take a very parental overview [of] education with employees to say, ‘Do you have the ability to put $25 in today out of every paycheck?’” she says.

Providing education can mean starting at the basics of investing and retirement plans: explaining what a target-date fund is; what TDF vintages are; how to pick appropriate TDF vintages for their age; how the plan’s qualified default investment alternative works; and what a glide path is, according to OneDigital’s Cole.

Explaining how to properly use retirement plans is not unique to 403(b) plans, he adds. Yet, for developing an education strategy, tailoring aspects to the demographics of sponsors is useful, Cole says.

“When I’m working on a [retirement plan of a] college and university, they’re typically very focused on education, so when developing their education strategy, it resonates with the employee, [and] they’re able to understand, ‘I’m here to learn; I teach,’” Cole adds. “[Retirement plan education] is more impactful in that environment. If you have a foundation, that may or may not resonate with everyone.”

When developing an education strategy, sponsors can study their employee population’s level of engagement with the plan’s recordkeeper or adviser, adds Cole.

Greater personalization reflects that “plan sponsors are much more attuned to their employees’ need to figure out where my next best dollar goes,” Wood adds, and for 403(b) plan sponsors with employees in health care and education, student loan debt is another barrier.

“If you think [through] the eyes of a nurse or a teacher—especially those under the age of 30—the challenge [to increase retirement contributions] has been a lot of student loan debt,” Wood says.

For plan participants dealing with student loan debt, personalizing education means forming a financial plan with the participant in which their priority is to pay off loans before contributing to the retirement plan, he explains.

Key strategies to boost other participants’ contributions include preparing to make decisions about health care, using a health savings account and student loan debt, Wood says. Sponsors with high-deductible health plans, which can be paired with HSAs, must communicate the availability of this option and how it works, he adds. Communication must also convey information deliberately but use a more engaging approach.

“In the [old] days, you’d have advisers sitting up in front of a room, and they would preach to employees or almost dictate, ‘You must save for retirement. You can’t afford not to,’ it was a different way of communicating,” Cochrane says. “Now we realize [a better approach is] more maternalistic or paternalistic.”

Sponsor education and communication should “encourage employees to sign up for this free-to-them retirement benefit, offering this guidance that’s not intimidating [and] it’s not a sales pitch,” Cochrane adds. “No one’s going to talk down to them or make them feel bad about anything, but encourage those employees” to get engaged with their retirement plan.

Pay Gaps

Nonprofit participants face different challenges than many corporate employees that can limit their saving: a trend toward lower salaries. OneDigital’s Cole explains low pay is an issue in both types of plans, as workers of all kinds face low compensation and high costs of living.

Insufficient retirement savings is “not specific to 403(b) [plan participants because of low salary, [because] even in [a] 401(k), if you’re [a low-paid worker] in a call center, you’re likely not to have contributed to your 401(k) plan,” he says. “If you’re an employee making $20,000 a year [or between] $25,000 and $30,000, you’re going to have a hard time saving in a retirement account. 403(b) or 401(k) doesn’t matter.”

Cochrane notes that nonprofits in social services, particularly, struggle to provide robust retirement benefits or offer a retirement plan. Lacking employer-sponsored retirement benefits reduces the retirement readiness of workers at nonprofits, many of whom are from historically “marginalized” backgrounds, Cochrane says.

“A social welfare organization that is feeding the poor on tight budgets, they are more apt to not have a retirement plan or, if they do, they do not necessarily have the funds to encourage [contributions]” or have employer matching contributions, she explains.

In PEPs, Attaining Economy of Scale Is Critical, Sometimes Illusive

While the pooled plan providers, sponsors of multiple employer plans, continue to see asset inflows, for sponsors, joining a PEP to realize cost savings can be more difficult than advertised.
In PEPs, Attaining Economy of Scale Is Critical, Sometimes Illusive

Retirement plans that include multiple employers have continued to grow in assets, but the growth of assets necessary to reach the critical size where economies of scale can be achieved may take years. The  forecasted cost savings to plan sponsors of joining a pooled employer plan over using a single employer plan may not materialize, depending on the sponsor’s pooled plan provider.

Pooled employer plans were created by the Setting Every Community Up for Retirement Enhancement Act of 2019 and came into effect in January 2021 to provide an alternative for sponsors to a single-employer plan and are a less restrictive subgroup of multiple employer plans.

Expanding MEPs to create PEPs was billed as a cost-efficient and less burdensome way for employers to provide a retirement plan, moving the needle to narrow the retirement coverage gap.  

“If you can get the economy of scale where you’re running your PEP efficiently, you can drive costs down,” says Kevin Gaston, director of plan design and institutional consulting at Vestwell. Gaston claims, single-plan sponsors “don’t ever get that scale.”  

Large plans not only have lower average costsper participant but the range of costs across plans is also lower, finds the Investment Company Institute and Brightscope.   

Vestwell is registered with the DOL to offer MEPs, including PEPs. Vestwell representatives did not disclose its assets in MEPs. 

Pooled plan providers must register with the Department of Labor and to date 149 have launched, according to the latest data shows. Among registered PPPs, 121 have at least one registered PEP and 427 total PEPs have registered with the regulator, says Robb Smith, president of RS Fiduciary Solutions, PEP-HUB and PEP-RFP. His company tracks PEP registration on the DOL’s EFAST website with the latest data.

PEPs and Retirement Coverage

Joining a PEP allows a group of participating retirement plan sponsors to join a single plan administered by a pooled plan provider, which becomes the named fiduciary responsible for performing most administrative functions for the plan.

For sponsors, joining a PEP “is less work, less risk and better outcomes…due to the economies of scale and the cost savings and we’ve seen that play out,” explains Rick Jones, a senior partner at Aon and head of its wealth solutions division.

“The cost savings that we can drive through the economies of scale and the purchasing power that Aon has in the markets generally means that more money stays in participants accounts rather than being paid in fees and grows for retirement,” explains Jones. “Different employers are attracted to different degrees to all three of those depending on where they’re coming from but they are finding that they’re having to do a lot less work to provide a customized and comprehensive 401(k) program.”

Aon plc is a registered PPP and sponsors a PEP. Aon partnered with Voya to provide recordkeeping services to support PEP sponsors. Aon’s PEP comprised nearly 80 employers, 70,000 eligible employees and $2.3 billion in participant retirement assets, as of the most recent data from Aon.

Aon’s PEP is available to sponsors with 100 employees or more.

Voya serves as a recordkeeper for approximately $90 billion overall in assets within its multiple employer solutions book of business, explains Ginger Brennan, head of multiple employer solutions at Voya.

Effect to Small Businesses

For PEP-participating sponsors, the economies of scale are critical to them realizing cost savings. And the savings are not a given.

At Aon “we were able to offer the buying power and the economies of scale that Aon investments had more broadly, on day one when we launched: Not every organization can do that or say that” Jones adds.

Cost savings may take some time to materialize as new PEPs must reach a significant size, the Center for Retirement Research at Boston College research notes.


Considering Costs of Single Employer Plans vs. PEPs

Plan sponsors considering a pooled employer plan will likely be factoring in the cost comparisons to a single employer plan.

Boston College researchers provided this breakdown of the fees that should be considered:

  • Set-up fees: one-time costs to set up a plan. Single-employer plans may have higher set-up fees if employers want a highly customized plan;
  • Administrative fees: The burden of administrative fees depends on how fees are structured and the level of plan assets. Fees based on a percentage of assets will be limited when plans are new and assets are low. In contrast, flat administrative fees can be burdensome for participants in new plans. However, as plan assets grow over time, flat fees will represent a smaller share of plan assets;
  • Investment fees: Expense ratios for the same mutual fund can differ dramatically, depending on the share class. A recent Pew study found that the expense ratio of a mid-cap fund ranged from 0.75% to 1.45%, varying by share class. Lower-priced share classes are offered to investors with more assets, so small pooled plan providers may not be able to offer the lowest fees on investment ; and
  • Audit fees: Employers with less than 100 participants are not required to conduct an audit if they have a single employer plan. Small employers in a PEP are subject to an audit if the PEP has more than 1,000 participants, but these costs will be shared by all employers in the PEP.

For small businesses, joining a PEP means paying a portion of Department of Labor audit fees, which could be an added cost. For a small employer, the auditing fee “wouldn’t be a deal breaker, but it would just be an additional consideration,” says Barry Salkin, a counsel at the Wagner Law Group.

When it comes to cost by plan size, the “401k Averages Book” provides this breakdown for a single employer plan:

  • For sponsors with a $10,000 plan average account balance, the total average plan cost of bundled investment, recordkeeping and administration as a percentage of assets is 4.16%;
  • For sponsors with a $50,000 average account balance, the total average plan cost as a percentage of assets is 1.84%; and
  • For plans with a $100,000 average account balance, the total average plan cost as a percentage of assets is 1.43%.


Small employers with fewer than 100 employees account for the majority of U.S. businesses and 35% of private sector workers, according to the Bureau of Labor Statistics. About half of small employers offer a retirement plan, compared to about 90% of employers with more than 100 workers, finds the Center for Retirement Research.  

Surveys of small employers show that the two top reasons small firms do not offer a retirement plan are revenue concerns and administrative burden, found the Center for Retirement Research. Some firms may be too small or too new to offer a retirement plan. Among companies that are established enough but may be concerned about costs and administrative burden, PEPs may be able to help, wrote Anqi Chen and Alicia Munnell, authors of the Center for Retirement Research January 2024 report, A Multiple Employer Plans Primer: Exploring Their Potential to Close the Coverage Gap.

But the plans have not had enormous success. 

And efforts alongside SECURE 2.0 and prior to it outside of PEPs, which have aimed to facilitate small business to provide retirement plans have not shown great success, either.

Small business were largely unaware of tax credits available to small employers as a result of SECURE 2.0, finds a survey published by the Employe Benefit Retirement Institute, earlier this year and 24% of employers surveyed in 2022 by ShareBuilder 401k believed 401(k) plans were too costly for their businesses. As a result of lawmakers in Colorado and Oregon passing state auto-IRA mandates, more small business in those states have started to offer 401(k) plans, according to research published in December. 

PEP: Buyer Beware

Key to the success of Aon’s PEP was the company’s ability to take advantage of the size of its overall business — and assets under management — outside the PEP, adds Rick Jones.

“We launched with zero and the first couple entrants were smaller and had millions of dollars as opposed to 10s of millions or hundreds of million dollars of 401(k) assets,” says Jones. “At that point, we were leveraging the purchasing power of Aon investments and we were able to go to leading investment managers and say we’re putting together this PEP help us to devise an investment lineup at costs that are incredibly market competitive and they did just that.”

For sponsors with fewer than 100 employees to achieve lower fees, attain the in a PEP they must select the right PPP provider, Jones says.

“We find that when we price things out and do a side-by-side benchmarking that we generate and are projected to generate cost savings 90% plus of the time,” Jones says. “We are also using the purchasing power of Aon investments and the trillions of dollars of assets under advisement that we have in-house already and the hundreds of billions of dollars of assets under management [at Aon}. We find that the benchmark fees for investment options in [the] Aon PEP are 50%, lower than the benchmarks in the broader industry, again, because of the purchasing power we can offer.”

USI Consulting Group works with sponsors, consulting on their retirement plans to find the appropriate fit.

A USI Consulting Group sponsor client with about $20 million in plan assets joined a PEP but were unhappy. They moved to a single plan and realized cost savings, he explains.

“The fees decreased by about 66% or so, because they were, frankly, a bit too big to be participating in the PEP that they had joined, prior to our engagement with this client,” he says.

For sponsors, joining a PEP can add value in cost savings for “both recordkeeping and administrative services,” but not for every sponsor, he adds.

But sponsors have concerns, about restrictive plan designs and inflexibility in a pooled plan.  

Sponsors joining a PEP are “using a plan document that does not allow for the same level of customization as you can achieve in an individually designed plan document or prototype plan document,” says Lamendola. “For a lot of plan sponsors, that might be okay: They might be looking for something that’s a little bit more vanilla, they’re not looking for something that has much complexity, but many plan sponsors are looking for more flexibility than they can achieve in a PEP and therefore they’re employer route.”

“Depending on the size of a plan that is moving into a PEP or MEP, savings can potentially be realized by remaining as a stand-alone plan—even when taking additional audit fees into account.”

Preset investment lineups can exemplify the experience of sponsors joining a PEP, says Vestwell’s Gaston.

For sponsors PEPS [are] “like using [the meal-prep delivery service] HelloFresh, [because] everything comes to your door, everything’s already exactly what you need and that’s great for a lot of sponsors,” he says. “On the flip side, the more you need your individual things—maybe you have allergies, maybe you have choices that are different—then [sponsors may] start looking towards whether you’re going to be a single employer plan.”

Eric Droblyen, CEO and president of Employee Fiduciary, a third-party administrator, says the firm does not “get a lot of interest from employers,” in joining PEPs.

“Nobody’s saying, ‘Hey, I’d love to pool my assets with a bunch of other small employers, but we have advisers that that will ask,” he says. [For sponsors], it made sense 15 or 20 years ago, when plans needed lots of assets to access low-cost investments, but index funds have made that whole argument moot.”
