Key Takeaways
A recent Morningstar Investment Management research paper titled Analyzing the Value of Managed Accounts uses a new model to simulate retirement outcomes and observe how plan design and participant behavior interact over time.
The research paper inspired many questions from readers, which we consider and respond to in this article.
- The research shows that wider adoption of managed accounts could help address the retirement savings gap—though managed accounts alone cannot be a full solution.
Do managed accounts actually move the needle for retirement savers? Or do they just look good on paper? It's a question the industry has debated for years, and one the Center for Retirement & Policy Studies decided to take on directly with our latest research, Analyzing the Value of Managed Accounts.
What makes this research different is the model behind it. DCOM—the Defined Contribution Outcomes Model—simulates retirement outcomes using data from millions of participants across thousands of plans, while accounting for how plan design and participant behavior actually interact over time. That last part is harder than it sounds, and it's something earlier research hasn't been able to do well enough to placate naysayers.
Since the paper came out, we've heard a lot of the same questions. This post is our attempt to answer the most important ones. If you have not read the research yet, we highly recommend you do so. You can find the original publication here.
How is this simulation different than any of the others?
We believe DCOM is a revolutionary model in the retirement space. It’s a statistical model that simulates how changes in policy, plan design, and investor behavior could affect overall retirement outlooks. But what makes it special is that DCOM focuses on detailed participant behavior within defined-contribution plans—a granularity other simulation models have not been able to achieve before. It incorporates detailed DC plan logic and allows for close analysis of how contribution behavior, asset allocation, plan features, and managed account usage interact over time.
DCOM was created to address major gaps in existing DC plan research, which often relies on descriptive comparisons that can’t isolate how factors such as participant behavior or plan design affect retirement outcomes. Unlike traditional approaches that treat participant behavior as fixed across a career-span, DCOM models behavior as responsive to plan design, leading to what we consider a more realistic approach.
To measure the value of managed accounts in a DC plan, for example, DCOM runs two parallel simulations for each participant:
- A baseline scenario in which the participant remains in a target-date fund or a self-directed portfolio.
- An alternate scenario in which the participant adopts a managed account at a 40-basis-point fee.
For each scenario, DCOM projects the participant’s wealth-to-salary ratio (i.e., how much money a participant has saved by retirement relative to what they earn) at age 65 and calculates the percentage change between the managed account scenario and baseline. This approach isolates the effect of managed accounts, while controlling for participant and plan design factors that have previously made other analyses on managed accounts’ effectiveness harder to interpret.
Our analysis found that managed accounts boost retirement outcomes across investor types, with self-directed (DIY) investors seeing the largest gains. Managed accounts increase the median wealth-to-salary ratio at age 65 by 5.9% for TDF investors and by 11.4% for DIY investors. Across all plan participants, adopting managed accounts led to an overall increase of 7.7%.
We also found that the benefits of managed accounts were more pronounced among younger investors and those new to their employer because of their time spent in the service. They have a longer time horizon for the effects of higher savings rates to compound, leading to larger projected differences in wealth at age 65. For the youngest age group, adopting managed accounts led to an increase in median wealth-to-salary ratio at age 65 by 9.9% for TDF investors and more than 22% for DIY investors. Compare that to an increase of 3% and 7.5% respectively in the oldest age group.
How do you know improved outcomes with managed accounts aren’t just a result of selection bias?
A common critique of managed accounts research has to do with the effect of selection bias. Or, in other words, the idea that more motivated, educated, and engaged investors are more likely to adopt managed accounts in the first place.
Our model controls for age, wage, tenure, and plan design (i.e., auto-enrollment, auto-escalation, company match, etc.). This helps to isolate behavioral differences rather than differences in who selects a managed account. Keeping this in mind, the largest gains appear among younger, lower-income, and newer participants who are least likely to already be strong savers. If self-selection were driving the results, we’d expect the opposite.
We won't claim this approach is perfect, but it does meaningfully reduce the bias that has held back earlier studies and gives us a clearer picture of how managed accounts actually influence behavior over time. Plus, this is a topic we plan to explore more in-depth in the near future.
Do managed accounts still add value in well-designed plans with auto-features?
Managed accounts do add value in well-designed plans. And by “well-designed,” we mean plans that include features like auto-enrollment and auto-escalation. To put it simply, automating plan features and adding personalization through a service like managed accounts actually complement each other nicely.
The benefits of managed accounts were seen across all plan types we studied. There were increases in wealth-to-salary ratios for the following:
- Plans that use voluntary enrollment: 6.7% for TDF investors, 11.7% for DIY investors
- Plans that use auto-enrollment without escalation: 11.6% for TDF, 18.5% for DIY
- Plans that use auto-enrollment with auto-escalation: 2.7% for TDF, 7.8% for DIY
But the results still indicate that there’s considerable variability across plan types, depending on plan features, as well as participant demographics. Plans with auto-escalation show smaller gains, which is consistent with higher baseline savings rates. Yet even in those plans, managed accounts continue to provide additional lift by personalizing savings recommendations and portfolios. In fact, even among auto-escalated plans, 92% still showed positive projected improvements for participants who switched to managed accounts from TDFs.
It’s also worth noting that access to managed accounts has increased significantly over the last decade. Today, 45% of plans offer this feature, giving 79% of participants access. Adoption, however, has remained relatively constant for the last five years, with each year indicating that around 7% of eligible participants have enrolled. The gap between managed accounts access and use remains substantial—presenting a meaningful opportunity for more thoughtful plan designs that encourage and incorporate managed accounts usage and participant engagement.
Are you just assuming strong market returns?
The primary driver of improved outcomes in our analysis is savings behavior—specifically that managed accounts users tend to contribute more and sustain higher contribution rates over time.
Asset allocation does play a role too, particularly for self-directed investors. But plans have far more ability to influence how much people save than they do to influence what markets return. That's what makes the savings finding significant; it's something plans can actually act on.
One related question we received was whether a one-time savings increase at enrollment could explain our results. It doesn’t. Savings behavior in DCOM is modeled dynamically over time based on participant characteristics and plan features, not a single moment of change.
Can this research apply to my plan?
A common critique of industry research is that it lacks practical applicability. Broad averages rarely tell sponsors whether a specific plan or population is likely to benefit.
The 41 plan design prototypes serve as a starting point, not a constraint. When we conduct plan-specific analysis, we incorporate actual plan features rather than applying a generic grouping. In practice, we first assess whether an existing prototype closely matches the sponsor’s plan design. If it does not, we can adapt the framework or create a new prototype that reflects the plan’s specific design. The analysis can include building customized age-wage profiles, savings-rate models, and asset-allocation models that reflect the plan’s participant population and observed behavior. The analysis also uses the plan’s actual investment lineup and fund-level fees.
Our research also shows that wider adoption of managed accounts could help address the retirement savings gap—though managed accounts alone cannot be a full solution. The shift from generalized conclusions to plan-specific analysis is where the framework becomes most useful.
A More Grounded Way to Evaluate Personalization
Personalization is becoming central to how defined contribution plans evolve. As a result, the industry needs better tools to evaluate it and see when and where personalization can drive real value. This research doesn’t promise uniform results across all plans or populations. But it does provide a framework grounded in how participants actually behave, which can bring us closer to understanding where managed accounts can improve retirement outcomes the most. Future research will extend the framework into deeper analysis of how managed accounts complements plan design, the effect of QDIA, and much more.

Research on Analyzing the Value of Managed Accounts
The data of more than 3 million participants across thousands of employer-sponsored defined contribution retirement plans was included in Morningstar Investment Management’s study, “Analyzing the Value of Managed Accounts”. Participant data was included based on available information and various filters for those who used a managed account service during the 2024 calendar year. As the data was anonymized, Morningstar Investment Management has no knowledge if the data includes participants who were enrolled in the Morningstar Retirement Manager Managed Accounts service.
In no way should any performance shown be considered indicative or a guarantee of the future performance of an actual participant's portfolio with the same investment option or viewed as a substitute for an investment option recommended to an individual participant. Actual results of an individual participant may differ substantially from the historical performance shown for an investment option and may include an individual participant incurring a loss. Past performance is no guarantee of future results.
Performance returns were calculated using a time weighted, geometrically linked rate of return formula. Returns for periods over one year are annualized.
Morningstar Investment Management does not guarantee that the results of their advice, recommendations, or the objectives of an investment option will be achieved.

A "DIY investor" is defined as an individual that has less than 90% of their portfolio invested in an "allocation" fund (e.g., target-date fund) prior to using the Morningstar Retirement Manager managed accounts service. A "TDF investor" is defined as an individual that has 90% or more of their portfolio invested in an "allocation" fund prior to using the managed accounts service. For the baseline scenario, non-MA investors are classified as a DIY investor if less than 90% of their portfolio was allocated to an "allocation" fund, based on Morningstar asset classification methodology. Otherwise, the investor is deemed a TDF investor. One limitation of this approach is that it may classify some participants with balanced fund holdings as TDF investors. However, given the prevalence of TDFs, we believe this assumption is reasonable for establishing a baseline.
Morningstar Investment Management defines "boost retirement outcomes" as an increase in the median/salary ratio by income level.
This analysis quantifies the impact of managed accounts on retirement wealth using Defined Contribution Outcomes Model ("DCOM") in two different ways. In the baseline scenario, the plan participant is either invested in a TDF or self-directs their investments. In the second scenario, for each plan in the dataset, Morningstar Investment Management simulated on a participant-specific basis whether the participant would be better off at age 65 if they adopted a managed accounts immediately at a cost of 40 basis points per year. Morningstar Investment Management's salary curve methodology is used to estimate both forward- and backward-looking real wages for the plan participants in the analysis. DCOM forecasts assets within the DC account to grow based on stochastic portfolio returns from Morningstar Investment Management’s Time Varying Model. The improvement in projected outcomes is the result of both savings and asset-allocation effects, with higher contribution rates being the primary driver. The impact of a wider dispersion in DIY investor holdings from more standard age-based asset allocations plays a role in the larger boost seen when DIY investors adopt managed accounts.
