Auto-Enrollment & Auto-Escalation: A Case Study in Thoughtful Plan Design
For many plan sponsors, the question is no longer whether to implement automatic features, it’s how to do it well.
With the continued evolution of legislation like SECURE 2.0 and a growing focus on participant outcomes, auto-enrollment and auto-escalation have become foundational plan design tools. But like any powerful tool, their impact depends on how thoughtfully they’re implemented.
This is where thoughtful plan design and participant guidance come together.
Let’s walk through a real-world case study, followed by a balanced look at the pros, tradeoffs, and what the research tells us.
Case Study: Turning Inertia into Progress
Employer Profile:
Mid-sized manufacturing firm (250 employees)
Plan Design (Before):
• Voluntary enrollment (opt-in)
• Participation rate: 62%
• Average deferral rate: 5.1%
Plan Design (After Enhancements):
• Auto-enrollment at 6% default
• Auto-escalation of 1% annually up to 10%
• Default investment: target date solution
• Re-enrollment campaign with education
Results After 18 Months:
• Participation increased to 91%
• Average deferral rate increased to 7.8%
• Meaningful increase in employer match utilization
What changed?
Not the intent of employees but rather the structure around their decisions.
Auto features didn’t create new motivation, they removed friction.
Why It Works: The Behavioral Advantage
At the core of automatic features is a simple insight:
Most employees intend to save but don’t act.
Research shows:
• 68% of employees say they should save more
• Only ~3% actually follow through without intervention (NBER)
Auto-enrollment flips the default. Instead of requiring action to participate, it requires action not to. That shift alone can dramatically improve outcomes.
The Pros: Where Automatic Features Shine
1. Increased Participation
Auto-enrollment consistently drives participation rates above 85–90% in many plans (BDO)
This is especially impactful for:
• Younger employees
• Lower-income workers
• First-time savers
2. Improved Savings Behavior Over Time
Auto-escalation helps participants gradually increase contributions without feeling it all at once.
It aligns saving with:
• Pay increases
• Career progression
• Behavioral comfort
3. Better Alignment with Retirement Outcomes
When auto-enrollment and escalation are combined, success rates (adequate retirement income) can increase dramatically.
One study showed improvement from:
~46% probability of success → ~79% when multiple plan design features were applied (PubMed)
That’s the difference between “participating” and “on track.”
4. Stronger Employer Value Proposition
Automatic features:
• Simplify decision-making
• Increase perceived benefit value
• Demonstrate employer commitment to financial well-being
The Tradeoffs: Where Sponsors Need to Be Intentional
Automatic features are powerful, but they are not perfect.
1. Default Rates Can Become Anchors
Employees often stay at the default.
A 3–6% default may:
• Improve participation
• But unintentionally cap savings behavior
2. Cash Flow Sensitivity
Some employees, especially lower-income, may opt out due to immediate budget pressure.
Design matters:
• Too high → opt-outs increase
• Too low → savings fall short
3. Leakage Still Undermines Outcomes
Even with strong plan design, participant behavior outside the plan matters.
Research shows:
• Cash-outs at job change significantly reduce long-term impact (CNBC)
• A meaningful portion of balances are withdrawn during transitions
Auto features help, but they don’t solve everything.
4. Escalation Opt-Out Behavior
Auto-escalation participation tends to decline over time as participants opt out of increases.
This highlights a key reality:
Automation gets people started, but engagement sustains progress.
What the Research Really Says
There’s a tendency to think of auto features as a silver bullet. The data tells a more nuanced story:
What’s clearly true:
• Participation increases materially
• Savings rates improve
• Outcomes are better than opt-in designs
What’s also true:
• The impact is positive. But more modest than originally expected (CNBC)
• Human behavior (opt-outs, job changes, cash-outs) reduces long-term effectiveness
In other words:
Plan design drives momentum. But participant behavior determines outcomes.
Where Plan Sponsors Can Elevate the Outcome
The most effective plans don’t just implement auto features, they integrate them into a broader strategy:
1. Start with the Right Defaults
• 6%+ enrollment baseline
• Escalation toward 10–12%
2. Pair Automation with Communication
• “Why it matters” messaging
• Annual check-in prompts
• Clear visibility into employer match
3. Address Leakage
• Rollover education
• Portability solutions
• Terminated participant outreach
4. Re-enroll and Reset When Needed
Periodic re-enrollment can realign participants with stronger defaults.
Final Thought
Auto-enrollment and auto-escalation are not just plan features, they’re behavioral design tools.
When implemented thoughtfully, they:
• Remove friction
• Create momentum
• Improve outcomes at scale
But the real value emerges when automation is paired with guidance.
Because the goal isn’t just participation.
It’s progress.
