Millennials and Gen X Are Underestimating How Long Retirement Will Last

Many of us view retirement as a finish line, but the data tells a different story. If you are a Millennial or Gen X professional, there is a chance you are planning for a version of the future that may no longer exist.

Retirement is lasting 30+ years

Images are hypothetical


To better understand this, PensionBee conducted a survey in April 2026 exploring how Millennials and Gen X think about retirement, including how they feel about their current retirement outlook and how long they expect retirement to last once they stop working.

Before we go into the findings, take a moment to see how your own retirement readiness compares.

Retirement is lasting longer than most people plan for

When we picture retirement, we often imagine a relatively short phase of life, typically around 10 to 15 years. In reality, higher life expectancy means retirement can often last 30 years or more.

This isn’t just a fun fact. This gap between expectation and reality dictates:

  • How much you save today
  • How confident you feel about your future
  • Whether you risk running out of funds too soon

When we looked at how Millennials and Gen X think about retirement length, there isn’t a single clear picture. Responses are spread across a range of expectations:

  • Uncertainty: Millennials 26%, Gen X 29% (most common response)
  • 20–29 years: Millennials 24%, Gen X 28%
  • 10–19 years: Millennials 20%, Gen X 20%
  • 30–39 years: Millennials 19%, Gen X 14%
  • Less than 10 years: Millennials 11%, Gen X 10%

Overall, there’s no strong consensus on how long retirement will last. Instead, expectations are split between uncertainty and mid-range timelines, with only a smaller share planning for retirements that stretch beyond 30 years.

For Millennials and Gen X, expectations directly shape saving behavior

What people expect about retirement directly affects how they save, and when that outlook is uncertain or negative, it can become harder to stay consistent with savings.

Survey results show a mixed but cautious outlook. While some Millennials and Gen X feel positive about retirement, most express uncertainty or negative sentiment, with relatively few reporting strong confidence in their financial future.

Overall, responses are widely spread, but the dominant theme suggests there is a lack of certainty rather than clear optimism.

This matters because mindset shapes behavior. When people feel uncertain or lukewarm about their outlook, they’re more likely to delay saving decisions, contribute inconsistently, or avoid engaging with retirement planning altogether.

Step 1: Combine old retirement accounts

With 30 million accounts holding nearly $13 trillion in left-behind retirement assets, it's easy to see why so many Americans feel they are behind. By the end of 2026, PensionBee estimates over 30% of all funded workplace accounts could be dormant, up from 21% in 2012.

Bringing old 401(k)s and workplace plans together into a single IRA helps simplify what you've already saved. It reduces the risk of losing track of accounts and makes it easier to understand your overall retirement position in one place. PensionBee makes it simple to get this done without hassle or unnecessary jargon.

Step 2: Make better use of IRAs

From there, your IRA can become one of the cornerstones of your retirement strategy.

This can include:

  • Contributing consistently within 2026 limits up to $7,500 total across Traditional and Roth IRAs, with an additional $1,100 catch-up contribution if age 50 or older
  • Choosing the right IRA type (Traditional or Roth) based on how you want to manage taxes now versus in retirement
  • For self-employed individuals, using a SEP IRA to contribute up to 25% of eligible income, capped at $72,000 in 2026
  • Using tax strategies like tax refunds to boost retirement savings

Because IRAs are not tied to a single employer, they help maintain continuity in retirement saving even as jobs, income, and careers change over time. Over a 30-year retirement horizon, that consistency becomes increasingly important.

Step 3: Build consistent retirement habits

With accounts organized and a clear IRA strategy in place, the focus shifts to consistency.

When retirement lasts decades, even small gaps in saving behavior can compound over time. Planning can include:

  • Automating monthly contributions
  • Increasing savings gradually over time
  • Adjusting contributions when income changes
  • Avoiding early withdrawals that can reduce long-term growth

This helps turn retirement saving into a steady habit rather than a series of isolated decisions, reducing the risk of falling short over a long retirement period.

Ready to see your full picture?

Across Millennials and Gen X, the issue is not awareness, but execution. Many do not fully account for the fact that retirement can last 30 years or more, and that gap can lead to being underprepared when the time comes. 

Close the gap. PensionBee makes it simple to combine your old retirement accounts into an IRA. Many rollovers can be done automatically, but if yours requires extra attention, our U.S.-based personal account manager is ready to guide you every step of the way. 

Right now, PensionBee is offering a 1% match (terms & conditions apply) on every rollover and contribution into a diversified portfolio with ETFs like SPY and MDY from State Street Investment Management, one of the world’s largest asset managers.
