Ask four people from four different generations what their retirement plan looks like, and you'll get four completely different answers. One might mention a pension nobody talks about anymore.
Another will shrug and point to a 401(k) that feels perpetually behind schedule. A third might say Roth IRA like it's a personality trait.
The gap between what each generation was promised and what they actually have tells a bigger story about how retirement in America has quietly, and unevenly, transformed over the last sixty years.
Baby Boomers and the pension that still echoes
Boomers came of age when defined benefit pensions were still common, and that legacy shapes how this generation approaches retirement even now. The average 401(k) balance for baby boomers is $260,300 with an average IRA balance of $286,700.
That's the highest balance of any generation, but it's largely a function of time in the market rather than some special savings gene. The real advantage boomers hold is proximity to their peak earning years combined with fewer major expenses weighing them down.
The advantage boomers have is that they are later in their careers and likely to be earning more, and less likely to have major expenses. For those feeling behind, catch-up contributions matter a lot here.
The 401(k) contribution limit for 2026 for individuals is $24,500, but those aged 60 to 63 can make catch-up contributions up to $11,250, for a total of $35,750.
Gen X and the 401(k) experiment gone sideways
Gen X is the generation that got handed the 401(k) as a replacement for the pension, right as the shift was happening, and they're now discovering the fine print. Gen X, the first generation to rely on 401(k)s to build and grow a nest egg, is nearing retirement.
The average Gen X 401(k) balance is $222,100, according to Fidelity Investments' fourth-quarter 2025 analysis, and only Baby Boomers have larger balances at $270,800. The numbers underneath that average tell a more uneven story.
Only 29% of Gen Xers have saved six times or more of their salary, and just 19% have saved eight times or more. Part of the problem traces back to timing.
One reason Gen X is behind in retirement savings is that they got a late start, not beginning until age 32 on average, four years later than Millennials and ten years later than Gen Z. That lost decade of compounding is difficult to make up, even with strong income in their peak earning years.
Millennials and the squeeze between debt and compounding
Millennials occupy an odd middle ground. They started saving earlier than Gen X but are also carrying more competing financial pressure than any generation before them.
For millennials, the challenges when it comes to saving for retirement are likely to be other major expenses taking a big piece of the pie: higher housing costs, student debt, daycare, the list goes on. Still, the balances reflect real progress for a generation that's still years from its prime saving window.
The average 401(k) balance for millennials was $83,700 as of Fidelity's fourth-quarter 2025 data. What stands out is how early many of them actually started.
Research from Nationwide Retirement Institute shows that on average, Gen Z and Millennial savers began contributing to workplace retirement accounts at age 23 and 28, respectively, compared to Gen Xers at age 34 and Boomers at 40. That earlier start, even amid financial strain, gives compounding more runway than it had for the generation before them.
Gen Z and the rise of the Roth first mentality
Gen Z is barely a decade into the workforce, yet their retirement instincts look noticeably different from every generation before them. Gen Z investors have an average 401(k) balance of $18,000 and an average IRA balance of $8,000. The balances are small simply because the timeline is short, not because engagement is low. What sets Gen Z apart is a clear preference for after-tax savings. According to Fidelity data, 21.4% of Gen Z participants now contribute to a Roth 401(k), up from approximately 12% five years ago. The trend extends beyond workplace plans too. Fidelity reported that Gen Z IRA contributions jumped 65% year-over-year in the first quarter of 2026, while two-thirds of all IRA contributions went to Roth accounts. That's a generation making a deliberate bet on future tax rates, not just defaulting into whatever their employer set up.
Where this leaves each generation
Four generations, four very different starting points, and four very different definitions of what "having a plan" even means. Boomers inherited a system built around guaranteed income and are now leaning on decades of compounding to close any remaining gaps.
Gen X got caught in the transition between pensions and 401(k)s, arriving late to a savings habit that assumed an earlier start. Millennials are proving that starting sooner, even under financial strain, still counts for something.
Gen Z, meanwhile, is rewriting the default settings entirely, favoring Roth accounts and showing an early, almost deliberate, engagement with long-term planning that previous generations didn't have at the same age. None of these plans look alike, and that's really the point.
Retirement was never a single system everyone moved through the same way. It's a moving target that each generation has had to hit under completely different rules.
