A 25-year-old earning $50,000 is now putting roughly $3,100 a year into a retirement account. That figure, on its own, is easy to dismiss. But it represents something no other generation in the American workforce can claim right now: a contribution rate that is still going up.
Gen Z raised its average 401(k) deferral to 6.2% of pay in 2024, according to a 2025 workforce trends report from Dayforce, which analyzed payroll data from more than 1.2 million U.S. employees. Baby boomers dropped to 7.1%. Gen X fell to 7.4%. Millennials slipped to 6.8%. All three generations had been steadily increasing their contributions since 2021, a three-year streak that is now broken. Gen Z is the only cohort still climbing.
What the numbers actually look like, generation by generation
The Dayforce data comes from real payroll records, not self-reported surveys. That distinction matters. Survey-based retirement research tends to overstate savings behavior because people report what they intend to do, not what they actually do. Payroll data captures the money that left the paycheck.
Here is the generational snapshot from the most recent data:
- Gen Z (born after 1996): 6.2%, up year over year
- Millennials (born 1981 to 1996): 6.8%, down for the first time since 2021
- Gen X (born 1965 to 1980): 7.4%, down for the first time since 2021
- Baby boomers (born 1946 to 1964): 7.1%, down for the first time since 2021
Gen Z’s rate is the lowest in absolute terms, which makes sense given that workers in their twenties typically earn less. A 6.2% deferral on a $45,000 salary works out to about $2,790 a year. A Gen X worker contributing 7.4% on $85,000 is putting away roughly $6,290. But the trajectory tells a different story.
Starting early matters enormously because of compounding. According to Fidelity’s retirement planning research, a worker who begins saving at 25 and consistently increases their rate can accumulate significantly more by 65 than someone who starts at 35 with a higher initial rate, even assuming identical investment returns. Every year of delay costs more than most people realize.
The federal government keeps raising the ceiling. Most workers are using less of it.
The IRS announced in guidance published in late 2025 that the 401(k) elective deferral ceiling rises to $24,500 for 2026, up from $23,500 the year before. The IRA contribution limit also climbs to $7,500. For workers 50 and older, the catch-up contribution remains $7,500. And under Section 109 of the SECURE 2.0 Act, workers between 60 and 63 can contribute an additional $11,250 on top of the base limit, bringing their maximum possible deferral to $35,750.
These adjustments are pegged to inflation through cost-of-living formulas the IRS recalculates each year. The intent is straightforward: as prices rise, workers should be able to shelter more income from taxes inside retirement accounts.
But the Dayforce data reveals a disconnect. The workers with the most to gain from expanded catch-up provisions, boomers and Gen Xers who are approaching or already inside the catch-up eligibility window, are the same ones reducing their contributions. The gap between what the tax code permits and what workers actually defer appears to be widening for everyone except the youngest savers.
For Gen Z, the $24,500 cap is largely irrelevant right now. At 6.2% of a typical early-career salary, they are nowhere near the ceiling. The limits matter most for high earners and older workers trying to accelerate savings before they stop working. The paradox is that the people those provisions were designed to help are the ones pulling back.
Why older workers are cutting contributions
The Dayforce report does not isolate a single cause for the pullback, but the timing lines up with several financial pressures that have intensified over the past two years.
Many boomers and Gen Xers are in their peak expense years. Mortgage payments, college tuition for children, and health care costs that climb with age all compete for the same dollars that could go into a 401(k). According to the Bureau of Labor Statistics, cumulative inflation since 2020 has pushed consumer prices up by more than 20%, and categories like food, insurance, and medical care have risen even faster. Even modest increases in monthly bills can force trade-offs, and retirement contributions are one of the few line items workers can adjust without immediate consequences.
Millennials, now solidly in their thirties and early forties, face a different but equally binding set of constraints. Home prices remain elevated in most metro areas, according to the S&P CoreLogic Case-Shiller Index, and many in this cohort are still managing student loan balances or trying to build emergency reserves. Raising a 401(k) deferral competes directly with saving for a down payment or paying off debt. The Dayforce figures do not break out these competing priorities, but the aggregate decline suggests that near-term financial stability is winning out over long-term tax-advantaged saving for a meaningful share of this generation.
There is also a psychological dimension. As retirement gets closer, some workers become more reluctant to lock away money they might need in the short term, especially if they feel behind on savings or uncertain about job security. That caution can translate into smaller deferral percentages even when catch-up provisions would allow them to contribute more than ever.
The employer match question
One factor the Dayforce data does not address in detail is the employer match, which is often the single most valuable feature of a 401(k) plan. According to Fidelity, a common employer match structure is 50 cents on the dollar up to 6% of pay, meaning a worker contributing 6% effectively gets an additional 3% from their employer.
Gen Z’s 6.2% average rate is notable in this context because it sits right at or just above the typical match threshold. Whether by design or coincidence, these workers appear to be capturing most or all of the free money their employers offer. Workers who reduce their contributions below the match threshold, by contrast, leave compensation on the table. The Dayforce report does not specify how many workers who pulled back dropped below their employer’s match ceiling, but even a small reduction could mean forfeiting hundreds or thousands of dollars a year in employer contributions.
For younger workers, automatic enrollment features increasingly set default contribution rates at or near the match threshold, which may partly explain why Gen Z’s rate lands where it does. Older workers who joined their companies before auto-enrollment became widespread may have set their rates manually years ago and never adjusted them upward, making a downward revision during a tight financial stretch more likely.
Whether Gen Z can sustain the momentum
The optimistic case for Gen Z rests on two structural advantages: time and defaults. Starting at 6.2% in their twenties gives them decades for compound returns to build. And if their employers pair automatic enrollment with automatic escalation, meaning the deferral rate ticks up by a percentage point each year unless the worker opts out, the default path is to save progressively more without making repeated active decisions.
The risk is that Gen Z eventually runs into the same pressures now weighing on older cohorts. Housing costs, family expenses, and debt can erode savings discipline at any age. Workers who feel financially stretched tend to reduce or pause contributions, and once that pattern starts, restarting can be difficult. The three-year upward trend among boomers, Gen X, and millennials looked durable until it wasn’t.
Persistent inflation, volatile markets, or prolonged wage stagnation could all test Gen Z’s willingness to keep raising their rates. The Dayforce data captures a single period. Future updates will show whether this generation’s early lead holds or fades as life gets more expensive.
Who the retirement system actually works for
The combination of rising IRS limits and falling contribution rates among most workers points to a structural tension in the U.S. retirement system. Higher caps primarily benefit people who are already saving aggressively and earning enough to approach the ceiling. For workers cutting back because of monthly cash-flow pressure, a higher limit changes nothing. Their binding constraint is not the tax code but the cost of rent, groceries, child care, and debt payments.
Automatic enrollment and default escalation have proven far more effective at lifting participation than raising statutory limits. Vanguard’s 2024 How America Saves report found that plans with auto-enrollment features see participation rates above 90%, compared with roughly 66% for plans that rely on voluntary sign-up. The policy implication is clear: plan design matters more than plan generosity for the workers who need the most help.
For anyone reading the generational comparison, the takeaway is less about competition and more about trajectory. Gen Z’s 6.2% rate shows what is possible when saving starts early and is woven into the paycheck from day one. The pullback among boomers, Gen X, and millennials shows how quickly that progress can stall when economic conditions tighten. The federal framework now allows more tax-advantaged saving than at any point in the 401(k) program’s 47-year history. Whether workers across every generation can actually afford to use that space is the question no contribution limit increase has answered.
