Access to traditional pensions in the private sector has collapsed to a fraction of what it once was. According to the U.S. Bureau of Labor Statistics, only 14 percent of private-sector workers have access to a traditional defined benefit pension plan as of March 2025—down from 15 percent just one year earlier. The figure cited in the title, 12 percent, appears to reflect older data or a slightly different measurement; either way, the reality is stark: fewer than one in six private-sector workers can count on a guaranteed monthly income in retirement backed by their employer. This marks a dramatic reversal from just three decades ago, when 35 percent of private-sector workers had pension coverage. The shift happened gradually, almost invisibly, as companies abandoned the traditional pension model in favor of 401(k) plans and other defined contribution retirement accounts.
While 72 percent of private-sector workers do have access to some form of employer-sponsored retirement plan, the overwhelming majority of those are 401(k)s or similar plans that shift investment risk and responsibility entirely onto workers. For millions of Americans, this transition means trading a predictable pension check for an uncertain retirement savings account, with no guaranteed outcome. Consider the case of a manufacturing worker with twenty years at the same company in the 1990s versus today. That worker in the 1990s would very likely have a traditional pension waiting at retirement—a monthly income that would arrive reliably for life, regardless of market conditions. A comparable worker today, if the employer even offers a retirement plan, typically receives a 401(k) match and is expected to manage their own investments, bear the market risk, and determine when and how to convert savings into retirement income. The burden of retirement planning has shifted entirely.

Why Did Private-Sector Pension Access Collapse?
The shift away from traditional pensions didn’t happen by accident. It was driven by multiple forces: rising corporate costs of pension obligations, the emergence of the 401(k) as an alternative in the 1980s, companies’ desire to shed long-term liabilities, and pressure from shareholders to boost short-term profits. Each individual company decision—to freeze pensions, to stop enrolling new workers in pension plans, or to switch entirely to 401(k) matches—seemed logical from a business perspective. In aggregate, these decisions dismantled the system that had provided retirement security for millions of American workers. The cost pressure was real. Companies funding traditional pensions carry ongoing liabilities on their balance sheets. When market returns dip or life expectancy increases, the gap between what companies have set aside and what they owe widens.
A 401(k), by contrast, is a defined contribution: the company makes a contribution, and then the obligation ends. For employers, it’s an attractive trade. For workers, it’s a fundamentally different contract: instead of a promise of retirement income, they get a contribution and a hope that their own investment decisions will work out. The pension decline has been accelerating rather than stabilizing. Even in industries where pensions were common—manufacturing, transportation, utilities—companies have been freezing traditional plans and shifting new hires to 401(k)-only arrangements. This creates a bifurcated workforce: older workers with pension coverage from earlier years, and younger workers entering a 401(k)-only world. The transition period spans decades, which masks the magnitude of what is happening. When today’s workers reach retirement age, the fraction with pension income will be far smaller than the current 14 percent.
The Risks of Replacing Pensions with 401(k)s
The shift from pensions to 401(k)s transferred three major forms of risk from companies to workers: investment risk, longevity risk, and management risk. A traditional pension plan invests pooled assets and guarantees a monthly payment for life, no matter how markets perform. A 401(k) is a personal account: if markets crash near your retirement date, your account value crashes with it. If you live longer than expected, your account can run out of money. If you make poor investment choices, you’ll have fewer savings. These risks, once borne by employers and their professional fund managers, now sit squarely on workers’ shoulders. The evidence of this shift’s consequences is accumulating.
Studies show that the average 401(k) balance at retirement is insufficient for many workers to maintain their pre-retirement standard of living. Many workers lack the financial literacy to manage a 401(k) effectively, resulting in high fees, poor asset allocation, or inadequate contributions. The complexity of investing, the need to roll over accounts when changing jobs, and the choice overload of fund selection create friction and opportunity for costly mistakes. A worker with a traditional pension faces none of these challenges. One concrete limitation of 401(k) plans is the required minimum distribution rules, which force workers to withdraw money from their accounts starting at age 73, whether or not they need it, triggering tax obligations and reducing the account’s longevity. With a pension, you received exactly what you needed each month, tax-deferred growth continued until you needed to spend, and there was no risk of “running out” of money. The 401(k) model, by design, creates complexity and risk that older retirement systems avoided.
Who Still Has Pension Access—And Who Doesn’t
Pension access in the private sector is not evenly distributed. Company size matters enormously. Workers in firms with 500 or more employees have a 90 percent chance of having access to some employer-sponsored retirement plan, and a much higher likelihood that at least some workers have traditional pension options. Workers in firms with fewer than 50 employees face a 55 percent chance of having access to any retirement plan at all. Small business owners and their employees, who represent a significant portion of the private-sector workforce, are far less likely to have traditional pensions or even 401(k) matches. Union membership is the single strongest predictor of pension access. About 64 percent of union workers have access to traditional defined benefit pensions, compared to just 9 percent of non-union workers. This gap reflects collective bargaining agreements that prioritized pension security.
In unionized industries like transportation, utilities, and some manufacturing segments, pensions remain relatively common. In non-unionized sectors, they are increasingly rare. This divide has become one of the most significant factors determining whether a worker can expect a predictable retirement income or must rely entirely on their own savings. Industry also shapes pension availability. Workers in finance, insurance, and government-adjacent sectors have higher pension access rates. A worker in financial activities has a 31 percent chance of pension access—more than double the private-sector average. But this concentration means that the vast majority of private-sector workers—those in retail, hospitality, food service, construction, and other service industries—have effectively zero pension access. For these workers, retirement security depends entirely on their ability to save through a 401(k) or individual retirement account.
401(k)s as the Replacement—And Their Limitations
The 401(k) was originally designed as a supplementary retirement savings vehicle, not a primary pension replacement. It was named for a section of the tax code and was adopted initially by a few companies as an add-on benefit. When companies began using it as a pension replacement in the 1980s and 1990s, it was partly because employers could save money and partly because financial services companies promoted it aggressively. What emerged was a new retirement savings model in which workers were expected to be investors, savers, and financial managers—roles for which most workers had no training. The numbers reveal the gap. The median 401(k) balance for a household headed by someone aged 65 to 74 is around $87,000, which would generate only modest retirement income if converted to an annuity. By contrast, a traditional pension might provide $1,500 to $2,500 per month for life.
For millions of workers, a 401(k) balance of $87,000 is inadequate as a sole retirement resource. When combined with Social Security, it may allow for a modest standard of living, but it leaves little margin for unexpected expenses, health costs, or inflation. Employer 401(k) matches vary widely, creating a regressive system where higher-paid workers often receive larger matches. A worker earning $30,000 per year might receive a 2 percent match ($600), while a worker earning $100,000 might receive a 4 percent or 5 percent match ($4,000 to $5,000). Both need retirement savings, but the system provides less help to those who need it most. Additionally, many workers cannot afford to contribute to a 401(k) after covering basic living expenses, meaning they forfeit the employer match entirely. This limitation means that lower-income workers—those with the least financial cushion in retirement—have the hardest time building adequate 401(k) savings.
The Longevity Risk and the Running-Out-of-Money Problem
A primary limitation of 401(k)s is that they can be depleted. With a pension, the employer or pension fund plan bore the risk that you would live to 90, 95, or beyond; the pension checks came reliably no matter how long you lived. A 401(k) has a finite balance. If you retire at 65 with a $300,000 401(k) balance and live to 92, you could run out of money—a scenario called “longevity risk” in retirement planning literature. This risk did not exist under the traditional pension system. Many workers confronting this reality attempt to solve it by purchasing an annuity, which converts a lump sum into a stream of guaranteed payments for life, much like a pension. But annuity rates are set based on current interest rates and mortality tables. A worker who retires in a low interest rate environment will receive lower lifetime payments.
A worker who waits to purchase an annuity might face higher prices if interest rates have fallen further. Pensions, by contrast, were typically established when the worker was employed, and the obligation was locked in. The pricing advantage went to the worker, not to insurance companies. Another warning about the 401(k) system: investment timing risk. A worker who saves diligently for forty years in a 401(k), only to have a market crash occur in the two to three years before retirement, can see their retirement balance plummet. A teacher with a $500,000 401(k) balance in 2007 saw it shrink to $250,000 during the financial crisis—a timing catastrophe. Pension fund managers also faced this risk, but they could spread losses over multiple years and multiple cohorts of retirees; an individual 401(k) holder cannot. This asymmetry means that 401(k) holders bear much higher sequence-of-returns risk than pension recipients did.
Union Workers and the Remaining Pension Ecosystem
Union workers have largely retained pension access, reflecting the bargaining power of unions to negotiate long-term security. In sectors like transportation, where unions represent a significant portion of the workforce, pension plans remain standard. The example of a union truck driver or unionized auto worker illustrates the difference: these workers, despite the decline in pensions across the private sector, often have access to multiemployer pension plans that provide defined benefits, along with retiree health insurance. Their retirement security is not dependent on stock market performance or personal investment decisions.
However, even union-backed pension plans face challenges. Multiemployer pension plans—which cover workers across multiple union employers in an industry—have faced underfunding, and some have required benefit reductions. The Central States Pension Fund, which covers tens of thousands of Teamsters members, required significant benefit cuts in 2016 after decades of underfunding. This demonstrates that even pension plans backed by union agreements are vulnerable to demographic and investment pressures. For non-union workers, such protections do not exist at all.
The Future of Retirement Security in a Pension-Less Private Sector
The trajectory is set. With only 14 percent of private-sector workers in traditional pension plans, and no significant movement toward expanding pensions, the workforce is increasingly reliant on 401(k)s, Social Security, and personal savings. This shift creates a long-term retirement security challenge: future retirees will have less guaranteed income and more responsibility for managing their own retirement portfolios.
Policy discussions increasingly focus on whether Social Security benefits should be increased, whether automatic 401(k) enrollment should be expanded, or whether workers should be allowed to delay Social Security to receive higher benefits. Some forward-looking employers and policy advocates are exploring alternatives: automatic enrollment in 401(k)s with target-date funds, state-backed portable pension systems, and expanded access to lower-cost retirement plans for small employers. These innovations acknowledge that the 401(k)-based system, as currently structured, is not delivering adequate retirement security for many workers. Whether these efforts will meaningfully shift the landscape remains uncertain, but the urgency is growing as the first generation of workers with primarily 401(k)-based retirement approaches retirement age.
