Gone are the days when turning 65 meant an automatic exit from the workforce. In 2025, the average full retirement age for Social Security recipients has officially risen to nearly 67 for those born in 1960 or later, reflecting a steady upward shift driven by longer life expectancies and financial realities.
With nearly half of Americans aged 60 to 75 planning to work part-time during retirement and 6% expecting to never retire at all, working later in life is becoming a new standard rather than an exception. Here are 10 key reasons explaining this trend.
Longer Life Expectancy Means Longer Working Lives
Americans are living longer than ever before, with the current life expectancy in the U.S. projected to reach approximately 79.4 years in 2025, up from about 68.1 years in 1950—a rise of over 16% across 75 years. This steady increase reflects improvements in healthcare, lifestyle, and overall mortality rates.
As people live longer, they require more retirement savings to support extended retirement periods, which encourages many to work longer to maintain financial security throughout their lives.
Rising Full Retirement Age for Social Security
The full Social Security retirement age (FRA) has been gradually increasing due to legislative reforms enacted in 1983. They aimed at reflecting longer life expectancies and maintaining the program’s financial stability. For people born after 1943, the FRA has risen from 65 to between 66 and 67 years old.
Specifically, starting in 2025, individuals born in 1960 or later will have a full retirement age of 67. Those born in 1959 will reach their full retirement age (FRA) at 66 years and 10 months. While workers can claim Social Security benefits as early as age 62, doing so results in permanently reduced monthly payments—about 30% less than if they waited until their full retirement age.
This reduction incentivizes many to delay retirement to maximize their benefits. Additionally, delaying benefits past the FRA can increase monthly payments by about 8% per year up to age 70, further encouraging later retirement.
Financial Necessity Due to Inadequate Savings
The average retirement savings per household in the U.S. is approximately $114,435; however, this figure varies widely by state and income level, with many households having saved far less than the amount needed to maintain their lifestyle in retirement.
Northwestern Mutual’s 2025 study found that the “magic number” Americans believe they need to retire comfortably is $1.26 million, down from $1.46 million the previous year, yet most have saved far less. For example, the average 401(k) balance is around $110,000, and median IRA balances hover near $35,000, highlighting a large gap between expectations and reality.
About 40% of Americans report having no retirement savings at all, and 25% have less than $10,000 saved. Inflation and rising living costs have made things worse, leading approximately 40% of older Americans to delay retirement to rebuild savings and ensure financial stability.
Healthcare Access Before Medicare Eligibility
Medicare eligibility begins at age 65 for most Americans, marking the start of access to federal health insurance coverage. However, many workers choose to delay retirement until they qualify for Medicare. This is to help them maintain their employer-sponsored health insurance, which often provides more comprehensive coverage or lower out-of-pocket costs than private insurance options available before age 65.
This delay helps them avoid the high costs and limited coverage of private health insurance plans, which can be prohibitively expensive for older adults not yet eligible for Medicare. As a result, the need to retain employer health benefits until Medicare kicks in at 65 is a significant factor causing many Americans to postpone retirement.
Shift from Defined-Benefit to Defined-Contribution Plans
From 1980 to 2008, the share of U.S. workers covered by pension plans dropped from 38% to 20%, while coverage by defined-contribution plans increased from 8% to 31%. This transition means workers must actively manage their retirement savings, including how much to contribute, how to invest, and when to withdraw funds.
Unlike pensions, which provide a guaranteed income for life, 401(k) balances depend on individual contributions and market performance, which can be volatile. For example, the average 401(k) balance dropped 20.5% in 2022 to about $103,900, reflecting market downturns and causing anxiety about retirement readiness.
Despite this, many Americans continue contributing, with pre-retirement baby boomers saving about 16.5% of their income.
Record Number of Americans Reaching Retirement Age
In 2025, a historic peak will occur as approximately 4.18 million Americans turn 65—the highest number ever recorded in a single year. This milestone marks the absolute peak of what is known as “America’s Peak 65® Zone,” a four-year period spanning from 2024 through 2027, during which more than 11,400 people turn 65 every day on average.
The sheer volume of retirees affects Social Security and Medicare systems, workforce participation rates, and the overall economy. Many in this Peak 65 cohort face financial insecurity, with studies showing that two-thirds have assets of $500,000 or less and may rely heavily on Social Security, which typically replaces about 40% of pre-retirement income.
Higher Retirement Ages Among College-Educated Workers
Research shows that older workers with a four-year college degree or higher are increasingly common in the workforce; as of 2023, about 44% of workers aged 65 and older hold a bachelor’s degree or more, compared to just 18% in 1987. This group tends to have jobs with less physical strain, higher pay, and better working conditions, making it easier to continue working past traditional retirement ages.
Moreover, college graduates live substantially longer and healthier lives—on average, about 11 years longer than those without a high school diploma—enabling them to remain capable of work for extended periods.
Studies also indicate that working life expectancy has improved for highly educated individuals, while it has stagnated or declined for those with less education. For example, retirement rates for adults aged 55 to 64 with a college degree have decreased, reflecting their greater likelihood of delaying retirement compared to less-educated peers.
Changing Social Norms and Attitudes Toward Retirement
A 2025 Pew Research Center survey found that most Americans say the best age to retire is around 62, with about 26% preferring to retire between 65 and 69 and roughly a third believing there is no single “best” retirement age. However, financial pressures, healthcare costs, and delayed access to full Social Security benefits often push actual retirement later.
Nearly half of Americans aged 60 to 75 expect to work part-time during retirement, reflecting a shift toward phased or partial retirement rather than a full stop. Additionally, about 19% of Americans aged 65 and older were still employed in 2023, indicating that many continue working beyond traditional retirement ages.
While some report retiring earlier than planned due to unforeseen circumstances, a growing share of workers plan to retire at age 70 or beyond.
Economic Uncertainty and Market Volatility
The Social Security Trust Fund is projected to be depleted by 2033, after which it will only be able to pay about 79% of scheduled benefits, unless, of course, Congress acts to shore up funding. This looming shortfall has raised fears of potential benefit cuts averaging around 20-33%, depending on policy decisions, which adds to retirees’ financial anxieties.
Additionally, economic recessions reduce the number of working contributors to Social Security, further straining the system. For example, over a two-year span starting in December 2007 (during the Great Recession, which lasted from December 2007 to June 2009), total employment dropped by approximately 8.6 million jobs, nearly a 6% decline.
Market volatility also impacts retirement accounts like 401(k)s, causing many near-retirees to delay retirement to recover losses and increase their savings.
Policy Trends and Potential Future Changes
While the full Social Security retirement age has already increased from 65 to 67 for those born in 1960 or later, several policy discussions and proposals suggest raising it further to age 70. Similarly, although Medicare eligibility currently begins at 65 and is not scheduled to increase under current law, some proposals have considered raising the Medicare eligibility age in step with Social Security’s retirement age to reduce program costs.
A 2000 study by the Social Security Bulletin examined hypothetical scenarios where both the normal retirement and Medicare eligibility ages rise to 67 by 2022 or to 70 by 2040. It projected that raising these ages would reduce Medicare enrollment and expenditures but also increase labor force participation among older adults, as many would need to work longer to maintain health coverage and income.
For example, raising the Medicare eligibility age to 67 could reduce Medicare enrollment by 7% and expenditures by 3% by 2030, while increasing it to 70 could reduce enrollment by 20% and expenditures by 11% relative to current projections.
