Retirement planning used to feel simpler. You saved, you invested in a balanced portfolio, you collected Social Security at 65, and things more or less worked out. That picture has grown considerably more complicated over the past few years, and economists are paying attention. The assumptions baked into a lot of conventional retirement wisdom were shaped by decades of low inflation, falling interest rates, stable pensions, and shorter life spans – conditions that no longer reliably describe the world people are actually retiring into.
With 2035 less than a decade away, the stakes are real for millions of people currently in their peak earning and saving years. Some of the strategies that feel most reassuring are precisely the ones drawing the most scrutiny from researchers and financial economists. Here are eight of them worth reconsidering.
Counting Heavily on Social Security as a Foundation

Social Security remains a foundation for millions of retirees, yet economists warn about long-term funding stress. Longer lifespans and lower birth rates continue to strain the system's balance over time. The deficit has been building for years, and the trust funds that historically covered the gap are under serious pressure.
The Social Security program is mostly funded through the taxes people pay on their income. Unfortunately, it has been running a deficit in recent years, with more retirees weighing on the system than active workers paying into it. The Social Security Administration estimates that the Old-Age and Survivors Insurance fund could be depleted by 2034 if the program continues at its current deficit. This doesn't mean people will stop receiving benefits, but benefit cuts may be necessary to ensure the program can be fully funded by tax revenue. Right now, the potential cuts could reach roughly a quarter of current benefit levels.
Treating the Classic 60/40 Portfolio as a Set-It-and-Forget-It Solution

The 60/40 portfolio allocates 60% to equities for growth and 40% to bonds for stability and income. The strategy works because stocks and bonds historically move in opposite directions – when stocks fall, bonds tend to rise, cushioning portfolio losses. For decades, this inverse relationship made the 60/40 a reliable workhorse. That reliability cracked in 2022.
The 60/40 portfolio saw a significant drop of approximately 17% in 2022, its worst calendar-year performance in decades. What made the decline unusual wasn't just its size – it was that stocks and bonds both fell at the same time, undercutting the balance the strategy is known for. While the 60/40 portfolio remains a useful starting point, its effectiveness varies based on personal circumstances and market dynamics. A one-size-fits-all approach is insufficient, and retirees should engage in proactive, customized financial planning.
Relying on the 4% Withdrawal Rule Without Adjustment

For years, financial planners and early retirees alike have relied on the so-called "4% rule" as a guideline. The rule says it's generally safe to withdraw 4% of a balanced portfolio annually, adjusted for inflation, for a 30-year retirement – first described in a 1994 paper by financial advisor Bill Bengen. It's clean, memorable, and widely followed. It's also increasingly viewed as incomplete.
The 4% rule, which Bengen recently revised to 4.7% with additional asset classes, isn't wrong so much as it's incomplete, say researchers. The rule was designed as a worst-case survival rate, not an optimal spending rate – and most retirees aren't living through the worst case. Morningstar's 2025 research found that retirees who experienced poor returns in the first five years and did not adjust their spending were far more likely to go broke. Rigidity, in other words, is its own kind of risk.
Planning to Work Longer as a Retirement Safety Net

As Americans live longer and worry about outlasting their money in retirement, a growing number are counting on working longer for their future financial security. Roughly 70% of U.S. workers who haven't retired yet have considered pushing back their retirement date. Nearly half of those surveyed said they're afraid they won't have enough money to retire. The intention is sound. The execution is where things can fall apart.
According to a report from the Employee Benefit Research Institute, two in 10 workers adjusted their target retirement age in 2024, with most of them now planning to retire later. But experts say that plan to work longer may not be as reliable as workers hope. Others say that perspective doesn't align with how the labor market actually works. Health events, layoffs, and reduced demand for older workers can all accelerate an exit from the workforce on someone else's timeline.
Underbudgeting for Healthcare Costs

The surprise for many retirees isn't that healthcare expenses exist – it's the magnitude of those expenses, and how quickly they can change after a diagnosis, procedure, or new medication. Longer lives mean savings must stretch further, and healthcare costs often rise faster than general inflation. Most pre-retirees substantially underestimate what's coming.
According to the 2025 Fidelity Retiree Health Care Cost Estimate, a 65-year-old individual may need $172,500 in after-tax savings to cover health care expenses in retirement. Fidelity's 2025 estimate also suggests that a retired couple may face over $345,000 in out-of-pocket healthcare costs over the course of retirement. Health care inflation tends to outpace general inflation – from 2000 to mid-2024, medical care prices increased roughly 121% while all items rose around 86%, according to Consumer Price Index data.

Longevity risk is the possibility of outliving your retirement savings – a growing concern as people live longer than ever. Advances in healthcare and lifestyle changes mean many retirees may need their savings to last 30 years or more. This risk is amplified by rising healthcare costs, inflation, and the shift from pensions to 401(k) plans, leaving individuals responsible for managing their own retirement funds.
At just 2% inflation, a traditionally "conservative" portfolio generating 4-5% net returns could deplete 10 to 20 years before the end of a 50-year retirement – potentially leaving retirees without resources for their final decades. The population over 85 is growing rapidly, projected to double within the next 20 years. By 2060, the number of people aged 65 and older will reach 95 million, a sharp rise from 56 million in 2020. This growing wave means many retirees will need their savings to last for 25, 30, or even 35 years.
Depending on a Traditional Pension That May No Longer Exist

For much of the 20th century, the American retirement system relied on what economists call the three-legged stool: Social Security, employer pensions, and personal savings. Social Security has a looming funding shortfall, and another leg of that stool – pensions – has rapidly declined for private sector workers. The numbers tell a stark story of how quickly that leg was sawed off.
In 1989, 63% of full-time workers at companies with more than 100 employees had pensions, according to the Bureau of Labor Statistics. As of early 2023, only about 15% of private industry workers did. Workers now largely depend on 401(k)s and other defined-contribution plans, which rely on them to determine how much to contribute and how to invest those funds. For anyone still mentally factoring in a pension they may not actually receive, this is a critical reality check.
Treating Housing Equity as a Guaranteed Retirement Cushion

Housing costs influence retirement more than many people expect. Rent, property taxes, insurance, and maintenance rarely stay flat. Economists see continued pressure in many regions due to limited supply and population shifts. Owning a home outright feels like security. The math is more nuanced than that.
Retirees who own homes outright may still face rising taxes and repair bills. Those who rent can experience unpredictable increases. Both groups must treat housing as an active expense, not a fixed one. Some older Americans are downsizing or relocating to manage costs. Others tap home equity carefully to support income. Housing decisions are deeply personal, but flexibility can free up cash and reduce long-term financial strain. Treating a paid-off home as a complete financial backstop – without considering what it costs to maintain and remain in – leaves real gaps in a retirement plan.
