When you’re part of a retirement community, whether in person or online, you’ll hear a lot of money advice. Some of it is valuable, especially from people who’ve navigated financial challenges successfully. But the truth is, not all wisdom ages well. Financial markets, tax laws, and retirement landscapes change over time, and tips that made sense decades ago can be harmful today. Unfortunately, these outdated recommendations often circulate unchallenged in retirement groups, leading to costly mistakes.

In this article, we’ll break down six common pieces of outdated financial advice that may have been useful once, but could now jeopardize your retirement security.

6 Outdated Financial Tips Still Circulating in Retirement Groups

1. “You Can Live Comfortably on 70% of Your Pre-Retirement Income”

This rule of thumb dates back to a time when retirees had pensions, low healthcare costs, and fewer years in retirement. The idea was that you wouldn’t need as much money because you wouldn’t be commuting, paying payroll taxes, or funding retirement accounts anymore. But today, the reality is different.

Healthcare costs have skyrocketed, with Fidelity estimating the average 65-year-old couple will need over $315,000 for medical expenses alone in retirement. Travel, hobbies, and even basic living expenses have all increased. And with people living longer, that 70% assumption often falls short, especially if you want to maintain or even improve your lifestyle in retirement.

Instead of relying on a decades-old percentage, calculate your retirement needs based on your actual projected expenses, factoring in inflation, healthcare, and the activities you want to pursue.

2. “Always Buy Your House. Renting is Throwing Money Away”

For many in past generations, buying a home was the default path to building wealth. But for retirees, this advice isn’t always the best fit. Owning a home comes with ongoing costs: property taxes, insurance, maintenance, and unexpected repairs. For older adults on a fixed income, these expenses can strain a budget, especially if the home is larger than needed.

Renting can sometimes be a smarter choice in retirement. It can free up home equity, reduce maintenance responsibilities, and allow more flexibility to move closer to family, medical care, or a better climate. It also avoids the risk of being “house rich but cash poor,” where most of your wealth is locked in a property you can’t easily spend.

Rather than following the blanket rule to buy, weigh the pros and cons based on your lifestyle, mobility, and financial goals.

3. “Stick to Safe Investments Once You Retire”

A generation ago, the idea was simple: as you near retirement, shift your portfolio almost entirely into bonds and other low-risk assets to protect your savings. While reducing risk is sensible, being too conservative can be dangerous in today’s environment.

Low-risk investments often yield returns that barely outpace inflation, if at all. With longer lifespans, retirees need their portfolios to grow enough to support decades of living expenses. Going too safe too soon can actually increase the risk of running out of money.

A more modern approach is to maintain a balanced, diversified portfolio that includes some exposure to equities, even in retirement. This doesn’t mean reckless investing. It means finding the right mix of safety and growth to sustain your retirement over the long term.

4. “Pay Off Your Mortgage No Matter What”

While becoming debt-free can feel liberating, paying off a mortgage at all costs isn’t always the best use of retirement funds. In the past, mortgage interest rates were high, so paying them off early saved significant money. Today’s rates are often much lower, and your cash may work harder in other investments, especially if those investments outpace your mortgage interest rate.

Additionally, using a large portion of your savings to eliminate your mortgage can reduce your liquidity. If unexpected expenses arise—medical bills, home repairs, or family emergencies—you may not have enough accessible cash without selling investments at a loss or taking on new debt.

Instead of automatically rushing to pay off your mortgage, compare the interest rate to your potential investment returns and your need for accessible cash.

5. “Social Security Will Cover Your Basic Needs”

This advice might have been somewhat realistic decades ago, but it’s a dangerous assumption now. The average monthly Social Security benefit in 2024 is around $1,907—hardly enough to cover housing, utilities, food, and healthcare for most retirees, let alone discretionary spending.

Relying heavily on Social Security can also make you vulnerable to policy changes or reductions in benefits. And if you retire early or have a lower lifetime income, your monthly payment could be significantly less.

Rather than viewing Social Security as your primary safety net, treat it as just one piece of a broader retirement income plan that includes savings, investments, and possibly part-time work or other income sources.

6. “You Don’t Need Life Insurance in Retirement”

This advice stems from the idea that once your children are grown and your mortgage is paid off, there’s no need to maintain a life insurance policy. But in reality, life insurance can still serve important purposes later in life.

It can provide liquidity for estate expenses, help pay off remaining debts, cover long-term care costs, or leave a financial legacy to loved ones or charities. For married couples, it can replace lost income if one spouse’s pension or Social Security benefits are reduced after death.

While you may not need the same type or amount of coverage as before, dismissing life insurance entirely could leave your family in a vulnerable position. It’s worth reviewing your needs with a financial advisor to determine whether keeping or adjusting your policy makes sense.

Why Outdated Advice Lingers in Retirement Circles

Much of this outdated advice persists because it worked well for earlier generations. In the past, retirees often had defined-benefit pensions, lower healthcare costs, and shorter retirements. The financial landscape was more predictable. But today’s retirees face volatile markets, rising costs, and longer lifespans, all of which demand updated strategies.

Retirement groups can be a double-edged sword. They offer community, support, and a wealth of shared experiences. But they can also spread oversimplified advice that doesn’t fit the realities of modern retirement. That’s why it’s crucial to evaluate any tip, no matter how confidently it’s shared, against current financial conditions and your personal situation.

How to Spot Bad Retirement Advice Before It Hurts You

Identifying outdated or harmful advice requires a healthy mix of skepticism and research. Always ask:

• When was this advice last updated? If it’s from decades ago, it may not reflect current economic realities.
• Does it account for my personal circumstances? Your health, goals, and income needs matter more than general rules.
• What do reputable, current sources say? Financial laws and best practices change regularly—make sure the advice is still valid.
• Have I run the numbers? Assumptions and averages are helpful starting points, but your budget should be built on actual figures.

The Bottom Line on Outdated Retirement Advice

The retirement world has changed dramatically in the last 20 to 30 years, but much of the advice being passed around has not. Blindly following outdated tips can lead to overspending, undersaving, or making investment choices that put your long-term security at risk.

Instead, approach every piece of advice with curiosity, not blind trust. Do the math for your situation, keep up with current financial trends, and consult professionals who understand the realities of retirement today, not just the way it used to be.

Why Modernizing Your Retirement Strategy Is Essential for Financial Security

Clinging to outdated retirement advice might feel comforting. After all, it often comes from people with good intentions and years of experience. But the truth is, what worked for your parents or neighbors may not work for you. Today’s retirement demands strategies that account for longer lifespans, higher costs, and changing income sources.

By recognizing and replacing outdated financial tips with modern, personalized strategies, you protect yourself from unnecessary risks and create a retirement plan that truly supports your lifestyle and goals.
