9 Frightening Mistakes to Avoid Before You Retire

As the jack-o-lanterns flicker and the crisp October air kicks in, it’s the perfect time to think about spooks, scares and—most importantly—how some of the most shocking mistakes in retirement planning can haunt you for decades. At ThriveRight Financial Group, we believe retirement shouldn’t feel like walking into a haunted house alone. Instead, it should feel like stepping into a thoughtfully lit foyer, where you’re welcomed, guided, and confident about what lies ahead. Yet for far too many, the path to that calm moment of financial freedom is littered with traps and ghosts of regret.

Whether you’re five years from retirement or still decades away, these nine scary-mistakes lurk in the shadows. Let’s shine a flashlight into each of them, call out the skeletons in the closet, and show you how to wage your own exorcism with care, strategy and confidence.

Mistake 1: Underestimating the Length and the Cost of Retirement

It’s tempting to think retirement means “I’m done with work and bills.” But the reality is that you may live 20-30 years (or more) without a steady paycheck. The terrifying truth? According to one study by Visual Capitalist, 49 % of people underestimate the impact of inflation, 46 % underestimate how long they’ll live, and 42 % overestimate investment income.

Imagine you retire thinking you’ll live another 15 years, only to find you’re still going strong at age 90. Worse, imagine you didn’t budget properly for medical costs or inflation, and your nest-egg begins shrinking in real value. That’s a haunted financial house you want to avoid.

By confronting those possibilities now like “What if I live until 95? What if inflation persists at 4 % instead of 2 %? What if the market is volatile?” , you’ll walk into retirement with confidence—and not fear.

Mistake 2: Failing to Diversify Retirement Income Sources

Relying solely on one income stream—say, your pension or a single investment account—is a recipe for a financial nightmare. The Kiplinger advice rings loud: “Relying on a single source of retirement income” is one of the top mistakes.

Picture it like this: you enter your retirement house, and the lights go out because that one circuit failed. If you had only one light source, you’re plunged into darkness. If you had backup lights, battery lamps, a generator—you’re secure.

Build multi-legged income frameworks: Social Security timing, withdrawals from tax-diverse retirement accounts, possibly a lifetime income annuity, maybe some real estate or business cash flow. Don’t let the lights go out on you.

Mistake 3: Ignoring the Impact of Market Downturns and Sequence-of-Returns Risk

One of the scariest monsters in retirement isn’t just inflation or longevity—it’s market timing and sequence of returns. The dreaded scenario: you retire, the market tanks in your first few years, you withdraw from your portfolio to cover expenses, and your savings never bounce back fully. The Charles Schwab guidance is stark: selling assets in a downturn and inefficient distribution strategies are among top mistakes.

Think of it as stepping into a haunted mansion and hitting the floor-boards before the hidden trapdoor opens. If you’re not prepared with a buffer, you fall in. Emphasize early planning for this risk: maintain a cash or short-duration buffer before retirement, build a withdrawal plan that adapts, and ensure you aren’t forced into selling at the worst possible time.

Mistake 4: Collecting Social Security Too Early or Without Strategy

The ghosts of “what-if I took it earlier” and “what-if I delayed” may haunt many. Taking your Social Security benefit at age 62 might feel like a welcome treat—but it could cost you for life in smaller monthly payments. Schwab again spells out the truth: waiting can increase benefits and improve portfolio longevity.

Imagine you took the candy from the trick-or-treat bag too early without checking its value, and now your bag shrunk. By contrast, delaying is like harvesting more candy later—if you can wait. Examine your health, family history, cash-flow needs and other income sources to decide when claiming Social Security is truly optimized.

Mistake 5: Not Tax-Planning Retirement Withdrawals

Taxes can sneak into your financial house like a quiet ghost—unexpected, overlooked, and harmful. Many retirees neglect efficient withdrawal sequencing from tax-deferred accounts, often landing in higher tax brackets, choke points or forced required minimum distributions (RMDs) at age 73 or 75.

That’s akin to inviting a phantom into your home: you budget one expense, but then the taxman shows up and drains money you thought safe. Construct “tax floor” and “tax ceiling” strategies, evaluate Roth conversions, and plan distributions so that the tax ghost doesn’t scare away your peace of mind.

Mistake 6: Underestimating Healthcare and Long-Term Care Costs

The scariest surprises often come from what you didn’t see coming. Healthcare and long-term care are two such lurking beasts. The New York Life Insurance Company lists underestimating medical costs and ignoring long-term care as key mistakes.

Imagine moving into your retirement home only to discover the plumbing is modern but the foundation is crumbling. The fancy finishes don’t matter if you didn’t account for servicing the structure. Similarly, good lifestyle extras don’t last if you didn’t budget in bigger healthcare or assisted-living expenses. 

Mistake 7: Neglecting Inflation and Cost-of-Living Adjustments

Time passes. Crises come. Prices rise. Yet many retirees ignore that today’s dollar might buy less tomorrow. According to Visual Capitalist, nearly half underestimate inflation’s creep.

Think of walking through a haunted forest: each step seems safe, but the ground silently sinks beneath you inch by inch until you’re waist-deep. That’s inflation. Run range scenarios: if inflation averages 3 % vs. 5 % over 20+ years, what happens to your purchasing power? Then take a time to plan accordingly.

Mistake 8: Failing to Treasure the “Quiet Zone”—Lifestyle & Purpose in Retirement

Money matters—but so does meaning. One of the more subtle frights occurs when retirees realize they “have the money” but not the purpose—or worse, they outlive their relevance. The worry isn’t always about income; it’s about identity. Studies from the Transamerica Center for Retirement Studies show workers across generations are increasingly concerned about what retirement will “look like.”

Walking into retirement with no plan for how you’ll spend your time, where you’ll live, how you’ll feel—now that’s chilling. Retirement is more than just “turning off the alarm”; it’s about designing purpose beyond paycheck. We incorporate lifestyle conversation into our financial planning so you don’t end up haunting your own blueprint.

Mistake 9: Not Working With a Trusted Advisor & Falling into DIY Traps

Trying to navigate retirement planning alone is like walking through a mansion full of secret passageways without a map. According to an article on “Why smart people make retirement-planning mistakes,” people who procrastinate or make inconsistent time choices are twice as likely to regret it.
