Retirement advice is as plentiful as the bills that roll in each month. But despite the avalanche of tips for boosting savings, managing debt and making sure a nest egg lasts a lifetime, people still make dreadful financial decisions. From embracing get-rich-quick schemes to treating a retirement account like an ATM, these gaffes can sabotage a financial plan, retirement portfolio or debt reduction program.
You can’t control how inflation or market performance affects your 401(k) balance. But you do have control over the financial decisions you make, and those choices can make a big difference in your retirement quality of life. Here’s a short list of financial unforced errors and some steps you can take to fix them.
1. Using 401(k) funds to buy a house
Buying a nice new house or a vacation property typically requires a sizable down payment. But raiding your 401(k) or individual retirement account (IRA) to do so is a no-no.
“One of my biggest pet peeves is when people consider pulling $100,000 or more out of a retirement account to buy real estate,” says Andrew Wood, a retirement planning adviser with Daniel A. White & Associates in Glen Mills, Pennsylvania.
There are several downsides to tapping your nest egg to put a roof over your head, Wood says. For one, withdrawals from a traditional 401(k) or IRA count as ordinary income, so you’ll pay taxes on that large distribution (which could even push you into a higher tax bracket). And if you’re younger than 59½, the IRS considers it an early withdrawal and, in most cases, assesses a 10 percent penalty on top of the regular tax bill.
Subtracting that big expense from your balance now also leaves you with fewer remaining investable assets (like stocks or mutual funds) accumulating returns for the future. That’s “a permanent setback,” says Greg McBride, chief financial analyst at Bankrate.
“Treating a retirement account as ‘found money’ when buying a home or when unplanned expenses arise may seem like a quick fix, but it’s a bad financial decision,” he says.
The fix: Build up funds for big-ticket purchases through a regular direct deposit from your paycheck to a dedicated savings account, or to a brokerage account subject to more tax-friendly capital gains rates. “Leave retirement money for retirement,” McBride says.
2. Carrying debt on too many credit cards
Debt is not your friend in retirement, especially if it’s stacked on credit cards with sky-high interest rates. The average annual percentage rate (APR) on plastic in June 2025 was 24.33 percent, according to LendingTree.
Many people fool themselves into thinking their debt is under control by carrying smaller, seemingly manageable balances on multiple cards. That may give them “emotional comfort” but masks the reality that they’re racking up sizable debt, says Rob Leiphart, a certified financial planner in Shelton, Connecticut.
“One card with a couple thousand dollars is not usually too much of an issue to pay off,” he says. “When you have five or six cards with that size balance, it’s a problem.” It’s also not uncommon for older adults: The average boomer has $6,754 in credit card debt, according to a recent Experian study, and the average Gen Xer owes $9,557 on their cards.
The fix: Look at your credit card debt in its entirety, not card by card. If the amount you owe is mushrooming, identify the root cause of the overspending and create a repayment strategy that is doable.
One option might be to consolidate credit card debt into a cheaper loan, such as a home equity line of credit (HELOC) or a personal loan. Average interest rates on those forms of debt were about 8.3 percent and 12.7 percent, respectively, in mid-June, according to Bankrate.
