Why pre-retirement decisions carry extra weight

The years immediately before retirement are when financial choices become harder to undo. An account withdrawn, a benefit claimed, or a debt carried forward can set the terms of your income for decades. This article covers six common mistakes that can quietly reduce retirement security, and what you can do about each one before it becomes permanent.

None of this is personalised financial advice. Every situation differs, and a licensed financial adviser or planner can help you apply general principles to your specific numbers and goals.

The six mistakes and how to sidestep them

The errors below come up often in financial planning conversations precisely because they feel reasonable in the moment. Understanding why they happen makes them easier to catch.

1

Withdrawing from retirement accounts early to cover short-term expenses.

Why it happens: A financial shortfall feels urgent, and a 401(k) or IRA balance can look like an accessible cushion. The long-term cost is easy to overlook when a current bill is due.

How to avoid: Build an emergency fund outside your retirement accounts so short-term needs do not require early withdrawals. If you are under 59 and a half, early withdrawals from most tax-advantaged accounts trigger ordinary income taxes plus a 10% federal penalty, and the withdrawn amount loses all future tax-deferred growth. Consult a financial adviser before touching these accounts.
2

Claiming Social Security benefits as soon as you become eligible at age 62.

Why it happens: Many people assume collecting sooner means collecting more over a lifetime, or they simply need the income and do not model the long-term numbers.

How to avoid: Each year you delay claiming past 62 (up to age 70) increases your monthly benefit by a meaningful percentage. If your health and other income sources allow it, waiting can substantially raise your lifetime income. The Social Security Administration's online tools can help you model different claiming ages.

Underestimating healthcare costs in retirement.

Why it happens: Many pre-retirees assume Medicare covers most medical expenses, so they do not set aside dedicated healthcare savings. Medicare has premiums, deductibles, and significant coverage gaps.

How to avoid: Research what Medicare does and does not cover well before you retire. Dental, vision, hearing, and long-term care are areas where out-of-pocket costs can be substantial. Review common Medicare coverage misconceptions so surprise bills do not catch you off guard. A health savings account (HSA), if you are still eligible to contribute, can help you set aside pre-tax funds for future medical costs.
4

Entering retirement with high-interest consumer debt still outstanding.

Why it happens: People often plan to pay off debt gradually, then find that work ends sooner than expected, whether through choice, health, or layoffs, before the balance is gone.

How to avoid: Make debt elimination a pre-retirement financial priority, starting with the highest-interest balances. A fixed income makes it much harder to carry monthly interest charges without drawing down savings faster than planned. Review your retirement budget against your fixed income sources to see how debt payments affect your monthly picture.
5

Ignoring housing costs and assuming the current home is the only option.

Why it happens: Home is familiar, and most people have not compared the true ongoing costs of staying put against alternatives. Property taxes, maintenance, and potential accessibility needs can grow significantly in later years.

How to avoid: Calculate the realistic annual cost of your current home, including taxes, insurance, repairs, and any modifications for aging in place. Then compare that figure to alternatives. Weighing aging in place against assisted living can reveal options many families have not fully considered.
6

Failing to update beneficiary designations and legal documents before retiring.

Why it happens: These documents are set up once and then forgotten. Life changes, including marriages, divorces, and deaths, mean designations can be years out of date by the time they matter.

How to avoid: Review all beneficiary designations on retirement accounts, life insurance policies, and bank accounts at least every few years and after any major life event. Confirm that your will, power of attorney, and healthcare directives reflect your current wishes. An estate attorney can help you identify gaps before they become problems.

10%

Federal early withdrawal penalty on retirement accounts

The IRS applies a 10% early withdrawal penalty on most retirement account distributions taken before age 59 and a half, on top of ordinary income taxes.

Reduction in Social Security benefit for early claimers
