Top Financial Planning Mistakes to Avoid in Your 40s and 50s

by | Jun 3, 2025 | Fiduciary Financial Advisor | 0 comments

our 40s and 50s are often your peak earning years—and also a critical time to make sure your financial plan is working for you, not against you. With retirement looming closer and life expenses still running high, it’s easy to make decisions now that can compromise your financial independence later. At Manna Wealth Management, we help individuals and families avoid costly missteps so they can confidently move into the next stage of life.

Here are the top financial planning mistakes to avoid in your 40s and 50s, and how to correct course if you’ve already made one.


1. Not Having a Clear Retirement Plan

Too many people assume that retirement planning can wait until they’re “closer to the finish line.” The truth is, the earlier you plan, the more control you have over your financial future. Not calculating how much you’ll need—or when you can afford to stop working—can derail your retirement dreams.

What to do:

  • Run retirement projections with a financial advisor.

  • Determine your “number” and work backwards to build a savings plan.

  • Consider inflation, healthcare costs, and lifestyle choices.


2. Underfunding Retirement Accounts

Even if you’re contributing to your 401(k), are you maxing it out? Are you taking advantage of catch-up contributions at age 50? Many individuals underfund their retirement savings simply because they underestimate future expenses or prioritize short-term spending.

What to do:

  • Max out 401(k), IRA, and HSA accounts when possible.

  • Take advantage of employer matches—it’s free money.

  • Use catch-up contributions once you hit age 50.


3. Ignoring Tax Diversification

In your 40s and 50s, you need to think beyond tax-deferred savings. Relying solely on pre-tax retirement accounts like a 401(k) can lead to heavy tax burdens in retirement.

What to do:

  • Consider Roth IRAs or Backdoor Roth contributions for tax-free growth.

  • Explore taxable brokerage accounts for flexibility.

  • Work with a financial advisor to develop a tax-efficient withdrawal strategy.


4. Carrying High-Interest Debt

Credit card balances and personal loans can significantly erode your net worth over time, especially as interest compounds. By your 40s and 50s, high-interest debt should be aggressively managed—if not eliminated entirely.

What to do:

  • Prioritize paying off debts with interest rates above 6%.

  • Consider debt consolidation if you’re managing multiple payments.

  • Avoid borrowing from retirement accounts to pay off consumer debt.


5. Neglecting Insurance Coverage

Many people forget to revisit their insurance policies as their financial lives grow more complex. Inadequate life, disability, or long-term care insurance can expose your family to financial risk.

What to do:

  • Review your life and disability coverage annually.

  • Consider long-term care insurance by your early 50s.

  • Evaluate umbrella liability coverage if your assets are growing.


6. Failing to Update Your Estate Plan

An outdated or nonexistent estate plan can lead to unnecessary taxes, family disputes, and probate delays. If you’ve gone through major life events—marriage, divorce, children, or buying property—it’s time to revisit your plan.

What to do:

  • Ensure you have a valid will, power of attorney, and healthcare directive.

  • Consider setting up trusts to manage assets and reduce taxes.

  • Review and update beneficiaries on all retirement and investment accounts.


7. Ignoring Investment Allocation and Risk

In your 40s and 50s, it’s important to strike a balance between growth and capital preservation. Too much risk exposes you to market downturns. Too little risk could leave you underfunded for retirement.

What to do:

  • Review your portfolio’s risk level annually.

  • Diversify across sectors and asset classes.

  • Rebalance to stay aligned with your retirement timeline.


Final Thoughts

Avoiding these common financial planning mistakes can be the difference between a comfortable retirement and a stressful one. Your 40s and 50s are a time to fine-tune your financial plan, maximize your wealth-building potential, and protect what you’ve already worked so hard to build.
