Retirement Savings Plan Mistakes That Could Cost You Thousands
Hamilton Sound Credit Union
Use Cases
Mid-career professional – has been contributing to a 401(k) for years but has never reviewed fees or rebalanced. Small percentage drags compound into five-figure losses by retirement.
Late starter (age 45+) – playing catch-up but making high-risk allocations out of anxiety, or failing to take advantage of catch-up contributions allowed after age 50.
Job hopper – leaving old 401(k)s behind without rolling them over, incurring multiple account fees and losing control over asset allocation.
Preparation Checklist
[ ] Obtain recent statements for all retirement accounts (401(k), IRA, etc.).
[ ] Note current contribution percentages and any employer match details.
[ ] Review current asset allocation compared to your target retirement year or risk profile.
[ ] Check whether you have an adequate emergency fund (3–6 months of expenses) outside retirement accounts.
[ ] List any old 401(k) or IRA accounts that need consolidation.
Step-by-Step Workflow
Action: Gather and centralize your retirement account details. Decision criterion: If you cannot locate a statement or find fee information online, flag that account for follow-up before proceeding.
Action: Calculate your current total contribution rate (yours plus employer match) as a percentage of your gross income. Decision criterion: If the combined rate is below 10–15% (depending on your age and goals), increase your own contribution by at least 1–2% per year until you reach that range.
Action: Audit fees in each account. Compare expense ratios against low-cost index fund averages (generally 0.03%–0.15% range). Decision criterion: If any fund has an expense ratio above 0.75% or a sales load, consider replacing it with a lower-cost alternative within the same plan (or contact your HR about plan options).
Action: Rebalance your portfolio to match your target asset allocation (e.g., 90% stocks / 10% bonds at age 30, shifting toward bonds as you age). Decision criterion: If any asset class is more than 5 percentage points away from your target, rebalance by redirecting new contributions or executing a tax-free trade within the retirement account.
Action: Review and update beneficiaries for all retirement accounts. Decision criterion: If your life situation has changed (marriage, divorce, birth of child), update beneficiaries immediately; otherwise, confirm at least annually.
Action: Decide what to do with old 401(k)s from previous employers. Decision criterion: If you have more than one old 401(k), roll them into your current employer’s plan (if fees are lower and fund choices are good) or into a low-cost IRA. Avoid cashing out.
Quality Checks
Confirm that total contribution percentage (including catch-up if age 50+) aligns with your retirement timeline – consider using an online retirement calculator to validate.
Verify that after rebalancing, you are not over-concentrated in your company’s stock (no more than 10–20% of portfolio).
Check that you are not accidentally double-counting the same money across accounts (e.g., a Roth IRA and a taxable account).
Request a fee disclosure from your plan administrator if fees are still unclear; a good plan provides a clear summary annually.
Cautions
Avoid early withdrawals: Taking money out before age 59½ triggers a 10% penalty plus income tax – easily costing thousands in lost compounding.
Don’t stop contributions during market dips: Stopping when markets fall locks in losses and misses the recovery. Keep contributing through dollar-cost averaging.
Do not take a 401(k) loan lightly: If you leave your job, the loan becomes due immediately, and default counts as an early distribution subject to taxes and penalties.
Beware of “set it and forget it” inertia: Annual review is critical. IGNORING a 1% fee difference over 30 years can cost hundreds of thousands of dollars in lost growth.
Short FAQ
Q: I already have a 401(k) through work. Do I still need an IRA?
A: Not always. An IRA can offer more investment choices and lower fees than some employer plans, especially if you’ve maxed out the 401(k) match. Prioritize the 401(k) up to the match, then consider an IRA.
Q: How much could high fees really cost me?
A: Even a 1% higher fee on a $50,000 balance over 30 years can reduce your nest egg by roughly $50,000–$60,000, depending on returns. Small differences compound dramatically.
Q: Should I roll my old 401(k) into my new employer’s plan or into an IRA?
A: Compare both. An IRA often gives more fund choices and lower fees, but an employer plan may offer creditor protection and allow penalty-free loans. If fees are similar, convenience may tip the scale toward consolidation.
Q: Is it better to contribute to a Roth vs. traditional retirement account?
A: The decision depends on your tax bracket now vs. expected bracket in retirement. If you think you’ll be in a higher bracket later, Roth may be better. Many investors split contributions between both to hedge their tax bet.
