Small drips sink big buckets. Retirement accounts are full of quiet charges and penalties that steal growth without making a sound. Some are baked into investments; others show up when you move money or miss a rule. Know where the leaks are, plug what you can, and plan for the rest. Do a quick annual fee checkup and you’ll keep more of what you saved.
1. Fund Costs You Can’t See

Expense ratios, trading costs, and 12b-1 marketing fees don’t hit your checking account, but they hit returns. Even tiny differences compound a lot over 10 or 20 years. Read the fee table and pick cheaper share classes when you can. The SEC’s guide to mutual fund and ETF fees shows what to look for.
2. Plan Admin and Recordkeeping Add-Ons

Your 401(k) may deduct plan administration, recordkeeping, and custodial fees from returns or directly from your balance. These charges vary by plan size and provider. Check your 404a-5 disclosure and summary plan description to see what you’re paying. DOL’s Understanding Your Retirement Plan Fees explains the common line items.
3. Managed-Account “Advice” Layers

Many plans offer managed accounts that set allocations for you, but convenience isn’t free. Fees are often charged as a percent of assets and can run high relative to the service. Review whether the tool improves results after costs. GAO’s report on managed-account fees shows how those add-ons stack up over time.
4. Variable Annuity Surrender Charges and Riders

Annuities can offer lifetime income, but variable contracts often come with steep surrender periods and extra riders. That means penalties for early withdrawals and ongoing mortality and expense charges. If it’s inside an IRA, make sure you’re not paying for tax deferral you already have. FINRA’s explainer on annuity fees lays out the typical costs.
5. Missed RMD Penalties

If you’re required to take a minimum distribution and don’t, the IRS can assess an excise tax on the shortfall. The rate can drop if you fix it quickly, but it’s still real money. Put recurring reminders on your calendar and coordinate across accounts. See the IRS RMD FAQ for current penalty rules.
6. Cash-Out and 60-Day Rollover Traps

Taking a check when you leave a job triggers 20% mandatory withholding, and if you miss the 60-day window, you may owe tax plus the 10% early withdrawal penalty if under 59½. A direct trustee-to-trustee rollover avoids the withholding hit. The IRS rollover guidance spells out both rules.
7. Medicare Surcharges After Big IRA Draws

Large withdrawals can push your income high enough to trigger IRMAA—extra monthly amounts for Part B and Part D. That’s not a fund fee, but it’s a retirement leak tied to your distributions. Plan conversions and withdrawals with IRMAA brackets in mind. Medicare’s IRMAA notice explains who pays and why.
8. Low-Yield Cash Sweep

Uninvested cash in brokerage or IRA accounts may default to a sweep program that pays much less than alternatives. That “cash drag” cuts long-term returns. Ask what your sweep options are and whether a money market fund is available. The SEC’s bulletin on bank sweep programs lists the questions to ask.
9. Transfer-Out and Closure Fees

Moving an IRA or brokerage account? Your current firm may charge an ACAT transfer or account termination fee. Some new firms reimburse, but not all. Always check the fee schedule before you initiate a move. The SEC’s guidance on transferring your investment account flags these charges.
10. Paper Statements and Check Processing

Many providers charge for paper mail, physical checks, or overnight delivery. These aren’t huge, but repeat them a few times and it adds up. Switch to e-delivery and direct deposit to keep more cash compounding.
11. Brokerage-Window Trading Costs

Self-directed brokerage windows inside 401(k)s can unlock more choices, but often come with trade commissions, fund transaction fees, and separate platform charges. If you only place a few trades a year, those fees can overwhelm any benefit. Compare total costs to a low-cost index fund in the core menu.
12. Wrap Fees You Don’t Use

Advisory “wrap” programs bundle advice and most trading into one asset-based fee. If you trade little or mainly hold funds, you might be overpaying for execution you don’t need. Read the brochure for extra costs on trades done outside the wrap. The SEC explains how wrap fee programs work and what to check.
13. Cash-Heavy Defaults

Stable value or money market defaults can be helpful for short horizons, but staying there for years means missing market growth. The leak isn’t a fee; it’s opportunity cost. Revisit your allocation at least annually so your risk level matches your timeline.
14. IRA Custodian Maintenance or Termination Fees

Some custodians still charge small annual fees or a one-time fee to close or transfer an IRA. It’s easy to miss these in long fee schedules. If you’re consolidating, ask the new custodian about reimbursements and get them in writing.
15. Excess IRA Contribution Penalties

Contribute too much or to the wrong type of IRA and you may owe a 6% excise tax each year until you fix it. The fix is usually removing the excess (plus earnings) by the tax-filing deadline. The IRS page on excess IRA contributions outlines the 6% rule and how to correct it.
