Retirement Savings Mistakes: 13 Signs Your Plan Is Off Track
Quick answer: The costliest retirement mistakes are skipping the full employer match, leaving money in cash, paying high fund fees and cashing out when changing jobs. Each can usually be fixed by adjusting your contribution, choosing investments, comparing fees or doing a direct rollover.↗ Share on X
You may be doing retirement savings wrong if you skip your employer match, keep your savings in cash for years, pay high fees without knowing it, or cash out your account when you change jobs. Those four mistakes are the most expensive, because they cost you money that would have grown for decades. The good news: each one can be fixed with a phone call or a form, often in one afternoon.
This article lists 13 warning signs, explains why each one matters, and tells you what to do instead. It is general education, not personal advice. Your situation is yours, so read the section near the end on when to talk to a professional.

How to Move Savings Into Your First Index Fund Safely →Retirement money grows through compound growth. That means your gains start earning their own gains. Over 20, 30 or 40 years, this effect becomes the biggest part of your balance.
So a mistake is not only the money you lose today. It is also everything that money would have earned later. A small fee or a few skipped years can mean a noticeably smaller account at the end. Fixing a problem early is worth much more than fixing it late.

1. You are not getting the full employer match
Many employers add money to your 401(k) (a workplace retirement account) when you add yours. This is called a match. If your company matches up to a certain percent of your pay and you put in less, you are leaving part of your pay on the table.
What to do: Ask HR or check your plan website for the exact match formula. Set your contribution at least high enough to get all of it.
2. You have no idea how much you are saving
If you cannot say what percent of your pay goes to retirement, you are guessing. A common rule of thumb is to aim for around 15% of your pay, counting any employer match, but the right number depends on your age, income and goals.
What to do: Look at your last pay stub. Find the retirement line. Divide it by your gross pay (pay before taxes).
3. Your money is sitting in cash inside the account
Some people contribute for years but never pick investments. The money lands in a cash or "money market" option and barely grows. Cash is useful for short-term needs, not for goals decades away.
What to do: Log in and check where your money is actually invested. If you are unsure what to choose, many plans offer a target-date fund, a single fund that adjusts its mix of stocks and bonds as you get closer to a chosen retirement year.
4. You pay high fees and do not know it
Every fund has an expense ratio, a yearly fee shown as a percent of what you have invested. A difference that looks tiny, like one fund charging several times more than another, adds up over decades.
What to do: Find the expense ratio of each fund in your plan's fee disclosure. When two funds do similar jobs, the lower-cost one is often worth a look. Broad index funds (funds that simply follow a whole market index) usually have low fees.
5. You cash out when you change jobs
Taking your 401(k) as cash when you leave a job usually means income taxes, and often an extra early-withdrawal penalty if you are under the IRS age limit. Worse, that money stops growing.
What to do: Roll it over instead. Your options are usually:
1. Leave it in the old plan (if allowed).
2. Move it to your new employer's plan.
3. Move it to an IRA (an individual retirement account you open yourself).
Ask for a direct rollover, where the money goes straight from one account to the other, to avoid tax withholding problems.
6. You started "later" and keep waiting
Waiting for a raise, a better job or a calmer month is the most common delay. Every year you wait is a year of growth you do not get back.
What to do: Start with any amount, even 1% or 2% of pay. Then raise it by 1 point every year, or every time you get a raise.
7. You never raise your contribution
Your pay went up over the years, but your savings rate stayed the same. That means your future income is not keeping up with your current lifestyle.
What to do: Check if your plan offers automatic increases. Turn it on so your contribution goes up a little each year without you having to remember.
8. All your money is in one stock
Holding a big share of your savings in a single company, especially your own employer, is risky. If the company struggles, you could lose your job and your savings at the same time.
What to do: Spread your money across many companies and types of investments. This is called diversification.
9. You panic-sell when the market drops
Selling after a big drop locks in the loss. Markets have gone through many drops over the years, and people who sold in fear often missed the recovery.
What to do: Decide your investment mix when you are calm. Write it down. When the news is scary, compare your plan to that note instead of your feelings.
10. You borrow from your 401(k) often
A 401(k) loan can look easy, but the borrowed money is not invested while it is out. If you leave your job, you may have to repay it quickly or it can be treated as a withdrawal, with taxes.
What to do: Build an emergency fund in a regular savings account so the retirement account stays untouched.
11. You ignore the tax side
There are two main types of accounts:
| Account type | You pay tax… | Often a fit when… |
|---|---|---|
| Traditional 401(k) / IRA | Later, when you withdraw | You expect a lower tax rate in retirement |
| Roth 401(k) / Roth IRA | Now, before money goes in | You expect a similar or higher tax rate later |
Many people never think about which one they use. Having some money in each can give you more choices later.
What to do: Check which type you have. If you are unsure which fits, this is a good question for a tax professional.
12. Your beneficiary form is old or empty
The beneficiary is the person who receives the account if you die. The form on file usually decides this, even over what a will says. Old forms after a marriage, divorce or birth cause real family problems.
What to do: Log in to each account and update the beneficiary. It takes a few minutes.
13. You have no picture of the finish line
Saving without any target is like driving without a destination. You do not need a perfect number, but you need a rough one.
What to do: Use your plan's retirement calculator or the free tools from your account provider. Also check your estimated Social Security benefit with your my Social Security account at ssa.gov.

When should you talk to a professional?
Talk to a licensed professional if:
- You are within about 10 years of retiring.

- You received an inheritance, a big bonus or a settlement.
- You are going through a divorce.
- You are thinking about withdrawing early.
Look for a fee-only fiduciary financial planner. A fiduciary is legally required to act in your best interest. "Fee-only" means you pay them directly instead of them earning commissions on products they sell you. You can check an adviser's background for free on FINRA BrokerCheck or the SEC's Investment Adviser Public Disclosure site.
Investing always involves risk. Past results do not predict future results, and any account can lose value.

Today, log in to your retirement account and answer just three questions: What percent am I saving? Am I getting the full match? Where is my money invested? Write the answers on paper. If any answer surprised you, fix that one first, and put a reminder on your calendar to repeat this check every year.
FAQ
What is the biggest retirement savings mistake?
For many workers it is not contributing enough to get the full employer match, because that match is extra money added to your account that you give up.
Should I cash out my 401(k) when I leave a job?
Usually it is costly: you may owe income tax and an early-withdrawal penalty, and the money stops growing. A direct rollover to a new plan or an IRA is a common alternative. Ask a tax professional about your case.
How do I know if my retirement fund fees are high?
Look up the expense ratio of each fund in your plan's fee disclosure and compare funds that do similar jobs. Broad index funds often have lower fees.
