Can You Lose Money in a 401(k)?

1. The short answer, before the caveats

Quick Answer: Yes, you can lose money in a 401(k). A workplace 401(k) plan is a container, not an investment. What sits inside it is stock and bond funds, and those fall. Nothing about the account is insured against a market drop, and no federal guarantee restores a lost balance.

Can you lose money in 401k plans in a way that actually matters? People ask that two different ways, and they deserve two different answers. The first is about a bad month on a statement. The second is a quieter fear: could the money simply be gone?

Those are not the same risk. A market drop moves your balance without changing how many fund shares you own. A cash-out, a fee, or a penalty removes dollars permanently.

Here is the distinction that runs through the rest of this guide:

• A paper loss. Your funds are worth less today. You still own every share. History says the balance recovers if you leave it alone.
• A realized loss. You sold at the bottom, or you took the cash and paid tax and a penalty on it. Those dollars are gone.
• A slow loss. Fees skim a percentage every year, in good markets and bad. This one never announces itself.

Across the money guides on DollarVisor, this is the split that decides whether a scary statement is a real problem or just weather.

The tax code draws the same line. You cannot claim a capital loss when a 401(k) falls, because the IRS treats the account as already tax-favored. A taxable brokerage account gives you a deduction for a bad year. Your 401(k) does not.

Before the numbers, here is a plain-English walkthrough of how a retirement account behaves when markets fall:

2. What can actually be taken from you

Quick Answer: Your own payroll contributions can never be forfeited. The IRS is explicit on that point. Employer money is different: leave before you are vested and the match goes back to the plan, a loss that has nothing to do with markets and everything to do with your plan’s vesting schedule.

Two things people confuse are worth separating early, because only one of them is a market question.

Your salary deferrals are yours from the first paycheck. Your employer cannot claw them back, and a bankrupt employer cannot reach them either, because plan assets are held in a trust separate from company money.

The match is a different story. It follows a schedule, and quitting a month early can cost you the whole thing. Our guide to when the employer match becomes yours runs that math in full.

So the honest answer has three parts. Markets can cut the value, vesting rules can take the match, and your own withdrawal decisions can take the rest.

3. How much a real down year costs, in numbers

Quick Answer: In 2022, average Vanguard 401(k) balances fell 20% and the median fell 23%. Two years later the average hit a record $148,153. That pairing, drawn from the same dataset behind our investing and retirement guides, is the clearest picture of what a bad year does.

Most coverage of 401(k) losses stops at the drop. The more useful comparison puts a down year and an up year side by side, using the same five million participants, and asks what changed besides the balance.

Read the trading row twice. In the worst year of the decade for savers, 94% of participants made no exchange at all. The panic that headlines describe is rarer than the headlines suggest.

The row that should worry you is the last one. Hardship withdrawals nearly doubled while balances were climbing, which means the permanent losses rose in the good year, not the bad one.

4. Five ways to lose money in a 401(k), ranked by permanence

Quick Answer: Market drops are the loudest way to lose money in a 401(k) and the only one that reliably reverses. Fees, cash-outs, hardship withdrawals and a concentrated bet on your employer’s stock are quieter, and each one is permanent. A rollover into an IRA avoids the worst of them.

The Labor Department’s own example is worth quoting. On a $25,000 balance left alone for 35 years at a 7% return, paying 0.5% a year leaves $227,000. Paying 1.5% leaves $163,000.

One percentage point of fees cost $64,000 on a $25,000 starting balance, and no statement ever showed it as a loss.

5. $100,000 through a 20% drop: three responses

Quick Answer: The drop costs you the same on day one no matter what you do. What you do next sets the real damage. Holding and continuing to buy, which is dollar-cost averaging in practice, recovered the full balance in this scenario. Cashing out kept barely half of it.

Take a $100,000 balance into a year that behaves like 2022. It ends at $80,000. Now run the next year forward at the 25% gain the S&P 500 delivered in 2024.

The cash-out row is worse than it looks, because state income tax usually applies on top. A saver in Texas or Florida, where there is no state income tax, keeps more of the same withdrawal than a saver in California does.

Notice also what the middle row costs. Selling to cash did not create a headline loss. It quietly locked in $16,800 by missing the recovery.

6. The loss that keeps growing in good markets

Quick Answer: Hardship withdrawals have climbed every year since 2021, through both falling and rising markets. That is money leaving accounts permanently, and it usually happens at a job change, which is why what happens to your 401(k) when you quit matters more than any single bad quarter.

The rate more than doubled in three years while balances hit records. Whatever is driving it, market fear is not the explanation.

Job changes make it worse because the paperwork arrives late. In a nationally representative survey, the Government Accountability Office found about 80% of eligible participants did not know all four of their distribution options, and about 40% did not understand the tax consequences.

7. Could you lose the entire balance?

Quick Answer: A diversified fund cannot go to zero, because that would require every company in it to fail at once. One stock can. The realistic path to losing everything is a balance stacked in your employer’s shares, which is why asset allocation by age matters more than fund picking.

Three fears come up here, and only one of them holds up.

• Your employer goes bankrupt. Your account is not affected. Plan assets sit in a trust that creditors cannot reach, separate from company money.
• The market crashes. A broad index fund falls hard and recovers. It has never gone to zero, because it holds hundreds of companies.
• Your account is mostly company stock. This is the real risk. Your paycheck and your retirement now depend on one business.

Vanguard treats a portfolio as balanced only when company stock sits below 20% of the account. At the end of 2024, 78% of participants cleared that bar, up from 69% a decade earlier.

If you want money outside your employer’s plan for the same retirement, a backdoor Roth IRA is the common next step for higher earners.

8. What to do when your 401(k) is losing money

Quick Answer: Work through the account in order, from the things you control to the things you do not. Fees, concentration and your mix come first. Deciding whether to rebalance your portfolio comes last, and selling out of fear does not appear on the list at all.

These five steps take about an hour with your plan statement open.

1. Confirm the loss is on paper. Compare your balance with your total contributions to date. If contributions still exceed the shortfall, nothing has been realized.
2. Find your total fee. Your plan must give you an annual comparison chart. Add the fund cost and the plan administration cost, then judge the total.
3. Check the company stock share. If one employer sits above 20% of the balance, that is the concentration to reduce first.
4. Match your mix to your timeline. A saver 25 years out and a saver two years out should not hold the same allocation after the same drop.
5. Keep the match. Cutting contributions during a drop means buying fewer shares at lower prices and giving up free employer money.

One thing not on the list is moving everything to a stable value or money market option. That converts a paper loss into a locked-in one, which is exactly what the middle row of the earlier table costs.

9. The verdict

Quick Answer: Can you lose money in 401k accounts? Yes, and the honest follow-up is that most of that loss is temporary while a smaller share is permanent. Sort every drop into those two buckets and the right response is usually obvious.

The 2022 evidence is about as clean as personal finance gets. Balances fell a fifth, 94% of savers did nothing, and by 2024 the average account was at a record high.

The losses that stuck were the quiet ones. A percentage point of fees. A cash-out taxed and penalized at a job change. A hardship withdrawal that rose every year regardless of what markets did.

So watch the right number. A red statement in a falling market is normal, and our investing guides exist to keep that in proportion. A withdrawal form is the one worth a second opinion.

10. Frequently Asked Questions

1. Can you lose your entire 401(k)?

Only in narrow cases. A diversified stock fund would need every company inside it to fail at once, which has not happened. The realistic route to a near-total loss is holding mostly your employer’s stock and watching that one company collapse. Your employer going bankrupt does not touch a diversified balance, because plan assets are held in a separate trust.

2. Why is my 401(k) losing money when the market is up?

Three usual causes. Your funds may not track the index in the headline, since a bond fund or an international fund can fall in a year US stocks rise. Fees come out regardless of performance. Or you may be comparing a balance after a withdrawal or a loan repayment rather than a pure investment return.

3. Is a 401(k) insured against losses?

No. Federal deposit insurance covers bank accounts, not investments, and no agency reimburses a market decline. What federal law does protect is the account itself: your own contributions cannot be forfeited, and plan assets are held in trust away from your employer’s creditors.

4. Should I stop contributing while my 401(k) is down?

Usually not. Contributions made during a drop buy more shares at lower prices, and stopping often means giving up the employer match, which is an immediate loss. If cash flow is genuinely tight, cutting to the match rate keeps the free money while easing the payroll deduction.

5. Do 403(b) and 457(b) plans lose money the same way?

Yes. They hold the same kinds of funds and carry the same market risk, with different withdrawal rules. Our comparison of 403(b) and 401(k) plans covers where those rules diverge, and 457(b) plans avoid the 10% early-withdrawal penalty in most cases.
