Reading your 401(k) statement

Every quarter, your 401(k) provider mails or emails you a statement about your retirement account. Most people give it 30 seconds, see a big number, feel either good or bad, and move on. There’s much more useful information in there, and three numbers in particular that decide whether you retire on time or five years late.

The layout differs by provider (Fidelity looks one way, Empower looks another), but every statement contains the same conceptual sections in roughly this order. We’ll walk through each one and flag what to actually look at.

The cover page, balance, contributions, and growth

The first page is the snapshot. It shows three big numbers that explain what changed in the quarter:

• Beginning balance. What the account was worth on the first day of the period.
• Contributions. What you put in (your salary deferrals) plus what your employer added (the match, plus any profit-sharing).
• Investment performance / market change. How much the value moved up or down because of what your investments did, not because of contributions. Negative numbers here in a bad quarter are normal, they don’t mean money was lost in any permanent sense, just that the market value declined.
• Ending balance. Beginning + contributions +/− market change.

A useful sanity check: contributions vs. market change. Early in your career, contributions usually drive most of the balance growth. Later, market change should start to dwarf contributions. If you’ve been contributing for 15+ years and the market change is still smaller than your contributions, that’s a signal to check your investment selections, your money may be sitting in a fund that isn’t actually growing.

Vested vs. unvested balance, the part that’s actually yours

Most statements show two balance numbers, and they’re often different:

• Total balance. Everything in the account.
• Vested balance. The portion that’s yours to keep if you leave the company tomorrow.

Money you contributed yourself is always 100% vested immediately. The employer match is what can be partially or fully unvested.

Vesting schedules come in two common flavors:

• Cliff vesting. 0% vested for X years, then 100% all at once. (Example: 0% for 3 years, then 100% at year 3.)
• Graded vesting. A percentage each year. A common one: 20% per year over 5 years.

Why this matters: if you’re thinking about changing jobs, the difference between leaving on March 31 and waiting until April 15 could be thousands of dollars in vested match. The employer’s portion of your match is real money that you only fully own once the vesting schedule says so.

Holdings, what you actually own

This section lists each fund you’re invested in. For each one you’ll typically see:

• Fund name (e.g., “Vanguard Target Retirement 2055”)
• Fund ticker (4-5 letters)
• Current value
• Number of shares or units
• % of your account
• Expense ratio (sometimes hidden in a separate “fee” section)

The two columns to look at: % of account and expense ratio. The first tells you whether you’re diversified or accidentally put 80% into one thing. The second tells you what you’re paying.

Performance, the numbers you can almost ignore

Most statements show 1-month, 3-month, year-to-date, 1-year, and sometimes 5-year and 10-year returns for each holding. They look precise. They’re mostly noise for long-term retirement money.

Here’s why: short-term returns measure what happened to the market, not what your investment is going to do. A stock fund might be down 18% year-to-date in a recession year and up 28% the following year. The 10-year average matters far more, and even that is just a rough estimate of long-run behavior.

What to look at: 5-year and 10-year annualized returns of broad index funds usually fall in a reasonable range (recently around 7% to 10% per year for U.S. stock indexes, lower for bonds). If a single fund in your account has a 10-year return that’s dramatically lower than a comparable broad index, say, 4% when the S&P 500 returned 10%, that’s a fund worth examining. It might be charging high fees for performance it doesn’t deliver.

Fees, the page nobody reads

Somewhere in the statement (often pages back, sometimes only in annual disclosures), there’s a fees section. One of the more important numbers here is the expense ratio on each fund.

An expense ratio is the annual percentage of your invested money that the fund company keeps for running the fund. It comes out of your returns automatically, you never see it as a line item, which is exactly why people miss it.

Reasonable ranges in 2026:

• Low-cost broad index fund: 0.03% to 0.20% per year. (Three to twenty cents per $100 invested per year.)
• Target-date fund: 0.10% to 0.75%, depending on provider.
• Actively managed mutual fund: 0.50% to 1.25%, with older or specialty funds sometimes higher.
• Anything above 1.0% deserves a hard look. Over decades, that fee is meaningful.

To put fees in context: a 0.75% fee on a $100,000 balance is $750 per year, every year, even when the fund loses money. Over 30 years on a growing balance, the difference between a 0.05% and a 0.75% fund can easily exceed $100,000 in lost returns. Same fund, same market, fees alone are the difference.

Most 401(k)s also charge a small administrative fee, anywhere from a few dollars to about 0.50% of assets per year, that pays the recordkeeper and trustee. This is usually unavoidable. What you can control is the expense ratios of the funds you pick.

The three numbers to actually track

Out of everything on the statement, three numbers do most of the work for long-term planning:

1. Vested balance. Not total balance. Vested. This is what’s actually yours if you leave tomorrow, and it’s the honest number for retirement projections.
2. Annual contribution rate (yours + employer’s). If you’re contributing 6% and your employer matches 50% of that, your combined rate is 9% of salary. Over a career, the savings rate matters more than the investment selection.
3. Weighted average expense ratio. If 60% of your balance is in a fund charging 0.05% and 40% is in one charging 0.85%, your weighted average is 0.37%. Most providers don’t print this number; you can calculate it in two minutes once a year. If it’s above 0.50%, look at whether cheaper alternatives exist inside your plan.

Common red flags that warrant a closer look

• Single-fund concentration above 50%. Often happens when somebody picks one fund at signup and never rebalances. Even a target-date fund is fine here, but a single-stock fund or single-sector fund at 50%+ is risk concentration most people didn’t mean to take.
• Old company stock that’s become a huge share of the balance. Employees at certain companies end up with 60%+ in their employer’s stock through grants and ESPP rollovers. If the company has a bad year, both your job and your retirement take a hit.
• An expense ratio you can’t identify. If a holding’s expense ratio is missing on the statement, find it on the fund provider’s website. Fees you don’t see still get charged.
• You’re not getting the full match. If your contribution rate is below the “match ceiling”, for example, you’re saving 3% but your employer matches up to 6%, you’re leaving employer money behind. The statement shows your contribution percentage; HR has the match formula.

Action steps after reading your statement

1. Confirm the contributions match your paystub. Add your year-to-date 401(k) deductions from your December paystub and compare to the “your contributions” total on the year-end statement. Should match exactly.
2. Check that you’re capturing the full match. If your employer matches up to 6% and you’re contributing 4%, the difference is essentially declining a piece of your compensation. Adjusting your contribution rate usually takes about three minutes on the provider’s website.
3. Look at your weighted expense ratio once a year. If it’s above 0.50% and your plan offers low-cost index funds, consider whether you want to migrate. (This is a personal decision; we’re flagging the math, not telling you what to do.)
4. Save the statement. A folder in cloud storage works. Year-over-year comparisons are the only way you’ll notice slow trends, fee creep, balance stagnation, sector drift.
5. Don’t check it daily. Quarterly is plenty. People who watch their balance every day tend to be more likely to panic-sell during dips, which is one of the more costly retirement mistakes documented in research on investor behavior.

What this lesson is NOT

This is not investment advice, and it does not recommend specific funds, an allocation, or a contribution amount for you. What the right mix looks like depends on your age, your other savings, and your tolerance for risk, none of which a statement can tell you. Use this to read your statement clearly, and use your plan documents, or a fiduciary adviser when the stakes are high, to decide what to change.
