A 401(k) statement arrives regularly — often quarterly — and gets glanced at for the total balance before landing in a drawer or a spam folder. That's understandable, but a few sections of the statement are worth actually reading, because they reveal things a balance alone doesn't show.
Vested vs. total balance
Your statement typically separates your own contributions (always fully vested — meaning fully yours) from any employer contributions, which may follow a vesting schedule. If you see a "vested balance" lower than your "total balance," that gap represents employer money you haven't fully earned yet under the plan's vesting rules — worth knowing, especially if you're considering leaving the job.
Contribution rate and year-to-date total
The statement usually shows your current contribution percentage and how much you've contributed year-to-date. This is a fast way to check whether you're on pace to reach an annual contribution goal, or whether a forgotten "temporary" reduction in contribution rate from months ago never actually got reversed.
Asset allocation
This section shows how your balance is spread across the specific funds you're invested in — often broken down by category, like U.S. stocks, international stocks, and bonds. It's worth checking periodically whether this still matches your intended strategy, since market movements alone can shift the proportions over time even without you making any changes (a stock market rally, for instance, can leave you more stock-heavy than originally intended).
Fees
Many statements include a fee disclosure section, showing the expense ratio of each fund you're invested in. These fees are easy to overlook because they're deducted automatically rather than billed separately, but they meaningfully affect long-term returns, as covered in more depth in our index fund guide.
What's worth actually checking each time
- Contribution rate — still what you intended it to be?
- Vested balance — especially relevant before making any decision about leaving a job.
- Beneficiary designation — often listed or accessible from the same account, and worth confirming after any major life change.
- Asset allocation drift — has it moved meaningfully away from your target mix since the last statement?
A 401(k) statement isn't designed to be exciting reading, but a five-minute skim a few times a year catches drift — in contribution rate, allocation, or vesting — long before it becomes a bigger surprise at retirement or a job change.
