To check your 401(k), log in to your plan provider’s website or mobile app, or call the phone number on your most recent statement. The dashboard shows your current balance, recent contributions, and how your investments are performing, usually updated as of the last market close. If you’ve never registered for online access or you’re trying to track down an old employer’s plan, the first step is figuring out which company actually holds the money.
Find Out Who Holds Your Plan
Your most recent pay stub usually names the provider receiving your 401(k) contributions. If it isn’t there, search your email for enrollment confirmations, annual disclosures, or investment change notices. Your employer’s HR department can tell you directly.
For a plan from a job you left, the Department of Labor’s Retirement Savings Lost and Found database at lostandfound.dol.gov searches for retirement plans tied to your Social Security number. It was created under the SECURE 2.0 Act. You’ll need a verified Login.gov account, which requires a government-issued ID and a mobile phone for identity verification. The results list plans you participated in and contact information for each plan’s administrator.1U.S. Department of Labor. Retirement Savings Lost and Found Database
Set Up Online Access
Go to your provider’s website and look for a registration or first-time user link. You’ll need your Social Security number, date of birth, and often a Plan ID or Group Number that identifies your specific employer’s plan. That code usually appears in your Summary Plan Description, the document your employer is required to give you that explains how the plan works, what it invests in, and how to file a claim for benefits.2Internal Revenue Service. 401(k) Resource Guide Plan Participants Summary Plan Description
You’ll create a username and password. Most providers now require multi-factor authentication, meaning you verify your identity a second way each time you log in: a text code, a push notification through the provider’s app, or a code from an authenticator app. Some support fingerprint or facial recognition on mobile devices. Turn these on during setup. Retirement accounts are high-value targets, and a stolen password alone shouldn’t be enough to get in.
What You’ll See When You Log In
Look for a tab labeled Account Overview, Balance, or Dashboard. This screen shows your total account value as of the most recent market close and how much it has changed over the past month, quarter, or year. Balances typically update daily.
One level deeper, you’ll find your individual fund holdings and how each one has performed. The same section shows your contribution history: how much came out of each paycheck and when each deposit posted. If your employer offers a match, verify those amounts appear too. A match that shows up on your pay stub but not in your 401(k) is a problem worth catching early.
The mobile app gives you the same information. If it supports biometric login, turn it on so you can check your balance without typing credentials each time.
Checking by Phone or Mail
If you’d rather skip the website, call the number on your most recent statement or in your benefits handbook. Most providers run automated phone systems that read your balance after you verify your identity with your Social Security number and a PIN, and you can also wait for a live representative.
Federal law requires your plan to send you a benefit statement at least once per quarter if you direct your own investments, which covers most 401(k) plans. If your investments are managed for you, the statement comes at least once per year.3Office of the Law Revision Counsel. 29 U.S. Code 1025 – Reporting of Participants Benefit Rights These statements show your balance, contributions, and investment performance. If you’ve opted into paperless delivery but want a physical copy, you have the right to request one.4U.S. Department of Labor. Reporting and Disclosure Guide for Employee Benefit Plans
Total Balance vs. Vested Balance
Your account may show two numbers: a total balance and a vested balance. Vested simply means yours to keep. Any money you contributed from your own paycheck is always 100% vested. Employer contributions, like matching funds or profit-sharing deposits, often vest on a schedule tied to how long you’ve worked there.5Internal Revenue Service. Retirement Topics – Vesting
The two common structures are cliff vesting, where you own nothing from the employer’s contributions until a milestone (typically three years) and then become 100% vested at once, and graded vesting, where your ownership percentage rises each year and reaches 100% after no more than six years.6Internal Revenue Service. Vesting Errors in Defined Contribution Plans If you leave before you’re fully vested, the unvested portion goes back to the plan. The vested number is what you’d actually walk away with today. Everyone becomes fully vested when they reach the plan’s normal retirement age or if the plan terminates.5Internal Revenue Service. Retirement Topics – Vesting
Read the Fees on Your Account
Every 401(k) charges fees, and they come out of your balance whether you notice them or not. Your plan administrator is required to send an annual disclosure explaining administrative fees, such as recordkeeping and legal costs, and how they’re divided among participants. You must also receive a quarterly statement showing the actual dollar amount deducted from your account during that period.7eCFR. 29 CFR 2550.404a-5 – Fiduciary Requirements for Disclosure in Participant-Directed Individual Account Plans
Each investment fund in your account also carries its own expense ratio, expressed as an annual percentage of the amount invested. Those fees compound over decades. Look for a fees or plan information section and compare expense ratios across your available fund options. Index funds and target-date funds tend to charge less than actively managed alternatives.
Compare Your Contributions to the 2026 Limits
While you’re logged in, check how much you’ve contributed this year. For 2026, the standard 401(k) contribution limit is $24,500. If you’re 50 or older, you can add $8,000 in catch-up contributions, for a total of $32,500. A higher catch-up of $11,250 applies if you’re between 60 and 63, bringing your maximum to $35,750.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
These limits apply to what you defer from your own paycheck, not to employer matching. Compare your year-to-date contributions to the cap that fits your age. Many providers let you adjust your contribution percentage from the same portal.
If Your Contributions Look Wrong
Catching late or missing deposits is one of the best reasons to check regularly. Federal regulations require your employer to deposit the money withheld from your paycheck into the plan as soon as it can reasonably be separated from the company’s general funds. For plans with fewer than 100 participants, a safe harbor rule gives employers up to seven business days after payday. In no case can the deposit happen later than the 15th business day of the month following the month it was withheld.9eCFR. 29 CFR 2510.3-102 – Definition of Plan Assets, Participant Contributions10Internal Revenue Service. You Havent Timely Deposited Employee Elective Deferrals
If your pay stub shows a withholding your 401(k) never received, raise it with your plan administrator or HR. Put the concern in writing so there’s a record. Many discrepancies are honest mistakes that get fixed quickly once flagged.
If it isn’t resolved, contact the Department of Labor’s Employee Benefits Security Administration. EBSA benefits advisors can be reached at 1-866-444-3272 or through their online portal. They’ll walk you through your options, including a formal investigation into the plan.11U.S. Department of Labor. Ask EBSA
Check Your Beneficiary While You’re There
Pull up your beneficiary information under a Beneficiary or Profile tab. This is who would receive your 401(k) if you died, and the designation on file with the plan overrides your will. If the form still names an ex-spouse or a deceased relative, that’s who the plan will try to pay. Review it after marriage, divorce, the birth of a child, or the death of a named beneficiary. Two minutes now saves a legal headache later.
Track Down Old Accounts
If you’ve worked for several employers, you may have 401(k) accounts scattered across multiple providers. Each has its own login, fees, and investment lineup, and tracking them separately makes it easier to lose money altogether. If you can’t remember where an old account is, the DOL’s Retirement Savings Lost and Found database can help you locate plans tied to your Social Security number.1U.S. Department of Labor. Retirement Savings Lost and Found Database Once you find them, checking each one uses the same steps: identify the provider, register for online access, and log in.
