5 Best Apps to Find a Lost 401(k) (2026)

Left a job and never rolled over your retirement account? You’re not alone. Millions of Americans have old 401(k) balances sitting with former employers—and the right apps to find a lost 401k can point you toward official tools without charging a finder’s fee.

This shortlist compares five options people actually use in 2026: guided mobile apps, free rollover helpers, paid finders, and retirement dashboards. 

We make Asset Recovery: Lost 401k, so you’ll see it featured first—with honest notes on everyone else.

Quick comparison

• Asset Recovery: Lost 401k — Free iOS/Android guide to official DOL and PBGC search links; no SSN in the app.

• Capitalize — Free web tool focused on locating accounts you know about and rolling them into a partner IRA.

• Beagle — Paid subscription (~$4.99/mo starter; verify on their site) for broader search and concierge-style help.

• Empower — Free personal dashboard app for tracking accounts and planning; not a dedicated lost-401(k) finder.

• National Registry of Unclaimed Retirement Benefits — Free web database; not an app, but a common first stop.

1. Asset Recovery: Lost 401k

Asset Recovery: Lost 401k is built for one calm job: Help you open the right official search paths—Department of Labor Lost and Found, Abandoned Plan Search, and PBGC unclaimed pensions—then stay organized with plain-language claim guidance.

You enter a former employer and years worked; the app never asks for your Social Security number. Searches happen on government sites. Optional partner links (for rollover or planning) stay optional. It’s free to download on the App Store and Google Play.

Best if you want a mobile guide that puts official tools first—not a paid middleman.

2. Empower

Empower (formerly Personal Capital for the dashboard experience) is a polished free app for seeing linked accounts in one place, projecting retirement, and exploring IRA products. It’s excellent for ongoing money clarity.

It is not primarily an orphaned-401(k) locator. Use it once you know what you have—or alongside a finder—rather than as your only discovery tool.

3. Capitalize

Capitalize (web-first) shines when you already know which employer held the plan and you want help with IRA rollover paperwork. For many users, core rollovers into partner IRAs are free; rolling elsewhere may need a paid “Plus” tier (pricing changes—check Capitalize before you decide).

It’s a strong companion after you’ve found the account. It’s less of a “I don’t know where anything is” discovery app than a consolidation helper.

4. Beagle

Beagle markets itself as a fuller search-and-manage service: find old accounts, analyze fees, and get help consolidating. Plans typically start around $4.99/month (confirm current pricing on meetbeagle.com). Some reviews note SSN requirements and subscription billing—read the fine print.

Choose Beagle if you’re comfortable paying for concierge-style search after free government options. Skip it if you only need official links and a simple checklist.

5. National Registry of Unclaimed Retirement Benefits

The National Registry is a free website (not a mobile app) where plans can list unclaimed retirement benefits. Coverage depends on what sponsors submit, so empty results don’t always mean you have nothing.

Treat it as one free stop among several official databases—not a full replacement for DOL, PBGC, or employer HR.

How to choose

If you want apps to find a lost 401k without paying to search, start with a guide that opens official databases—like Asset Recovery: Lost 401k—then use Capitalize or your IRA provider when you’re ready to roll over. Save paid finders for when free paths stall and you understand the subscription.
