Methodology, How These Guides Are Written
Every PlainRetire guide is written directly against the U.S. Department of Labor's Form 5500 public disclosure dataset, using the most recent plan year with complete asset-reporting coverage (see each guide's own byline for its exact plan year). When a guide cites a number, such as "Walmart's 401(k) holds $X billion", "15,000 plans in Texas", or "401(k) filings outnumber pensions 8 to 1", that number is computed from the same normalized tables that power the data pages on this site (plans, plan_assets, states, industries). PlainRetire does not publish a standardized all-in fee or participant fee estimate; fee questions belong in the plan's participant disclosure. We do not rely on third-party summaries or press releases for headline figures.
Guides are structured to explain what the underlying Form 5500 fields actually measure, how they are computed by the plan sponsor, and what they do not measure - common pitfalls in interpretation, year-over-year comparability, and the difference between filed data and participant outcomes. Where a guide uses an example plan, the detail page for that plan is linked so readers can verify the numbers against the raw filing.
Scope: U.S. employer-sponsored retirement plans that file Form 5500-401(k), defined benefit pensions, ESOPs, profit-sharing, money-purchase, and IRA-based plans. Out of scope: individual retirement accounts without an employer filing, non-qualified deferred compensation, Social Security, and state-run retirement systems (which file different disclosures).
Primary dataset: U.S. Department of Labor, EBSA Form 5500 public disclosure dataset.
