Financial Source and Review Standards

Our source hierarchy

1. Primary government and regulator sources: agencies responsible for consumer rules, tax limits, housing programs, deposit insurance, securities education, or benefit administration.
2. Official program administrators: sources that operate or administer the program being discussed.
3. Public-interest education: noncommercial resources designed to improve consumer understanding.
4. Secondary explanation: used only when it adds clarity and does not override a primary source.

How authoritative backfill works

Older high-value pages are reviewed in topic groups. We add direct source links, a visible review date, author or reviewer information, methodology links, clearer assumptions, and warnings where estimates can differ from real-world offers or outcomes.

Backfill is prioritized for pages involving debt, credit, mortgages, emergency savings, retirement, investing, and family cash flow. Thin or repetitive pages are not strengthened merely to increase page count; they may remain excluded from search indexing.

Calculator standards

• Inputs and assumptions should be understandable without professional software.
• Outputs are estimates, not approvals, quotes, guarantees, or personalized advice.
• Annual limits and changing rules are dated and reviewed against the responsible agency.
• Related guides explain tradeoffs the calculator cannot measure.
• Material corrections are handled under the corrections policy.
