Sources & Methodology

Financial Intelligence Lab uses public educational sources, visible assumptions, and plain-language formulas to support its educational tools. The site is a prototype, so source support needs final review before publication.

Source standard

  • Use public sources when possible.
  • Use government sources for official data.
  • Use educational or nonprofit sources for concepts.
  • Use plain-language explanations near formulas and assumptions.
  • Complete manual review before publishing source-dependent claims.
  • Do not use live data unless a page clearly states that it does.

Candidate public source categories

  • Consumer Financial Protection Bureau consumer education
  • U.S. Bureau of Labor Statistics CPI/inflation resources
  • Federal Student Aid student loan repayment resources
  • IRS tax withholding resources
  • Investor.gov compound interest and investing education
  • University or nonprofit financial education resources
  • Federal Reserve economic education resources, if useful

These categories are source-planning areas, not final citations. Final publication should use reviewed source links only.

Methodology standards

Each calculator should show its core inputs, outputs, formula in plain English, assumptions, limitations, and learning goal. When a tool uses a simplified model, the page should make that simplification visible near the result.

Assumption standards

Assumptions should be visible near outputs, written in plain language, and easy to change. Example assumptions are educational context only. They are not forecasts, predictions, or recommendations.

AI-use standards

AI can support drafting, summarization, and prototyping. Final content should be reviewed by humans for accuracy, clarity, source quality, and the education-only boundary before publication.

Review status

The current site is a working MVP prototype. Calculations, copy, accessibility, and source support should be reviewed again before any production launch or public promotion.

Error reporting and feedback

Users are invited to report unclear assumptions, outdated information, broken links, confusing language, or possible accuracy issues through the Feedback page.
