Editorial Policy

Why this page exists
Worth101 publishes financial calculators and educational content in Google's Your-Money-or-Your-Life (YMYL) category. This page documents how we produce that content so you can judge its trustworthiness. Editorial independence is covered separately on our Disclosures page.
1. Data sources
Assumptions and limits come from primary, public-domain references: the IRS (contribution limits), the Social Security Administration (benefit and full-retirement-age rules), the Bureau of Labor Statistics (CPI / inflation), the Federal Reserve, and HealthCare.gov / Medicare.gov for healthcare assumptions. Each tool maintains a single assumptions registry so every page cites the same numbers.
2. Review workflow
Calculator math is centralized in shared, unit-tested logic and pinned by regression tests before release. Tool and methodology pages carry a visible "Last reviewed" date and an assumptions changelog. When a formula or assumption changes, the registry, the methodology page, and the changelog are updated together.
3. Keeping figures current
Tax-year-dependent values (for example, 401(k) and IRA contribution limits) are updated annually from the IRS once new figures are published, and the content year is bumped in the registry. Numbers shown in narrative text are generated from the registry rather than typed by hand, so a single update propagates everywhere and prevents stale values.
4. Not financial advice
Worth101 is educational. Our calculators are deterministic projections based on the assumptions you enter; they are not predictions and do not account for every personal circumstance. We are not licensed advisors. Always consult a licensed fiduciary before making investment, tax, or retirement decisions.
5. Corrections
If you spot an error in a formula, a cited limit, or a factual claim, tell us and we will verify against the primary source and correct it, updating the review date on the affected page.
