About SweatyOpossum

SweatyOpossum began as a personal-finance hobby site and has grown into a free, independent learning center for investing and personal finance. The name stayed; the mission matured: Financial education, made clear.

Our mission

Financial literacy shouldn't require a finance degree, a subscription, or a sales pitch. We publish plain-English lessons, define every term we use, show the arithmetic behind every claim, and link to primary sources — so readers can verify rather than trust. We sell no products, run no ads for financial services, earn no commissions, and take no payment from any company mentioned in our examples.

What we are — and are not

We are an educational publisher. We are not investment advisers, broker-dealers, accountants, or lawyers, and nothing on this site is financial, investment, tax, or legal advice. We never make personalized recommendations, and reading this site creates no advisor–client relationship of any kind. Details are in our full disclaimer.

Editorial standards

• Educational purpose. Every page exists to explain, not to persuade. We describe what investors commonly do and what evidence shows; we do not tell readers what to do.
• No recommendations. We never recommend specific securities, funds, or products. Where a real security appears (for example, in a historical chart), it is a clearly labeled illustrative or historical reference.
• Hypotheticals labeled. Worked examples and calculator outputs are hypothetical illustrations with stated assumptions. Past performance never guarantees future results, and we say so wherever performance appears.
• Primary sources. Claims cite or link to authoritative sources — the SEC's Investor.gov, FINRA, the CFPB, Federal Reserve data (FRED), the IRS, and published academic research.
• Review dates. Every article displays a “Last reviewed” date. Content is re-reviewed periodically and when rules change materially; the site-wide review date appears in the footer. U.S. tax and account rules change often — verify current figures at IRS.gov.
• Corrections. If you find an error, email info.transformly@gmail.com. We correct mistakes promptly and note material corrections on the affected page.

How content is written

Lessons are drafted against a curriculum plan, checked against the primary sources above, and edited for plain language: jargon defined on first use, numbers shown with their arithmetic, and uncertainty stated rather than smoothed over. Each article carries key takeaways, a worked numeric example, common misconceptions, and a short quiz — a structure chosen to teach, not to rank in search results.

The tools

Our calculators and data explorers follow the same rules as the writing: assumptions are labeled and editable, projections carry the hypothetical-illustration caveat, and market data displays name their sources and note that data may be delayed. Market data comes from public sources (Stooq historical prices; FRED) and is informational only.
