What we publish, and why
Finzcore publishes two kinds of content: calculators, which run standard financial formulas in your browser, and guides, which explain how a piece of US personal finance actually works — retirement accounts, credit, debt, mortgages, taxes, insurance. The test every guide has to pass is simple: after reading it, could you make the decision it covers without needing a glossary or a second article?
We do not publish news, hot takes, product roundups or sponsored recommendations. Nothing on this site is paid for by a bank, broker, card issuer or lender, and no company reviews our content before it goes live.
How a guide gets written
- Rules come from primary sources. Anything that depends on law or regulation — contribution limits, tax treatment, what a debt collector may do, how credit freezes work — is checked against the primary source: the IRS, the Consumer Financial Protection Bureau, the Social Security Administration, the Federal Reserve, or the text of the relevant law. Where a guide leans on one of these, it links to it.
- Arithmetic is computed, not quoted. When a guide says a balance takes 23 years to pay off at the minimum, that number comes from running the amortization — the same code as the calculator next to it — not from copying another site.
- Examples are worked in dollars. Abstract advice ("pay yourself first") is cheap. Every guide tries to show the actual numbers for a concrete case, so you can substitute your own.
- Plain English is a requirement, not a style. If a term can't be avoided (escrow, PMI, RMD), the guide defines it the first time it appears.
Dates, updates and stale numbers
Every guide shows its publication date, and its modified date changes only when the content meaningfully changes — not when we touch the site's design. Figures that change on a schedule (contribution limits, tax brackets, standard deductions) are tracked internally with the date they go stale, and reviewed when they do. If you are reading a guide in a later year than its date, the mechanics will still be right; double-check any specific dollar limit against the linked primary source.
Corrections
If we got a number, a rule or a conclusion wrong, we want to know: tell us here. Confirmed errors are fixed in the article itself, the modified date is updated, and material corrections are noted in the text. We would rather look wrong for a day than stay wrong quietly.
What this site is not
Finzcore is educational. We are not a bank, a broker or a licensed adviser, and nothing here is personalized financial, legal, tax or investment advice. The guides explain how things work; whether a specific move is right for you depends on facts we don't have. For decisions with real stakes, talk to a licensed professional.
Advertising
The site may show ads in the future. If it does, ads will be visually distinct from content, will never influence what a guide says, and no advertiser will be able to buy a recommendation. The calculators will stay free, with no account and no paywall.
