Sources Policy

FinanceCalcHub uses sources according to the type of claim, the authority of the publisher, the age of the information and whether the source directly supports the explanation being made.

Our preferred source hierarchy

When practical, FinanceCalcHub gives priority to sources closest to the original rule, calculation, procedure or dataset.

1. Official government and regulatory sources, including government agencies, official forms, instructions and published guidance.
2. Primary documentation, such as original regulations, official program material, lender documentation, financial disclosures or technical specifications.
3. Established institutional sources, including recognized educational, professional and nonprofit organizations.
4. High-quality secondary explanations that clearly identify their own sources and accurately summarize the underlying material.
5. Public personal accounts, used only to describe the reported experience and not as authoritative guidance.

Official sources

For U.S. tax topics, official IRS pages, forms and instructions are generally stronger sources than unsourced summaries. For Social Security and Medicare topics, relevant official agency information may be used.

State-specific tax and payroll questions may require state agency sources. Mortgage, lending and consumer finance topics may require federal agency, regulator, lender or official program documentation.

Primary sources and calculation sources

Some calculator explanations depend primarily on mathematical formulas rather than a single external webpage. In these cases, the methodology should identify the formula, inputs, assumptions and limitations clearly enough for the calculation to be understood.

Where a calculator uses an external rate, threshold or rule, the relevant source should be reviewed and updated when necessary.

Secondary sources

Secondary sources may be useful for context, plain-language explanations or comparison. They are evaluated based on editorial quality, transparency, sourcing, relevance and whether the information can be confirmed elsewhere.

A secondary article is not treated as authoritative simply because it ranks highly in search results or is widely repeated.

Public stories, forums and social platforms

A public post may explain what a person says happened, but it does not automatically prove every factual detail. FinanceCalcHub may use public accounts as the starting point for Real Money Stories while separately researching the general financial issue.

Comments from other users are not treated as official tax, legal, payroll, lending or investment guidance.

Source relevance

A credible source must also be relevant. A source about one form, program, state or tax year should not be used to support a broader conclusion that it does not address.

Links should be placed near the claim or in a clearly labeled official-sources section when that structure is more useful to the reader.

Freshness and dates

Financial rules, tax thresholds, agency procedures, interest rates and program requirements can change. Time-sensitive information should be checked for current applicability before it is presented as current.

Older sources may still be appropriate for historical explanations, stable formulas or articles describing a past event, but the context should be clear.

External links

External links are provided to support verification or further reading. FinanceCalcHub does not control external websites and cannot guarantee that a linked page will remain available or unchanged.

Linking to a source does not mean FinanceCalcHub endorses every statement, product, service or policy on that website.

Corrections to sources

Broken, outdated or inappropriate sources may be replaced when an article is reviewed. A material change to the source or underlying rule may also require the article explanation or calculator assumption to be updated.

Readers can report source concerns by emailing contact@financecalchub.com and including the page URL and the affected claim or link.
