Editorial publication standard
A calculator must answer a real financial question, expose its formula, define inputs, include a worked example, identify limitations, cite appropriate evidence and connect to the next useful calculation.
Independence
Advertisers, affiliates, lenders, brokers and financial products cannot alter formulas or results. Free Calculators Online does not rank or recommend products in calculator outputs.
High-stakes boundaries
Tax, investment, retirement, credit, lending and health outputs are educational estimates. We avoid individualized recommendations and direct users to official disclosures or a qualified professional, including a physician for any health or clinical output, when personal facts determine the answer.
Use of automation
Automation may assist organization, testing and drafting. But it is never cited as evidence. Material current-year claims require traceable primary sources.
Correction priority
A defect changing an output is critical. An ambiguous definition is high priority. Stale contextual information is reviewed according to the decision risk it creates.
No product recommendations, ever
Calculators return arithmetic, not advice. No output ranks a lender, insurer, broker or product, and no page presents a commercial option as the recommended choice. Where a decision genuinely depends on a product's terms, the page directs the reader to the actual disclosure instead of substituting a modelled figure for it.
Sources support definitions, not outcomes
A cited source establishes what a term means, what a rule requires or what an official figure is. It never establishes that a calculated result is correct for your situation. Citations are not used to imply endorsement by the cited body. Every calculator page states explicitly that Free Calculators Online is independent of the organisations it cites.
What gets published and what does not
A calculator is published when it answers a real financial question, exposes its formula, defines every input, produces a worked example, states its limitations, cites appropriate evidence and connects to the next useful calculation. A calculator that cannot meet all seven is not published in a reduced form. It is not published.
Corrections are visible, not silent
When a formula, figure or interpretation is wrong, the fix is applied to the page and its review date moves. Corrections are not made quietly to avoid drawing attention to an error, because a publisher that hides its corrections is asking readers to trust a record they cannot inspect.
Conflicts and independence
No advertiser, affiliate, lender or product provider can alter a formula, a result, an interpretation or a source. There is no paid placement in any calculator output or ranking anywhere on the site.

Frequently asked questions
What must a calculator have to be published?
Seven conditions together: it answers a real financial question, exposes its formula, defines every input, produces a worked example, states its limitations, cites appropriate evidence and connects to the next useful calculation.
What happens to a calculator that meets only some of the seven?
A calculator that meets only some of the seven conditions is not published in a reduced form: it stays unpublished until all seven are met.
Can advertisers, affiliates or lenders change a result?
No. Advertisers, affiliates, lenders, brokers and financial products cannot alter a formula, a result, an interpretation or a source. Nobody can pay to change a result.
Do any calculators recommend a product?
No. Calculators return arithmetic, not advice. No output ranks a lender, insurer, broker or product, and where a decision depends on a product's terms the page points to the actual disclosure instead of modelling a stand-in figure.
Are the results financial advice?
No. Tax, investment, retirement, credit, lending and health outputs are educational estimates. The site avoids individualized recommendations and points to official disclosures, or a qualified professional including a physician for health outputs, when personal facts decide the answer.
Is automation used, and is it treated as evidence?
Automation may assist organization, testing and drafting. Automation is never cited as evidence. Material current-year claims require traceable primary sources.
What does a cited source prove?
A cited source establishes what a term means, what a rule requires or what an official figure is. A source never establishes that a calculated result is correct for your situation, and a citation does not imply endorsement by the cited body.
How are corrections prioritised and shown?
A defect that changes an output is critical, an ambiguous definition is high priority, and stale contextual information is reviewed by the decision risk it creates. Corrections are applied visibly, with the review date moved, never quietly.
