What we publish
FinancialRatios.guide is an educational reference. We explain financial ratios and related business measures, show how they are calculated, and provide calculators that work without an account. We publish a page only when it has a checked formula, an original explanation, a worked example and cited sources.
How pages are written and checked
- Formulas come from published sources: open textbooks, accounting standards and regulators. Each page lists its sources.
- Where sources define a measure differently, the page says so and explains the variants.
- Worked examples use round, illustrative figures and are labelled as illustrative. They are not the results of any real company.
- We use software tools, including AI writing assistants, to help draft and check pages. Every formula is checked against its sources and covered by automated tests before it is published. An independent review of every page by a person with appropriate accounting or finance qualifications is under way.
- Pages show a review date only once that review has covered them. We do not invent author or reviewer credentials.
Benchmarks and opinions
We do not publish “ideal” values, industry averages or thresholds unless they come from a sourced dataset whose definitions, period and sample we can describe. We describe what a higher or lower result can indicate, with the context that affects it, instead of labelling results good or bad.
Independence and advertising
The site is supported by display advertising. Advertisers have no say in what we write. Ads never appear inside a calculator, between a result and its formula, or in embedded calculators, and the figures you enter are never shared with advertising or analytics services. If we ever include sponsored content or affiliate links, they will be clearly labelled.
Corrections
If you find an error, please tell us through the contact page, with the page address and what you think is wrong. We check every report. When a correction changes a formula, a result or a substantive statement, we fix the page and re-run the tests for that formula. Formula changes are recorded in the version number of the formula and of the open dataset.
