Editorial policy
Finance content is YMYL. Every calculator must show the maths, cite the rule and state its limits. We do not ship twin pages for the same search intent.
We do not write “loan approved”, “Brazil’s best rate” or CTAs dressed as search results.
Rule corrections outrank new pages. If a rate changes, the calculation core is updated before any acquisition copy.
What we check before publishing
Every calculator or guide must do four things: point to the rule behind it, show the formula in plain language, include at least one worked example and state what the tool does not cover. Worked examples are checked against the same code that runs in the calculators, so text and tool cannot drift apart.
The date of the last check appears on pages and in the footer. When an ordinance, law or resolution changes, the rules file is updated first and the text afterwards.
What we do not do
We do not rank banks, recommend lenders or use wording that suggests approved credit or a guaranteed rate. We do not use urgency triggers such as “last hours” or “exclusive offer”, and we do not publish testimonials or ratings that do not exist.
Results are educational estimates. They do not replace an accountant, a lawyer, your payslip, your contract or a lender’s assessment.
Corrections and independence
If you find an error, use the contact page with the page, the inputs and the passage of the official source. Rule corrections take priority over new pages, and relevant changes update the site’s date.
CalculaBR is independent of banks and public bodies. As of this update the site shows no ads and no affiliate links; if that changes, sponsored content will be labelled and this policy updated first.
