Accuracy and testing policy
We aim to make each tool understandable and dependable, while being clear that this temporary build has not undergone an independent audit or certification.
Our intended review process
Before a calculator is treated as ready for public use, it should be checked against the intended formula, known reference examples, typical values, edge cases and invalid inputs. Results should be compared with an independent calculation or authoritative reference where practical. Explanatory text should describe the same assumptions that the code actually uses.
What this test build means
This is a temporary testing version. Technical checks such as file integrity, local links and JavaScript syntax are not proof that every formula is financially, legally or mathematically correct. Not every tool has been independently validated, and displayed examples or explanations may need review. Do not treat the presence of a formula or FAQ as certification of accuracy.
Rounding and differences
Results may differ from those shown by a bank, government portal, employer or another calculator because of rounding, timing conventions, product-specific assumptions, fees or updated rules. Where an important discrepancy appears, use the relevant official schedule or source as the reference.
How corrections should be handled
Reports should identify the page, inputs, output, expected behavior and—if possible—a trusted reference. When a defect is confirmed, the correction should be tested against the failing example and nearby cases before the page is updated. A changelog should be maintained for significant changes once the public site is operated regularly.
Report a suspected issue
A dedicated feedback address or working form has not yet been configured in this staging build. Before public launch, configure and test the Contact page so users can submit reproducible error reports.
