Calculator Review Process
Before any calculator is published on CalculatorPanda, it undergoes the following review process:
Formula Verification
The underlying formula is verified against authoritative sources and cross-checked with established industry tools.
Edge Case Testing
We test calculators with known inputs (including edge cases) to verify outputs are mathematically correct.
Expert Review
Finance calculators are reviewed by qualified financial professionals. Health calculators are reviewed against established clinical guidelines.
User Testing
We test usability across desktop and mobile devices before publication.
Update & Review Schedule
Calculators that rely on frequently changing data (tax rates, lending rates, health guidelines) are reviewed and updated at least annually or whenever significant changes to source data are published. Each calculator page displays a "Last reviewed" date so users can assess freshness.
Advertiser Independence
Advertisers and affiliate partners have no influence over our editorial content, calculator formulas, or results. Our commitment to accuracy is never compromised by commercial relationships. See our Disclaimer for details on affiliate disclosures.
