Our commitment: Every calculator on CalcPro is built on verified formulas, reviewed for accuracy by a subject-matter expert, and updated when regulations, rates, or best practices change. We never publish unverified figures and we never accept payment to alter our content.

1. Who Creates Our Content

CalcPro content is developed and reviewed by the CalcPro Editorial Team — specialists in finance, health, mathematics, and everyday practical calculations, working together to verify formula accuracy and methodology before publication.

All calculator logic is implemented by qualified developers and independently verified against at least two reference sources before publication.

2. Our Content Review Process

STEP 01

Formula Research
We identify the authoritative formula from academic or regulatory sources.

STEP 02

Implementation
A developer builds the calculator logic, tested against known benchmark results.

STEP 03

Expert Review
A subject-matter expert independently verifies outputs across a range of inputs, including edge cases.

STEP 04

Content Audit
All accompanying text is fact-checked and reviewed for clarity and accuracy.

STEP 05

Ongoing Review
Pages are reviewed at least annually. Time-sensitive content (tax brackets, rates) is reviewed as soon as changes are announced.

3. Sources and References

CalcPro relies on primary and authoritative sources including:

Where we reference external data (e.g. average interest rates, standard health thresholds), we cite the source in the relevant page or guide.

4. Health and Financial Disclaimers

CalcPro calculators are informational tools. They are not a substitute for professional medical advice, financial planning, or legal counsel. All health-related and financial calculation pages carry a disclaimer to this effect. We encourage users to consult a qualified professional before making decisions based on calculator outputs.

5. Corrections Policy

We take accuracy seriously. If you identify an error in any calculator or piece of content, please contact us with details. We review all corrections reports within 48 hours. If an error is confirmed, we correct it and note the update date on the relevant page. We do not silently edit errors.

6. Commercial Independence

CalcPro is funded by display advertising (Google AdSense). Advertisers have no influence over our calculator formulas, methodology, or written content. We do not accept sponsored content, affiliate payments, or paid reviews. Our editorial decisions are made independently.

7. Update Frequency

Every page displays a "Last Reviewed" date. Calculators involving regulated figures (tax rates, interest rate benchmarks, WHO health thresholds) are reviewed as soon as relevant changes are announced — typically within 5 business days of a regulatory update.
