Editorial Policy

Our commitment to accuracy, transparency, and editorial independence.

Our Editorial Standards

Accuracy First

Every calculator uses verified financial formulas based on industry standards. We cross-reference our calculations against established financial institutions and regulatory bodies.

Our Process:

Research industry-standard formulas and methodologies
Implement with unit tests to verify mathematical accuracy
Compare results against established calculator tools
Document all assumptions and limitations

Regular Updates

Quarterly Review Schedule:

January: Update contribution limits, tax brackets, standard deductions
April: Review mortgage and loan calculators, update default rates
July: Audit investment and retirement calculators
October: Review all calculators for accuracy

Each calculator displays its last review date. Emergency updates are made immediately when we discover errors or when major policy changes occur.

Editorial Team

All calculators are created and reviewed by the CalcGrid Editorial Team, which consists of developers with backgrounds in finance, mathematics, and software engineering.

While we are not licensed financial advisors, we follow rigorous standards to ensure our tools are mathematically accurate and based on publicly available financial formulas.

Independence & Transparency

No Conflicts of Interest: We do not accept payment from financial institutions to promote specific products. Our calculator results are not influenced by advertising or partnerships.

Clear Limitations: Every calculator clearly states its assumptions and limitations. We do not overstate capabilities or make guarantees about accuracy.

Open to Feedback: If you find an error or have suggestions, please contact us. We investigate all reports and make corrections when warranted.

Our Data Sources

We reference authoritative sources for our default values and formulas:

IRS: Tax brackets, contribution limits, deduction amounts
Federal Reserve: Interest rate data
Bureau of Labor Statistics: Inflation data
CFPB: Consumer financial formulas and guidelines
Freddie Mac: Mortgage rate averages

Specific sources are cited on individual calculator pages where applicable.

Corrections Policy

We take accuracy seriously. If we discover an error or receive a credible report of one, we:

Investigate the issue immediately
Correct the error if confirmed
Update the "last reviewed" date
Document the change in our internal version history
