Transparency & Trust
Editorial Standards & Methodology
How we ensure every calculator produces accurate, trustworthy results — and how we maintain editorial independence from advertisers.
Our Core Commitment
WealthCalc provides free financial calculators and educational guides for informational purposes. We do not sell financial products, receive commissions for calculator recommendations, or allow advertisers to influence our formulas or editorial content. Every number you see in a WealthCalc calculator is derived from a publicly verifiable government source — not estimated, rounded, or adjusted for marketing purposes.
We are funded by display advertising (Google AdSense). Ads are served based on your browsing context and are clearly separated from editorial content. No advertiser has ever reviewed, influenced, or approved any calculator methodology, article, or FAQ on this site.
About the Author
Tahir Özcan
Founder & Lead Author · WealthCalc
Tahir is a software engineer and personal-finance researcher who built WealthCalc after spending a decade modeling household budgets, retirement plans, and mortgage scenarios for family, friends, and community members. Frustrated by financial tools that obscured their formulas behind paywalls or produced inconsistent results, he built a fully transparent, open-source calculator suite grounded in primary government data.
Tahir reads every relevant IRS Revenue Procedure, SSA COLA announcement, and FHFA limit release directly. He cross-validates calculator logic against the CFA Institute curriculum and tests edge cases before each release. His background in software engineering means the code itself is reviewable on GitHub — nothing is hidden.

Our 5-Step Review Process
1
Primary Source Research
Every calculator parameter (tax brackets, contribution limits, rate caps) is sourced directly from the relevant government agency — IRS, SSA, FHFA, BLS, or Federal Reserve. We do not use third-party aggregators as a primary source.
2
Formula Validation
Financial formulas are cross-validated against two independent references: the primary government publication and the CFA Institute curriculum. For mortgage and loan calculations, we verify against amortization schedules produced by established financial software.
3
Edge Case Testing
Each calculator is tested across 20+ input combinations including boundary conditions: zero down payment, interest-only periods, Roth vs Traditional conversions, filing status changes, and corner cases that reveal formula errors.
4
Annual Update Protocol
Within 48 hours of any IRS Revenue Procedure, SSA COLA announcement, or FHFA limit release, we update all affected calculators. The current data version is 2026 (updated January 2026).
5
Reader Feedback Loop
Users can report discrepancies via our contact form. Reported issues are investigated within 72 hours and corrected within 7 days if validated against primary sources.

Advertising & Independence Policy
Display advertising: WealthCalc uses Google AdSense to display contextual ads. Ads are clearly labeled and are not editorial content. AdSense placement decisions are made by Google's automated system — not by WealthCalc editorial staff.
No affiliate commissions: We do not receive referral fees for calculator results or tool recommendations. When we link to external resources, those links are educational — not monetized.
Advertiser separation: No advertiser has ever requested, reviewed, or influenced any calculator formula, FAQ answer, or article on this site. Our editorial decisions are 100% independent of advertising revenue.
Not financial advice: Calculators produce estimates based on inputs you provide. Results are for educational planning purposes only. Always consult a qualified financial advisor (CFP), tax professional (CPA), or attorney before making major financial decisions.
Corrections & Feedback
If you believe a calculator contains an error, produces an unexpected result, or references outdated data, please report it. We investigate all reports within 72 hours and publish corrections within 7 days if validated.
