Our 4-Pillar Editorial Standards
- Empirical Source Verification: All baseline unit metrics must be directly traceable to published federal datasets (BLS, EIA, IRS) or verified industry cost indexes (RSMeans). We do not accept unverified marketing claims.
- Subject-Matter Expert Review: Every calculator is assigned to a credentialed reviewer (CPE for construction, CFP for loans and finance, CEM for HVAC/solar, ASE for auto/insurance, CPA for commercial tax).
- Deterministic Calculation Precision: Worksheet logic is executed client-side with full formula transparency so readers can verify calculations independently.
- Strict Commercial Independence: We do not accept sponsored calculator results, pay-for-placement contractor listings, or affiliate lending kickbacks.
Separation of Content and Advertising
SmartCostGuide.org is supported by contextual display advertising provided by Google AdSense. Advertisers have zero influence over our calculator assumptions, regional multipliers, tier factors, or editorial reviews. All advertising units are distinctly rendered and separated from editorial worksheets.
Correction & Rate Update Policy
We take factual precision seriously. If you identify a regional rate discrepancy, an outdated statutory tax limit, or an inaccurate assumption in any worksheet:
- Email our editorial desk at [email protected] with the subject line "Rate Update / Correction Request".
- Please include the specific calculator URL and supporting documentation (e.g., local supplier catalog, municipal permit schedule, or contractor quote).
- Our reviewing analyst will investigate within 48 business hours and publish immediate corrections if substantiated.
