Editorial Policy & Methodology
Our goal is to build calculators that are accurate, transparent, and continuously updated. This page explains how we create and maintain our tools, especially for finance and tax topics (YMYL) — while also covering math calculators and unit converters.
1) What VerCalc is (and isn’t)
- VerCalc provides educational tools and estimators. We do not provide legal, tax, or financial advice.
- For complex cases, users should verify results using official guidance or a qualified professional.
2) What kinds of tools we publish
VerCalc includes multiple categories of tools, each with different expectations for sourcing and review:
- Finance & Taxes (YMYL): calculators that estimate money outcomes (refund vs owed, deductions, loan costs, retirement). These require the strongest review and source transparency.
- Health (YMYL): calculators that support wellness planning (e.g., BMI, macros). These require clear limitations and cautious language.
- Math & Statistics: formula-driven calculators (percentages, p-values, number bases). These rely on well-defined mathematical rules and verifiable formulas.
- Converters & Utilities: unit conversions (length, speed, pressure, time). These rely on consistent definitions and standards for units and conversions.
3) Calculation methodology
Each calculator is based on a clearly defined formula or ruleset (e.g., amortization, progressive brackets, statutory thresholds). We prefer:
- industry-standard formulas (e.g., amortization schedules, compound interest),
- authoritative reference data for tax parameters (brackets, deductions, credits),
- explicit edge-case handling (e.g., preventing negative principals, divide-by-zero, invalid ranges).
4) Sources & references
Where a tool depends on definitions or changing parameters, we cite sources on-page when feasible:
- Taxes/finance: authoritative guidance and public institutions (e.g., IRS, consumer protection agencies, central banks).
- Converters: unit definitions and standards bodies where applicable (e.g., measurement standards).
- Math: formulas are presented explicitly so results are independently verifiable.
5) Review & update cadence
- Each calculator includes datePublished and dateModified (and in some cases, review date).
- We update tools when the underlying rules change (e.g., new tax year parameters) and when we identify edge cases that could affect accuracy.
6) Privacy
Calculations are performed locally in the browser whenever possible. We avoid collecting sensitive inputs unless required for core site functionality.
7) Feedback & corrections
If you spot an issue, email us at contact@vercalc.com. Please include the calculator URL and your input/output example.
