Editorial Policy

How we build, verify, and maintain every calculator on CalcWolf. Last reviewed April 2026.

Our commitment

CalcWolf exists to give people accurate, up-to-date financial and lifestyle calculators — not to generate pageviews with thin content. Every number this site outputs affects real decisions: how much house someone can afford, whether a business investment makes sense, what a person actually needs to retire. We take that seriously.

Every calculator on CalcWolf is built from primary sources, tested against independent references, and explained in plain language. When we're uncertain about a formula's applicability to an edge case, we say so.

Our AI policy

📋 AI Use Disclosure

We use AI to assist in drafting article content and explanatory text. All mathematical formulas are manually verified by our team against official primary sources (IRS publications, peer-reviewed research, government actuarial tables, and industry standards). Every calculator undergoes a 3-step quality check before going live. AI-assisted content is reviewed for factual accuracy before publication. We never publish AI output without human review.

The 3-step quality process

Primary Source Research

Every formula is traced to its official origin. Tax calculations reference IRS Rev. Proc. publications. Health formulas cite peer-reviewed research (e.g., Mifflin-St Jeor 1990 for BMR). Financial formulas reference standard actuarial and banking publications. The source is linked directly on the calculator page.

Cross-Verification Against References

Results are tested against at least two independent reference calculators — government tools, established financial institutions (Bankrate, NerdWallet, IRS withholding calculator), or academic reference implementations. We test a range of inputs including edge cases (zero values, maximum inputs, historical extremes) to catch formula errors that only appear in specific ranges.

Plain-Language Review

The accompanying article must accurately explain the formula, state its assumptions, and acknowledge where it may produce misleading results for edge cases. A calculator that gives a number without context is not useful — we hold our explanations to the same standard as the math.

Content update policy

Rate-sensitive calculators (tax brackets, mortgage rates, AI model pricing) are reviewed when official sources publish changes — typically annually for tax data, and on an ongoing basis for rapidly-changing categories like AI pricing. Each calculator page displays its last-reviewed date.

When a calculator is updated, the "Updated [Month Year]" timestamp on the page reflects the date of the most recent formula or rate revision, not just a content edit.

Reporting errors

Every calculator page has a Report an Error button. Error reports are reviewed by Kevin Glover personally. If you report an incorrect formula or outdated data with a specific input example, you'll get a response within 48 hours and the fix will be deployed with the next build.

We believe offering a clear error-reporting channel is a sign of commitment to accuracy, not a sign of weakness. No calculator is perfect on day one — sustained accuracy requires a feedback loop.

What we don't do

We don't accept payment to feature, promote, or positively bias any financial product, service, or company.
We don't use affiliate tracking that could create incentives to steer users toward particular products.
We don't publish calculators that we cannot verify against primary sources.
We don't treat AI-generated content as publication-ready without human editorial review.
