Formula selection
CalcPilot uses standard, widely recognized definitions for each calculator and states the exact formula on the page. When a metric has multiple valid definitions—such as margin, churn, CAC, or engagement rate—we name the version being calculated and explain the scope choices that affect comparisons.
Calculation testing
Every live formula is implemented as a pure TypeScript function and tested during the static build with representative values, zero-denominator protection, and relevant boundary rules. Worked examples are calculated independently from the defaults and kept visible so readers can reproduce the result.
Editorial standards
Explanations are written for practical decision-making. We distinguish what a metric proves from what it merely suggests, identify common definition errors, and link related metrics that provide necessary context. We do not publish fabricated benchmarks or imply that one threshold fits every industry.
Review and corrections
Pages display their latest review date. We review formulas when standards, platform definitions, or common reporting practices change. To report a potential error, email hello@calc-pilot.com with the URL, expected result, and source.
Limitations
Calculators simplify reality. Results depend on input quality and may exclude taxes, timing, risk, accounting policy, law, or personal circumstances. CalcPilot provides educational estimates, not individualized financial, legal, tax, investment, or accounting advice.
