What we publish
Each page must answer a specific financial question, state its assumptions, show the relevant formula, and avoid promises about returns, approval, savings, or search rankings.
EDITORIAL & CORRECTIONS
Useful, transparent, and correctable.
Our editorial policy is designed for a calculator site: explain the math, separate facts from estimates, and make errors easy to report and fix.
Review standard
Calculator logic is reviewed against independent formulas and boundary cases. Educational statements should use primary public sources when a definition, rule, or consumer protection claim needs support.
Updates
Evergreen formulas are updated only when the implementation or explanation changes. Pages that mention current rates, fees, or product terms must show a genuine review date and be rechecked before that date is changed.
Corrections
Confirmed calculation errors are prioritized over design changes. A correction should include a regression test, a concise explanation of what changed, and an update to affected examples or documentation.
