Editorial Policy

Accuracy and testing

Every calculator is backed by golden test cases — known inputs with independently verified expected results. A calculator cannot be published or updated unless its formula reproduces those results within a strict tolerance.

The computation that runs in your browser is the same code that passes our tests. There is no separate, untested implementation, so the tested math and the shipped math cannot drift apart.

Editorial review

Each calculator names the editor responsible for it. Before a calculator is published or changed, the editor checks that the formula, assumptions, and explanatory content are correct and not misleading.

Review is about methodology, not endorsement of any product or provider. CalcDomain does not recommend specific lenders, funds, or financial products.

Data sourcing

Benchmark figures come from official publishers such as the Federal Reserve, the Bureau of Labor Statistics, and the FDIC. Each dataset records its source, the date the data applies to, and when it was retrieved.

Figures are stored as dated snapshots and updated on a defined schedule. A page always shows the date attached to each figure so you can judge how current it is.

Corrections

If you find an error, contact us and we will investigate promptly. Confirmed errors are corrected and the affected page's update date is changed to reflect the revision.

Material corrections to a formula or a key figure are made as soon as they are verified, not held for a scheduled release.

Independence

CalcDomain's calculations and explanations are not influenced by advertisers or third parties. Where advertising or affiliate links appear in the future, they will be clearly labelled and kept separate from editorial content.
