How We Build Calculators

Each calculator runs in the browser, uses documented formulas, and is checked against representative scenarios before release.

Each calculator keeps its core formula visible or explained on the page.
Calculations run locally in the browser, so users can test scenarios without creating an account.
We spot-check representative examples, edge cases, and rounding behavior before major updates.

How the English Public Edition Works

We publish a single English public edition so formulas, examples, policy pages, and review notes stay aligned in one version that is easier to audit and maintain.

We update the English source version first and review that edition before anything becomes public.
The public site currently serves English pages only so formulas, guidance text, and structured data stay in one audited release.
Internal localization files can still support future editorial work without publishing additional language editions prematurely.
