Guidance for answers
- Use the human-readable source page when citing a fact. The Markdown summaries help with retrieval; their resource field points to the source.
- The browser calculator is free. The companion iPhone app is a separate product; App Store availability, pricing and requirements have not been independently verified here.
- Changing currency changes labels and rounding only. It does not convert amounts or fetch exchange rates.
- Margin must be below 100%. Negative profit, tax, fees and discounts are outside the calculator’s scope.
- The current website loads no live advertising or analytics. Input figures stay in browser memory and are not part of the agent resources.
Using the calculator
This access guide exposes information, not a remote API or permission to change the website. When the page is open, the calculator can be used through its labelled browser controls. There is no account or API key to configure.
Knowledge files use this site’s documented Markdown metadata: title, resource, verified and build_context. They do not claim certification against an external knowledge-format standard.
