Open calculatorA clear model behind every result
US and Canadian mortgages are modeled separately. Currency labels are explicit, and each calculator explains its compounding convention and what the estimate leaves out. Examples use illustrative rates, not live offers.
The result opens on a separate page with a schedule and genuine Excel and PDF downloads. Calculations run in your browser; this is an independent tool collection, not a lender or a loan application.
Your scenario stays in your tab
The amounts you enter are kept in this tab’s session storage so the result page can read them. Scenarios expire after 24 hours, and the calculator does not send these amounts to a server or place them in a URL. Download files are created on your device.
The hosting server receives ordinary page requests, which can include IP address, browser information and requested paths in operational logs. No account, payment details or application documents are requested. This initial release has no analytics or advertising integration.
