What the widget does and does not do

It runs the same calculation as our full tool pages, with the same official sources.
It sets no cookies and stores nothing in the visitor's browser.
We count widget loads as one anonymous total per calculator per day. We do not record the website it is on, the visitor's address or anything they type.
You can pre-fill a value, for example ?price=350000 at the end of the address.

By using the code you agree to the widget terms.
