The formulas, conventions, and assumptions behind every number Valculator shows.
Not published yet
Written documentation isn't online yet. It isn't hidden, though: every assumption an engine uses — processing fee, GST, stamp duty, legal and valuation costs, the rates behind any illustration — is listed with its source and last-reviewed date inside the product itself, under “View assumptions” on any result.
That's deliberate. The assumptions matter most at the moment you're looking at a number, not in a separate manual.
