say hi.

flag a bug, dispute a number, ask a question, share your verdict screenshot. anything other than financial advice (we don’t do that).

what to send

  • bugs — broken page, weird verdict, busted share link. include the URL if you can; that encodes everything we need to reproduce.
  • data disputes— think a suburb median is wrong? send a link to the source (ABS, RBA, Domain, PropTrack) and we’ll update.
  • press / media— happy to chat about the model, the data, or what we’re seeing across regions.
  • just yelling — also fine. the housing market deserves it.

what we can't help with

we can’t give you financial, legal, or mortgage advice. this is a public estimator, not a regulated service. for actual numbers tailored to your situation, talk to a licensed mortgage broker, financial adviser, or your lender.

we also can’t look up your specific scenario for you — every input is in the URL, so the calculator does that job in your browser.

privacy

your email lands in a project inbox. we don’t add you to any list, sell anything, or share what you write with third parties. for the full story see the privacy policy.

how this is calculated

we project your savings forward using the dollar amount you save each month. at the same time, the deposit target — 20% of the suburb median, or 5% if you’re using the first home guarantee — grows at the suburb’s historical annual growth rate, compounded monthly.

the crossover is the first month your savings reach or exceed the deposit target. if the deposit grows faster than you can save, you’ll see “never”— and that’s not a bug. that’s the point.
