How is the salary needed calculated?
The salary needed uses the 30% rule: annual income required = (weekly rent x 52) / 0.3. This is a widely used affordability benchmark — spending more than 30% of gross income on rent is considered "rental stress".
Where does the rent data come from?
Rent data comes from government bond lodgement records — NSW DCJ, QLD RTA, and VIC DFFH. This covers actual bonds lodged, making it one of the most reliable rent data sources in Australia.
