Annual research tracks rental affordability across Australia and highlights the experiences of disadvantaged households.

The annual rental affordability index (RAI) report is an easy to understand indicator of rental affordability relative to household incomes. It is a crucial tool for policy-makers to track rental affordability trends and inform evidence-based policy responses. The RAI is a valuable tool for quantifying the rental affordability challenge in a way that brings out nuances between places and highlights the experiences of disadvantaged households.

We have partnered with National Shelter, Beyond Bank, and Brotherhood St Laurence on the RAI since 2015.

Background

Studies of housing affordability in Australia have focused primarily on purchase affordability (e.g. housing affordability index) and measuring housing stress at different points in time for different household types. However, a gap existed in tracking rental affordability over time across Australia.

The RAI fills this gap, providing insights into how rental affordability impacts different places and household types. Its basis is customised data and analysis revealing affordability trends in the rental market, with a particular focus on low-income households. Rental affordability concerns a growing and already large proportion of Australians as households increasingly face constraints to purchasing their first house. Renting households on average have lower-incomes, and therefore affordability issues affect renting households more than homeowners.

The RAI method

It is generally accepted that if housing costs exceed 30 per cent of a low income household’s (households with the lowest 40 per cent of income) gross income, then that household is experiencing housing stress (30/40 rule). In the RAI, households who are paying 30 per cent of income on rent have a score of 100, indicating that these households are at the critical threshold for housing stress. A score of 100 or less indicates that households would pay more than 30 per cent of income to access a rental dwelling, meaning they are at risk of experiencing housing stress.

To better illustrate the situation for vulnerable groups, we assess the rental affordability situation for eleven Australian household types. These are:

  • Single person on JobSeeker payment
  • Single pensioner
  • Pensioner couple
  • Single part-time worker parent on benefits
  • Single full-time working parent
  • Single income couple with children
  • Dual income couple with children
  • Student sharehouse
  • Minimum wage couple
  • Hospitality worker

The RAI is calculated using the following equation, where ‘qualifying income’ refers to the household income required to pay rent where rent is equal to 30% of income. RAI = (Median income ⁄ Qualifying Income) x 100

Watch the event recording of the live Q&A event: Rentals, Regions and Rising Prices held on 2 December 2021 that explores the latest rental affordability insights across Australia's local government areas and discuss practical ways local councils can tackle unaffordable housing and support families in need.
