The 30% rule explained

The 30% rule originated in US federal housing policy in the 1980s and was adopted internationally as a rule of thumb for housing affordability. In Australia, the National Housing Supply Council and AIHW use 30% of gross income as the threshold above which households are considered housing cost stressed.

The limitation: 30% of gross income at $50,000 ($288/week) leaves very little after tax in many Australian cities. 30% of gross income at $200,000 ($1,154/week) leaves far more than needed. The rule works better as a ceiling than a target.

A more practical approach: calculate 30% of your after-tax income using our income tax calculator, then subtract other essential expenses.

Frequently asked questions

The 30% rule states that housing costs (rent) should not exceed 30% of gross income. It's widely used by landlords, letting agents, and financial advisers as a quick affordability benchmark. Households spending more than 30% on rent are considered 'housing cost stressed' by the Australian government. Note: the rule uses gross (pre-tax) income, meaning the after-tax impact is larger.
In Sydney and Melbourne, median rents often exceed 30% of median income — meaning many renters are technically housing-stressed. Sydney median unit rent of ~$580/week requires approximately $100,000 annual income to stay within 30%. This is why many Australians share housing or live further from city centres.
Most landlords and property managers assess applications using the 30% rule: annual rent should not exceed 30% of gross annual income. They may also check employment history, rental references, and credit history. Some use a more conservative 25% threshold for higher-certainty tenants.
The 30% rule traditionally uses gross (pre-tax) income. However, using net (after-tax) income gives a more realistic picture of your actual budget. On $75,000 gross, your take-home is approximately $59,000 — meaning a 30%-of-gross rent of $22,500/year ($1,875/month) represents about 38% of your actual take-home pay.
