How Much Should I Spend on Rent in Australia? — The 30% Rule

The standard benchmark for rent affordability is the 30% rule: housing costs should not exceed 30% of your gross income. Spending more than 30% on rent is considered “rental stress” in Australia.

How the 30% Rule Works

$$\text{Maximum monthly rent} = \frac{\text{Annual gross income} \times 0.30}{12}$$

Examples:

Is the 30% Rule Realistic in Sydney and Melbourne?

In major Australian cities, particularly Sydney, the 30% rule is impossible for many renters on median incomes.

Sydney example:

• Median full-time income: ~$98,000 gross
• 30% of gross = $29,400/year = $565/week
• Median 1BR apartment rent in Sydney: $750–$900/week

This means a person on median income would need to spend 40–50%+ of their gross income on a median Sydney apartment. The 30% threshold is simply not achievable for many Sydney renters without shared accommodation.

Melbourne:

• Median 1BR apartment: $600–$700/week
• 30% of $98,000 = $565/week
• Closer to the threshold but still tight for median earners renting alone

What to Do When Rent Exceeds 30%

If your rent will exceed 30%, options include:

1. Share accommodation — splitting a 2–3 bedroom property with flatmates is the most common solution in Sydney and Melbourne
2. Choose a more affordable suburb — outer suburbs are significantly cheaper; assess the true cost (time + transport cost) of the commute
3. Negotiate rent — in some markets, landlords will accept slightly below asking price, especially for longer leases
4. Increase income — a pay rise, second income source, or career move can improve the ratio
5. Accept the trade-off temporarily — if living in an expensive suburb has career or lifestyle benefits, a period of higher housing cost may be worthwhile, provided you still save something

Should You Use Gross or After-Tax Income?

The traditional 30% rule uses gross income. Some financial planners suggest using after-tax (net) income as a more realistic measure:

$$\text{Alternative: Max rent} = \text{Monthly net income} \times 0.30$$

Example (net income for $80,000 gross, no HECS, FY2025–26): ~$5,300/month net

• 30% of net = $1,590/month = $367/week

This is a stricter measure but more accurately reflects what you can afford in practice.

Rent vs Other Expenses

Beyond the 30% rule, rent affordability also depends on your other fixed costs. If you have:

• HECS repayments ($300–$800+/month)
• Car loan ($500+/month)
• Health insurance ($150+/month)

…then spending 30% on rent leaves very little for savings, discretionary spending, or financial goals.

A more complete picture: total fixed costs (rent + loan repayments + insurance + utilities) should ideally not exceed 50–55% of after-tax income.

Rental Stress in Australia — ABS Data

The ABS defines rental stress as households in the lowest 40% of income who spend more than 30% of gross income on housing. According to ABS data, approximately 1 in 3 renters in Australia is in rental stress — disproportionately affecting low-to-middle income households in major cities.

FAQ

Is 40% of income on rent too much? 40% is above the traditional threshold for rental stress and leaves less room for savings and discretionary spending. It may be manageable short-term if other costs are low and income is growing, but ideally aim to reduce it below 35% through increased income or more affordable accommodation.

Can I ask for a lower rent? Yes — particularly if the property has been listed for a while, if you have a strong rental history, or if you are offering a longer lease. It doesn’t hurt to ask.

Does rent assistance help? Commonwealth Rent Assistance (CRA) is available to eligible Centrelink recipients. As of FY2025–26, the maximum fortnightly payment is approximately $184 for singles. Check the Services Australia website for current rates and eligibility.
