Why use this calculator
Rental stress — spending more than 30% of income on rent — affects millions of Australians. This calculator shows what you can genuinely afford, what you need saved for move-in, and where you sit relative to the rental stress threshold.
How to use it
Enter your income and pay period (the calculator converts everything to monthly). Add your other fixed monthly expenses. Results show your maximum affordable rent under multiple benchmarks and your total move-in costs.
The formula
Max Rent (gross) = Monthly Gross × 30%. Max Rent (net) = Monthly Take-Home × 30%. Move-In = Bond + 2 Weeks Advance + Miscellaneous (~$500).
Worked examples
$75k annual income, $600/month other expenses, 4-week bond
Max rent ~$1,875/month ($433/week), move-in costs ~$4,700
$50k annual income, minimal other expenses
Max rent ~$1,250/month ($288/week) — very tight in major Australian cities
When people use it
- Checking if you can afford a specific rental
- Planning your move-in savings
- Comparing rental options against your income
- Calculating how much to save before moving out of home
Tips
- The 30% rule uses gross income — the net income measure is more realistic as it accounts for tax
- In Sydney and Melbourne, many renters spend 35-45% of income on rent — this is rental stress territory
- Having 3 months of rent saved before searching gives you a financial buffer
- Factor in utility costs ($200-400/month) when comparing total housing costs
- A housemate can cut rental costs dramatically — a $2,400/month property split two ways = $1,200 each
Questions people ask
- What is the 30% rule for rent?
- The 30% rule suggests spending no more than 30% of gross income on housing. Spending above 30% is considered rental or housing stress and leaves less money for other essentials, savings, and emergencies.
- How much bond do I need to pay in Australia?
- Bond is typically 4 weeks rent in most Australian states. It's held by the state tenancy authority and refunded at lease end minus any legitimate deductions. Two weeks advance rent is also usually required on move-in day.
- What is rental stress?
- Rental stress occurs when a household spends more than 30% of gross income on rent. In Australian cities, this affects a large proportion of low-to-moderate income renters who often spend 40-60% of income on housing.
