The usual benchmark is 30% of gross income, but you pay rent from take-home pay. Here is how to check a rent against what lands in your account each fortnight, and what to have ready before you move in.

Money Detective is built around practical household money tools for Australians.
A common rule of thumb is to keep rent under 30% of your gross income. Because you pay rent from take-home pay, it is safer to also check it against the money that lands in your account each fortnight. On a $3,270 gross and $2,600 take-home fortnight, rent of $1,000 a fortnight is about 31% of gross, but about 38% of what you actually have to spend. That gap is why a rent can look fine on paper and feel tight on payday.
Australian housing researchers and agencies use "housing stress" or "rental stress" to describe households that spend more than 30% of gross income on housing. The AIHW's housing affordability page explains that it is most often used for lower-income households, and notes that higher-income households may choose to spend more. It is a measure used for statistics, not a personal rule, and it does not know your other bills, your kids or your debts.
Look at your payslip for one pay. Write down your gross pay and your take-home pay. The gap is tax and anything else deducted. The 30% rule uses the first, and your budget lives on the second.
Rent is usually advertised per week. If you are paid fortnightly, multiply by 2. If rent is monthly, multiply by 12 and divide by 26.
| Weekly rent | Per fortnight | Share of gross | Share of take-home | Left from take-home |
|---|---|---|---|---|
| $450 | $900 | 28% | 35% | $1,700 |
| $500 | $1,000 | 31% | 38% | $1,600 |
| $550 | $1,100 | 34% | 42% | $1,500 |
At $500 a week, this household is just over the 30% mark on gross income. The more useful number is the last column: $1,600 left to cover everything else for the fortnight, including groceries, utilities, transport and any debts.
Rent is only one fixed cost. Add up everything else that has to come out before your next payday, such as utilities, phone, car costs, insurance and debt repayments, and take it from what is left. That is what you really have to live on. The safe to spend guide explains the idea, and the free Payday Check estimates it from your balance, rent and bills. There is no sign-up and no bank connection.
Moving costs more than the first week of rent. The two big items are the bond and rent in advance. The bond is usually up to four weeks of rent, and many landlords ask for the first two weeks in advance, but the rules differ by state and by the weekly rent, so check your state's tenancy authority. In Queensland, for example, the Residential Tenancies Authority says the maximum bond for general tenancies is four weeks' rent.
| Weekly rent | 4 weeks' bond | 2 weeks in advance | Cash needed to start |
|---|---|---|---|
| $450 | $1,800 | $900 | $2,700 |
| $500 | $2,000 | $1,000 | $3,000 |
| $550 | $2,200 | $1,100 | $3,300 |
Illustrative only. Your lease and state rules decide the real amounts, and the bond is lodged with a government authority and refundable at the end of the tenancy if all is well.
Then add the costs people forget: removalists or a trailer, connection fees for electricity, gas and internet, overlap rent if you pay two places for a week or two, and basics for the new place. Write your own list before you apply. The moving out of home costs guide adds up a full upfront total you can compare with your own list.
Plan rent alongside everything else: Payday Buffer is an Excel workbook that starts from your pay, takes off the bills due before your next payday, essentials and upcoming costs, and gives you a Safe to Spend estimate. To compare your budget with what you actually spend in each category, Fortnightly Budget Plus has a budget vs actual tab and savings goals. Both are Excel workbooks and neither connects to your bank.
It is a useful check, not a rule that fits every household. Compare it with your take-home pay and your other bills.
The 30% benchmark uses gross income. For your own budget, check against take-home pay as well, because that is what you pay rent from.
At least the bond and rent in advance, plus moving costs and a small buffer.
