How the affordability calculation works

Income is converted to a weekly take-home amount. The calculator subtracts proposed rent, essential weekly costs and utilities to show the amount left. It separately calculates the upfront cash requirement from the entered bond weeks, rent in advance, moving or connection costs and emergency buffer.

The result also shows rent as a percentage of take-home income and a 30% benchmark. That benchmark is included for context, not as a guarantee that the property is affordable.

How to test a rental scenario

Use take-home income, not gross salary. Include groceries, transport, debt payments, insurance, medical expenses, phone, internet, childcare and other unavoidable costs in the essential-cost figure. Add a realistic utility amount even when the next bill is not due immediately.

Run a stress scenario with higher utilities, an unexpected transport cost and at least one week of income disruption. A rental that only works when every estimate is optimistic is risky.

Tenancy and budgeting limitations

Bond and rent-in-advance laws differ by state and territory and may depend on the rent level or tenancy type. The calculator does not enforce a legal maximum. Confirm the correct limits and permitted charges with the relevant tenancy authority.

The tool does not include every irregular annual expense and does not assess a rental application. Agents and landlords may use their own affordability checks and evidence requirements.

Frequently asked questions

Is the 30% benchmark a rule?

No. It is a broad indicator only. A household can be under 30% and still have unaffordable cash flow, or choose to spend more when other costs are low.

Why use take-home income?

Rent and household bills are paid from income received after tax and deductions.

Does the calculator apply my state bond limit?

No. Enter the applicable number of weeks and confirm the rule with your state or territory authority.

Should the emergency buffer be included in moving costs?

Yes. Keeping cash available after paying the bond and moving expenses reduces the risk that the move leaves the household with no margin for an unexpected bill.
