Is your property cash flow positive?
Put in your actual numbers and see where the property really sits. Making money each month, breaking even, or topping up out of your own pocket.
What is it earning?
What the tenant pays now, or what you expect to achieve. Not sure? A free rental appraisal will tell you.
Enter the weekly rent to continue.
Roughly what it would sell for today. For scale, the Perth median house sale price was $938,000 at the end of June 2026 and the median unit $675,000 (REIWA). Your own suburb will differ, sometimes a lot.
Enter an estimated value. It is used for the yield and the maintenance budget.
How much empty time to build in each year. Two weeks is a sensible default. Choose more if the property turns over often or is hard to let.
What does it cost to hold?
Your regular holding costs. Leave anything that does not apply blank.
The fixed service and sewerage component, which is always the owner's in WA. Tenants can only be charged for the usage component.
Landlord and building cover.
From your assessment. Thresholds and rates change, so use the current notice rather than last year's.
Other annual costs specific to this property. Pool servicing, gardening, security monitoring, septic pump out.
What should you set aside for upkeep?
A percentage of the property's value. One per cent a year is the usual rule of thumb, though a newer or well kept property often runs below it.
Enter a property value above to see the budget.
What does management cost you?
The ongoing percentage plus the one off charges when a tenant changes. Those get spread across a typical tenancy so the annual figure is honest.
The ongoing rate on rent collected, including GST. Perth generally runs 8 to 11 per cent plus GST. Leave blank if you self manage. What the fees actually cover.
Letting fee, advertising, photography, condition report, changeover cleaning. Add it up and put the total here.

Important information
This is an indicative calculator, not financial advice. It gives a rough picture of a property's cash position from the figures you enter, plus some simplifying assumptions: the vacancy allowance you select, and an eighteen month average tenancy used to spread one off changeover costs. Actual cash flow depends on interest rate movements, real vacancy, maintenance you cannot predict and a good deal else this tool does not model.
Nothing you enter is saved, sent anywhere or recorded. The calculation happens in your browser and disappears when you close the page.
The terms positively geared and negatively geared are used here in their general sense, based on cash flow only. Tax outcomes, including how negative gearing rules apply to you, depreciation and capital gains, are not modelled and can change the after tax position materially. Note that the May 2026 Federal Budget changed the treatment of net rental losses on established homes purchased after 1 July 2027, with existing investors grandfathered. Whether and how that affects you is a question for a registered tax agent.
Market figures shown are from REIWA for the Perth metropolitan area, current at the June 2026 quarter. Median rent $750 a week for houses and $700 for units. Median sale price $938,000 for houses and $675,000 for units. These change quarterly.
