Rent Review Calculator Perth
How much rent should you be charging for your Perth investment property? If you have not reviewed your rent in the past 12 months, you could be leaving thousands of dollars per year on the table. Perth's rental market has seen sustained growth, with REIWA reporting median weekly rents of $720 for houses and $690 for units in early 2026. Vacancy rates remain below 1% in many suburbs, properties are leasing in 7 to 11 days, and landlords have strong pricing power.
Use our free rent review calculator below to compare your current rent against your suburb's REIWA median, calculate what a CPI-based increase would look like, or benchmark your rent against comparable listings. The tool also checks whether you are legally eligible to increase rent under the Residential Tenancies Act 1987 (WA), which limits increases to once every 12 months with 60 days' written notice.
Whether you are self-managing or working with a property manager, understanding where your rent sits relative to the market is the first step to maximising your investment return.
How much can you increase rent in Perth?
There is no percentage cap on residential rent increases in Western Australia. Unlike some other Australian states, WA landlords can set rent at whatever the market will bear, provided the increase is not excessive or retaliatory. The Magistrates Court can determine whether an increase is reasonable if challenged by a tenant, considering comparable rents in the area, the condition of the property, and the circumstances of the increase.
In practice, most Perth landlords use one of three methods to calculate a rent increase: a CPI-based increase (currently 4.4% for Perth), a market-based review using REIWA suburb median data, or a comparable benchmarking approach using current rental listings. Our calculator below supports all three methods.
WA rent increase rules explained
Under the Residential Tenancies Act 1987 (WA), as amended in July 2024, rent can only be increased once every 12 months. The landlord or property manager must give the tenant at least 60 days' written notice on the prescribed Form 10 before the new rent takes effect. The notice must clearly state the new weekly rent amount and the date it will commence.
If a lease is renewed with the same tenant (or at least one existing co-tenant), it is treated as a continuous agreement. This means the 12-month clock runs from the date of the last increase, not from the start of the new lease. Two or more fixed-term agreements for the same people and the same property are also treated as one continuous agreement, so landlords cannot use short leases to get around the 12-month rule.
If rent has never been increased since the lease started and the tenancy has been running for more than 12 months, you are eligible to apply an increase now. Use our calculator to check your specific dates and generate your timeline.
