Question 1

How is the counter-offer calculated?

Accepted Answer

The calculator finds the break-even rent, which is the weekly amount at which your landlord nets the same income over 52 weeks whether they replace you or keep you at the lower rate. It factors in vacancy loss, reletting fees, advertising costs, and repairs. Three tiers (Conservative, Balanced, Assertive) are then calculated around that break-even point.

Question 2

Can I negotiate a rent increase in Australia?

Accepted Answer

Yes. Landlords are not obligated to accept any counter-offer, but negotiation is common and landlords often prefer keeping a reliable tenant over the cost and hassle of finding a new one. The best approach is to frame your counter-offer around the landlord's financial interests, not just your own.

Question 3

What does it cost a landlord to replace a tenant in Australia?

Accepted Answer

Typically $2,000–$5,000 or more, depending on location and property type. This includes vacancy loss (usually 2–3 weeks rent), a reletting fee (1–2 weeks rent charged by the agent), advertising on Domain and REA ($200–$400), and repairs or cleaning between tenancies ($300–$800+).

Question 4

What is a reasonable rent increase in Australia?

Accepted Answer

As a rough benchmark, increases in line with CPI (typically 3–5% per year in recent years) are generally considered reasonable. In 2024–25, CPI ran at around 3–4%. Anything significantly above that warrants scrutiny. The 'Balanced' counter-offer from this calculator gives you a specific number that still makes financial sense for the landlord — which is a stronger negotiating position than citing CPI alone.

Question 5

How much notice does a landlord have to give for a rent increase in Australia?

Accepted Answer

Notice periods vary by state and territory. In most states it is 60 days' written notice; in some it is 30 days. This calculator focuses on the negotiation side. For specific legal requirements in your state, check your state's tenancy authority website.

Question 6

How often can a landlord increase rent in Australia?

Accepted Answer

In most Australian states, a landlord can only increase rent once every 12 months. Queensland extended this to once every 12 months per property (not per tenancy) from June 2024. The exact rules depend on your state and whether you are on a fixed-term or periodic lease. If your landlord is attempting to increase rent more frequently than allowed, you can dispute it through your state's tenancy authority.

Question 7

Is this tool specific to any Australian state?

Accepted Answer

The calculator uses standard market cost assumptions that apply broadly across Australia. It does not account for state-specific tenancy law or rent increase caps, which vary by state. It is a negotiation support tool, not legal advice.
