Price to Rent Ratio: How to Calculate and Use It in Australia

Price to Rent Ratio: How to Calculate and Use It in Australia

The price to rent ratio is a property’s purchase price divided by its annual rent. A result of 20 means the property costs 20 years of rent to buy. The lower the number, the more rent you collect for each dollar of price. It is a fast first screen for comparing suburbs and for judging whether renting or buying looks cheaper, but it is never a verdict on its own. This guide shows the maths with Australian weekly rents, what the benchmarks mean, how the ratio relates to rental yield, and where it can steer you wrong.

What the price to rent ratio actually measures

The ratio answers a simple question: how many years of rent would it take to add up to the price of the property? Global Property Guide describes Australia’s ratio as the relationship between a dwelling’s price and its annual rent, and uses it to judge whether buying or renting is more cost-effective in a market.

It gets used in two different ways, and it helps to know which one you are doing.

  • Rent versus buy. If you live in the place, a high ratio says buying is expensive relative to renting the same kind of home. A low ratio says the opposite.
  • Investing. If you are buying to rent out, the ratio is a shorthand for income. A lower ratio means more gross rent relative to the price, which points to a stronger gross yield. A higher ratio means less rent relative to price, which can make positive cash flow harder to reach.

The same number reads differently depending on which question you are asking. A ratio of 28 in a blue-chip suburb might tell an owner-occupier that renting is cheaper month to month, while telling an investor that the income side is thin and the return depends heavily on growth.

How to calculate it, step by step

The formula is one line:

Price to rent ratio = purchase price ÷ annual rent

Australian listings quote rent per week, so the only trap is the conversion. Multiply weekly rent by 52 for the annual figure. If you only have monthly rent, multiply by 12.

  1. Find the realistic purchase price. Use recent comparable sales, not the agent’s asking price.
  2. Find the realistic rent. Use what similar properties have actually leased for recently, not what is currently advertised.
  3. Convert rent to a yearly figure (weekly × 52).
  4. Divide price by annual rent.

A worked example

Take a $900,000 property renting at $750 a week. Annual rent is $750 × 52 = $39,000. The ratio is $900,000 ÷ $39,000 = 23.1. That is the same example used in a Brisbane walk-through of the formula.

Here are a few more cases to show how much weekly rent moves the answer. These prices are illustrative, not market quotes.

Price Weekly rent Annual rent Ratio Gross yield
$600,000 $560 $29,120 20.6 4.85%
$750,000 $600 $31,200 24.0 4.16%
$900,000 $750 $39,000 23.1 4.33%
$1,200,000 $800 $41,600 28.8 3.47%

Notice that a $1.2 million home on a strong $800 weekly rent still produces a ratio near 29. Price, not rent, is doing most of the work at the top of the market.

What counts as a good ratio

The widely quoted benchmarks come from Global Property Guide: below 16 generally favours buying, 17 to 20 is broadly comparable, and above 21 generally favours renting. The same page lists Australia as a whole at a ratio of 23, which is a gross yield of 4.69%.

By that yardstick, the typical Australian home sits in “renting is cheaper” territory. That does not mean nobody should buy. It means the rent-versus-buy decision in Australia usually rests on growth, forced saving, tax treatment and how long you plan to hold, not on monthly running costs alone.

Treat the thresholds as a rough guide, because there is no universal good ratio for an Australian suburb. A low ratio can reflect something unattractive: maintenance problems, flood exposure, weak buyer demand or oversupply. A high ratio can reflect things buyers pay for: scarce land, school catchments, walkability and strong owner-occupier demand. A suburb at 32 may be a better long-term hold than one at 17, or it may not. The ratio cannot tell you.

Reading the number as an investor

A rough working guide, assuming you are screening for income:

  • Under about 20 (yield above 5%). Strong gross income. Check why. Is the price low because of a flood overlay, a single-employer town, or a pile of new apartment supply?
  • 20 to 25 (yield 4% to 5%). Typical for many Australian markets. Returns depend on growth and on keeping costs and vacancy low.
  • Above 25 (yield below 4%). Income is thin. The case rests on capital growth, and you will probably fund a holding cost from your own pocket.

These bands are our own working shorthand for screening, not an official standard. Your own borrowing costs decide where the line sits for you.

Price to rent ratio and rental yield are the same idea

Yield is the ratio flipped over: gross yield = annual rent ÷ price × 100. A ratio of 20 equals a 5% gross yield, and a ratio of 25 equals 4%. To convert, divide 100 by the ratio, or divide 100 by the yield.

If you already think in yields, you have lost nothing by learning the ratio. If you want a deeper walk-through of the yield side, our guide to gross rental yield for investors covers it, and why rental yield matters explains where it fits in a wider plan.

The important word is “gross”. Both measures are calculated before expenses. NAB separates gross rental yield before expenses from net rental yield after ongoing costs, such as council rates, insurance, repairs, maintenance, management fees, strata fees and vacancy.

What the net picture can look like

Return to the $900,000 property earning $39,000 a year. Suppose, purely as an illustration, that rates, insurance, strata, management, repairs and a few weeks of vacancy total $11,000. Net rent is $28,000, a net yield of about 3.1%, against the 4.33% gross figure. The headline ratio of 23.1 never showed that gap.

Then add the mortgage. Interest is not in either figure, and for a leveraged investor it is usually the largest cost. Moneysmart’s guidance on buying an investment property says to compare expected income with expenses and to consider whether you could cover a shortfall over the long term, including periods without tenants.

Comparing suburbs without fooling yourself

The most common use of the ratio is suburb screening: divide the median price by median annual rent and rank the results. That works only if the inputs match. A suburb ratio can be quietly wrong in four ways.

  1. Mixing dwelling types. A suburb’s house median and unit median can be very different. Compare houses with houses and units with units. Global Property Guide’s own Australian figure uses median prices and rents for one-, two- and three-bedroom dwellings, then averages the ratios, which shows how much the definition matters.
  2. Mixing time periods. A price median from the last 12 months set against a rent median from last quarter will skew the answer. Research using neighbourhood data, such as an ABS-hosted study of about 2,300 Australian neighbourhoods, pairs transaction-weighted annual medians for prices and rents, which is the discipline worth copying: same geography, same dwelling type, same measure, same date.
  3. Thin samples. In a suburb with few sales or leases, a median can jump on three transactions. Check how many sales sit behind the number.
  4. Medians versus the actual property. The median home is not your home. A renovated three-bedder near the station will not behave like the suburb median.

Rents differ widely between cities

Rents give the denominator its character. Domain’s March 2026 report put median weekly rents at Sydney $800, Perth $740, Darwin $720, Canberra $700, Brisbane $680, Adelaide $640, Hobart $620 and Melbourne $590. Over a year those are $41,600 in Sydney and $30,680 in Melbourne. A city with strong rents can still produce a high ratio if prices run ahead, so always pair the rent figure with a price from the same period.

Median weekly rents compared across Australian cities

The same report noted Perth’s vacancy rate at 0.3% and capital-city unit rents rising 3.8% over the quarter as renters shifted from houses towards apartments. Tight vacancy supports rent growth, which can pull a ratio down over time if prices do not keep pace. Our pieces on supply and demand in Australia’s property market and forecast rental growth go into what drives those moves.

There is also a demand-side effect worth knowing about. The ABS-hosted study found that a one-percentage-point rise in net overseas migration as a share of local population lifted house rents by 2.8% and unit rents by 4.3%, and unit prices by 3.2%. The effect on house prices was not statistically significant in the baseline results. Migration can therefore push rents up faster than prices in some places, which is one way a ratio shifts without any change in the buildings.

Check rent against an official range

If you are renting rather than investing, or want a sanity check on an advertised rent, NSW Fair Trading’s Rent Check shows the median rent range for homes in the current NSW rental market. Other states publish their own data through their tenancy or housing bodies.

Where the ratio misleads

The ratio is a screen, and a screen leaves things out. The main gaps:

  • Financing. It omits mortgage costs, interest rates and loan terms. Two buyers on the same property face very different holding costs.
  • Capital growth. A high-ratio suburb that grows quickly can beat a low-ratio one that stalls. Equally, a high ratio with no growth is an expensive way to hold.
  • Running costs. Strata levies in an older apartment block can swallow the rent advantage a low ratio promised. Insurance in flood or bushfire-exposed areas has moved sharply in some regions.
  • The median is not your property. Condition, aspect, land size and lease history all change the real rent and real price.
  • Vacancy. A listed rent is not collected rent. Weeks without a tenant cut your actual income.

A sound routine is to use the ratio as an initial screen, test the price against comparable sales and the rent against recently leased comparables, then account for vacancy, rates, insurance, body corporate levies, management, repairs and capital works. Also look at supply pipelines, planning overlays and how easily the property would resell.

The 2% rule and why it rarely fits Australia

The 2% rule says monthly rent should equal 2% of the purchase price. That is a ratio of about 4.2 years of rent per dollar of price, or an annual gross yield of 24%. One Australian lending FAQ says that this is rarely achievable in Australia. Against a national figure near 23 times rent, you can see why: a 2% rule property would need to cost around four years of rent.

The rule is an American rule of thumb that survives mostly as a conversation starter. Use the ratio and net yield with your own numbers instead.

Using the ratio in a rent-versus-buy decision

If you are a renter weighing up a first home, the ratio helps you frame the choice without settling it. A high ratio says the monthly cost of owning, once interest and upkeep are added, will probably exceed rent. That gap can be worth paying if you expect growth and plan to stay put, and not worth paying if you might move in a few years.

A third path is rentvesting: renting where you want to live and buying where the numbers work better, often in a cheaper market with a lower ratio. It brings its own trade-offs, including land tax, a landlord’s costs and no home-owner exemptions. Our guides on rentvesting risks and renting versus buying wealth outcomes lay out what to check.

Turn the ratio into a 15-year view

The ratio tells you what a property looks like today. What you really want to know is where your net worth lands in 15 years under each choice. That depends on rent increases, growth, interest rates, tax and your savings rate, none of which the ratio contains.

A practical checklist before you rely on a ratio

  1. Write down the geography, dwelling type, bedroom count and date for both price and rent.
  2. Use sold prices and leased rents, not asking figures.
  3. Convert weekly rent with × 52, and check the result against gross yield.
  4. Subtract realistic running costs to get a net yield.
  5. Add your own loan repayments to see the holding cost per week.
  6. Look at supply, vacancy and hazard risks such as flood overlays.
  7. Only then ask what growth you would need to make the purchase worthwhile.

If a suburb only works when you assume strong growth, you are speculating on growth, which is a legitimate choice but a different one from buying for income. For personal advice on a purchase, speak with a licensed financial adviser, a mortgage broker and your accountant about the tax effects.

FAQ

What is a good price to rent ratio in Australia?

On the widely used benchmark, below 16 favours buying, 17 to 20 is roughly even, and above 21 favours renting. Australia as a whole sits around 23, so a good number depends on your goal. Investors chasing income look for lower ratios, but should check why a suburb’s ratio is low before they buy.

How do I convert the price to rent ratio into rental yield?

Divide 100 by the ratio. A ratio of 20 gives a gross yield of 5%, and a ratio of 25 gives 4%. This is gross yield, before rates, insurance, management, repairs, strata fees and vacancy, so your net yield will be lower.

Can I use the ratio to compare suburbs?

Yes, as a first filter, if the inputs match. Use the same dwelling type, the same period and enough sales behind each median. Then check each shortlisted suburb’s vacancy, supply and hazard risks before drawing conclusions.

What is the 2% rule, and does it work in Australia?

The 2% rule says monthly rent should equal 2% of the purchase price. Australian lending commentary describes this as rarely achievable here. It is better to work from the ratio, net yield and your own cash flow.
