Renting Scenario

$/wk
% p.a.

If you rent instead of buying, your deposit stays invested. This is the assumed annual return on that money.

% p.a.

Renter invested amount

Deposit + stamp duty + upfront costs = $179,250

The renter keeps all money the buyer spends upfront and invests it at the assumed return rate. This is the opportunity cost of buying.

Portfolio value at year 10: $352,612

Break-even at year 7

With the assumptions you entered, the buying scenario overtakes the renting scenario at year 7. Net wealth difference at year 10: $81,097.

Renting versus buying a home in Australia

The choice between renting and buying is partly financial and partly personal. On the financial side, buying builds equity over time but comes with large upfront and ongoing costs, while renting keeps your money free to invest elsewhere. This calculator compares the two by projecting your wealth under each path over a time horizon you choose.

The buying path builds equity as you pay down the loan and as the property changes in value. The renting path assumes you invest the money you would have spent on a deposit and buying costs, plus any yearly difference in cost, so the two can be compared on the same footing. It is a model and general information, not financial advice, and the result depends heavily on the assumptions you enter.

How to use this calculator

1

Enter the property and rent details

Add the purchase price, your deposit, the loan rate and term, and the rent for a similar home.

2

Set the growth and return assumptions

Enter expected property growth, rent increases, and the return on money invested while renting.

3

Add the costs

Include upfront buying costs such as stamp duty, and ongoing costs such as rates, insurance and maintenance.

4

Choose the time horizon

Set how many years to compare. The calculator shows the wealth under each path and where they cross over.

How this calculator works

The calculator projects two paths year by year. On the buying path, it tracks your loan balance as you make repayments, applies your property growth assumption to the value, and subtracts ownership costs, to estimate your equity over time. On the renting path, it invests your deposit and buying costs at the return you set, adds any yearly saving from renting rather than owning, and grows that balance, to estimate your investment wealth over time. It then compares the two and marks the year they cross over.

Assumptions used

Assumptions used: the comparison invests the money not spent on buying, so it measures wealth, not just cost. Buying costs include the deposit and upfront costs such as stamp duty, and if the deposit is under 20% of the value, lenders mortgage insurance may apply. Ongoing ownership costs such as council rates, insurance and maintenance are estimated from your inputs. A main residence is generally exempt from capital gains tax, while returns on money invested while renting are usually taxable. Growth rates, rents and returns are your assumptions and are not guaranteed. The estimate is general information, not financial advice.

Worked example

Example only

A buyer purchases a $700,000 home with a $140,000 deposit and borrows the rest, while a renter pays rent on a similar home and invests the $140,000 deposit plus buying costs. Both paths are projected over 10 years.

Whether buying or renting comes out ahead depends on the assumptions. Higher property growth favours buying, while a higher investment return and lower property growth favour renting. The calculator shows the crossover year for the figures you enter, rather than a single answer.

Small changes in growth and return assumptions can flip the result over a long horizon, so it is worth testing a range.

What tips the rent versus buy result

Several assumptions shift the balance between the renting and buying paths. The main ones are:

Property growth

The rate the home is assumed to grow in value has a large effect on the buying path over a long horizon.

Investment return

The return on money invested while renting drives the renting path. A higher return favours renting.

Time horizon

Buying tends to look stronger the longer you hold, because upfront costs are spread over more years.

Upfront buying costs

Stamp duty, legal fees and, for deposits under 20%, lenders mortgage insurance add to the cost of buying.

Ongoing ownership costs

Council rates, insurance, maintenance and any strata fees reduce the return from owning.

Tax treatment

A main residence is generally exempt from capital gains tax, while returns on investments are usually taxable.

Frequently asked questions

There is no single answer. The outcome depends on property growth, the return you could earn by investing, the time horizon, and the costs of buying and owning. This calculator projects both paths from your assumptions and shows where they cross over.
