Average Mortgage Repayments in Australia

Average mortgage repayments in Australia’s latest published Census were a median $1,863 a month in 2021. That historical household figure isn’t a current 2026 mean repayment. For a present-day illustration, a hypothetical $500,000 loan at 6% over 30 years costs about $2,998 a month in principal and interest.

Current Average Mortgage Repayments

The Australian Bureau of Statistics (ABS) reports a national median mortgage repayment of $1,863 per month in its 2021 Australia QuickStats. The population is occupied private dwellings owned with a mortgage or purchased under shared equity, excluding visitor-only and other non-classifiable households. The unit is the household’s repayment for its occupied dwelling, not a payment per person or per loan.

The reference point is Census night, 10 August 2021. The 2021 housing release was published on 28 June 2022. A median is the middle reported value, whereas a mean adds the payments and divides by the number of observations.

These ABS releases don’t supply a current national mean dollar repayment. The 2026 Census product guide, released on 28 July 2026, schedules the first results for June 2027. The 2021 median remains a dated observed benchmark until newer results are available.

A newer survey answers a different question. Finder’s 2026 Home Loan Report, updated on 14 September 2026, reports a mean 38% of take-home pay spent on repayments. Its July 2026 survey has 286 mortgage holders supplying numeric responses for that measure.

That percentage doesn’t establish average dollars per month. Multiplying it by an unrelated average income would combine different populations and would not recover an observed repayment average.

Define the Dataset and Frequency

The Census statistic measures household-reported repayments for the home occupied on Census night. It doesn’t measure investors’ payments on all investment properties, every outstanding loan or only new borrowers.

The 2021 Census repayment definition accepts household responses, including a best estimate when the exact amount is unknown. Nil repayments are recorded as $0. Council rates, water rates, repairs, maintenance and body corporate fees are excluded.

The Census covers the population rather than drawing a small household sample. The repayment variable’s non-response rate was 6.0%. The ABS notes possible recognition errors in paper responses and accepts numeric responses as reported after data assurance checks.

Use the current QuickStats value when citing this benchmark. Its headline labels the result as monthly, and the repayment definition’s dollar category runs from $0 to $9,999. A new Census dictionary describes the next collection, but does not itself supply new observed repayment results.

Finder’s July 2026 survey collected 1,010 responses from Australians aged 16 and over, including 291 current mortgage holders. The report says its sample matches national age, gender and state distributions. Its published methodology doesn’t provide detailed weighting factors or a revisions series.

The 286 numeric responses are the denominator for the mean income share. Five mortgage holders don’t contribute to that calculation. Neither that sample nor its percentage can be treated as a Census household-dollar statistic.

Another common mismatch is housing costs. The ABS Housing Occupancy and Costs release, published on 25 May 2022, covers 2019-20. Its mean weekly housing costs include more than mortgage repayments, so they cannot be used as a newer weekly version of the Census median.

Weekly and Monthly Comparisons

The 2021 Census median converts to about $430 per week or $860 per fortnight under a 52-week budgeting convention. These are converted equivalents of the same monthly figure, not separately observed weekly or fortnightly averages.

Use 12 months, 52 weeks and 26 fortnights per year for this convention. Keep the population, period and repayment definition unchanged when converting.

Frequency	Calculation from the same 2021 median	Converted amount
Monthly	Published Census amount	$1,863
Fortnightly	$1,863 × 12 ÷ 26	$859.85
Weekly	$1,863 × 12 ÷ 52	$429.92

To convert a weekly amount back to monthly, multiply it by 52 and divide by 12. Dividing monthly repayments by four understates the annual cost because four weeks per month accounts for only 48 weeks.

A budgeting conversion also differs from a lender’s repayment schedule. Paying half a monthly amount every fortnight produces 26 half-payments, equivalent to 13 monthly payments a year. That is an extra month’s repayment compared with 12 monthly payments.

Observed Average Versus Modelled Repayment

An observed repayment comes from what households or lenders report paying. A model calculates a payment from an assumed balance and loan terms. Neither an average new-loan amount nor a property purchase price establishes the balance held by a typical existing mortgage holder.

The average mortgage guide explains those balance and borrower definitions. A $500,000 house also isn’t necessarily a $500,000 mortgage, because the deposit and financed costs change the amount borrowed.

Calculate a Repayment From Your Inputs

For a hypothetical principal-and-interest loan, use the following monthly formula. Principal is the amount owed, and interest is the charge for borrowing it.

M = P × r ÷ (1 − (1 + r)^(-n))

Here, M is the monthly payment and P is the loan balance. The monthly interest rate r is the annual rate divided by 12, expressed as a decimal. The number of payments n is the remaining years multiplied by 12.

For the illustrative $500,000 balance, assume a constant annual rate of 6%, a 30-year remaining term and monthly principal-and-interest repayments. Then r = 0.06 ÷ 12 = 0.005 and n = 360. The calculated payment is $2,997.75 per month before rounding.

This model assumes payments at each month’s end, zero fees, a zero offset balance and scheduled payments only. It uses monthly compounding and holds the rate constant throughout the term. It is a hypothetical calculation, not a surveyed average or a quoted lender rate.

Moneysmart’s mortgage calculator, updated on 2 October 2026, also distinguishes model estimates from predictions and loan eligibility. Actual lender calculations can differ because of daily interest, payment dates or fees.

Illustrative Repayments by Loan Balance

Every row below uses the same hypothetical 6% rate, 30-year remaining term and monthly principal-and-interest model. Only the balance changes. Fortnightly and weekly columns convert the unrounded monthly result using 12/26 and 12/52, then round to whole dollars.

Loan balance	Monthly model	Fortnightly equivalent	Weekly equivalent
$50,000	$300	$138	$69
$100,000	$600	$277	$138
$150,000	$899	$415	$208
$200,000	$1,199	$553	$277
$250,000	$1,499	$692	$346
$300,000	$1,799	$830	$415
$350,000	$2,098	$969	$484
$400,000	$2,398	$1,107	$553
$450,000	$2,698	$1,245	$623
$500,000	$2,998	$1,384	$692
$550,000	$3,298	$1,522	$761
$600,000	$3,597	$1,660	$830
$650,000	$3,897	$1,799	$899
$700,000	$4,197	$1,937	$969
$750,000	$4,497	$2,075	$1,038
$800,000	$4,796	$2,214	$1,107
$850,000	$5,096	$2,352	$1,176
$900,000	$5,396	$2,490	$1,245
$950,000	$5,696	$2,629	$1,314
$1,000,000	$5,996	$2,767	$1,384
$1,500,000	$8,993	$4,151	$2,075
$1,700,000	$10,192	$4,704	$2,352

Under those assumptions, a $700,000 mortgage costs about $4,197 per month and an $800,000 mortgage about $4,796. These amounts answer a repayment calculation, not an average-payment question. The weekly equivalents are cash-flow comparisons, not recalculated weekly loan schedules.

For interest-only calculations at the same hypothetical 6% rate, $700,000 × 0.06 ÷ 12 gives $3,500 monthly interest. A $600,000 balance gives $3,000. Neither payment reduces principal, and daily interest or changing balances alter the actual debit.

The smallest modelled payment isn’t automatically the best loan. A longer term lowers the scheduled payment but extends the time you pay interest. Compare the total cost alongside the repayment you can sustain.

Why the Average Does Not Set Affordability

A national mortgage repayment statistic cannot decide whether your client’s repayment is sustainable or whether a lender will approve their application. Two households making the same payment can have different income, dependants and other debts.

For an individual assessment, replace every benchmark input with verified client information.

• Obtain the current balance for each loan and the amount of any proposed borrowing.
• Record the actual product rate, remaining term and any fixed-rate expiry.
• Identify principal-and-interest or interest-only repayments, including when an interest-only period ends.
• Confirm repayment frequency, scheduled debits, fees and accessible offset or redraw funds.
• Verify income after tax, its stability and the lender’s treatment of each income source.
• Review living expenses, dependants, property costs and foreseeable changes.
• Record liabilities and commitments, including credit-card limits and other loan payments.

A salary percentage is only a starting comparison. Calculate mortgage payments divided by income on a matching frequency, then identify whether the income is gross or after tax. A 30% share of take-home pay is different from 30% of gross pay.

For a fictional household taking home $8,000 per month, the modelled $2,998 payment uses about 37.5% of that income. Whether it is sustainable depends on the money left for living costs, other debts and a buffer. The percentage alone supplies no approval result.

Loan serviceability is the lender’s assessment of whether the borrower can meet the debt repayments. It uses lender-specific income and expense treatment, so the advertised product payment and assessed repayment can differ.

A broker can use Bulma’s Scenario Planner to compare borrowing power and lender conditions for the client’s verified circumstances. Bulma’s Policy Advisor quotes the lender wording behind policy answers. Keep those conditions with the file and give the client a repayment calculation based on their actual loan terms.
