Mortgage Interest Charges Rose 8.2% in the June Quarter, ABS Says

Short summary

Mortgage interest charges in the employee household Living Cost Index rose 8.2% in the June quarter 2026, according to the Australian Bureau of Statistics release published on 5 August.

Employee-household living costs rose 1.5% over the quarter, the largest increase among the five household types measured. They were 3.7% higher over the year.

The 8.2% figure is an aggregate index movement, not a claim that every mortgage holder's repayment rose 8.2%. Loan balances, rates, repayment types, lender timing and fixed-rate periods vary. Use the Mortgage Repayment Calculator with the balance, rate and remaining term for a personal scenario.

What changed in the June quarter

The ABS said insurance and financial services, food and non-alcoholic beverages, and housing were the main positive contributors across the Living Cost Indexes.

Employee households recorded the largest quarterly increase because mortgage interest charges carry a higher expenditure weight for this household type. The index also captures other living costs, so its 1.5% movement should not be read as a mortgage-only result.

Why mortgage interest rose in the index

The ABS attributed the quarterly rise in mortgage interest charges to banks passing through the RBA cash-rate increases in February, March and May 2026 to variable-rate and new fixed-rate home loans.

Only part of the May increase was captured in the June-quarter index because of the timing of lender changes. The ABS says the remaining effect will appear in the September 2026 quarter.

That is a measurement-timing statement. It is not a prediction about the RBA's next decision or a forecast of an individual loan repayment.

The cash-rate target was 4.35% when this article was updated. The next scheduled RBA decision is 11 August 2026. Read the August RBA meeting preview for the timetable and verified inflation context.

Why 8.2% is not your repayment increase

The Living Cost Index tracks price change for a fixed basket associated with a household type. Mortgage interest charges are affected by both interest rates and the debt balances represented in the index.

A household repayment can move differently because:

• the loan balance may have fallen through principal repayments;
• a fixed-rate period may delay a rate change;
• a lender may change its rate on a different date;
• principal-and-interest and interest-only loans respond differently;
• an offset balance can reduce interest charged; and
• a borrower may refinance, redraw or make extra repayments.

Do not multiply a current repayment by 1.082 and treat the answer as a lender notice. Check the actual rate and effective date, then run the loan details through the calculator.

Worked repayment scenario

Consider a $600,000 principal-and-interest loan with 30 years remaining.

The example uses the standard amortising-loan formula and assumes the rate changes immediately while the balance and remaining term stay fixed. It excludes fees, offsets, redraw and lender-specific rounding.

The percentage change in this example happens to be close to 8%, but it was not calculated from the ABS index. A different balance, term or rate change produces a different result.

Use the Rate Change Impact Tool to compare a rate movement, or the Mortgage Stress Test for a wider household-budget scenario. Neither tool is a lender assessment or hardship determination.

Living Cost Indexes and CPI answer different questions

Australia's Consumer Price Index excludes mortgage interest charges. The Selected Living Cost Indexes include them because the LCIs are designed to measure the effect of price changes on the out-of-pocket living costs of different household types.

This is why employee-household living costs can move differently from CPI when mortgage rates change. The two measures use different purposes, populations and expenditure treatments.

Who may be affected

The release is most directly relevant to people trying to understand economy-wide mortgage-cost pressure and the difference between CPI and household living-cost measures.

It does not establish:

• how much a particular lender changed a rate;
• whether a household can afford a mortgage;
• whether a borrower will qualify for refinancing or hardship support;
• what the RBA will decide next; or
• whether property prices will rise or fall.

Borrowers concerned about meeting repayments should contact their lender promptly. ASIC Moneysmart's mortgage hardship guidance explains the general support process. A national index is not a substitute for that conversation.

Calculator and site impact

No calculator formula changed because of this ABS release. The 8.2% index movement is not an input to the mortgage repayment or borrowing-power calculators.

The site's current cash-rate context remains separate from retail mortgage rates. Users should enter the rate shown on their own loan documentation or a clearly identified scenario rate.
