Why Your Mortgage Payments Are Missing from Australia's Inflation Figures (2026)

A Hidden Cost: The Impact of Home Loan Repayments on Inflation

The Real Cost of Homeownership

For countless Australians, the journey towards homeownership is a significant financial commitment. With interest rates on the rise, as seen this week, the burden of mortgage repayments becomes even more pronounced.

The Missing Piece in Inflation Figures

Here's where it gets intriguing: the increase in mortgage repayments isn't reflected in Australia's official inflation measurements. Why? It all stems from a request made by the Reserve Bank of Australia (RBA) to the Australian Bureau of Statistics (ABS) back in 1997.

A Decade-Long Inclusion, Then Exclusion

For about a decade, home loan payments were a part of the Consumer Price Index (CPI), one of the ABS's most critical economic indicators. However, at the RBA's request, the ABS shifted from an "outlays" model to an "acquisitions" model, excluding mortgage payments from the CPI.

The RBA's Perspective

The RBA's submission to the ABS reveals their concern. They believed that including mortgage payments in wage negotiations could fuel inflation, their key enemy. In their words, "interest rate increases are used to combat inflationary pressures." By excluding mortgage costs, they aimed to prevent a short-term spike in inflation.

The Impact on Macroeconomic Stability

The RBA argued that distorted signals from including mortgage payments could affect wage and price setting, ultimately harming macroeconomic stability. They insisted this exclusion wouldn't distort long-term outcomes, only the short-term CPI.

The Human Cost

While the RBA's concerns are valid, the financial pain experienced by mortgage holders is very real. When rates rise, borrowers must cut back on spending, feeling the pinch of higher living costs. This leads to slower demand for goods and services, which the RBA hopes will curb price increases.

A Global Practice?

The RBA claims that excluding mortgage costs is a common practice worldwide, with most countries instead including the cost of building a new home. However, for many Australians, mortgage repayments are a substantial and very real expense, with the average new home loan consuming 45% of median income.

The Cost-of-Living Index

In 1997, the ABS introduced a cost-of-living index that includes mortgage interest. For employees, this accounts for almost 15% of the index, similar to the food and non-alcoholic beverage category. This index provides a more accurate reflection of the financial stress experienced by Australians.

The Human Story

Financial Counsellors Australia reports a 10% increase in calls to the National Debt Helpline, with housing stress a leading reason. "People who are working full-time can't keep up with mortgage repayments and rising essential costs," says Domenique Meyrick. For these individuals, the RBA's inflation calculations are a distant concern compared to their immediate financial struggles.

And This Is Where It Gets Controversial...

So, is the RBA's approach to inflation calculation justified, or does it overlook the very real financial struggles of everyday Australians? What do you think? Share your thoughts in the comments!
