Australian households spent 7 per cent more in July 2026 than a year earlier, on ABS monthly indicator data, and every dollar of it is relevant to the least discussed part of any loan application: the living expense assessment. Income gets the attention; expenses quietly decide just as many outcomes.
What actually happens to your declared expenses
When you state your monthly living costs on an application, the figure is not simply accepted. Lenders compare it against a benchmark, most commonly the Household Expenditure Measure, a survey-based estimate of what households like yours, by income, region and family size, typically spend.
The mechanics matter: if your declared figure comes in below the benchmark, most lenders assess you at the benchmark anyway. Understating expenses does not improve your borrowing power; it just flags the application for a closer look. Overstating them costs you capacity you genuinely have. Accuracy is not a virtue here so much as the only strategy that works.
The statements tell the real story
Alongside the benchmark, lenders read bank statements, commonly covering the last 90 days, and modern assessment categorises transactions automatically. The things that draw attention are patterns, not one-offs: recurring subscriptions, gambling transactions, buy now pay later instalments, overdrawn accounts and dishonours.
Buy now pay later deserves its own sentence: those instalments are commitments, increasingly visible in credit reporting and always visible in statements, and a stack of concurrent plans reads as exactly what it is, spending pulled forward against future income. If an application matters, the 90 days before it is when the statements should look the way you want them read.
The expense categories that count, and the ones that do not
Lenders distinguish between committed expenses and discretionary spending, and the distinction works in your favour. Rent or mortgage payments, insurance, childcare, utilities and existing loan repayments are committed: counted in full, every time. Discretionary spending, dining, streaming, travel, is assessed more as a pattern, on the reasonable logic that a borrower can trim it if repayments require.
What trips applicants is spending that looks committed: the gym contract, the subscriptions that renew annually, the regular transfers that resemble obligations. A quick audit of what leaves your accounts on autopilot, cancelling what you would not miss, genuinely changes how the statements read, and usually improves your actual finances in the process.
Cost-of-living pressure meets the assessment
The 2026 squeeze is real: spending up 7 per cent year on year while wages grew 3.7 per cent, mortgage rates repricing after three cash rate increases. Benchmarks adjust to survey reality over time, and your own statements reflect today's grocery prices immediately.
The practical response is sequencing. The best time to trim expenses is at least three months before an application, so the statements show the leaner pattern as established rather than as a last-minute performance. Lenders have seen the month-old austerity program before; ninety days of genuine pattern is what reads as real. Pair that with knowing your actual surplus, income minus true expenses minus commitments, and you walk in knowing roughly what our calculators or any lender will conclude, before they conclude it.
Expenses are half the equation
Serviceability is a subtraction: income minus expenses minus commitments, against the proposed repayment. Our guides cover the other inputs, how income is assessed, what strengthens an application, and how your credit history prices your loan, but none of them outweigh the simple, boring power of statements that show a household living within its means.
Lenders are not looking for monks. They are looking for room: evidence that after life is paid for, the repayment fits. With spending rising faster than wages, demonstrating that room takes more deliberateness than it used to, which is exactly why the applicants who prepare for the expense assessment stand out in 2026.
