Core Assessment Analysis

The Household Expenditure Method (HEM) is the baseline living cost used by 95% of Australian lenders. HEM is updated quarterly based on ABS data and is scaled according to your household size and gross income band. If your declared expenses are lower than the HEM floor, the bank's system automatically overwrites them with the higher HEM floor anyway.

Why Underwriters Focus Here

HEM acts as a regulator-approved risk floor to prevent banks from approving loans based on unrealistic living budgets.
