Good Debt vs Bad Debt
In Australian lending, debt is not classified by intent or emotion.
It is classified by tax treatment, cash-flow impact, and risk exposure.
The terms “good debt” and “bad debt” are shorthand used to describe how debt behaves within the lending system.
What Is “Good Debt”?
“Good debt” generally refers to debt that:
- is income-producing
- may be tax-deductible
- is assessed with more flexibility by lenders
Common examples include:
- investment property loans
- business lending
- some commercial or income-backed facilities
This classification affects serviceability treatment, not approval certainty.
What Is “Bad Debt”?
“Bad debt” refers to debt that:
- does not produce income
- is not tax-deductible
- relies entirely on personal cash flow
Examples include:
- owner-occupied home loans
- personal loans
- consumer credit facilities
These debts are assessed conservatively because they offer no offsetting income.
Why Lenders Make This Distinction
From a lender’s perspective:
- income-producing assets can help service their own debt
- non-deductible debt relies solely on borrower income
- risk is higher when debt cannot self-support
This distinction affects:
- borrowing capacity
- acceptable loan structures
- long-term risk weighting
Interaction With Structuring
Debt classification influences:
- use of offset accounts
- interest-only vs principal & interest terms
- sequencing decisions across portfolios
These are structural outcomes, not strategies.
