Interest-Only vs Principal & Interest Loans
Interest-only repayments lower your short-term cash outlay, while principal and interest loans reduce your overall debt and save on total interest over the life of the home loan.
Which repayment option suits me?
Choosing between interest-only (IO) and principal and interest (P&I) repayments depends on your broader financial strategy, current cash flow, and property goals. P&I repayments are the standard choice for most owner-occupiers because every payment actively reduces your underlying loan balance, building home equity faster and minimising the overall interest charged over the life of the loan.
Conversely, interest-only repayments lower your immediate ongoing commitments because you only pay the monthly interest accrued on the debt. This structure is commonly used by property investors wanting to maximise tax deductions, or home buyers navigating short-term cash constraints like parental leave or property renovations, though lenders generally charge higher interest rates for IO terms.
However, interest-only terms are temporary, typically lasting between one and five years. When the IO period expires, your repayments will automatically revert to P&I and increase significantly, as you must pay off the full principal balance over a shorter remaining loan term, directly affecting your serviceability.

Related questions
- Are interest-only loans more expensive in the long run?
- Yes, because you do not pay down the principal balance during the interest-only period, interest accrues on the full loan amount for longer, increasing total loan costs.
- Can owner-occupiers get an interest-only home loan?
- Yes, owner-occupiers can apply for interest-only terms, though lenders generally impose stricter serviceability criteria and require a clear justification.
- How does switching to principal and interest affect monthly repayments?
- Switching to P&I increases your monthly repayment amount because you begin paying down the loan balance alongside the interest.
- Does choosing an interest-only period affect my borrowing capacity?
- Yes, lenders assess your ability to repay the loan based on the shorter remaining P&I term, which often reduces your total borrowing capacity.
