Offset and revolving credit are often discussed as if they are the same strategy. They can both reduce interest when cash is retained, but the way you see and use that cash is different.
How offset works
With an eligible offset structure, linked savings and transaction balances reduce the mortgage amount used for interest calculation. The savings remain visible in separate accounts.
This separation can suit people who want clear emergency, bills and savings accounts while still obtaining an interest benefit.
How revolving credit works
A revolving-credit facility operates more like a large transactional credit account. Income can reduce the balance, while spending and withdrawals increase it again.
It can be flexible, but it also makes available credit easy to reuse. Strong account rules and a suitable limit matter.
The practical suitability test
- Do your savings remain stable or are they regularly spent?
- Do you carry a credit-card balance?
- Do you prefer separate accounts or one flexible facility?
- How much cash is likely to remain available over time?
- Are the product rate and fees reasonable for the expected benefit?
The best structure is not determined by the product name. It depends on your cash position, behaviour, bank options and wider mortgage plan.
