Common questions
Terms explained
- Emergency fund
An emergency fund is cash set aside for unexpected costs or lost income, often three to six months of essential spending.
- Sinking fund
A sinking fund is money you put aside regularly for a known future cost, such as insurance, rates or a holiday.
- Term deposit
A term deposit locks your money with a bank for a fixed time at a fixed interest rate.
- Offset mortgage
An offset mortgage links your savings and everyday accounts to your home loan, so you only pay interest on the loan balance minus those savings.
