Offset accounts work as a transaction account linked to your home loan. The money in that account 'offsets' daily against the balance of your loan. So, it reduces the interest you need to pay because interest is only charged on your net balance (i.e. your overall loan balance minus your offset account balance). In other words, the loan 'thinks' you've paid that money off your loan already, reducing the interest charged accordingly. Qudos Bank offers multiple offset accounts on most home loans, check with your lending specialist.
