Hi all, this is probably a very silly question but I'm not great with getting my head around this and perhaps I'm overthinking it. Example: I have a home loan of $100,000 (for simplicity's sake) and it is linked to an offset account of which I have $80,000. At 4.04%, my monthly repayment of P+I is approximate $480 Should my loan interest for the month be calculated on the $20,000 ? which means a whopping $68? Or is this too simplistic a way of how offset accounts work? Looking at my end of month statement and I'm puzzled..
