So so so many people do this, so you are not alone. Money sitting in an old transaction or savings account instead of working hard in your offset. I get it, at first it feels weird letting go, of an almost emotional connection to your savings account that helped you get where you are today! This is one of those things that makes complete sense once you run the numbers but is genuinely counterintuitive before you do. A savings account earning 4-5% maybe even 5.5% for a good one, while a home loan is charging 6%+ is a net negative position. Quick example to check your own position: Let's use these easy numbers, you use your own. $500,000 loan amount 6% p.a. $20,000 sitting in a savings Scenario 1 — No offset Interest on the full $500,000 at 6% p.a. = $30,000/year (500,000 x 1.06) The $20K in a separate savings account earns 5.5% interest which is $1,100/year interest (taxable), but does nothing to reduce the mortgage interest. Scenario 2 — Offset account Instead put the $20K into an offset so lower the overall mortgage balance, so interest is calculated on $480,000. $480,000 × 6% = $28,800/year (480,000 x1.06) The offset is almost always the better home for that money because banks never offer higher rates on savings accounts then they charge on home loans. Plus factor in the tax man. The offset saves you $1,200/year in mortgage interest — but crucially, the offset saving is tax-free, whereas the savings account interest is taxable income. For someone on a 37% marginal tax rate, the $1,100 from the savings account becomes roughly $693 after tax. The offset gives you the full $1,200. That's the real kicker for clients — same money, better outcome, no tax drag. So almost $2K better off simply by using smarter cash flow. I'm not suggesting anyone move their savings into an offset, that choice is entirely yours. This is all just me teaching you the principles. Just that it's worth thinking about whether there's money sitting somewhere that would be working harder in an offset.
