How Much Cash Should You Actually Hold? (The Offset Changes Everything)

Most money advice tells Australians to keep 3-6 months of expenses in cash "for emergencies" - and then park it in a savings account earning almost nothing after tax. But if you have a mortgage with an offset, your emergency fund can earn your loan rate - around 6%, completely tax-free - AND still be in your hands by Tuesday if life happens. Same safety, more than double the after-tax return, and it's the government's own MoneySmart site that says to do it. So the real question was never "how much cash" - it's WHERE it should live, and HOW MUCH is actually enough. We run the honest maths on a persona (Sarah, $150k, Sydney apartment) and turn the dial for every situation - single, couple, kids, unstable income - plus the one mistake careful people make: holding too much. ⏱ CHAPTERS 0:00 The offset changes everything (the one-year race) 1:22 Sarah & the number that actually matters 2:20 Where it lives: the offset IS your emergency fund 3:49 How much?
