88. Savings vs offset vs investing: How each stacks up at 6% interest rates

Aussie FIRE | Financial Independence Retire Early

Show Notes

A few years ago mortgages were under 2% and cash earned you nothing. Now rates sit around 6% and every option looks different: savings accounts are suddenly respectable, offsets feel like a guaranteed win, and borrowing to invest looks scarier than it maybe is.

Dave and Hayden work through how a high-rate environment reshuffles the deck, and the mental shortcuts that lead people astray in both directions.

In this episode we'll discuss: 💸 Savings accounts are back, but interest is taxed at your marginal rate, and plenty of high earners forget that 5% is really more like 3%

💸 A quick test for whether you're carrying too much debt: how nervous do you get before RBA meetings?

💸 Dave's peak-debt confession: millions owed in his twenties, and why a 2% rate rise would have broken the strategy

💸 The offset trap: why "a guaranteed 6% return" isn't permanent (it moves with rates), and why "6% tax-free equals 10% invested" is the wrong comparison. Compare after-tax returns to after-tax returns

💸 Waiting for rate cuts before investing: why asset prices reprice on the way down, and if everyone has the same plan, you need to be early for it to work

💸 Dave's counterintuitive maths on borrowing to invest: how borrowing at 8% into a low-yield growth ETF can still come out ahead after the tax deduction

💸 Why people happily suspend the maths for property ($923 a week in interest on an $800k Sydney apartment) but won't extend the same long-term logic to shares

💸 Hayden's crusade: housing's advantages are mostly structural (CGT exemptions, pension treatment, cheap secured lending), and why he wants mortgage-rate loans against boring index ETFs to exist

💸 A cracking listener tip from Jared: pay a lump sum into the loan and ask the bank to recalculate your repayments. Unlike an offset, it actually improves your monthly cash flow

💸 The cherry-picked chart problem: the friend who "proved" property beats shares using 1998 to 2018, and why you should go find the raw data

The thread through all of it: know what a decision actually costs you over the long term before you anchor to big theoretical numbers.

Your FIRE plan might look perfectly reasonable on paper. But what happens when the share market drops, an investment property needs a $20,000 repair, interest rates rise or the government starts changing tax rules? And if financial decisions are keeping you awake at night, is the answer to change your investments, change your thinking or simply accept that some things are outside your control?

Where should a retirement cash buffer live when most of your wealth is already in super? If you're aiming to retire in ten years, is it better to build your outside portfolio first or split your investing between ETFs and super now? And once you're already retired, does it make sense to sell a large share portfolio just to get more money into super before pension phase?

Travel is supposed to be one of the things money gives you more freedom to enjoy. But when a holiday can cost $15,000 instead of $5,000, how do you keep seeing the world without feeling like every trip is sending your finances backwards?

If the goal is to live off your portfolio one day, why bother selling investments at all? Could you simply build a portfolio that throws off enough income to cover your spending, ignore the 4% rule and leave the assets themselves alone? It sounds neat. But once you look past the appeal of regular cash flow, the trade-offs get more interesting.

Retiring overseas might sound like a straightforward FIRE move. But what happens when your portfolio was built around Australia, changing tax residency could create a tax event, your partner has a completely different appetite for risk, or you finally start selling ETFs you have been buying for years?
