Your Cash Flow Is Set Up to Benefit the Bank — Here's How to Fix It

The Typical Aussie Cash Flow (And Why Banks Love It)

Banks have been training us since primary school. Separate accounts, separate spending, money scattered across multiple products. It makes tracking difficult, fee income high, and — most importantly — it ensures your money sits in accounts that work for them, not you.

Here's what the typical setup looks like: separate transaction accounts for each partner, a joint "high-interest" savings account, credit cards for each person, and cash withdrawals each week. Income goes into 0% accounts, stays there until spent, while the home loan sits at maximum balance collecting maximum daily interest.

What the Bank Sees

Separate accounts mean less accountability between partners — people spend more when their partner can't see the transactions. The "high-interest" account pays about half the home loan rate, and after tax, it's even less. Credit cards mean double the annual fees and hopefully some late payment fees too. Cash in your pocket earns no interest and saves no interest.

The Fix: Centralise Around Your Offset

Consolidate your cash flow around an offset account. Both incomes go in. All bills come out. Everything in between reduces your home loan interest.

For your investment expenses, set up a second offset account. Rental income goes in, investment costs come out, and the combined balance of both offsets reduces your home loan interest. Clean bookkeeping for tax time, maximum interest savings every day.

Draw Your Money Map

Take ten minutes and map out where every dollar flows. Green for income, blue for savings accounts, red for debts, orange for expenses. Connect them with arrows. If it looks like a dog's breakfast, you've probably got room to simplify — and save.
