Why 3 years is the most debated horizon

Three years sits in an awkward middle ground — long enough that ETFs could outperform savings significantly, but short enough that a market downturn could leave you worse off at exactly the wrong moment. The right answer depends almost entirely on one question: is your goal date fixed or flexible?

Fixed goal date vs flexible goal date

If you need the money on a specific date — say, a house deposit settlement or school fees — a 30% market drop in month 30 is a real problem. You'd be forced to sell at a loss with no ability to wait for recovery. In this case, a high-interest savings account or term deposit is the safer choice.

If your goal is flexible — say, you'd like to buy a car "around" 3 years from now but could wait another year or two — then ETFs become a more reasonable option. The flexibility to hold through a downturn changes the risk profile significantly.

What the numbers look like over 3 years

Scenario $10,000 invested Result after 3 years
Savings at 5% pa $10,000 ~$11,576
ETF at 7% pa (good run) $10,000 ~$12,250
ETF after 20% market drop (bad timing) $10,000 ~$8,000

The upside over savings is modest (~$674 in this example). The downside in a bad year is severe. That asymmetry is why many financial advisers recommend savings for fixed 3-year goals.

The Australian context

For Australians saving for a house deposit — one of the most common 3-year goals — the government's First Home Super Saver Scheme (FHSSS) offers a tax-advantaged alternative worth considering before choosing between ETFs and savings. For general 3-year goals, high-interest savings accounts currently paying 4-5% pa are a strong option while rates remain elevated.
