One of the most common financial questions Australians face: should I keep money in a savings account, or invest it in shares and ETFs? The answer depends on your time horizon, goals, risk tolerance, and what the money is for. This guide compares both approaches with worked Australian examples.
The Core Difference
| Feature | High-interest savings account | Share/ETF portfolio |
|---|---|---|
| Return | Fixed/variable — ~4.5–5.5% (2026) | Variable — historically 7–10% p.a. |
| Risk | Very low — government-backed to $250K | Moderate to high — can fall 30–50% |
| Liquidity | Instant access | Sell within 2 business days (T+2) |
| Guarantee | Yes (FCS up to $250K) | No |
| Best for | Short-term goals (<3–5 years) | Long-term goals (5+ years) |
| Tax | Interest is ordinary income | Dividends + CGT (50% discount after 12 months) |
Savings Account Returns — Current Australian Rates
High-interest savings accounts (HISA) in Australia as at 2026:
| Bank | Approx. rate | Conditions |
|---|---|---|
| ING Savings Maximiser | ~5.50% p.a. | Bonus rate conditions apply (monthly deposits, card use) |
| Macquarie Savings Account | ~5.35% p.a. | Bonus rate for first 4 months for new customers |
| Ubank | ~5.10% p.a. | Conditions apply |
| AMP Saver | ~5.00% p.a. | Conditions apply |
Rates vary and are not guaranteed. Check current rates at each institution and via comparison sites.
Term deposits (locked-in) currently offer 4.5–5.5% for 1–2 year terms at major banks (May 2026).
Comparison: $50,000 over 10 Years
Assumptions:
- HISA: 5% p.a. (variable — may change over time)
- Share portfolio (VAS/VGS): 8% p.a. (historical average — not guaranteed)
- Both: No additional contributions
| Year | $50K HISA (5%) | $50K Shares (8%) |
|---|---|---|
| 1 | $52,500 | $54,000 |
| 3 | $57,881 | $62,986 |
| 5 | $63,814 | $73,466 |
| 10 | $81,445 | $107,946 |
Difference after 10 years: ~$26,500 in favour of shares (before tax).
After Tax Comparison
HISA interest: Taxed as ordinary income each year at your marginal rate. For a 37% taxpayer (income $135K–$190K in 2025–26), 5% becomes ~3.15% after tax.
Share portfolio: CGT event only on disposal — 50% CGT discount if held 12+ months. Dividends taxed in year received (but franking credits often offset or reduce this). Effective tax rate on total return can be lower than HISA for most investors.
After-tax comparison ($50,000, 37% marginal rate):
| Year | HISA after-tax (~3.15%) | Shares after-tax (~6%+) |
|---|---|---|
| 5 | $58,374 | $66,911 |
| 10 | $67,973 | $89,542 |
| 20 | $92,197 | $160,357 |
Shares outperform significantly over long time horizons — even accounting for tax — but with meaningful year-to-year volatility.
When to Save vs When to Invest
Save (use HISA or term deposits) when:
- Time horizon < 3 years: A market downturn early in your saving period may not recover before you need the money
- Emergency fund: 3–6 months of expenses in cash — always. Market investments can fall 30%+ exactly when you need emergency funds
- Known near-term expense: House deposit, wedding, car, overseas trip within 1–3 years
- Low risk tolerance: If you cannot sleep at night with market volatility, a lower-return but certain option has real value
- Already maximising super: Superannuation is typically a superior long-term vehicle — max this before building a large taxable brokerage portfolio
Invest (shares/ETFs) when:
- Time horizon 5+ years: Long enough to ride out market downturns and recover
- Emergency fund is set: Investing is for money you genuinely don’t need short-term
- Super is being contributed to: Super provides tax-efficient compounding — but investing outside super builds accessible wealth
- Inflation concern: At current rates, investing offers significantly better long-term real returns than cash
The Hybrid Approach — Most Australians Should Do Both
A common framework:
- Emergency fund: 3–6 months expenses in HISA (never invest this)
- Short-term goals (< 3 years): HISA or term deposits
- Super contributions: Maximise employer + salary sacrifice (if beneficial)
- Long-term investing (5+ years): ASX ETFs (VAS, VGS, VDHG/DHHF for simplicity)

Frequently Asked Questions
Should I save or invest money in Australia? For money you need within 3 years: save (HISA or term deposit). For money you won’t need for 5+ years: consider investing in diversified shares or ETFs, which have historically delivered higher long-term returns than savings accounts — with higher short-term risk. General information only.
Is a high-interest savings account better than shares in Australia? Over short periods, a HISA is safer and more predictable. Over 10+ years, a diversified share portfolio has historically significantly outperformed savings accounts after inflation — but with meaningful volatility along the way. The correct answer depends on your time horizon and what the money is for.
What return can I expect from a savings account vs shares in Australia? As at 2026, the best HISA rates are around 5–5.5% (variable, conditions apply). Australian share portfolios (VAS) have historically returned approximately 9–10% total (including dividends) per annum over long periods — before tax. Real returns (after inflation) are approximately 3% (savings) vs 6–7% (shares) based on historical data. Past performance is not a reliable indicator of future performance.
