At a Glance

How much will my investments grow in Australia?

Investment growth in Australia benefits from franking credits on Australian shares, 50% CGT discount for assets held 12+ months, and super's 15% earnings tax rate. Our compound interest calculator projects growth with these Australian tax advantages factored in.

Quick Answer

How does compound interest work in Australia?

Compound interest in Australia applies across investment vehicles including superannuation (taxed at 15% on earnings), ETFs, managed funds, and term deposits. Inside super, the combined effect of 11.5% employer contributions, salary sacrifice, and 15% earnings tax creates powerful long-term growth. Outside super, franking credits on Australian shares provide an additional return premium over international investments.

Frequently Asked Questions

What is a realistic investment return in Australia?

The ASX 200 has historically returned 8-10% annually including dividends. A diversified portfolio of Australian shares, international shares, and bonds might return 6-8% over the long term. Term deposits currently offer 4.5-5.5%. Property has historically returned 6-8% annual growth in major cities.

How are investments taxed in Australia?

Capital gains on assets held 12+ months receive a 50% CGT discount (effectively halving your gain). Dividends from Australian companies include franking credits. Investment income is added to your assessable income and taxed at your marginal rate plus Medicare Levy. Superannuation investment earnings are taxed at 15% with CGT at 10% for held assets.

What is the maximum super contribution in Australia?

The concessional (before-tax) cap is $30,000 for 2025-2026, including employer super guarantee contributions (11.5%) and salary sacrifice amounts. The non-concessional (after-tax) cap is $120,000, or up to $360,000 over 3 years under the bring-forward rule (if your total super balance is under $1.9M).

How does salary sacrifice into super work?

Salary sacrifice involves your employer diverting pre-tax salary into your super fund. This reduces your taxable income and is taxed at only 15% in the super fund (vs your marginal rate up to 45%). Combined with employer contributions, the total must stay under the $30,000 concessional cap.

What is dollar-cost averaging?

Dollar-cost averaging means investing a fixed amount regularly regardless of market conditions. You buy more units when prices are low and fewer when high, reducing the impact of market timing. This strategy works well for long-term investors in Australia using regular contributions to an ETF or managed fund.

What are ETFs and how do they work?

Exchange Traded Funds (ETFs) are baskets of securities that trade on the ASX like individual shares. Popular Australian ETFs include VAS (ASX 300), VGS (global shares), and A200 (top 200 ASX companies). ETFs offer instant diversification with low fees (0.04-0.30% MER) and are tax-efficient.
