Investment Returns Calculator – Australian Growth & Franking
Project your investment growth using Australian market benchmarks. This tool factors in the unique benefits of franking credits on the ASX, the impact of capital gains discounts, and the long-term compounding effects of the Australian Superannuation system.
Expert Guidelines
The 'Franking Credit' Advantage
Australian companies often pay dividends with franking credits, representing tax already paid at the corporate level. For Australian investors, these credits can add an extra 1-2% to your 'effective' annual return. When using this calculator, ensure you factor in these imputation credits, as they make the ASX one of the highest-yielding markets globally and are a pillar of wealth creation for many Australian retirees.

ASX 200 Historical Performance
The S&P/ASX 200 Accumulation Index, which includes reinvested dividends, has historically returned around 9-10% per annum over the last 30 years. ASIC Moneysmart highlights that while past performance is not a guarantee of future results, consistent investing in a diversified portfolio of Australian and international shares is the most effective way to beat inflation and grow your wealth in the long run.

Superannuation as a Wealth Engine
Superannuation is the primary investment vehicle for most Australians. Because returns inside 'Super' are taxed at a maximum of 15% (compared to your marginal rate outside), the compounding effect is significantly higher. Our tool allows you to simulate your returns inside the Super environment to see how much faster you can reach your retirement target by maximizing your concessional contributions.

Frequently Asked Questions
What return should I expect on my Australian portfolio?
Most Australian financial planners use a long-term 'real' return (after inflation) of 4-5% for balanced funds and 6-7% for high-growth equity funds. When calculating your future wealth, it's safer to use conservative figures to ensure you don't fall short. This calculator provides a range of options based on historical Australian and global market cycles.
How do investment fees affect my returns in Australia?
Fees are the single biggest drag on investment performance. A 1% difference in fees can result in hundreds of thousands of dollars less in your final portfolio over 30 years. In Australia, the 'Your Future, Your Super' performance test now benchmarks funds to ensure they aren't charging too much for underperformance. Our calculator helps you see the impact of these management fees on your net wealth.
Is property a better investment than shares in Australia?
Both have historically performed well. Property offers leverage (borrowing to invest) but higher entry and exit costs (stamp duty and agent fees). Shares offer higher liquidity and franking credits. This tool allows you to compare the growth of a lump-sum investment in the ASX versus a property deposit, helping you decide which asset class fits your Australian financial strategy.
How to Use This Calculator
This investment returns calculator uses the compound interest formula to project the growth of your wealth over time. Enter your initial investment, regular contributions, expected rate of return, and investment period to see how much your money can grow.
- Initial Investment: How much you have to invest today
- Regular Contribution: Amount you plan to add periodically
- Rate of Return: Expected annual return (7% is historical market average)
The Power of Compound Interest
Albert Einstein reportedly called compound interest "the eighth wonder of the world." Whether true or not, the concept is genuinely powerful. Compound interest makes your money grow exponentially because you earn returns not just on your original investment, but also on the accumulated returns.
The Rule of 72
Divide 72 by your annual rate of return to estimate how many years it will take to double your money. For example: at 7% return, your money doubles every ~10 years (72 ÷ 7 = 10.3 years).
Example: $10,000 Over 30 Years
| Rate | Final Value |
|---|---|
| 5% | $43,219 |
| 7% | $76,123 |
| 10% | $174,494 |
| 12% | $299,599 |
Time Impact
Starting early is crucial. Investing $200/month from age 25 to 65 at 7% results in $525,000. Waiting until 35 to start results in only $244,000 - less than half!
Historical Returns by Asset Class
Long-Term Average Returns
- Stocks (S&P 500): ~10% annually (7% inflation-adjusted)
- Bonds: ~5% annually
- Real Estate: ~8-10% including rent
- Savings/CDs: ~2-4% annually
Important Considerations
- • Past returns don't guarantee future performance
- • Inflation reduces real returns (subtract 2-3% for real returns)
- • Fees and taxes further reduce returns
- • Diversification reduces risk without sacrificing returns

Frequently Asked Questions
What rate of return should I use?
For stocks, 7% (inflation-adjusted) or 10% (nominal) is a reasonable estimate based on long-term historical returns. Be conservative - it's better to be pleasantly surprised than disappointed.
How often should I invest?
Monthly is ideal for most people. It matches income cycles, builds discipline, and maximizes the benefit of dollar-cost averaging. Automate to remove emotions from the equation.
How does compounding frequency affect my returns?
More frequent compounding results in slightly higher returns. At 10% annually, monthly compounding yields 10.47% effective return, while annual compounding stays at 10%. The difference is small but adds up over decades.
