Compound Annual Growth Rate (CAGR): A Guide for Australian Investors 2025

As Australians look to grow their wealth in a rapidly changing economic climate, understanding how investments perform over time is crucial. Enter the Compound Annual Growth Rate—better known as CAGR. While the term might sound technical, it’s a powerful tool that can demystify returns and help you compare investment opportunities on an even playing field.

What is CAGR and Why Does It Matter?

CAGR stands for Compound Annual Growth Rate. It’s a formula that measures the mean annual growth rate of an investment over a specific period, assuming profits are reinvested each year. In essence, CAGR smooths out the highs and lows to show the steady rate your investment would need to grow to reach its final value.

Here’s why CAGR is so useful for Australians in 2025:

• Straightforward comparison: Whether you’re weighing up superannuation funds, ETFs, or property investments, CAGR offers a single, comparable growth rate.

• Ignores short-term volatility: Unlike year-on-year returns, CAGR isn’t skewed by one-off market events. It focuses on the big picture.

• Relevant for long-term goals: Superannuation, children’s education savings, and home deposits benefit from understanding long-term growth rates.

How to Calculate CAGR: The 2025 Formula

The basic CAGR formula remains unchanged in 2025:

CAGR = (Ending Value / Beginning Value) ^ (1 / Number of Years) – 1 Let’s put it into an Australian context:

• Example: You invested $10,000 in an ASX200 ETF at the start of 2020. By the start of 2025, it’s worth $16,105.

Plug into the formula:

CAGR = ($16,105 / $10,000) ^ (1/5) – 1

CAGR ≈ 10% per year

This means your investment grew at an average rate of 10% per year, compounded, over five years—even if individual years saw swings up or down.

Many online calculators and superannuation platforms now provide CAGR calculations, making it easier for Australians to compare fund performance in 2025. Still, knowing the underlying math helps you interpret results and spot marketing spin.

Where CAGR Shines (and Where it Doesn’t)

CAGR is a staple in investment reporting, but it’s not a cure-all. Here’s where it excels for Australians in 2025:

• Comparing managed funds and ETFs: With recent APRA super fund performance benchmarks, using CAGR over 3, 5, or 10 years helps investors see which options are truly delivering.

• Property investment: In a market where annual growth rates swing wildly, CAGR smooths out the results. For example, CoreLogic’s 2025 housing data shows some cities had negative years followed by double-digit rebounds. CAGR cuts through the noise.

• Business growth: Australian SMEs raising capital often present revenue CAGR to investors, showing sustainable expansion rather than just one-off spikes.

However, CAGR has its limitations:

• Ignores volatility: A portfolio with huge ups and downs may have the same CAGR as a steady performer, but the risk profile is very different.

• Assumes reinvestment: In real life, you might withdraw dividends or rent. CAGR works best when all earnings are reinvested.

• Doesn’t reflect timing: If you make extra contributions or withdrawals, you’ll need more advanced metrics like IRR (Internal Rate of Return).

Making Smarter Decisions with CAGR in 2025

With rising interest rates, ongoing market volatility, and new regulatory scrutiny of fund performance, Australians are more focused than ever on making their money work harder. CAGR is a valuable metric, but it’s best used as part of a broader toolkit.

• When comparing super funds, check both their 5- and 10-year CAGRs and their annual volatility or risk ratings.

• For direct shares or ETFs, use CAGR alongside dividend yields and franking credits to get a complete picture of returns.

• If you’re looking at property, ask agents for long-term CAGR data, not just recent price spikes.

In 2025, platforms like the ATO’s YourSuper comparison tool and ASIC’s Moneysmart make it easier to access these figures. Still, understanding CAGR empowers you to cut through marketing fluff and focus on what really matters: consistent, sustainable growth.

The Bottom Line

CAGR is more than just a formula—it’s a lens that brings clarity to investment performance. By focusing on long-term, compounded growth, Australians can make more confident decisions, whether they’re building super, investing in property, or growing a business. As financial markets and products evolve in 2025, mastering metrics like CAGR will help you stay ahead of the curve.
