For many investors, the idea of becoming a millionaire feels out of reach, especially if you're starting small. But thanks to the power of compounding, even modest, consistent investments can grow into something substantial over time.
Let's explore how investing just $500 per month in ASX shares could grow to $1 million, and the strategies that can help you get there.
The power of compounding
Compounding is what happens when your returns earn returns. It is a snowball effect: the longer you invest, the faster your portfolio can grow, even if your contributions remain the same.
If you invest $500 per month and achieve an average 10% annual return (which isn't guaranteed but is achievable over long periods with a diversified, growth-focused portfolio), your investment could reach $1 million in about 30 years.
Here's how the growth might look:
- After 10 years: $100,000
- After 20 years: $362,000
- After 30 years: $1 million
This shows why time in the market is more important than timing the market — the real growth comes in the later years as compounding accelerates.
The ASX shares for that kind of growth
To target a 10% annualised return, investors need to look beyond term deposits or defensive assets and lean towards high-quality growth shares or ETFs.
This might mean diversified ASX ETFs like the Vanguard Australian Shares Index ETF (ASX: VAS) for exposure to the top 300 local companies or the Betashares Nasdaq 100 ETF (ASX: NDQ), which holds tech leaders like Apple, Microsoft, and Nvidia, for global growth.
In addition, individual growth shares can help supercharge your returns when included in a balanced portfolio. This could mean ASX shares like Pro Medicus Ltd (ASX: PME), WiseTech Global Ltd (ASX: WTC), and Xero Ltd (ASX: XRO).
The key is diversification — combining broad-market ETFs with a few world-class businesses that can grow earnings year after year.
Stay consistent
Markets will rise and fall along the way, but the only way to benefit from compounding is to stay invested. By continuing to contribute through the ups and downs, you not only grow your portfolio faster but also buy more shares when prices are low.
If you can increase your monthly contributions over time — say, from $500 to $750 or $1,000 as your income grows — you could hit $1 million even faster.
Foolish takeaway
Becoming a millionaire on the ASX doesn't require a huge lump sum or a winning lottery ticket. With $500 per month, a focus on quality growth investments, and the patience to let compounding do the heavy lifting, it is possible to turn steady contributions into $1 million over time.
