Key points

  • Small, regular investments in ASX ETFs can substantially grow wealth over time, as demonstrated by investing $200 monthly potentially reaching over $40,000 in 10 years at a 10% annual return.
  • Selecting high-quality, broad-based ETFs like Vanguard Australian Shares Index and iShares S&P 500 balances local and global exposure, enhancing portfolio stability and growth.
  • Long-term consistency with such investment habits could yield around $150,000 in 20 years or $415,000 in 30 years, leveraging the power of compounding to transform modest savings into significant wealth.

One of the biggest misconceptions in investing is that you need a huge amount of money to get started.

The reality is that even modest savings can compound into something substantial if you use the right approach to investing.

Exchange-traded funds (ETFs) listed on the ASX are a simple and effective way to make this happen. With a single trade, you gain exposure to dozens or even thousands of shares, which spreads your risk and taps into long-term growth opportunities.

Start small

Imagine you can put aside $200 a month into a diversified ASX ETF. That's less than the cost of a daily coffee habit in the Sydney CBD. Over time, thanks to the power of compounding, those small investments can snowball into a sizeable portfolio.

At an average return of 10% per annum (not guaranteed, but in line with historical market averages), your $200 monthly contributions would grow to more than $40,000 after 10 years — despite only contributing $24,000.

Choose the right ASX ETFs

The key is to focus on high-quality, broad-based ETFs that provide long-term exposure to strong markets and sectors.

For example, the Vanguard Australian Shares Index ETF (ASX: VAS) tracks the top 300 local shares, giving you instant access to blue chips like Rio Tinto Ltd (ASX: RIO), Treasury Wine Estates Ltd (ASX: TWE), and Woolworths Group Ltd (ASX: WOW).

On the global side, the iShares S&P 500 ETF (ASX: IVV) invests in the 500 largest U.S. stocks, including Apple (NASDAQ: AAPL) and Microsoft (NASDAQ: MSFT). By combining both, you can balance local stability with global innovation.

Play the long game

The real magic happens when you keep going. Extend those $200 monthly investments out to 20 years, and your portfolio could be worth almost $150,000. Stick with it for 30 years, and you're looking at around $415,000 — from contributions totalling just $72,000.

This is the power of compounding in action: the longer you stay invested, the harder your money works for you. And if anything is going to work hard, let it be your money.

Foolish takeaway

Turning small savings into big wealth doesn't require luck, special skills, or huge capital upfront. It comes down to consistency, patience, and the discipline to keep investing in quality ASX ETFs through the ups and downs of the market.

Start small today, and in a few decades, you could be looking at a portfolio big enough to change your financial future.
