Most people assume wealth is built by starting big.
In reality, it usually starts quietly. A decision to invest consistently. A habit that runs in the background. Over time, those small actions can snowball into something meaningful.
If you start from zero, invest $500 a month, and achieve an average return of 10% per annum, building a $250,000 ASX share portfolio is entirely realistic. Here is how you could approach it.
The timeline
At a 10% annual return, investing $500 every month allows compounding to do its thing.
Over roughly 17 years, those monthly contributions can grow into a portfolio valued at about $250,000.
The early years can feel slow. Progress looks modest at first, and it can be tempting to lose patience. But as your portfolio grows, the compounding effect becomes far more noticeable, and the curve starts to steepen.
Focusing on quality ASX shares
The most reliable long-term results tend to come from owning high-quality ASX shares with strong competitive positions and positive long term growth outlooks. These are the companies that can keep growing through different economic environments.
Examples of the types of businesses that fit this description include CSL Ltd (ASX: CSL) in plasma therapies, Cochlear Ltd (ASX: COH) in hearing devices, and Goodman Group (ASX: GMG) in logistics and digital infrastructure. Defensive shares like Woolworths Group Ltd (ASX: WOW) and diversified leaders such as Macquarie Group Ltd (ASX: MQG) can also play an important role.
Don't forget to reinvest dividends
The Australian share market is one of the most generous in the world when it comes to dividends.
But you will want to remember to reinvest those dividends when you receive them. After all, if you were to generate a 3% dividend yield across your portfolio and didn't reinvest, you would be slowing down the compounding process meaningfully.
For example, $500 a month compounding by 7% per annum would only be approximately $190,000 after 17 years. That's $60,000 less than if you had reinvested the dividends.
Once your portfolio reaches a meaningful size, you could choose to start using dividends as income. But if your aim is to build wealth quickly, reinvestment gives compounding the best chance to work.
Foolish takeaway
Building a $250,000 ASX share portfolio from nothing does not require perfect decisions or special insight.
By investing $500 a month into quality ASX shares and earning an average return of 10% per annum, that goal can be reached in around 17 years.
You just need a combination of patience, discipline, and time.
