How much wealth could I build by investing $500 a month into ASX shares?

Not everyone can afford to invest tens of thousands of dollars into ASX shares. But that doesn’t matter because you don’t need to do that to build wealth in the share market.

In reality, consistency often matters far more than the size of the investment.

Investing $500 a month into ASX shares may not sound like it could become something meaningful. But you would be wrong.

The power of consistency

Putting aside $500 every month means investing $6,000 a year. That alone adds up steadily, but the real benefit comes from staying invested through different market conditions.

Some months, you will invest when prices are rising. Other months, you will invest when markets are under pressure. Rather than trying to time those moves, regular investing smooths out the journey and removes emotion from the process. This is what we call dollar-cost-averaging.

This approach also helps investors stay committed. A simple monthly plan is far easier to maintain than trying to decide when to invest larger sums.

Building wealth with ASX shares

To provide some context, let’s assume I can invest $500 per month in ASX shares and earn a long-term average return of 9% per year. 

That is broadly in line with historical share market returns over long periods, although actual returns will vary year to year.

Here is what that could look like:

• After 10 years, my ASX share portfolio could be worth around $95,000
• After 20 years, my portfolio could grow to roughly $330,000
• After 30 years, it could reach more than $850,000 in value

None of this requires picking perfect ASX shares or timing the market. It stems from a combination of time, consistency, compounding, and a well-balanced portfolio comprising strong companies. This could include shares such as Macquarie Group Ltd (ASX: MQG), Sigma Healthcare Ltd (ASX: SIG), Wesfarmers Ltd (ASX: WES), and Commonwealth Bank of Australia (ASX: CBA).

Flexibility along the way

Investing $500 a month also gives investors flexibility. Contributions can be increased when income rises or reduced temporarily if circumstances change.

More importantly, it builds confidence. Watching a portfolio grow through regular contributions helps reinforce good habits and makes long-term investing feel achievable rather than intimidating.

Foolish Takeaway

Investing $500 a month into ASX shares is not about getting rich quickly. It is about building momentum over time.

With patience and a reasonable long-term return, that steady habit can grow into hundreds of thousands of dollars. You do not need to start with a fortune. You just need consistency and time.
