Key points

  • Achieving $20,000 in extra income annually is possible through disciplined investing in ASX shares, focusing on dividends and long-term growth.
  • Consistent investments and the power of compounding can grow a portfolio to the needed size for generating significant passive income.
  • Prioritise high-quality dividend-paying shares or dividend-focused ETFs to build sustainable income without the need for risky strategies.

Earning an extra $20,000 a year sounds like a side hustle dream. But instead of taking on more work or sacrificing weekends, it could be possible to generate that additional passive income through disciplined investing in ASX shares.

But it doesn't happen overnight. It takes time, consistency, and patience.

Here's how to get started.

Think long-term

The key to generating meaningful passive income from ASX shares isn't timing the market. It is time in the market.

Dividends and compounding returns are what drive wealth creation, so focus on steady, sustainable growth rather than chasing fast gains.

If your goal is to earn an extra $20,000 per year, you will first need to build a portfolio big enough to produce that level of passive income. At an average dividend yield of 5%, you'd need a portfolio worth around $400,000 to reach that target.

That may sound like a lot but remember that investing is a gradual process. Many Australians hit that milestone by starting small and contributing consistently over years, not months.

Invest regularly

Let's say you can afford to invest $1,000 of your salary per month into a portfolio of high-quality ASX shares.

If you were able to achieve an average 10% annual return, which is not guaranteed but a reasonable long-term target, you could reach your goal sooner than you might think.

After 15 years, you would have a portfolio valued at roughly $400,000, which is enough to generate that $20,000 annual passive income target through dividends.

Focus on quality dividend payers

Not all shares are created equal when it comes to passive income. When the time comes, you will want to look for ASX shares with consistent earnings, strong balance sheets, and a history of paying (and ideally growing) dividends.

Some examples today include Transurban Group (ASX: TCL), which is a toll road operator with predictable, inflation-linked cash flows, and Coles Group Ltd (ASX: COL), which is a defensive consumer staple.

Alternatively, dividend-focused ETFs such as the Vanguard Australian Shares High Yield (ASX: VHY) can provide diversified exposure and remove the need to pick individual stocks. This ETF invests in ASX shares which are forecast by brokers to have higher than average dividend yields.

Foolish takeaway

Building an extra $20,000 a year in income through investing doesn't require luck, day trading, or risky bets. It requires time, patience, and consistency.

If you start small, invest regularly, reinvest your dividends, and focus on quality, the share market can become a genuine second income.
