Key points

  • Building a $100,000 ASX share portfolio for passive income involves targeting a realistic income yield, such as 5%, to generate about $5,000 annually without depleting capital.
  • Diversification with quality ASX dividend shares and income-focused ETFs is crucial, combining reliable stocks like Telstra and Coles with funds like Vanguard Australian Shares High Yield ETF for broad exposure.
  • Allowing the portfolio to grow in value and dividend payouts can significantly increase passive income over time, reaching approximately $8,150 annually in ten years with capital growth.

The dream of financial freedom for many Aussies comes down to one simple goal: creating an income stream that pays without having to work for it.

The good news is that the ASX is one of the best markets in the world for doing just that, thanks to its dividend culture and the benefits of franking credits.

So, how can a $100,000 ASX share portfolio be converted into passive income? Here are three steps to take:

Step 1: Decide on a target

The first step is to work out what sort of income you want to generate. At an average dividend yield of around 5%, which is achievable with a mix of quality dividend shares and ETFs, a $100,000 portfolio could deliver about $5,000 a year.

That's roughly $416 per month in passive income, without touching your capital.

Step 2: Build your portfolio

While chasing high yields might be tempting, the real key to sustainable passive income is diversification. That means blending individual dividend stocks with ETFs designed for income.

Quality ASX dividend shares like Telstra Group Ltd (ASX: TLS), Transurban Group (ASX: TCL), and Coles Group Ltd (ASX: COL) would be worth considering. These are established businesses with reliable cash flows and growing dividends.

In addition, funds like the Vanguard Australian Shares High Yield ETF (ASX: VHY) and the Betashares Global Royalties ETF (ASX: ROYL) spread your money across dozens of income-producing ASX shares, reducing the risk of relying on just a few names.

With these types of ETFs, investors also gain access to sectors and geographies they might otherwise miss — from Australian banks and miners to global royalty businesses in music, energy, and technology.

Step 3: Grow your passive income

A common misconception is that passive income stays flat. In reality, quality ASX shares increase their dividends as their profits rise, and ETFs naturally capture that growth through their holdings.

If your $100,000 portfolio grows at around 5% per year in capital value, while also paying a 5% yield, the income can rise steadily. In 10 years, your portfolio might be worth around $163,000, and the income closer to $8,150 annually. That's a big lift without adding a cent of new money.

Foolish takeaway

Turning a $100,000 ASX share portfolio into passive income is about more than just buying the highest yields. By focusing on quality ASX shares, diversifying with income-focused ETFs, and giving your investments time to grow, it is possible to build an income stream that not only pays today but grows every year into the future.
