How to make $20,000 of passive income from ASX shares

When people talk about passive income from shares, the conversation often jumps straight to dividend yields and payout schedules.

But that misses the bigger picture. The most reliable way to generate meaningful, sustainable passive income from ASX shares is not to chase income first.

Here's one way to think about building a $20,000 annual passive income stream.

Start thinking in ownership

Passive income from ASX shares is simply your share of business profits. The more high-quality businesses you own, the larger your slice becomes.

Instead of looking for the biggest dividend yields today, a better starting point is looking to build ownership in great businesses.

For most investors, this means spending years focusing on portfolio growth, not income. High-quality ASX shares reinvesting profits tend to compound faster than high-yield stocks that distribute most of their cash.

How much do you need

To generate $20,000 a year in passive income at an average 5% yield, you need a portfolio worth $400,000.

That number can sound intimidating, but it needn't be.

In the accumulation phase, most investors are better off owning a mix of growth-focused ASX shares and broad ETFs.

Reinvesting all dividends during this phase quietly accelerates compounding. That's because you are buying more shares without adding new capital, which increases future income potential without effort.

Over 10 to 20 years, this approach can dramatically increase the size of the portfolio compared to income-first strategies.

Which ASX shares?

Investors may want to focus on ASX shares that have strong business models and positive long term growth outlooks.

Companies that tick these boxes include Goodman Group (ASX: GMG), ResMed Inc. (ASX: RMD), TechnologyOne Ltd (ASX: TNE), and Xero Ltd (ASX: XRO).

They all have the potential to deliver strong returns over the next decade (and beyond), which could help Aussie investors build up the capital they need to then start generating meaningful passive income.

Speaking of which, starting at zero, if you were able to invest $500 a month into ASX shares, you would arrive at a $400,000 portfolio in 21 years if you averaged a 10% per annum return.

If you want to get there sooner, increase your monthly contributions. $1,000 a month would take 15 years, all else equal.

Foolish takeaway

The real secret to earning $20,000 of passive income from ASX shares is not finding the perfect dividend stock. It is building a portfolio large enough that average yields do the work for you.

Once you reach that point, income generation will be surprisingly easy.
