How I’d invest monthly savings to generate over $50,000 passive income

Building a meaningful passive income doesn’t usually happen overnight. Yet with time, discipline, and the power of compounding, even relatively modest monthly savings can snowball into something far more substantial.

The key lesson is simple: the earlier and more consistently you invest, the greater the long-term potential. Monthly contributions may feel small at first, but when they’re reinvested and allowed to compound over decades, the results can be powerful.

Rather than chasing quick wins or headline yields, I’d focus on building a diversified income portfolio designed to grow steadily and sustainably.

Working backwards from a $50,000 income goal

Let’s start with the maths.

If an investor wanted to generate $50,000 per year in dividends and distributions, a useful starting assumption is a 3% portfolio yield. That’s deliberately conservative and avoids relying on unusually high payouts.

At a 3% yield:

• $50,000 ÷ 3% = $1.67 million portfolio value

That figure can sound daunting at first glance. 

But it’s important to remember two things.

First, this is the end point, not the starting line. Most of the heavy lifting is done by compounding over time. Second, the yield itself isn’t static. Many quality income investments aim to grow distributions over time, meaning the income can rise even if the portfolio value stays the same.

For simplicity, this calculation does not include franking credits. In reality, franking can materially lift after-tax income for Australian investors. The benefit will vary depending on the mix of shares and funds held, but for portfolios tilted towards Australian equities, franking is typically a tailwind rather than a headwind.

Why starting early matters more than starting big

One of the biggest advantages an investor can give themselves is time.

Regular monthly investing achieves three things at once:

• It smooths out market volatility
• It builds the habit of saving and investing
• It maximises the compounding runway

Increasing contributions earlier in life can have an outsized impact on the eventual outcome. Even small increases in monthly savings, made early, can reduce the pressure to contribute far more later on.

Over decades, capital growth, reinvested income, and incremental increases in savings can work together in a way that’s difficult to replicate with lump-sum investing alone.

A simple foundation using diversified income investments

For a core portfolio, I’d keep things straightforward.

One option is the Vanguard Australian Shares High Yield ETF (ASX: VHY), which provides exposure to a diversified basket of Australian companies with above-average dividend yields. It spreads risk across sectors and offers access to franked income without needing to pick individual stocks.

To complement that, the L1 Long Short Fund Ltd (ASX: LSF) offers a different income profile. As a listed investment company, it aims to generate returns across market cycles, with the ability to smooth dividends using profit reserves. This can add diversification away from traditional long-only equity income.

Used together, funds like these can form a simple base designed to deliver income while reducing reliance on any single company or sector.

Adding quality businesses for dividend growth

For investors willing to be more hands-on, adding a selection of individual ASX dividend shares can provide another layer of income growth.

A long-standing example, Washington H. Soul Pattinson and Co. Ltd (ASX: SOL) has built a reputation for steady dividend increases across multiple decades, supported by a diversified investment portfolio.

For more defensive income, Telstra Group Ltd (ASX: TLS) remains a widely followed option. It is essentially a monopoly on Australian telecommunications, so predictable cash flows have historically supported ongoing shareholder distributions.

Meanwhile, Jumbo Interactive Ltd (ASX: JIN) shows how niche digital businesses can translate recurring customer activity into growing cash returns for investors.

These types of companies can complement ETFs by introducing the potential for dividend growth over time.

Bringing it all together

Generating $50,000 a year in passive income isn’t about finding a single perfect stock or timing the market just right. It’s about building a diversified portfolio, contributing regularly, reinvesting early income, and letting time do the work.

The mix of ETFs and quality businesses will differ from investor to investor. So will the pace of contributions and the eventual yield. But the underlying principle remains the same: consistent investing, compounded over long periods, can turn monthly savings into a powerful income stream.

It may not be exciting week to week. But over decades, it can be remarkably effective.
