How much could a $300,000 ASX share portfolio pay in dividends?

For a lot of investors, the real appeal of the share market is not just watching a portfolio value move around on a screen. It’s the idea of generating a reliable income stream that can grow over time.

That’s where ASX dividend shares tend to shine. Unlike savings accounts or term deposits, shares offer the potential for two sources of return. There is income through dividends, and there is capital growth as the underlying businesses expand. On top of that, Australian investors benefit from franking credits, which can materially lift after-tax returns for many people.

With that in mind, let’s look at what a $300,000 ASX share portfolio could realistically deliver in dividends, using two different dividend yield scenarios.

A conservative income approach with blue chips

One way I could build an income-focused portfolio is to lean on large, established ASX shares with long dividend track records. Think businesses like BHP Group Ltd (ASX: BHP), Telstra Group Ltd (ASX: TLS), or Transurban Group (ASX: TCL).

These types of companies may not always offer the highest yields on the market, but they tend to provide a balance of income stability, resilience across cycles, and dividend growth over time.

A diversified portfolio of high-quality blue chips can often deliver a dividend yield of around 4% without taking on excessive risk. Importantly, much of that income is typically franked, which boosts its value for Australian investors.

Chasing higher yield comes with trade-offs

It is possible to push the income higher. A 5% dividend yield from an ASX portfolio is achievable, but it usually requires tilting toward higher-yielding sectors and stocks.

This might include infrastructure, REITs, energy infrastructure, or companies whose share prices have fallen, lifting the headline yield. While that can look attractive on paper, it comes with trade-offs.

Higher yields are not always sustainable. Sometimes they reflect genuine value. Other times, they are a warning sign that earnings are under pressure or that a dividend cut is a real possibility. This is what investors often refer to as a value or yield trap.

That doesn’t mean a 5% yield strategy is wrong. It just means the margin for error is smaller, and portfolio construction becomes more important.

So, how much income are we really talking about?

Let’s now answer the key question.

At a 4% dividend yield, a $300,000 ASX share portfolio would generate around $12,000 per year in dividends. That works out to roughly $1,000 per month before franking credits.

At a 5% dividend yield, the same portfolio would generate about $15,000 per year in dividends, or roughly $1,250 per month before franking credits.

Foolish Takeaway

The key takeaway for me is that dividend income from ASX shares is flexible. Investors can dial risk up or down depending on their needs, time horizon, and tolerance for volatility.

A $300,000 portfolio is not about getting rich overnight. But when invested thoughtfully, it has the potential to deliver a growing income stream that beats cash over time, while also offering capital growth along the way.

That combination is what I think makes ASX dividend investing so compelling for long-term investors.
