How many CBA shares do I need to buy for $10,000 of passive income?

Commonwealth Bank of Australia (ASX: CBA) has long been one of the most popular dividend shares on the ASX.

And with its enormous customer base, strong profitability, and history of returning billions of dollars to shareholders, it isn't hard to see why.

But how much would you need invested in Australia's largest bank to generate $10,000 in annual passive income? Let's take a look.

Why CBA remains popular

When Australians think about dividend shares, CBA is usually one of the first names that comes to mind.

And for good reason. The banking giant has a long history of paying shareholders twice a year, with fully franked dividends that can provide a valuable source of passive income.

But a good dividend history is only part of the story.

What investors like about CBA is its ability to generate billions of dollars in annual profits, giving management plenty of capacity to reward shareholders while retaining enough capital to support the business.

And if those profits continue growing over time, there should be opportunities for dividends to increase as well.

Of course, there are no guarantees. A weaker economy, rising bad debts, or pressure on lending margins could weigh on earnings and dividends.

Nevertheless, CBA arguably has a lot going for it as a long-term income investment, even if its dividend yield isn't among the highest on the ASX.

So, how much passive income could its shares generate over the next 12 months?

How many CBA shares would you need?

There's no getting away from the fact that generating $10,000 in annual passive income from CBA shares would require a sizeable investment.

After all, while CBA has a strong dividend history, its shares aren't offering a particularly high yield at current prices.

Based on its current share price of $149.29 and the consensus FY 2027 fully franked dividend forecast of $5.15 per share, investors are looking at a forward yield of approximately 3.45%.

That means an investor would need to own around 1,942 CBA shares to generate $10,000 in annual passive income, before considering any additional benefits from franking credits.

Buying that many shares today would cost approximately $289,921.

Could the passive income grow?

Looking further ahead, consensus estimates forecast CBA's earnings and dividends to increase in FY 2028.

The market is forecasting earnings per share of $6.86, which will be up from $6.67 in FY 2027.

This is expected to support an increase in annual dividends to $5.30 per share.

For someone holding 1,942 shares, that would lift annual passive income to approximately $10,293 in FY 2028.

These are only forecasts and actual dividends will depend on CBA's financial performance and economic conditions. But with its strong market position and history of returning profits to shareholders, CBA arguably remains one of the first ASX shares worth looking at when building a passive income portfolio.
