How many BHP shares do I need to buy to earn $100 a week in passive income?

With FY 2026 dividends up 41.6% from the prior financial year, BHP Group Ltd (ASX: BHP) shares have jumped back onto passive income investors' radars.

Atop the welcome passive income boost, BHP has also delivered some outsized capital gains.

Trading at $60.04 apiece on Monday, shares in the S&P/ASX 200 Index (ASX: XJO) mining giant have surged a remarkable 48% in 12 months.

That's seen the Aussie miner's market cap leap to just under $306 billion. And earlier this year, it saw BHP retake the mantle from Commonwealth Bank of Australia (ASX: CBA) as the biggest company on the ASX.

So, how about that $100 a week – or $5,200 a year – in passive income?

We'll crunch those numbers below in a tick.

But before we do, keep in mind that the dividend yields you generally see quoted are trailing yields. These are, by their nature, backward-looking.

Future BHP dividend payouts could be higher or lower depending on a range of macroeconomic and company-specific factors. For BHP, that includes things such as variable weather conditions and future copper and iron ore prices.

With that said…

Drilling into BHP shares for $100 a week in passive income

BHP paid a fully-franked interim dividend of $1.039 a share on 26 March.

Management then declared a final fully-franked dividend of $1.38 a share when the ASX 200 mining stock reported its full-year FY 2026 results on 18 August. That's up 50.2% from the previous final dividend payout.

It's a bit too late to grab that latest passive income payout, as BHP shares traded ex-dividend on 3 September. If you held the stock at market close on 2 September, you can expect to receive that boosted dividend next week, on 23 September.

For the full year, then, BHP paid out a total of $2.419 a share in fully-franked dividends.

At the recent share price, this sees the stock trading on a fully-franked trailing yield of 4%.

And to earn $100 a week, or $5,200 a year, in passive income, you'd need to buy $2,150 BHP shares today.

At the recent share price, that represents an investment of $129,086.

Now, I realise that's a big investment to make all in one go.

But that's okay.

Investing is a long game.

You can always buy a smaller number of BHP shares on a regular basis, and you'll reach your $100 weekly passive income goal in good time.
