Superannuation is a great investment tool for building wealth for retirement.
Your superannuation offers the opportunity to receive concessional tax treatment, and you get the chance to grow your balance through the power of compounding.
Once you retire and move into the pension phase, your super can also provide a regular stream of passive income.
But how much superannuation do you need to accumulate to generate a passive income high enough to live comfortably on?
Here's a breakdown, using a target of $8,000 a month in passive income as an example.

How much do I need in my superannuation to get a $8,000 monthly passive income?
First you need to work out what $8,000 per month translates to over the year.
So, $8,000 x 12 = $96,000.
Then you'll need to divide your annual passive income ($96,000) by the dividend yield of your overall portfolio.
For example, $96,000 ÷ 3% = $3.2 million (that's the superannuation portfolio size you'd need).
The trick is that the answer varies significantly depending on the dividend yield of your portfolio.
For example, a superannuation portfolio with a dividend yield of around 6% only needs to be around half the size of one with a dividend yield of around 3% to generate the same level of passive income.
Ok, so what balance do I need for a portfolio yielding 4%, 5% and 6%?
Say your overall portfolio has a slightly higher dividend yield of around 4%, you'll need a balance of around $2.4 million to earn the same $96,000 per year (equivalent to $8,000 per month) in passive income. That looks like: $96,000 ÷ 4% = $2.4 million.
Then, if the yield of your portfolio is around 5%, your superannuation balance would need to be closer to $1.9 million to earn the same dividend income.
For a 6% yielding portfolio, you'd need a balance of closer to $1.6 million to earn the same amount.
And so on…
Note that most ASX dividend shares pay dividends on a semi-annual or yearly basis. This means that while you could target the equivalent of $8,000 per month in passive income, you won't actually receive the money on a month-by-month basis, but instead in a lump sum.
What ASX shares can I buy that yield 3-6%?
There are a huge number of ASX dividend shares available for superannuation investment.
Here are some of my favourites.
For ASX shares yielding around 3% I'd pick large-cap blue-chips like BHP Group Ltd (ASX: BHP), Rio Tinto Ltd (ASX: RIO), Woolworths Group Ltd (ASX: WOW), or Macquarie Group Ltd (ASX: MQG).
ASX shares yielding around 4% would be something like banking giants National Australia Bank Ltd (ASX: NAB) or ANZ Group Holdings Ltd (ASX: ANZ), Telstra Group Ltd (ASX: TLS), or Nick Scali Ltd (ASX: NCK).
For 5% yielding ASX shares, my picks would be Woodside Energy Group Ltd (ASX: WDS), Sonic Healthcare Ltd (ASX: SHL), TPG Telecom Ltd (ASX: TPG) or Servcorp Ltd (ASX: SRV).
And then for 6% yielding options, I'd opt for something like Metcash Ltd (ASX: MTS), Origin Energy Ltd (ASX: ORG), or Dexus (ASX: DXS).
