Building wealth by buying businesses in Australia
Nicholas Clunes, Founder12 August 2026 · 10 min read
There is a version of this topic that gets sold hard: buy businesses with none of your own money, stack them up, retire early. It is mostly nonsense, and the Australian lending market does not work that way. There is also a real version, which is slower, less exciting, and genuinely does build substantial wealth for people who do it carefully. This is about the second one.
Where the return actually comes from
Buying an established business produces a return from four separate places, and confusing them is the beginning of most bad decisions.
The four sources of return, and how reliable each one is
| Source | What it is | How much to count on it |
|---|---|---|
| Earnings, net of your own wage | What the business produces after paying a market rate for the work you do in it. | The core of it. If this is thin, nothing else rescues the deal. |
| Debt paydown | Every principal repayment converts borrowed money into owned equity. | Very reliable, and consistently underrated. It compounds quietly. |
| Operational improvement | Margin and efficiency gains you make after taking over. | Real but slower and harder than buyers expect. Never pay for it up front. |
| Multiple expansion | A larger, better-systemised business sells on a stronger multiple than a small owner-dependent one. | Genuine at scale, but only realised on exit, and only if you built the systems. |
Earnings, net of your own wage
- What it is
- What the business produces after paying a market rate for the work you do in it.
- How much to count on it
- The core of it. If this is thin, nothing else rescues the deal.
Debt paydown
- What it is
- Every principal repayment converts borrowed money into owned equity.
- How much to count on it
- Very reliable, and consistently underrated. It compounds quietly.
Operational improvement
- What it is
- Margin and efficiency gains you make after taking over.
- How much to count on it
- Real but slower and harder than buyers expect. Never pay for it up front.
Multiple expansion
- What it is
- A larger, better-systemised business sells on a stronger multiple than a small owner-dependent one.
- How much to count on it
- Genuine at scale, but only realised on exit, and only if you built the systems.
Notice that the second one requires nothing of you except that the business keeps trading. On a $900,000 facility over ten years, principal repayment alone converts something close to $60,000 to $70,000 a year of borrowed money into equity you own. Over a decade, with the business still running, that is most of a million dollars of wealth created by nothing more than paying the loan on time.
Notice also that the third one is the one buyers pay for most often and receive least reliably. Paying a premium today for improvements you intend to make yourself is paying the vendor for your own future work.
The honest arithmetic on one business
Take a business bought for $1.1 million, funded with $300,000 of your own money and an $800,000 facility over ten years.
A single acquisition, year one
| Line | Amount |
|---|---|
| Adjusted earnings | $340,000 |
| Less market salary for the owner's role | -$140,000 |
| Earnings available to service debt | $200,000 |
| Debt service, $800,000 over 10 years at 8.5% | -$119,000 |
| Of which principal, and therefore equity created | $52,000 |
| Cash left after debt service | $81,000 |
| Return on the $300,000 invested, cash only | 27% |
| Return including principal repayment | 44% |
Adjusted earnings
- Amount
- $340,000
Less market salary for the owner's role
- Amount
- -$140,000
Earnings available to service debt
- Amount
- $200,000
Debt service, $800,000 over 10 years at 8.5%
- Amount
- -$119,000
Of which principal, and therefore equity created
- Amount
- $52,000
Cash left after debt service
- Amount
- $81,000
Return on the $300,000 invested, cash only
- Amount
- 27%
Return including principal repayment
- Amount
- 44%
Illustrative, and before tax, working capital movements and capital expenditure, all of which are real. Cover here is roughly 1.68x before any stress testing.
That is a good business bought at a sensible price, and the return is strong. It is also a full-time job with $800,000 of debt attached, and both of those facts are part of the deal. Anyone presenting the 44% without the market salary line and the debt is not describing the same transaction.
How buyers actually fund the second one
This is where the strategy either compounds or stalls, and it is much less glamorous than it is usually described. There is no mechanism in Australian commercial lending for acquiring businesses without capital. What there is, is a sequence.
- The first business has to season. Most lenders want to see you run it successfully for at least two to three years before they will support a second acquisition, and they will want that history to be clean.
- Capacity comes from the consolidated position. A credit team looks at both businesses together, so the first one has to carry real surplus after its own debt service before it can support anything else.
- Debt paydown on the first business is what creates the equity for the second. This is the actual engine, and it takes years rather than months.
- Security matters. If the first business is unsecured and goodwill-heavy, the second acquisition is a harder file than if you own premises or hold other assets.
- Related businesses are far easier to fund than unrelated ones. A second site or a competitor in your sector reads as expansion. A business in an unrelated industry reads as distraction.
The practical shape of this, for most people who do it well in Australia, is a business every three to five years, not every year. Three businesses over fifteen years is a genuinely excellent outcome and would put most people well ahead of where a salary and a mortgage would have.
The risks, stated plainly
- Concentration. Your income, your capital and often your personal guarantees all sit in the same place, which is the opposite of how you would build a share portfolio.
- Personal guarantees. Almost all SME acquisition lending is guaranteed personally, and frequently secured against the family home. That is the real risk, and it does not appear in any return calculation.
- Illiquidity. You cannot sell a fifth of a business in a bad month. Exits take six to twelve months and depend on the market at the time.
- It is a job. Two businesses is usually two jobs until you have built the management layer, and building that layer costs margin.
- Overpaying for the first one. Every subsequent acquisition depends on the first one producing surplus. Pay too much and the whole sequence stalls before it starts.
What separates the people who do this well
- They test the earnings before they agree the price, every time, including on the deals they are excited about.
- They deduct a market wage for their own role and judge the return on what is left.
- They buy businesses that can run without them, or they build that capability deliberately in the first two years.
- They keep the financials clean from the start, because the next lender will read three years of history.
- They stay in one sector or one adjacent set of sectors, where their judgement is worth something and lenders can see why.
- They know their capacity before they start looking, so they are not negotiating on a business they were never going to be able to fund.

This is general information about how acquisition returns are structured, not personal financial advice, and it is not a recommendation to buy anything. What we can tell you is what a particular set of numbers supports, which is a narrower question and a considerably more useful one when there is a business in front of you.
