What Adjusted EBITDA Actually Means When You Sell Your Business

You've probably heard that buyers value businesses using EBITDA multiples. What most business owners don't realise is that the EBITDA number buyers use to calculate your price has almost nothing to do with the EBITDA on your financial statements.

They adjust it. Heavily. And the difference between reported EBITDA and adjusted EBITDA is often the difference between a $2 million exit and a $3 million exit—or between accepting an offer and walking away from the table entirely.

This isn't a technicality buried in due diligence. It's the single most important number in your sale process. If you don't understand what gets adjusted, why, and how to defend those adjustments, you're negotiating blind.

What EBITDA actually is (and why buyers start there)

EBITDA stands for Earnings Before Interest, Tax, Depreciation, and Amortisation. In plain terms, it's a measure of your business's operating profitability, stripped of financing decisions, tax structures, and accounting conventions.

The reason buyers use EBITDA—rather than net profit—is because it isolates the core earnings power of your business, independent of:

• How you've chosen to finance it (interest)
• How aggressively you minimise tax (tax)
• What depreciation schedule your accountant uses (depreciation)
• Non-cash write-offs like goodwill or intangibles (amortisation)

For an Australian SME, your reported EBITDA is typically your net profit after tax, with interest, tax, depreciation, and amortisation added back. That number—if cleanly prepared—gives a rough sense of operating performance.

But buyers don't stop there. Because your EBITDA includes dozens of line items that won't exist under their ownership, or that distort the true maintainable earnings of the business.

Why buyers adjust your EBITDA

A buyer isn't buying your historical financials. They're buying future cash flow. Specifically, they're buying the earnings the business will generate after you leave, run by a professional manager (or integrated into their existing operations), with all the noise removed.

When a buyer talks about "normalising" or "recasting" your EBITDA, they're trying to answer a simple question: What would this business earn in steady state, in my hands, without the current owner's fingerprints all over it? For a detailed look at how buyers approach this recasting process and why their number often comes in lower than sellers expect, we've written a companion guide that walks through the buyer's perspective step by step.

The process of getting to that number is called an EBITDA adjustment schedule. It's a line-by-line reconstruction of your P&L to reflect maintainable, recurring earnings. Some adjustments increase your EBITDA. Others decrease it. All of them matter.

What gets added back to EBITDA

These are expenses that appeared on your P&L but won't recur under new ownership, or that don't reflect the true operating performance of the business.

Owner's salary above market rate

If you pay yourself $300,000 but a professional manager would do the same role for $140,000, the buyer adds back $160,000. This is one of the largest and most common adjustments for Australian owner-operated businesses.

The test is simple: what would you have to pay someone external, with equivalent skills, to perform the owner's function? If you're working in the business full-time as a general manager, that's a GM salary (typically $120k–$180k depending on revenue and complexity). If you're part-time strategic only, the replacement cost might be lower, or zero.

Discretionary and personal expenses

Vehicles, mobile phones, travel with a personal component, home office costs, subscriptions, memberships, meals and entertainment—all common in Australian SMEs. If it's in the P&L but wouldn't be incurred by a buyer, it gets added back.

Buyers will typically request several years of detailed expenses and ask you to justify each category. A $15,000 "motor vehicle" line item that's actually your family SUV? Added back. A $6,000 "conference" expense in Bali? Added back.

One-off, non-recurring expenses

Legal disputes that have been resolved. Redundancy payments. An office relocation. A flood repair not covered by insurance. Any genuinely one-time cost that distorts your ongoing earnings gets normalised out.

The key word is genuinely. If you've had a "one-off" legal expense every year for three years, a buyer won't treat that as non-recurring. Pattern matters.

Non-cash charges

Depreciation and amortisation are already excluded in the EBITDA calculation. But other non-cash items—like share-based payments, asset write-downs, or provisions that were expensed but not paid—can also be added back, depending on the circumstance.

Related-party transactions above market

If you rent your business premises from a family trust at $80,000 per year, but market rent for an equivalent space is $50,000, the buyer adds back $30,000. The same logic applies to any above-market payments to related parties—spouse salaries, consulting fees to family members, inflated supplier payments to entities you control.

Buyers will benchmark every related-party cost. If you can't justify it at arm's length, it gets adjusted.

What gets stripped out of EBITDA

Not all adjustments increase the number. Some reduce it, because they reflect income or savings that won't continue post-sale.

Below-market owner salary

If you pay yourself $60,000 but the role requires a $130,000 manager, the buyer will deduct $70,000 from adjusted EBITDA. This is less common in Australian SMEs (most owners pay themselves well), but it happens, especially in businesses where the owner has deferred salary to reinvest in growth.

Below-market related-party transactions

Renting premises from yourself at half market rate? The buyer will adjust EBITDA down to reflect true market rent. Buying supplies from a related entity at a discount? Same treatment.

The principle is symmetry. If above-market costs get added back, below-market costs get deducted.

Government subsidies or grants that won't continue

JobKeeper, R&D tax incentives, state government grants—if the income is non-recurring or specific to your ownership, it gets stripped out. A buyer won't pay a multiple on income they can't replicate.

Extraordinary or windfall income

A one-time project that generated $200,000 in gross profit but won't repeat. A legal settlement in your favour. Insurance proceeds. Any revenue or profit line item that isn't part of normal trading gets removed from maintainable EBITDA.

A worked example: from reported profit to adjusted EBITDA

Here's how the adjustments play out in practice. Let's say you run a professional services business in Melbourne with the following P&L for the most recent financial year:

Item	Amount
Revenue	$2,400,000
Cost of goods sold / direct costs	($900,000)
Gross profit	$1,500,000
Operating expenses	($1,050,000)
EBITDA (reported)	$450,000
Depreciation & amortisation	($30,000)
Interest	($12,000)
Tax	($122,400)
Net profit after tax	$285,600

Your accountant-prepared financials show an EBITDA of $450,000. But when a buyer digs into the detail, they identify the following within your operating expenses:

Adjustment	Amount	Explanation
Owner salary	$260,000	Market replacement: $130,000 → add back $130,000
Motor vehicle (owner SUV)	$22,000	Personal use → add back $22,000
Travel & accommodation	$18,000	Discretionary personal component → add back $10,000
Professional development (owner MBA)	$14,000	Non-recurring, personal → add back $14,000
Legal fees (resolved dispute)	$25,000	One-off → add back $25,000
Rent (related party, below market)	$40,000	Market rent $65,000 → deduct $25,000

Your adjusted EBITDA calculation:

Item	Amount
Reported EBITDA	$450,000
Add: excess owner salary	+$130,000
Add: motor vehicle (personal)	+$22,000
Add: discretionary travel	+$10,000
Add: non-recurring professional development	+$14,000
Add: one-off legal fees	+$25,000
Less: rent normalisation to market	−$25,000
Adjusted EBITDA	$626,000

Your adjusted EBITDA is now $626,000—39% higher than the reported figure. If the buyer is offering a 3.5× multiple, that's the difference between a $1.575M valuation and a $2.19M valuation. A $615,000 swing.

Why defensibility matters more than magnitude

A large adjusted EBITDA number is worthless if you can't defend the adjustments. Buyers—especially sophisticated ones—will challenge every line item. They'll ask for invoices, timesheets, comparables, and written justifications.

The adjustments that hold up under scrutiny are those that are:

• Documented – You can produce evidence (invoices, contracts, market data) to support the claim.
• Consistent – The same logic applies across all years. You can't add back a $30k expense in year three if it also appeared in years one and two and you didn't flag it.
• Reasonable – The adjustment reflects genuine commercial reality, not wishful thinking. Claiming your $280k owner salary should be replaced with a $60k part-timer won't fly if you're working 50 hours a week in operations.
• Arm's length – Related-party transactions are benchmarked to market. If you can't show comparable third-party pricing, the buyer won't accept the adjustment.

In practice, the negotiation over adjusted EBITDA is often more important than the negotiation over the multiple itself. A 0.5× difference in multiple on a $500k adjusted EBITDA is $250k. But if the buyer successfully argues your adjusted EBITDA should be $400k instead of $500k, that same 0.5× gap becomes a $50k difference at a 3× multiple—and you've also lost $300k on the base valuation.

Common mistakes sellers make with EBITDA adjustments

Having reviewed hundreds of Australian business sales, these are the patterns that consistently hurt sellers:

Not preparing the adjustment schedule in advance

Most sellers wait until a buyer raises questions in due diligence. By then, you're reactive, defensive, and the buyer controls the narrative. Prepare your own normalised EBITDA—with full justifications—before you go to market. It becomes the anchor for negotiations.

Over-adjusting based on optimism

Adding back every conceivable expense in the hope a buyer will accept it rarely works. Aggressive add-backs that don't pass the pub test damage your credibility and make buyers suspicious of the legitimate adjustments. Be conservative, be honest, and focus on the items you can prove.

Not cleaning up the P&L before sale

If you know certain expenses are discretionary or personal, why are they still running through the business in your final year of ownership? Cleaning your financials 12–18 months before sale eliminates the need for complex adjustments and gives buyers a cleaner story.

Ignoring the buyer's adjustments

Buyers will propose their own version of adjusted EBITDA, often materially lower than yours. If you haven't done the work yourself, you have no basis to push back. This is where deals fall apart—not because of disagreement on price, but because the seller and buyer are calculating value off two completely different earnings bases.

How to make your adjustments bulletproof

If you want your adjusted EBITDA to survive due diligence and negotiation, here's what you do:

1. Prepare a detailed normalisation schedule. Build a line-by-line breakdown of every adjustment, with supporting evidence. Include: description of the expense, why it's being adjusted, quantum of the adjustment, and how you calculated it. For related-party transactions, include market comparables (e.g., three comparable office lease listings for rent benchmarking).

2. Get your accountant to review it. An independent, external accountant who reviews and validates your adjustment schedule adds credibility. Buyers trust third-party verification far more than an owner's spreadsheet.

3. Apply the same adjustments consistently across all years. If you're presenting three years of financials, the normalisation logic should be identical in each period. Inconsistencies are red flags.

4. Be prepared to walk through it live. In meetings with buyers, you'll be asked to explain your adjustments in detail. If you can't clearly articulate why a $35,000 add-back is legitimate, you'll lose it. Practise the explanation. Make it simple, factual, unemotional.

5. Benchmark your owner salary replacement cost. This is usually the largest adjustment. Don't guess. Look at actual salary data for equivalent roles in your industry and geography. SEEK, Hays Salary Guide, and industry associations publish this data. Use it.

What adjusted EBITDA means for your sale price

Once buyer and seller agree on adjusted EBITDA, that becomes the base for valuation. The multiple applied to that number depends on the quality of the business—revenue mix, customer concentration, management team, growth trajectory, and a dozen other factors.

But here's the critical insight: improving your adjusted EBITDA by $100k is often easier than improving your multiple by 0.5×.

You improve adjusted EBITDA by cleaning up discretionary spend, replacing yourself with a salaried manager, and running the business more professionally in the 12–18 months before sale. You improve your multiple by reducing owner dependency, shifting revenue to recurring models, diversifying customers, and building systems.

Both matter. But adjusted EBITDA is the foundation. If you get that number wrong, the rest of the negotiation is built on sand.

The bottom line

Adjusted EBITDA is not a technicality. It's the number your sale price is calculated from. The difference between a well-prepared, defensible adjusted EBITDA and a rough guess can easily be 20–40% of your valuation.

Most business owners discover this halfway through due diligence, when a buyer's accountant produces a normalisation schedule that bears no resemblance to what the owner was expecting. By then, you've lost negotiating leverage, time, and often the deal itself.

The fix is simple: do the work yourself, early. Build your own adjusted EBITDA model, validate it with your accountant, and use it as the foundation of your sale preparation. When you go to market with a clean, defensible number, buyers take you seriously. When you don't, they assume there's more buried in the detail—and they price that risk into their offers.
