If you are preparing to sell your business, you will encounter the term EBITDA early and often. It will appear in every information memorandum, every heads of terms, and every valuation conversation you have. Understanding it — and understanding how buyers use it — is not optional.
What EBITDA actually measures
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortisation. It is a measure of a business’s operating profitability — the cash the business generates from its core operations, before the effects of financing decisions, accounting conventions, and tax arrangements.
The reason buyers use EBITDA rather than net profit is precisely because it strips those things out. Two businesses with identical underlying operations can show very different net profits depending on how they are financed, how aggressively they depreciate assets, and how their tax affairs are structured. EBITDA provides a more comparable, more transferable view of earning power.
For private business acquisitions, EBITDA is almost always the foundation of a valuation. A buyer who is considering paying 5× EBITDA is saying: I will pay five years’ worth of the business’s operating profit for the right to own it going forward.
How multiples work
The multiple applied to your EBITDA is not arbitrary. It reflects a buyer’s assessment of the risk and quality of those earnings.
A multiple of 3× means: this business is risky enough, uncertain enough, or owner-dependent enough that I only expect to recover my investment over three years of undisturbed trading. A multiple of 8× means: this business is predictable enough, systemised enough, and well-managed enough that I am comfortable paying eight years’ worth of earnings upfront.
The spread between the floor and ceiling in your sector is typically 2 to 4 turns of EBITDA — meaning the structural and qualitative characteristics of your business can move your valuation by 50 to 100 percent or more, at the same level of underlying profit.
This is the central insight of exit preparation: the multiple is not fixed. It is built.
The adjustments that change your number
When buyers calculate EBITDA, they start from your reported profit and work through a series of adjustments. Your advisors will do the same. Understanding these adjustments gives you the ability to influence your number before the process starts.
Owner remuneration
If you are paying yourself above or below a market-rate salary for the role you perform in the business, the difference is typically adjusted. If you pay yourself £350,000 and a competent CEO replacement would cost £120,000, the £230,000 difference is added back — increasing the adjusted EBITDA buyers will value.
The reverse is also true. If you undercharge yourself to show a higher profit, buyers will adjust the other way.
Personal expenses run through the business
It is common for owner-managed businesses to run personal expenses — travel, hospitality, vehicle costs, and similar items — through the business. These are legitimate adjustments that increase EBITDA when added back, but they require clean documentation and a clear audit trail. Buyers’ accountants will scrutinise these carefully.
One-off costs
Significant non-recurring costs — a one-time restructuring, a legal dispute, a piece of capital expenditure with no ongoing equivalent — can typically be added back to EBITDA. These should be documented and defensible.
EBITDA in the context of growth
Buyers do not only look at the most recent year’s EBITDA. They look at a three-to-five year trend. A business showing consistent EBITDA growth commands a better multiple than one showing flat or volatile performance — even if the current-year number is identical.
This matters enormously for timing. If you are considering an exit in three years, the decisions you make in this financial year will appear in the track record that buyers evaluate.
The sectors and the numbers
EBITDA multiples vary significantly by sector. As a general orientation:
- Technology / SaaS businesses with high recurring revenue can trade at 6× to 12× or above
- Professional services — accountancy, marketing, consulting, legal — typically range from 4× to 8×
- Manufacturing and industrial businesses sit around 3× to 6×, depending on customer concentration and capital intensity
- Construction and trades tend to range from 2.5× to 5×
- Retail and consumer businesses vary widely: 2.5× to 6×
These ranges assume a reasonably well-prepared business. Owner dependency, revenue concentration, and weak documentation will compress any multiple toward the floor. A well-prepared business with strong fundamentals can trade above the ceiling.
What EBITDA doesn’t capture — and what buyers also look at
EBITDA is the foundation, but it is not the whole valuation. Sophisticated buyers layer several other assessments on top of it.
Revenue quality — how much of your income is recurring, contracted, or otherwise predictable — affects how they risk-adjust the multiple. A business with 80% recurring revenue is structurally different from one that re-earns its income every year.
Customer concentration — if a single client represents more than 20 to 25 percent of revenue, most buyers apply a risk discount. If one client represents 50%, the multiple will be materially compressed regardless of EBITDA.
Management team depth — a business that has a competent senior team capable of operating independently commands a higher multiple than one where the owner is the de facto CEO, CFO, and head of sales simultaneously.
Contracted backlog and pipeline — particularly in B2B service businesses, the visibility of future revenue matters. A strong order book provides confidence that EBITDA will persist post-acquisition.
How to improve your position before exit
The most actionable insight from understanding EBITDA is that your choices in the years before exit directly affect your eventual multiple.
Normalising your salary to market rate — documented clearly — increases adjusted EBITDA and reduces the risk that buyers will challenge the adjustment. Building a management team reduces owner dependency and supports a higher multiple. Shifting revenue toward recurring or contracted models improves revenue quality. Reducing customer concentration directly addresses one of the most common discount factors.
None of this requires a new product or a fundamental change to the business. It requires deliberate preparation — and time.
