A business is not worth “6 times profit” because someone said so over coffee. A multiple can be useful, but only when the right number is used in the right way.
Too many SME owners grab the headline figure and stop there. That can push value far too high, or drag it far too low. Consult EFC helps business owners get a more defensible view of value for a sale, fundraising round, or planned exit, so decisions rest on evidence, not wishful thinking.
Let’s start with what a multiple is, and what it isn’t.
What a valuation multiple actually tells you
A valuation multiple is a shortcut. It takes a lot of judgement about growth, risk, margins and cash flow, then squeezes it into one number.
That makes it handy, but it also makes it dangerous. Think of it like price per square foot on a house. It’s useful for a first look, but it won’t tell you if the roof leaks, the boiler is tired, or the street is noisy.
In business valuation, a multiple usually links value to earnings or revenue. If a company has £1 million of EBITDA and the market supports 5x, that implies a £5 million enterprise value. Clean. Fast. Easy to repeat. Also easy to get wrong.
How earnings multiples are usually used in SME valuations
The earnings measure matters as much as the multiple itself. Different businesses need different lenses.
Here’s a quick guide:
| Metric | Usually used for | Main risk |
|---|---|---|
| EBITDA | SMEs with management depth and stable operations | It can mislead if earnings are not normalised |
| Revenue | Growth businesses or loss-making firms, often software | Margins, churn and cash burn can be ignored |
| SDE | Owner-managed businesses where the owner is central | It gets confused with net profit far too often |
EBITDA strips out financing, tax and some accounting noise. SDE, or Seller’s Discretionary Earnings, goes further and adds back owner salary and personal or discretionary spend. Revenue multiples are more common when profits are thin or deliberately suppressed, often in software.
The right metric depends on the business model and the likely buyer. A trade buyer looking at a mature engineering firm won’t think like an investor looking at a recurring-revenue SaaS business.
Why a single multiple never tells the full story
Two businesses can both be “worth 5x”, on paper, and still deserve very different values.
Take two agencies with the same EBITDA. One has recurring retainers, ten decent-sized clients, low staff churn and a second-tier management team. The other has one client making up 40 per cent of revenue, the founder signs every deal, and cash is tied up in slow debtors. Same multiple? Not in the real world.
A multiple hides a lot. It hides customer concentration. It hides working capital pressure. It hides whether the owner can disappear for two weeks without the place wobbling.
That’s why multiples are a starting point, not an answer.
The most common ways multiples mislead business owners
Most mistakes don’t come from the maths. They come from using the maths on the wrong base, the wrong peers, or the wrong story.
Using the wrong earnings figure
This is the classic error. Someone takes raw profit from the accounts, slaps on a market multiple, and calls it a valuation.
But raw profit is not the same as adjusted EBITDA, and adjusted EBITDA is not the same as SDE. One-off legal fees, exceptional repair bills, owner’s car costs, family payroll, and non-recurring stock write-downs can all distort the number.
If those items aren’t normalised first, the multiple magnifies the mistake. Overstate earnings by £100,000 and apply 5x, and you’ve just added £500,000 to value. Nothing magical happened in the business. The input was wrong.
For many owner-managed SMEs, this matters more than the headline multiple. The base earnings figure has to reflect maintainable earnings, not accounting noise.
Copying a headline multiple from the wrong kind of business
This happens all the time. A founder reads that software companies trade at 10x EBITDA, or sees a listed company on 14x, then assumes their own business should be somewhere nearby.
That leap is where valuations go off the rails.
Current UK market evidence puts many private SMEs in a much lower band, often around 3x to 7x EBITDA. Micro-businesses are often closer to 2x to 4x. Public companies can trade around 13x to 16x EBITDA, but they are larger, more liquid, more diversified and less dependent on one person.
Sector matters too, but only after size and quality. Some software businesses can attract 8x to 12x. Fine. But that usually comes with strong recurring revenue, low churn, decent margins and predictable growth. A smaller UK software firm with patchy renewals and thin reporting is not the same thing.
US benchmark data can be even more misleading. Different market, different buyers, different pricing.
Ignoring owner dependence and key-person risk
If the founder wins the sales, manages delivery, approves pricing and holds the client relationships, the business is harder to transfer. Buyers know this.
The same problem shows up when one salesperson brings in most of the work, or one technical specialist holds the keys to delivery. If that person leaves, value can leave with them.
A stable business with process, management depth and shared customer ownership usually earns a better multiple. A business that lives in one person’s head usually doesn’t.
This is not theory. It changes price. A buyer may like the business and still mark the multiple down because transition risk is too high.
Forgetting the bridge from enterprise value to equity value
This part catches owners out late in the deal, when expectations are already set.
A multiple usually gives you enterprise value. That is not the same as the equity value you take home. To get there, you need to adjust for debt, surplus cash, working capital and sometimes deferred spend.
A quick example helps. If a business has £1 million of EBITDA and supports 6x, the enterprise value is £6 million. Sounds great. But if there is £1.2 million of debt, a £300,000 working capital shortfall and only £200,000 of surplus cash, the equity value drops to £4.7 million before other deal points.
A strong multiple can still lead to a smaller cheque.
Deferred maintenance, overdue tech investment, aged stock, or underfunded working capital can all eat into value. So can HMRC liabilities or unpaid obligations that a buyer will spot in diligence.
How to spot when a multiple is being stretched too far
A valuation doesn’t need to be pessimistic. It does need to be believable.
Signs the valuation is too optimistic
Start with the peer group. If the comparable companies are vague, too big, US-based, or from a different part of the market, the multiple is on shaky ground.
Then look at growth. If the forecast assumes a sudden jump in margin, cleaner systems and lower churn, but none of that is visible today, the valuation is leaning on hope. Another warning sign is when growth is built into both the forecast earnings and the multiple. That is a double count.
Watch for reports that give one neat number with no range and no sensitivity analysis. Real valuations move when assumptions move. If a figure stays rigid regardless of risk, it usually means the work hasn’t been stress-tested.
Cash is the final sense-check. If the implied value is miles above what the business can support in maintainable cash flow, pause.
Questions that expose weak assumptions
A few simple questions can cut through a lot of fog:
- Why was this multiple chosen, and which real UK comparables support it?
- What was adjusted out of earnings, and would a buyer accept every add-back?
- Are we valuing EBITDA, SDE, or revenue, and does the multiple match that metric?
- What happens to value if growth slows, churn rises, or one major client leaves?
- Is this enterprise value or equity value after debt and working capital?
If clear answers don’t come back, the number probably isn’t ready to rely on.
What a more reliable business valuation should include
A better valuation does not worship one formula. It tests the answer from more than one angle.
Cross-checking multiples with DCF and asset-based methods
Multiples tell you how the market prices similar businesses. Discounted cash flow tells you what the business can support in actual future cash. Asset-based value tells you something else again, which matters more in asset-heavy firms or distressed situations.
When those methods point to roughly the same range, confidence improves. When one method shouts and the others whisper, that’s a sign to re-check the assumptions.
This is why proper valuation work triangulates. It doesn’t pretend one method can do every job.
Using UK-specific comparables and sensible ranges
Good comparables need to look like your business, not like the business you wish you had. Size, geography, margin profile, customer mix and buyer type all matter.
For UK SMEs, local evidence matters. Private-company data from the year ended Dec 2025 is more useful than an old US software multiple pulled from a blog. A sensible valuation also gives a range, not one heroic point estimate.
That matters for planning. If you are preparing for sale, a business valuation for exit gives you time to fix the issues that keep you at the bottom of the range.
Why independent judgement matters more than a quick formula
You can build a quick spreadsheet in an hour. You can’t build good judgement that quickly.
A defensible valuation needs clean adjustments, the right peer set, and a proper bridge from enterprise value to equity value. It also needs to fit the audience. The number you use for a buyer is not always the same as the number that will stand up with investors or HMRC.
For companies raising capital, valuation for business fundraising needs to reflect the investor context, not sale logic alone. Consult EFC gives SMEs a partner-led view of value that can be defended in front of buyers, investors, HMRC, or the board. That’s the difference between a rough estimate and a report people can rely on.
The number is never the whole story
A tidy multiple feels reassuring. It gives you something clean to hold onto. But a business valuation only works when the earnings are normalised, the comparables are real, and the economics underneath the number make sense.
Treat any multiple as a starting point. Test it, adjust it and pressure-check it against cash flow, risk and deal structure.
When the valuation is robust, better decisions follow. That helps whether you’re growing, raising money, or planning your exit.
