Understanding the business valuation process
Business valuation is the process of determining what a business is worth — financially, commercially, and in the eyes of a prospective buyer. It considers your profits, assets, market conditions, and a range of other factors to arrive at a realistic asking price.
If you're thinking about selling, understanding how a valuation works — and what influences the number — will help you set the right expectations and prepare your business to achieve the best possible outcome.
Why a business valuation matters
Getting your valuation right at the outset matters more than most sellers realise. Ask for too much and you'll put buyers off before conversations even begin. Ask for too little and you miss cashing out on your full returns.
A credible, well-supported valuation also makes for a smoother sale. Buyers and their advisers will scrutinise the figures closely during due diligence. If your asking price is grounded in solid reasoning, there's less room for renegotiation later in the process.
What does a business valuation look at?
Valuers don't just look at a single number. They consider a combination of financial and commercial factors, including:
- Your profits — usually measured over the past three years
- Your assets — equipment, property, stock, and anything else of tangible value
- Your turnover and revenue trends
- The strength and transferability of your customer base
- How dependent the business is on you personally
- Sector conditions and comparable sales
- Outstanding liabilities, loans, or legal matters
- Two businesses in the same sector turning over the same revenue can have very different valuations depending on how profitable, scalable, and buyer-ready they are.
The main valuation methods
There is no single formula that applies to every business. In practice, valuers use different methods depending on the type of business, its financial profile, and the sector it operates in.
Profit-based valuation (EBITDA multiple)
This is the most widely used method for trading businesses and the one you are most likely to encounter. It takes your Earnings Before Interest, Tax, Depreciation and Amortisation (EBITDA) — a measure of your operating profit — and multiplies it by a figure that reflects your sector and circumstances.
For most SME business sales in the UK, that multiplier typically sits between two and five, though it can go higher for businesses with strong recurring revenue, a loyal customer base, or particularly favourable market conditions. A profitable, well-run business with minimal owner dependency will command a higher multiple than one that is heavily reliant on the founder.
Asset-based valuation
Asset-based valuations add up the value of everything the business owns — machinery, vehicles, property, stock, intellectual property — minus any liabilities. This method is most commonly used for asset-heavy businesses such as manufacturers, haulage companies, or businesses with significant property holdings.
The limitation of this method is that it can undervalue a business with a strong trading history and customer relationships, since goodwill — the intangible value that comes with an established business — isn't always easy to capture in an asset list.
Turnover multiple
In some sectors, particularly where profit margins are low or inconsistent, valuations are based on a multiple of annual turnover rather than profit. This approach is more common for businesses like care homes, accountancy practices, or subscription-based service businesses, where revenue is a reliable indicator of underlying value.
Market-based valuation (comparables)
A market-based valuation looks at what similar businesses have sold for and uses those figures as a benchmark. This is harder to apply to smaller businesses because comparable sales data isn’t always publicly available, but an experienced broker with a track record of selling in your sector will have a good sense of what the market is currently willing to pay.
Discounted cash flow
Discounted cash flow (DCF) projects your future cash flows and works backwards to establish what the business is worth in today’s money. It’s a method you may come across, but it’s rarely used as the primary approach for SME business sales. It requires reliable, consistent cash flow forecasts, and for most owner-managed businesses, that level of financial predictability is difficult to demonstrate convincingly. Where it does appear, it tends to be used alongside other methods rather than on its own.
| Method | Best suited to | Key limitation |
| Profit-based (EBITDA multiple) | Trading businesses with consistent profits | Can undervalue a business with strong goodwill |
| Asset-based | Asset-heavy or property-based businesses | Less reliable — ignores cost base |
| Market-based (comparables) | Any business where comparable sales data is available | Data may be limited to experienced brokers only |
| Discounted cash flow (DCF) | Businesses with consistent, predictable cash flow | Rarely used as a primary method for SME sales |
What increases or decreases business value?
Valuation isn't just a backward-looking exercise. Buyers are buying the future, not just the past, so factors that suggest a stable or growing business carry real weight.
Things that tend to increase value include consistent or growing profits, a diversified customer base (with no single customer accounting for a disproportionate share of revenue), strong recurring revenue, long-term contracts or leases, a capable management team that can operate without the owner, and well-maintained assets. A clean set of accounts and clear financial records also make a meaningful difference.
Things that can reduce value, or make a sale harder, include declining revenues, heavy reliance on the owner's personal relationships or skills, customer concentration risk, outstanding litigation or disputes, poorly maintained equipment, and inconsistent or incomplete financial records.
What a professional valuation involves
A formal business valuation isn’t just a figure pulled from thin air. It involves a thorough review of your financials — typically the last three years of accounts — alongside an assessment of your assets, liabilities, trading history, and market position.
Valuers will often adjust your profit figures to account for any one-off costs or owner-related expenses that a buyer wouldn’t inherit. This normalised profit figure is what the multiple is then applied to.
At Selling My Business, our in-house valuers carry out business valuations informed by over 60 years' experience and more than 10,000 completed business sales. That breadth of comparable data means the valuations we provide are grounded in what the market will actually pay, not just what looks good on a spreadsheet.
DIY valuation versus a professional valuation
Online valuation calculators provide a strong ballpark and can give you a rough ballpark, but they cannot account for the nuances of your specific business. They typically rely on broad sector averages, rather than local market conditions, the quality of your management team, or the strength of your customer relationships.
A professional valuation gives you a credible, defensible figure to take to market — one that buyers and their advisers will take seriously. It also gives you the opportunity to understand where your value lies and, if needed, what you could do to strengthen it before you go to market.
If you're not ready to sell immediately, an early valuation can be a useful planning tool. Knowing what your business is worth today helps you set a realistic timeline and identify what improvements would make the most difference to your eventual sale price.
