How owner-managed businesses are valued: normalised EBITDA and multiples explained

"What is my business worth?" is one of the first questions owners ask when they start thinking about a sale – and one of the hardest to answer with a single number. In practice, value is a range. Where a business sits in that range depends on its earnings, its risks and the buyers who are interested in it.

This article explains an approach commonly used for profitable owner-managed businesses, and the factors that move the result. Other methods apply in some circumstances (see "Other approaches" below).

Value is a range, not a figure

A valuation outside a live sale is an indicative view: a reasoned range based on the information available. The actual price is set in a sale, by what a buyer is prepared to pay and on what terms.

Understanding how the range is built is still valuable. It tells you what buyers will focus on, and what you could do to improve the outcome.

Step 1: Work out sustainable earnings

Many profitable owner-managed businesses are valued by reference to their sustainable earnings, often expressed as normalised EBITDA – earnings before interest, tax, depreciation and amortisation, adjusted to show what a new owner could expect.

The adjustments matter because owner-managed accounts reflect the owner's own choices. Common normalisation adjustments include:

• Owner remuneration – replacing the owner's actual salary and dividends with the market cost of someone doing their role.
• One-off income or costs – an exceptional contract, a legal dispute, a one-off restructuring.
• Related-party arrangements – rent paid to the owner for property they own, at more or less than a market rate; family members on the payroll.
• Personal costs run through the business.
• Discontinued activities that will not form part of the business going forward.

The result should be a figure a buyer can recognise and test. Adjustments without evidence tend to be challenged in due diligence.

Step 2: Understand what drives the multiple

Sustainable earnings are then considered against a multiple. An EBITDA multiple expresses the business's enterprise value – its value before debt and cash are taken into account – relative to its sustainable earnings. The multiple reflects risk, growth, scale, the quality of earnings and the level of buyer demand. There is no single multiple for a sector or size of business: it reflects how buyers see this business.

Factors that typically support a stronger valuation:

• Recurring or contracted revenue, rather than one-off projects.
• A broad customer base, rather than reliance on a few customers.
• Low dependence on the owner – a team and processes that will continue after the sale.
• Consistent, well-evidenced financial information, including reliable monthly management accounts.
• Growth that is credible and supported by past performance.
• Scale – larger businesses often attract a wider pool of buyers.

Factors that typically weigh on value include customer concentration, declining or volatile trading, key-person risk, weak records and unresolved issues such as disputes or overdue liabilities.

Published "rules of thumb" for a sector can be a starting point for discussion, but they rarely reflect the specific strengths and risks of an individual business.

Step 3: From headline value to what you receive

The figure produced by earnings × multiple is usually an enterprise value – the value of the business before its debt and cash are considered. Several things sit between that figure and the amount an owner actually receives:

• Net debt or surplus cash – borrowings and debt-like items are typically deducted; surplus cash may be added.
• Working capital – deals often assume a normal level of working capital is left in the business.
• Deal structure – part of the price may be deferred or linked to future performance, which affects both timing and certainty.
• Costs and tax – adviser fees and the tax position on the sale. Your tax adviser can explain how this applies to you.

This is why two offers with similar headline values can be worth quite different amounts to a seller.

Other approaches

Some businesses are valued differently:

• Asset-based approaches may suit businesses whose value lies mainly in property or other assets, or that are not consistently profitable.
• Discounted cash flow looks at forecast future cash flows. It is used more for larger businesses with reliable forecasts.

For many profitable owner-managed businesses, sustainable earnings and the factors above remain the centre of the discussion.

Why buyers and sellers see value differently

Sellers naturally see the potential in their business. Buyers price in risk – and they are paying for future earnings under their ownership, not past effort. A valuation that explains the reasoning, and identifies which risks a buyer will focus on, helps both sides reach a realistic view sooner.

Improving value before a sale

Many of the factors that move value can be improved, but rarely overnight. Owners often benefit from starting preparation 12–36 months before a planned sale: improving the quality of financial information, reducing reliance on the owner and key customers, and resolving issues before a buyer finds them.
