How to Value a Services Business: The Core Formula

Determining the value of your professional services firm often feels more like art than science. Without physical assets or recurring software revenue, the worth of your agency or consultancy is tied directly to its profitability and future potential. For founder-led businesses in the $1 million to $10 million revenue range, the most common language spoken in acquisitions is the EBITDA multiple. Yet, arriving at a defensible number requires more than pulling a figure from your accounting software. The process of how to value a services business using EBITDA demands a clear-eyed look at your real profitability and a solid understanding of where you fit in the market. This guide provides a practical framework for calculating your firm’s value, focusing on the metrics that matter to potential buyers in both the UK and US. See our valuation basics hub for plain-English primers.

At its heart, the valuation for a professional services firm is straightforward. The core formula is:

Valuation = Normalized EBITDA x Market Multiple

EBITDA, or Earnings Before Interest, Taxes, Depreciation, and Amortization, serves as a proxy for your company's operating cash flow and profitability. This formula is the standard starting point for almost any discussion about agency valuation methods or selling a consulting firm. It allows buyers to compare companies on a level playing field, regardless of their financing structures or tax strategies.

However, this simple equation immediately presents two significant challenges for founders managing their own finances on QuickBooks or Xero.

  1. Your 'Profit' is not 'Normalized EBITDA'. The bottom line on your Profit and Loss (P&L) statement is often skewed by founder-specific decisions, one-off costs, and other items that a new owner would not incur. You must adjust for these to find the true, ongoing profitability.
  2. 'Market Multiple' is not a public number. Finding a credible multiple for a private company is difficult. The multiples for public companies are not directly applicable, creating a major hurdle in defending your professional services firm worth during negotiations.

Solving these two problems is the key to creating an accurate business appraisal for agencies and achieving a successful outcome.

Step 1: Calculating Business Value in Professional Services with Normalized EBITDA

Normalizing your EBITDA is the process of adjusting your reported profit to reflect the business's true earning power under a new owner. The goal is to present a clean picture of sustainable cash flow, answering the question: what profit would the business generate under normal operating conditions? For founders, this is one of the most common areas of confusion and contention during a sale process.

The reality for most bootstrapped startups is pragmatic. Founders often pay themselves in ways that mix salary, dividends, and personal expenses run through the business. These need to be untangled to reveal the underlying health of the company. The most common adjustments include:

  • Founder and Owner Compensation: Adjust any owner salaries to a fair market rate for a CEO or General Manager who would be hired to run a business of your size. If you pay yourself a low salary to conserve cash or a high one to extract profits, this needs to be corrected to what a non-owner executive would earn.
  • One-Off Expenses: These are costs that are not expected to recur and are not part of regular operations. Examples include a significant legal dispute, a one-time rebranding project, office moving costs, severance paid to a departing executive, or a large bad debt from a client that went bankrupt. These should be added back to your profit.
  • Discretionary Spending: Identify and add back expenses that are not essential to business operations. This could include lavish client entertainment, personal travel booked through the company, or salaries for family members who do not hold a legitimate role in the business.

An Example of Normalizing EBITDA

Here is a simple walkthrough of how to calculate Normalized EBITDA from a sample P&L. This conversion is crucial for determining your professional services firm worth.

  1. Start with Reported Profit. Pull the Net Income from your P&L in QuickBooks or Xero. Let's say it is $300,000.
  2. Calculate Standard EBITDA. Add back Interest, Taxes, Depreciation, and Amortization. If these total $50,000, your Reported EBITDA is $350,000.
  3. Adjust Founder Salary. The founder was paid $250,000, but the fair market rate for a General Manager is $150,000. Add back the $100,000 excess salary.
  4. Adjust One-Time Costs. The company paid $50,000 in legal fees for a client dispute that has been settled and will not recur. Add this back.
  5. Determine Normalized EBITDA. The final calculation is $350,000 (Reported EBITDA) + $100,000 (Salary Adjustment) + $50,000 (Legal Fees) = $500,000. This is the "real" profit figure a buyer will use for valuation.

This normalized figure is the foundation for calculating business value in professional services. Be prepared to defend every adjustment with clear documentation during a buyer's due diligence process.

Step 2: Finding a Defensible Market Multiple

Once you have a credible Normalized EBITDA, the next step in how to value a services business is finding a defensible market multiple. This is where many founders struggle because private market data is opaque. You cannot simply look up the multiple for a public company like Accenture and apply it to your business. Private deal data is noisier and less consistent.

Public companies trade at a premium due to their scale, liquidity, brand recognition, and the transparency required by public markets. A common rule of thumb is to apply a discount for applying public company multiples to private companies of 30-50%. So, if a comparable public firm trades at 10.0x EBITDA, a private equivalent might be valued between 5.0x and 7.0x.

For private professional services firms with revenues between $1 million and $10 million, the typical EBITDA multiple range is 4.0x to 7.0x. Where your business falls in that range depends entirely on its operational strength and risk profile. To find more specific data, you have a few options:

  • Paid M&A Databases: Services like PitchBook, Grata, and MergerMarket are the gold standard for transaction data. Access is expensive, but M&A advisors and investment bankers use these to find comparable "precedent transactions" for businesses of your size and type.
  • Business Brokers and M&A Advisors: Specialists who focus on your industry, such as digital marketing or IT consulting, have a pulse on the market. They can provide anecdotal but relevant data from recent deals they have seen or been involved in.
  • Public Data (with caution): You can use public sources like Yahoo Finance or BamSEC to analyze firms like WPP or other publicly traded services businesses. However, you must apply the private company discount and be mindful of vast differences in scale, geographic reach, and service lines.

A scenario we repeatedly see is founders relying on hearsay from peers or outdated articles. To build a stronger case, referencing a public M&A report can be powerful. For instance, an industry report might state that digital marketing agencies in the UK focused on performance marketing have been trading in a 5.0x to 6.5x EBITDA range. You should also track the broader market. See our commentary on the current multiple range for how economic cycles shift valuations.

Step 3: Justifying a Higher Multiple with Operational Strength

Getting a valuation at the high end of the 4.0x to 7.0x range is not about financial engineering. It's about demonstrating a low-risk, high-quality operation. An acquirer is buying your future cash flows, so anything that makes those cash flows more predictable and less dependent on you will increase your multiple. This is how you link service business financial metrics to your valuation story.

Here are the key operational levers that justify a higher multiple:

Client Concentration

High dependency on a few clients is a major risk for any acquirer. A key benchmark for low client concentration is ensuring no single client is more than 15% of your revenue. A diversified client base signals stability and reduces the impact of any single client churning post-acquisition.

Revenue Quality and Contract Type

Long-term retainers and recurring revenue contracts are far more valuable than one-off, project-based work. They provide predictable cash flow and demonstrate sticky client relationships. A business with 80% of its revenue from retainers will command a higher multiple than one with only 20%.

Team Structure and Founder Dependency

If the business cannot function without the founder's direct involvement in sales or key client delivery, its value is capped. This "key person risk" is a major concern for buyers. A strong second-tier management team that can run daily operations is critical for justifying a premium valuation.

Billable Utilization

Efficient staff deployment is a core indicator of a well-run services firm. A benchmark for healthy billable utilization is 80-85%. This metric shows that your primary asset, your people's time, is being used profitably. Rates much lower suggest inefficiency, while rates much higher may signal burnout risk.

Service Differentiation and Intellectual Property

What makes your firm unique? Do you have proprietary technology, a protected methodology, or a powerful brand in a specific niche? Differentiated services with higher margins are less likely to be commoditized and therefore carry a higher value. This could be a unique software tool you use for delivery or a trademarked strategic framework.

Profitability and Scalability

A business with higher profit margins is inherently more valuable. A firm with a 25% normalized EBITDA margin is a more attractive asset than one with a 10% margin, even at the same revenue. Scalability, or the ability to grow revenue without a perfectly linear increase in headcount and costs, also attracts a premium multiple.

Practical Takeaways for Founders

Knowing how to value a services business using EBITDA is a critical skill for any founder considering an exit, fundraising, or bringing on a partner. The process is less about complex financial models and more about building a credible, evidence-based story about your firm's profitability and stability.

  1. Normalize Your EBITDA Regularly. Move beyond the P&L in your QuickBooks or Xero account. Start tracking adjustments on a quarterly or annual basis. This includes assigning a fair market salary for your role and isolating any one-off expenses as they occur.
  2. Gather Market Intelligence. While you may not subscribe to expensive databases, you can follow industry reports and talk to advisors to get a sense of the current multiple range for a business like yours in the UK or US market. This prepares you for realistic negotiations.
  3. Focus on De-Risking Your Operations. The path to a premium valuation lies in proving your firm's future cash flows are secure. Turn your attention to improving key metrics like client concentration and billable utilization, strengthening your management team, and locking in recurring revenue. These are the factors that prove your firm's profitability is sustainable long after you are gone.

By focusing on these areas, you can build a more valuable company and enter any valuation discussion with clarity and confidence. For a broader overview of related topics, see our valuation basics hub.

Frequently Asked Questions

Q: What is the difference between EBITDA and Seller's Discretionary Earnings (SDE)?
A: SDE is often used for smaller businesses (typically under $1 million in profit). It is calculated by adding the owner's salary and benefits back to EBITDA. EBITDA is the standard for larger firms where a buyer assumes they will hire a professional manager to replace the founder, making the founder's specific compensation an adjustment.

Q: How do economic conditions affect professional services firm worth?
A: In downturns, multiples often compress as buyers become more risk-averse and financing becomes more expensive. However, firms with high recurring revenue, strong client relationships, and non-discretionary services tend to hold their value better than those reliant on short-term project work.

Q: Should I use a revenue multiple instead of an EBITDA multiple for my agency?
A: While revenue multiples are common for high-growth, unprofitable tech companies, EBITDA multiples are the standard for profitable professional services firms. Acquirers are buying sustainable cash flow, making profitability the most important metric in agency valuation methods.

Q: Do I need a formal valuation from an expert to sell my business?
A: While not mandatory, a professional valuation or a third-party Quality of Earnings (QoE) report can significantly strengthen your negotiating position. It provides a defensible, independent analysis of your normalized EBITDA and prepares you for the scrutiny of buyer due diligence, preventing surprises later.
