Many owners struggle here because valuation isn't one formula. It's a set of methods that depend on your industry, your financials, and why you're valuing the business in the first place. GF Data's Q3 2025 report found average purchase-price multiples on middle-market deals hit 7.5x adjusted EBITDA, up from 6.9x the prior quarter, proof that multiples move and context matters.
There is a further complication. All six of the methods below produce an estimate of what a business is worth. An institutional buyer runs a different calculation entirely: not "what is this company worth today" but "what return can this company generate for us". This guide walks the six methods with worked examples, then shows you the seventh calculation, the one that actually sets your price.
Key Takeaways
- Six common methods: book value, times revenue, earnings multiplier, DCF, market comps, and EBITDA multiples
- No single method is definitive; professionals typically triangulate 2-3 approaches
- Every one of them produces an estimate. The buyer runs a returns test instead
- Institutional investors typically underwrite to a target IRR of 20% to 30%, and that hurdle is what sets the price they can pay
What Is Business Valuation and Why It Matters
Business valuation is the process of estimating a company's fair economic value using financial, operational, and market data. The National Association of Certified Valuators and Analysts (NACVA) describes it as determining that fair value. In practice, the method you use depends on why you need the number.
Common reasons owners seek a valuation:
- Selling the business or entertaining an acquisition offer
- Raising capital or bringing in investors
- Partner or shareholder buyouts
- Tax and estate planning
- Litigation or divorce proceedings
- Succession planning between generations or to management
For middle-market owners of companies generating $10 million to $100 million in revenue, the right number depends heavily on who's buying. A private equity firm weighs cash flow and scalability. A strategic acquirer pays for synergies. A family office often prioritizes long-term stability.
Napkin Math vs. Institutional Math
A quick calculation using a revenue multiple gives you a directional sense of value. It won't hold up in due diligence, with a lender, or across the table from a sophisticated buyer.
The gap is not really about rigour. It is about which question is answered. Napkin math and formal valuation both look backwards at what the business has produced. An institutional buyer looks forward at what it can extract, and prices the company against its own cost of capital. The two can land a long way apart on the same financials.
6 Methods to Value a Business (With Examples)
Method 1: Book Value
Book value is the simplest calculation: total assets minus total liabilities.
Example: A company has $4.2 million in total assets and $1.8 million in total liabilities.
Book Value = $4.2M - $1.8M = $2.4 million
This method is easy to calculate, but it usually understates true value. It ignores intangible assets (brand reputation, customer relationships, proprietary processes) that often drive the majority of a company's actual worth. Use it as an asset floor, not a sale price.
Method 2: Times Revenue (Revenue Multiple)
This method multiplies annual revenue by an industry-specific multiplier.
Example: A software company generates $5 million in annual revenue. Applying a 2.5x industry multiple:
$5M x 2.5 = $12.5 million
Revenue multiples are most common for early-stage or high-growth companies that haven't yet reached consistent profitability. The catch: revenue multiples neglect profitability entirely. A business with strong revenue but thin margins can look deceptively valuable using this method alone.
Method 3: Earnings Multiplier (P/E-Based)
Rather than revenue, this method applies a multiple to net earnings, a more accurate indicator of what a business actually generates.
Example: A company with $800,000 in annual net earnings, using a 4x earnings multiple:
$800,000 x 4 = $3.2 million
Earnings-based methods are generally preferred over revenue multiples for established, profitable businesses because they reflect actual bottom-line performance, not just top-line size. Valuation literature describes P/E as the most commonly used equity multiple, though it measures equity value, not enterprise value.
Method 4: Discounted Cash Flow (DCF)
DCF projects future cash flows and discounts them back to present value using a chosen discount rate. Kroll calls it the most recognized income-approach method in business valuation.
Simplified example:
| Year | Projected Cash Flow | Present Value Factor | Present Value |
|---|---|---|---|
| 1 | $500,000 | 0.91 | $455,000 |
| 2 | $550,000 | 0.83 | $456,500 |
| 3 | $600,000 | 0.75 | $450,000 |
Sum of present values is approximately $1.36 million (before terminal value)
DCF is often treated as the most rigorous method because it ties value to expected future performance rather than a snapshot multiple. Its accuracy hinges entirely on your growth and discount rate assumptions, and small changes in either can swing the result substantially.
Method 5: Market Capitalization / Comparable Company Analysis
For public companies, market cap is simple: share price x shares outstanding. It's a real-time, market-derived value.
Private middle-market companies don't have a share price, so the analogous approach is comparing to recent sale prices of similar businesses, known as precedent transaction analysis. This method pulls from actual M&A deals to estimate what a comparable business would fetch today.
One limitation to flag: market cap ignores debt. Two companies with identical equity value can carry very different debt loads, which is why enterprise value (equity value plus debt less cash) or private-market comps typically give a fuller picture for deal purposes.
Method 6: EBITDA Multiple
EBITDA (earnings before interest, taxes, depreciation, and amortization) is the standard metric for middle-market deal valuation because it strips out financing and accounting decisions to show core operating performance.
Typical multiple ranges vary by data provider and deal size. GF Data reported an average of 7.5x TTM adjusted EBITDA in Q3 2025 across $10M-$500M transactions, while BVR's DealStats reported a lower median of 3.5x for the same period. That gap is a reminder that "average purchase price" and "median selling price" aren't the same measurement.
Factors that push a company up or down within its industry's range:
- Recurring or contracted revenue vs. one-off sales
- Customer concentration and diversification
- Founder dependency and management depth
- Goodwill and brand strength
Worked example: A specialty manufacturer generates $4 million in EBITDA. At a 6x multiple:
$4M x 6 = $24 million enterprise value
Exit Boston has seen this play out directly. In one label manufacturing engagement, EBITDA grew from $3.4 million to $9.0 million, and the multiple expanded from 6.4x to 8.2x as the business became less founder-dependent and more institutionally ready. The multiple itself, not just the earnings, can move with the right positioning.
What You Need Before Valuing a Business
Clean financials are the foundation buyers and lenders will scrutinize.
Core financial documents:
- 3+ years of profit and loss statements
- Balance sheets
- Cash flow statements
- Tax returns
Supporting materials:
- Customer retention and concentration metrics
- Outstanding liabilities and debt schedules
- Intellectual property documentation
- Inventory and asset lists
Disorganized financials slow a valuation and erode buyer confidence in diligence, which often leads to lower offers or renegotiated terms after an initial agreement.
The Seventh Calculation: The Returns Test a Buyer Runs
None of the six methods above is the one that decides your price. An institutional buyer starts from the other end. Its question, put plainly in Exit Boston's own transaction material, is: if we buy this company today, grow it, use some debt, and sell it in five years, what return do we earn?
That reframes everything. The buyer is not weighing your history against a formula. It weighs five things at once: current earnings, growth potential, risk, capital requirements, and expected investor returns. The price is whatever satisfies the last one.
The hurdle is a real number. Institutional investors typically target internal rates of return between 20% and 30%, depending on the risk and size of the investment. Every dollar of price has to still clear that hurdle at exit. If the growth case is thin or the risk is high, the only variable left to move is what the buyer pays today.
Debt does part of the work. In middle-market transactions, senior bank debt typically runs 2.0x to 3.0x EBITDA. On the $4 million of EBITDA in the worked example above, that is roughly $8 million to $12 million of the $24 million price funded by a lender rather than by the buyer's equity. A business a lender will not support at that level has to be funded with more equity, and more equity means a lower price for the same return.
Returns come from three places, not one. The drivers are EBITDA growth, debt reduction as cash flow repays the loan, and multiple expansion, meaning the business is better quality at exit than at entry. A seller who can only point to the first of the three is asking a buyer to underwrite a narrower case.
Six characteristics move the multiple inside any buyer's range: growth potential, recurring revenue, management strength, market size, scalability, and the quality of financial reporting. A strategic acquirer will still pay a premium for synergies a financial buyer would not price, but it applies the same six tests first.
Founder dependency remains the biggest single drag, because the buyer is not acquiring the owner. It is acquiring what remains after the owner leaves.
Why Professional Guidance Matters for Middle-Market Valuations
A DIY valuation formula gives you a starting point. It rarely reflects what a qualified buyer would actually pay in a competitive process.
Exit Boston combines financial analysis with buyer-specific positioning and industry research, helping founders see the gap between a formula's output and real market appetite. That distinction shows up in actual deal outcomes:
- Independent beer importer: expected $18.0M-$20.0M, closed at $24.0 million all-cash
- Electrical contractor: expected $14.0M-$16.5M, closed at $18.81 million
- Municipal water drilling company: expected $10.0M-$11.5M, closed at $12.9 million
The stronger process does not lock onto a single valuation number. It identifies qualified buyers whose acquisition criteria fit the business, then creates competitive tension among them, which is often what pushes the final price above the formula-based estimate.
Frequently Asked Questions
How much is a business worth with $1 million in sales?
Revenue alone isn't enough. Value depends on profitability, growth, risk, and what a lender will fund. Using a rough 1x-2x revenue multiple, a $1M-revenue business might land in the $1M-$2M range, but profitable niches command far more.
Can you look up the value of a business?
Public company values are visible instantly via market capitalization. Private business values require applying valuation methods yourself or hiring a professional appraiser; there's no public lookup tool, and none would capture buyer fit.
What are five things to consider when evaluating a business?
Profitability and earnings trends, assets and liabilities, market position and competition, growth potential, and customer or revenue concentration. Add a sixth if you can: whether the business runs without its owner.
What does "business worth" mean?
"Business worth" refers to the estimated fair market value a buyer would reasonably pay, which can differ significantly from book value or what the owner personally believes the business is worth.
What are the top 3 business valuation methods?
DCF, EBITDA multiples, and comparable transaction analysis are the three most relied upon for private company sales. In practice the middle market runs on the second one, tested against a buyer's return hurdle.
When should I get a professional business valuation?
Get one before selling, raising capital, or navigating a partner dispute. A professional valuation holds up far better under buyer or lender scrutiny than a self-calculated estimate, and it shows you which drivers are capping your multiple.
