How to Determine Your Company's Valuation
Business valuation methods range from EBITDA multiples to discounted cash flow. Which one applies depends on your industry, size, and buyer type.
Understanding how these methods work, and which one applies to your situation, helps you see your business the way a buyer will, instead of anchoring on a number that has little to do with how the deal will actually get priced.
Part of our Exit Planning series. Start with Business Exit Planning: A Founder's Roadmap for the complete framework.
The three primary valuation methods, compared
Discounted cash flow (DCF). Projects future cash flows and discounts them back to present value using a rate that reflects risk. DCF is theoretically rigorous but highly sensitive to the growth and discount rate assumptions, which makes it easier to manipulate and harder to defend in a negotiation than a multiple grounded in comparable deals.
Asset-based valuation. Values the business based on the fair market value of its assets minus liabilities. This method matters most for asset-heavy businesses or distressed situations, and rarely drives price in a healthy, growing, founder-led business.
In practice, sophisticated buyers triangulate across methods but anchor primarily on EBITDA multiple for operating businesses, then adjust for quality of earnings, customer concentration, and owner dependence.
Why the same business can get two very different offers
It is common for a founder to receive wildly different informal valuations from different sources: a rule-of-thumb multiple from an industry peer, a higher number from a business broker eager to win the listing, and a lower number from a strategic buyer's initial indication of interest. These differences usually come down to what each party is actually applying the multiple to, and how much adjustment they are making for risk factors specific to your business.
A broker's early estimate is often based on top-line revenue multiples or optimistic EBITDA add-backs that have not yet been tested. A strategic buyer's diligence team will normalize EBITDA far more conservatively, removing one-time gains, adjusting owner compensation to market rate, and discounting for customer concentration or unclear financials. The gap between those two numbers is not dishonesty on either side. It reflects how much uncertainty exists in the underlying earnings before real diligence happens.
The practical takeaway is that any valuation estimate is only as strong as the earnings quality behind it. A founder who wants a credible number should assume a buyer's more conservative normalization will apply, and build the financial cleanliness that supports that number before ever starting a sale conversation.
Common mistakes founders make when estimating their own valuation
A third common mistake is failing to normalize EBITDA for owner-specific add-backs correctly. Some add-backs are legitimate, a one-time legal expense, for example. Others, like understating owner compensation to inflate reported profit, tend to get challenged and reversed during real diligence, which means they should not be counted on when estimating value informally either.
What most affects your applicable multiple
- Consistency and verifiability of reported EBITDA
- Customer or payer concentration
- Owner dependence across leadership and client relationships
- Revenue growth trajectory and its sustainability
- Industry-specific benchmark multiples for comparable transactions
- Quality and completeness of financial documentation
Getting a credible read on your own number
A useful first step before any formal valuation exercise is an assessment of the specific factors that move your multiple up or down: earnings quality, customer concentration, owner dependence, and growth trajectory. Understanding where your business currently sits on each of these dimensions gives you a far more actionable picture than a single multiple applied to your EBITDA in isolation.
The multiple itself is only half the equation. The EBITDA number it gets applied to has to survive scrutiny, which is where financial cleanliness and metrics becomes directly relevant: buyers discount or walk away from earnings they cannot verify.

Turn the concept into a decision
Exit planning is multidisciplinary and fact-specific. The useful next step is to organize the owner's goals, the company's evidence, the transition options, and the roles of qualified finance, tax, legal, valuation, wealth, and transaction professionals.
Questions to answer before choosing a next step
- What is the purpose of the valuation: planning, tax, partner transfer, financing, litigation, or sale? Write down the current answer, the evidence behind it, the person who can verify it, and the decision it changes. If the answer depends on an assumption, record what would make management revisit that assumption.
- Which earnings adjustments are supportable with records? Write down the current answer, the evidence behind it, the person who can verify it, and the decision it changes. If the answer depends on an assumption, record what would make management revisit that assumption.
- How dependent are revenue and operations on the owner or a few relationships? Write down the current answer, the evidence behind it, the person who can verify it, and the decision it changes. If the answer depends on an assumption, record what would make management revisit that assumption.
- Which method fits the purpose, business model, data, and available market evidence? Write down the current answer, the evidence behind it, the person who can verify it, and the decision it changes. If the answer depends on an assumption, record what would make management revisit that assumption.
- Who is qualified to provide the required level of valuation work? Write down the current answer, the evidence behind it, the person who can verify it, and the decision it changes. If the answer depends on an assumption, record what would make management revisit that assumption.
Records that make the discussion concrete
- several periods of financial statements and tax returns Confirm the source, reporting period, definition, completeness, and reconciliation owner before using it in a forecast or recommendation.
- a reconciliation of owner, related-party, and one-time items Confirm the source, reporting period, definition, completeness, and reconciliation owner before using it in a forecast or recommendation.
- debt, cash, working-capital, and capital-expenditure detail Confirm the source, reporting period, definition, completeness, and reconciliation owner before using it in a forecast or recommendation.
- customer, supplier, employee, and contract concentration Confirm the source, reporting period, definition, completeness, and reconciliation owner before using it in a forecast or recommendation.
- management, ownership, and legal records relevant to transferability Confirm the source, reporting period, definition, completeness, and reconciliation owner before using it in a forecast or recommendation.
Start with the records that already exist, note which definitions do not reconcile, and name one person responsible for each follow-up. A recommendation should state its assumptions and boundaries so management can revisit it when the facts change.
Run a documented working session
Begin the session with one decision and one deadline. Separate known facts from estimates, then identify the smallest set of records needed to resolve the uncertainty. This keeps the meeting from becoming a general review of every report and makes it easier to see whether the missing piece is data quality, operating ownership, or senior financial judgment.
Next, reconcile definitions before comparing figures. Terms such as revenue, production, adjusted earnings, capacity, backlog, payer mix, or working capital can mean different things across systems and teams. Record the definition used, the period covered, the source system, and any exclusions. A number that cannot be defined and traced should not drive a consequential recommendation.
End with a decision record rather than a slide deck alone. The record should name the decision owner, the recommendation, alternatives considered, assumptions, evidence, professional-review boundaries, actions, and the date for the next review. This creates an audit trail for management and lets the team learn when actual results differ from the original expectation.
Fields to preserve in the decision record
- Question and deadline: the exact choice management must make and when it becomes costly to delay.
- Evidence: the source records, reporting periods, definitions, and reconciliations used.
- Assumptions: the items that remain estimates and the events that would change them.
- Alternatives: realistic options, including the choice to wait or collect better information.
- Boundaries: tax, legal, regulatory, clinical, investment, or valuation conclusions that require another qualified professional.
- Follow-through: the owner, action, measurement, and next review date.
Keep the professional boundaries clear
Keystone provides strategic financial analysis, forecasting, coordination, and exit-readiness support. It does not prepare tax returns, provide legal advice, act as a registered investment adviser, guarantee a valuation or transaction, or replace the client's qualified professionals. Advice that depends on tax, legal, regulatory, clinical, investment, or formal valuation conclusions should be confirmed by the appropriate professional.
Exit preparation should preserve the difference between an internal planning estimate, a formal valuation, and an actual buyer proposal. Each may use a different date, purpose, standard, earnings definition, risk view, and transaction structure. Keep the source records and assumptions beside any estimate so another qualified adviser can understand how it was built. A business attorney should guide legal structure, confidentiality, contracts, and disclosure. A CPA or tax adviser should address tax consequences and reporting. A qualified valuation or transaction professional should provide the level of valuation or market work the situation requires. Keystone's role is to organize financial evidence, clarify operating risks, model choices, and coordinate the work around the owner's goals. No planning exercise guarantees buyer interest, financing, price, terms, timing, or closing. The practical value is better information, fewer avoidable surprises, and more time to choose among realistic options.

Questions owners ask about this topic
Is an EBITDA multiple enough to value a business?
No. A multiple is one input, and the earnings figure must first be normalized and supported. Purpose, industry, size, growth, risk, cash needs, concentration, owner dependence, and deal terms can change the analysis. Formal conclusions should come from a qualified valuation professional when the situation requires one.
Why can two valuations differ?
They may use different purposes, dates, standards, assumptions, earnings adjustments, methods, or definitions of value. A buyer's offer may also reflect structure and strategic considerations that differ from an independent planning valuation. Compare the scope and assumptions before comparing the headline number.
What does IRS Revenue Ruling 59-60 contribute?
Revenue Ruling 59-60 describes factors considered in valuing closely held stock for federal tax purposes, including the business history, financial condition, earnings capacity, dividend capacity, goodwill, comparable companies, and prior sales. It is an authoritative framework, not a calculator for every transaction.
