Business Valuation Methods: Why the Results Diverge
The market, income, and asset approaches can all be competently applied and still disagree.

The ownership interest and valuation date come first
A business valuation method can be calculated correctly and still answer the wrong question. A whole-company sale, a minority interest, and a federal tax valuation may draw from some of the same financial statements, but they do not necessarily value the same rights for the same purpose.
The three principal business valuation approaches are market, income, and asset-based. They can produce different results because they rely on different evidence and assumptions. Valuation standards also require the assignment to identify the interest being valued, its purpose, and its date before an approach is selected or reconciled. 123
Before comparing the answers, check that both calculations value the same ownership interest for the same purpose on the same date. Otherwise, you would be comparing two assignments rather than two methods.
One company, three business valuation results
This is a hypothetical example, not market evidence. Lakeview Field Services is fictional. The retained workpaper gives it a market indication of $2.52 million, an income indication of about $2.83 million, and an asset-based indication of $1.55 million.
The calculations disagree because they begin in different places. The market case applies a fictional 4.2x multiple to $600,000 of normalized EBITDA. The income case discounts $420,000, $450,000, and $480,000 of fictional annual cash flow, then adds a terminal value using an 18% discount rate and 2% long-term growth. The asset case starts with $2.30 million of supported assets and subtracts $750,000 of liabilities.
A result cannot prove its own inputs. Test comparable transaction facts for the market case, a deliverable forecast for the income case, and current support for asset ownership, values, and liabilities. Passing one test does not validate the others.
The $313,000 gap between the market and income approaches
Lakeview's income indication exceeds its market indication by roughly $313,000. Different assumptions, not rounding, create the gap.
The market result assumes that 4.2x is a useful comparison for this ownership interest and this $600,000 earnings figure. A reported transaction would need a clear price definition, earnings denominator, date, and set of rights before it could support that assumption. ASA's standards call for a reasonable basis for comparison and caution against substantial reliance on unsupported rules of thumb. 3
The income result depends on Lakeview producing the forecast cash flow and on 18% adequately reflecting the uncertainty in receiving it. A forecast that requires another sales hire, more working capital, or equipment spending has to include those demands. It also weakens if Lakeview's departing owner still carries customer or operating work that no one else is ready to perform.
Those inputs come from different documents and different judgment dates, so certainty in one calculation cannot repair weak support in the other.
A weak transaction comparison does not make the forecast right, and an optimistic forecast does not make the multiple right. Those two numbers tell you where to look: the sale facts behind 4.2x and the operating facts behind the forecast.
The asset result changes the question, not just the number
The asset indication sits $970,000 below Lakeview's market result and about $1.28 million below its income result. That does not prove the other two results are wrong. Earnings may depend on relationships, workforce knowledge, systems, or other advantages missing from the asset schedule. The gap may also expose an omitted liability or an unsupported asset value.
Reconciliation is the work of explaining those differences. ASA directs attention to the reliability of the data and assumptions behind each indication rather than to a mechanical average. 3 For Lakeview, that means checking whether the comparison includes the same price and earnings, the forecast survives the owner's departure, and the asset schedule captures every owned asset and obligation.
If you are still building an early range, the business-worth guide shows how one earnings case turns into value and initial cash. The valuation desk collects the narrower earnings, method, and offer questions. For Lakeview, the next step is to identify the assumption behind the largest unexplained difference. A method deserves more weight only after the assumption doing the most work has the evidence to carry it.
