Understanding EBITDA: Why Sustainable Earnings Matter More Than Owner's Discretionary Income

An owner's guide to the difference between operating profit and the combined financial benefit of owning and working in a business.

A Business Is More Than a Job

Many small businesses are purchased by individuals who intend to step directly into the seller's shoes. They expect to manage the company themselves, perform many of the seller's duties, and receive the financial benefits previously enjoyed by the owner.

For these buyers, Seller's Discretionary Earnings (SDE) can appear to be an attractive measure of the income available from the acquisition.

But there is an important distinction that is frequently overlooked.

The financial benefit of owning and working in a business is not the same as the profit generated by the business itself.

If a business produces $400,000 in SDE but requires management services reasonably worth $150,000 annually, its sustainable operating earnings after allowing for those services are closer to $250,000, assuming no other adjustments.

A buyer who personally assumes those duties may enjoy the full $400,000 in combined compensation and business earnings. However, $150,000 of that amount represents the economic value of the buyer's own labor.

That distinction becomes especially important if the buyer later wishes to hire management, reduce personal involvement, or sell the company to someone who does not intend to operate it personally.

The business may be an attractive acquisition for an owner-operator, but its underlying profitability should still be measured after recognizing the reasonable cost of the management necessary to operate it.

For this reason, I prefer to evaluate privately held businesses using normalized EBITDA, with appropriate compensation for necessary management responsibilities.

SDE remains useful for understanding the economics of an owner-operated acquisition, but it should not be confused with the sustainable earnings of a business operating independently of its owner.

What Is EBITDA?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization.

It is one of the most widely used measures of operating profitability when evaluating privately held businesses.

The purpose of EBITDA is to provide a more consistent basis for comparing the earnings of businesses that may have different financing arrangements, tax circumstances, and accounting treatments.

A common calculation begins with net income:

EBITDA = Net Income + Interest Expense + Income Tax Expense + Depreciation + Amortization

This simplified calculation assumes no other nonoperating income or expense adjustments. When starting from operating income rather than net income, interest and income taxes ordinarily have already been excluded.

Each adjustment serves a purpose.

Why Interest Is Excluded

Consider two otherwise identical companies. One has substantial bank debt and pays $100,000 annually in interest. The other operates without debt.

Their operating performance may be identical, but the heavily leveraged company will report lower net income because of its financing costs.

That difference does not necessarily indicate that one company is a better operating business than the other.

In many business acquisitions, the purchase price is negotiated on a cash-free, debt-free basis, with existing financial debt retired at closing or otherwise addressed in the transaction.

By excluding interest expense, EBITDA allows buyers to evaluate operating earnings independently of the seller's financing decisions.

Why Income Taxes Are Excluded

Businesses can have very different income tax obligations, even when their operating results are similar.

For example, a C corporation pays federal income taxes at the corporate level, while an S corporation generally passes its taxable income through to its shareholders.

Tax obligations can also differ because of ownership structures, tax elections, and other circumstances.

These differences do not necessarily reflect the underlying operating performance of the businesses.

EBITDA therefore measures earnings before income taxes, allowing buyers to compare companies without confusing operating profitability with differences in tax treatment.

Why Depreciation and Amortization Are Excluded

Depreciation and amortization are noncash accounting expenses that generally allocate the historical cost of assets over their estimated useful lives.

These expenses can vary significantly between businesses because of asset age, acquisition history, accounting methods, and other factors.

Adding them back provides another level of consistency when comparing operating earnings.

However, there is an important qualification.

Depreciation may be a noncash accounting expense, but replacing equipment is a very real cash expenditure.

A business requiring substantial ongoing investment in machinery, vehicles, or equipment may generate less cash for its owners than another business with identical EBITDA but lower capital expenditure requirements.

For this reason, EBITDA should always be considered alongside the company's actual reinvestment needs.

What EBITDA Tells Us

EBITDA provides a useful starting point for evaluating the earning capacity of an operating business before financing costs, income taxes, depreciation, and amortization.

It does not represent cash flow, nor does it establish business value by itself.

To assess sustainable profitability, EBITDA may also require adjustments for reasonable management compensation and properly substantiated nonrecurring expenses.

The objective is to determine what the business can reasonably be expected to earn under normal operating conditions, regardless of the current owner's financing arrangements or personal circumstances.

The Importance of Management Compensation

Consider two privately held businesses with similar operations and financial results. Company A is managed by its owner, who receives $150,000 annually. Company B employs a general manager who receives $150,000 annually. Both companies generate $500,000 before deducting management compensation.

The businesses have the same EBITDA after accounting for management. Company A should not automatically command a higher value merely because the person performing the management duties owns the company.

If the owner leaves, the buyer must either perform those duties personally or hire someone to do so. Either way, those responsibilities have an economic cost.

The appropriate management compensation adjustment should reflect the duties actually performed and the reasonable market cost of replacing those services. It should not automatically equal the seller's historical salary.

Why I Prefer EBITDA to Seller's Discretionary Earnings

SDE generally adds back one working owner's compensation and certain benefits, along with other qualifying adjustments. It is frequently used in smaller, owner-operated business transactions.

The difficulty is that SDE can create an exaggerated impression of the earnings available from the business if the reader overlooks the work the owner performs.

In our example, Company A might report SDE of $500,000, even though its EBITDA after management compensation is $350,000.

The additional $150,000 does not represent earnings that a passive buyer could necessarily retain. Someone still has to manage the business.

SDE can be useful when evaluating the combined financial benefit of ownership and employment. But I believe EBITDA, adjusted for reasonable management compensation, provides a more meaningful foundation for understanding the value of the operating enterprise.

Why SDE and EBITDA Multiples Differ

Businesses valued using SDE commonly sell for lower multiples of SDE than otherwise comparable businesses valued using EBITDA. That should not be surprising: SDE generally represents a larger earnings figure because it excludes one working owner's compensation.

For illustration, consider a hypothetical business valued at $1,400,000.

The business has not changed, and neither has its selling price. Only the earnings measure used in the calculation has changed.

A multiple of SDE should never be compared directly with a multiple of EBITDA without understanding the difference in the underlying earnings.

Normalizing Earnings

Reported EBITDA sometimes requires adjustments to better reflect the company's sustainable earning capacity.

For example, an owner may receive compensation substantially above or below the reasonable market cost of performing their duties. In that case, the valuation analysis should consider the actual responsibilities involved and the compensation required to replace them.

This is different from simply adding back the owner's entire salary.

Likewise, genuinely unusual or nonrecurring expenses may warrant adjustments when supported by adequate documentation.

Personal expenses charged to the business deserve particular scrutiny. A seller may contend that certain expenditures are unrelated to operations, but buyers and lenders may reject unsupported adjustments. Such expenses can also raise accounting, tax, and credibility concerns.

The objective should not be to produce the largest possible adjusted earnings figure.

The objective is to determine what the business can reasonably be expected to earn under normal ownership and management.

EBITDA Is Not Cash Flow

Even properly adjusted EBITDA does not tell the entire story. Businesses must replace equipment, maintain facilities, invest in technology, and fund inventory and receivables.

A company generating $500,000 of EBITDA but requiring substantial annual capital expenditures may produce less cash for its owners than another company with the same EBITDA and minimal reinvestment requirements.

Working capital requirements can also have a significant impact. For these reasons, buyers evaluate EBITDA alongside capital expenditure needs, working capital, debt obligations, and other demands on cash.

Earnings Are Only Part of Business Value

Two businesses with identical EBITDA may have substantially different market values.

Consider a company with experienced management, a diversified customer base, long-tenured employees, and a strong reputation. Now compare it with a business earning the same amount but dependent on one owner, two major customers, and a single critical supplier.

Their reported earnings may be identical, but the risks associated with sustaining those earnings are very different. Buyers recognize those differences, and the prices they are willing to pay will reflect them.

The Bottom Line

For privately held business owners, understanding EBITDA is an important step toward understanding business value. But the number should represent realistic, sustainable earnings—not an optimistic collection of adjustments designed to produce the highest possible valuation.

A business that can generate dependable earnings after paying the people necessary to operate it is generally more attractive than one whose apparent profitability depends on an owner working without adequate compensation.

The ultimate goal is to build a business that produces earnings because of the organization you have created, not merely because of the hours you personally contribute.
