Two companies, each generating $500,000 in reported net income, one with a paid CEO earning market-rate compensation, and one operated by its founding owner drawing a nominal salary of $50,000 while performing every senior function. Their reported earnings look similar, but their economic earnings are dramatically different. This is the problem that Seller's Discretionary Earnings (SDE) is designed to solve. SDE is the standard earnings normalization metric for owner-operated businesses, particularly those with revenues under $5 million, and it is the foundation upon which the vast majority of small business valuations and transactions are built.
SDE starts with pre-tax net income and adds back four categories of items: depreciation and amortization, interest expense, the owner's total compensation (salary, bonuses, distributions, and any personal benefits run through the business), and all non-recurring or discretionary expenses. The resulting figure represents the total economic benefit available to a single working owner, that is, what the business would generate for an owner-operator who replaces the current owner in every capacity. It is, in essence, the maximum cash flow available to a full-time buyer who intends to operate the business themselves.
The key distinction between SDE and EBITDA is the treatment of owner compensation. EBITDA adds back depreciation, amortization, and interest, but leaves owner compensation in the expense base, typically replaced by a market-rate management salary in the normalization process. SDE adds back all owner compensation because it assumes the buyer will step into the owner's shoes entirely, capturing both the return on investment and the return on labor in one figure. This makes SDE more appropriate for businesses where a single owner-operator is central to operations. For larger businesses with a professional management team in place, EBITDA, normalized for market-rate management costs, is the more accurate and relevant metric.
Businesses sold in the small business market are almost universally priced as a multiple of SDE. A buyer acquiring a business for 3.0x SDE of $400,000 is paying $1.2 million, and expects to earn both a management income and a return on investment from the business. Applying an EBITDA multiple to a small owner-operated business without first replacing owner compensation with a market-rate management cost will materially overstate value. Conversely, applying a conservative EBITDA-based valuation to a business where the owner also functions as the key salesperson, operations manager, and financial controller will understate what that business is actually worth to a buyer who intends to operate it. Selecting the right earnings metric, and applying it consistently with how the comparable transaction data was compiled, is one of the most fundamental disciplines in small business valuation. At ValuEdge, this distinction is built into the analytical framework from the outset, not addressed as an afterthought.
