Why the measure exists at all. A business with one working owner reports a profit that says more about the owner's tax planning than about the business. The same operation can show a $30,000 profit while paying the owner $200,000 in salary, or a $200,000 profit while paying $30,000, and nothing about the underlying operation has changed. A buyer is not buying the profit line; they are buying the total benefit the business can deliver to one person who will both own it and work in it. Seller's discretionary earnings is an attempt to state that total in one number.
The one-owner rule is the element most often stated wrongly, and it runs in both directions. IBBA adds back "one owner's entire compensation," not every owner's. Its separate entry for the quantity being added back makes the asymmetry explicit: Owner Total Compensation is the "total of an owner's salary and perquisites, after the compensation of all other owners has been adjusted to market value." So a two-owner business adds back the working owner's whole package and then restates every other owner's pay at market. Where a second owner has been drawing less than a market wage for real work, that restatement is a subtraction, and the resulting figure is lower than the naive add-everything-back version. A page or a broker's package that adds back all owners' pay is describing a business that will need to hire replacements the buyer has not been told about.
What counts as a discretionary or nonrecurring add-back, and where the argument happens. The uncontroversial items are mechanical: interest, income taxes, depreciation, amortization. The contested ones are the judgment calls, and they are where a seller's number and a buyer's number diverge:
- Owner perquisites run through the business. A vehicle, a phone, travel with a personal component, family members on payroll for work the buyer would not need done.
- Nonrecurring items. A one-time legal settlement, a flood repair, a single large bad debt. Each is a legitimate add-back if it genuinely will not recur, and each is a place to inflate the number if it will.
- Discretionary spending the buyer might not continue: charitable contributions, a conference the owner enjoys, above-market rent paid to an entity the owner also owns.
- Expenses the buyer will actually incur. This is the trap in reverse. If the seller works sixty hours a week and the buyer intends to hire a manager, the manager's salary is a real future cost, and adding back the seller's pay without noting the replacement cost overstates what the buyer will earn.
How a multiple gets applied, and what it does not mean. Small businesses are commonly priced at some multiple of this figure. The multiple is a market observation, not a rule, and it moves with the industry, the size of the business, how concentrated its customers are, how transferable the owner's role is, and credit conditions at the time. Two consequences follow. First, every dollar added back is a dollar multiplied, so an aggressive add-back list is worth several times its own size to the seller, which is why the add-back schedule is negotiated rather than calculated. Second, a multiple applied to a number computed on different conventions than the multiple was derived from produces a meaningless answer.
Where it sits among the other measures. Earnings before interest, taxes, depreciation and amortization is the same idea without the owner-compensation add-back, which is why it is the measure used for businesses large enough to have professional management already priced into the expenses. A larger business is usually quoted on earnings before interest, taxes, depreciation and amortization; a smaller owner-operated one on seller's discretionary earnings. Neither is a cash flow statement figure and neither accounts for what the business must spend on equipment to keep running, so a capital-intensive business can carry a healthy figure and very little money available to a new owner after replacing assets.
