Which earnings metric a buyer applies to your business depends on scale and how involved you are in daily operations. SDE is used for owner-operated businesses where one person is central to the work. EBITDA is used once there is a real management team and the owner is one of several leaders. The choice changes your headline number substantially, so it is worth knowing which side of the line you sit on.
Both metrics are attempts to answer the same question: how much cash does this business actually produce for whoever owns it? They differ in one assumption, which is whether the owner's own labour is a cost of running the business or a benefit of owning it.
What is SDE?
SDE, or seller's discretionary earnings, is roughly EBITDA plus one full-time owner's total compensation. It measures the entire financial benefit a single working owner extracts from the business, including salary, payroll taxes on that salary, and discretionary personal expenses run through the company.
The logic is that a buyer of a small, owner-operated business is buying themselves a job as well as an asset. They will step into the owner's role, so the money the previous owner paid themselves becomes money available to the new owner. Treating that compensation as a business expense would understate what the buyer actually gets.
SDE is the larger number for any given business, because it adds compensation back rather than charging it. That is precisely why the multiples applied to SDE are lower than those applied to EBITDA. The two conventions are calibrated to land in a similar place.
What is EBITDA?
EBITDA is earnings before interest, taxes, depreciation, and amortization. It measures what the business earns after paying market-rate management, stripped of the financing and tax choices specific to the current owner.
The assumption is different from SDE's. An EBITDA buyer is not planning to run the business personally. They are acquiring an operation that already runs itself, or they intend to install a manager. Management is therefore a genuine ongoing cost, and the earnings figure has to carry it.
This is why EBITDA is the convention once a business has real management depth. It answers the question that matters to an institutional buyer: what does this business earn as a standalone operation, independent of who owns it? For a fuller treatment of how buyers build that figure and apply a multiple to it, see how buyers value a privately held business.
EBITDA and SDE side by side
| SDE | EBITDA | |
|---|---|---|
| Full name | Seller's discretionary earnings | Earnings before interest, taxes, depreciation and amortization |
| Owner compensation | Added back — one working owner's pay returns to earnings | Charged as a cost — the business pays a market rate for the role |
| Assumes the buyer | Steps into the owner's job | Inherits a management team |
| Typical business | Smaller, owner-operated | Established, with a management layer |
| Typical earnings figure | Larger, because owner pay is added back | Smaller, because that pay is deducted |
| Typical multiple | Lower | Higher |
| Applying the other one's multiple | Inflates the result | Understates the result |
The last row is the one that costs owners money. The two conventions are internally consistent and not interchangeable: a larger earnings figure carries a lower multiple precisely because it already includes the owner's pay.
How do buyers decide which one applies?
Two things decide it: the size of the business and how much of it depends on you.
Scale is the coarser signal, and the market segments itself accordingly. The IBBA and M&A Source Market Pulse survey, a quarterly study of closed transactions reported by business brokers and M&A advisors, splits its reporting between a Main Street segment covering businesses valued at $0 to $2 million and a lower middle market segment covering $2 million to $50 million. Those two segments attract different buyers with different assumptions, and in our experience the earnings convention tends to follow the same boundary: SDE below it, EBITDA above.
Owner involvement is the finer signal, and it matters more than the revenue figure. A business at the top of the Main Street range that genuinely runs without its owner may be assessed on EBITDA. A larger business where the owner personally holds the key customer relationships and makes every significant decision may be assessed on SDE regardless of its revenue, because the earnings are not separable from the person.
The practical test is simple. If the business would need to hire someone to replace what you do, EBITDA is the honest frame, and the cost of that hire belongs in the numbers. If a buyer would step directly into your role, SDE is the honest frame.
Why does the choice change your headline number?
Because the two metrics multiply different things by different factors, and comparing headline figures across conventions is meaningless.
SDE produces a larger earnings base, since it adds owner compensation back rather than charging it, and it carries lower multiples. EBITDA produces a smaller earnings base and carries higher multiples. Run honestly, both routes should land in a broadly similar place for the same business. The conventions are two roads to one destination.
The trouble starts when the two get mixed. An owner who hears a multiple quoted for lower-middle-market EBITDA deals and applies it to their own SDE figure will arrive at a number well above anything a buyer would offer, because they have combined the larger earnings base with the higher multiple. This is one of the most common sources of expectation gaps in small-business sales, and it is entirely avoidable.
Whenever you see a multiple quoted anywhere, the first question is which earnings figure it applies to. A multiple without a stated denominator is not usable information. That caution applies to published multiple tables generally, as covered in EBITDA multiples by industry.
How is owner compensation treated in each?
SDE adds one working owner's compensation back to earnings; EBITDA instead charges the business a market rate for that role. This is the single adjustment that separates the two metrics, and it is worth understanding precisely.
Under SDE, one working owner's full compensation is added back to earnings. Salary, the payroll taxes on it, and genuine discretionary spending all return to the earnings figure, because a buyer-operator would capture those benefits.
Under EBITDA, the business is charged a market rate for the management role instead. Compensation above that market rate is added back, and compensation below it is subtracted. An owner paying themselves far under market is quietly flattering their reported earnings, and a buyer will correct for that during diligence.
What counts as a market rate is a question with real scrutiny behind it. The IRS maintains guidance for its own valuation professionals on determining reasonable compensation, published alongside its other valuation job aids, which is a reminder that this figure gets tested rather than asserted. The broader set of adjustments a buyer makes is covered in EBITDA add-backs buyers accept and reject.
Note that SDE adds back one owner's compensation. Businesses with two or three active owner-operators do not get to add back all of them, because a single buyer cannot replace three people. Additional owners are treated as employees whose replacement cost stays in the numbers.
What if your business sits near the boundary?
Have it assessed both ways, and treat the gap between the two answers as information rather than a contradiction.
Businesses near the line often attract two different kinds of buyer. An individual operator will price on SDE, because they intend to run the business. A smaller institutional buyer or a strategic acquirer will price on EBITDA, because they intend to install management. Those two buyers can arrive at genuinely different numbers for the same business, and neither is wrong.
The size of the gap is itself diagnostic. A large gap means a lot of your earnings depend on your personal involvement, which is exactly the condition that caps a multiple and narrows the buyer pool. Closing that gap by building management depth is one of the most reliable ways to move from the SDE frame into the EBITDA frame, and businesses that make the transition usually find both the earnings base and the buyer pool improve. That is also why the answer is always expressed as a range: see why a buyer's offer is rarely a single number.
What this means for your estimate
Our valuation calculator uses EBITDA throughout, which suits businesses with management depth and earnings that do not depend on one person.
If you are in SDE territory, the estimate is still useful, but read it as a directional ceiling rather than a midpoint, and discount for the owner involvement the model is not pricing. The more of the business that runs through you personally, the further from the estimate a real offer is likely to land.
Either way, treat the output as a starting point for a more specific and confidential conversation, not as a formal appraisal.
