The difference is one line: SDE adds back the owner’s entire compensation. Adjusted EBITDA adds back only the part above what a hired manager would cost. Everything else about the two numbers follows from that, including the fact that their multiples are not comparable and never were.
If your business needs you in it every day, SDE is the honest measure — it tells a buyer-operator what the job will pay them. If your business runs without you, adjusted EBITDA is the measure, because the buyer is purchasing cash flow rather than employment. Being quoted on the wrong one is not a rounding error. On the invented company below it is a $15 million difference in price.
The two definitions, side by side
Both start from the same place: pre-tax earnings, with interest, taxes, depreciation and amortization removed. They part company at the owner’s pay.
| Seller’s discretionary earnings (SDE) | Adjusted EBITDA | |
|---|---|---|
| Owner’s salary and bonus | Added back in full | Added back only above market replacement cost |
| Question it answers | What will this business pay the person who runs it? | What will this business earn for an owner who does not run it? |
| Assumed buyer | One individual, working in the business full time | A financial or strategic buyer installing or keeping management |
| Also called | Discretionary earnings, owner benefit, adjusted net | Adjusted EBITDA, normalized EBITDA |
| Typical quote format | A multiple of SDE | A multiple of trailing twelve-month adjusted EBITDA |
The add-backs that are not owner compensation — personal expenses run through the company, above-market related-party rent, genuinely one-time professional fees — work the same way in both measures, and they are governed by the same evidence standard either way. Which add-backs survive diligence and which get struck is a separate fight and a longer one.
Converting between them is one subtraction
SDE minus the cost of replacing yourself equals adjusted EBITDA. “Cost of replacing yourself” means the fully loaded package for a general manager who could do your job — salary, payroll taxes, benefits, bonus — not your salary, and not what you think the role is worth.
That subtraction is why the two numbers diverge most for the owners who think they are worth the least. An owner drawing $150,000 while doing a $400,000 job has an SDE figure that flatters the business by $250,000 a year. An owner drawing $900,000 for a role a $300,000 manager could fill has the opposite problem on paper, and a much better business underneath it.
Why you cannot move a multiple across the gap
This is the error that costs real money: taking a multiple quoted against one measure and applying it to the other.
The multiples differ because the metrics are not the same kind of thing. An SDE multiple is applied to a number that includes the buyer’s own wages. Part of what the buyer is “earning” is a salary they would have earned anywhere, so the multiple they will pay is low — they are buying a job with a business attached. An adjusted EBITDA multiple is applied to a number with the management cost already taken out, so every dollar of it is return on capital, and buyers pay far more for it.
For scale on the second kind of number: GF Data’s contributing private equity firms reported 80 completed transactions in the first quarter of 2026 at an average valuation of 7.3x trailing 12-month (TTM) adjusted EBITDA. GF Data draws on private-equity-sponsored transactions in the $1 million–$500 million enterprise value range. Sector matters on top of that; the bands in EBITDA multiples by industry and the business valuation calculator will give you a starting figure to test your own numbers against.
A worked comparison, on a company that does not exist
Invented numbers, invented company. The arithmetic is the point.
A distributor with $18,000,000 of revenue reports $2,100,000 of pre-tax income, after $350,000 of interest and $600,000 of depreciation and amortization. The owner takes $750,000 in salary and bonus, runs $140,000 of personal vehicles, travel and club dues through the company, and settled a single employment claim last year for $110,000. A general manager who could run the place costs $325,000 fully loaded.
| Line | SDE | Adjusted EBITDA |
|---|---|---|
| Pre-tax income | $2,100,000 | $2,100,000 |
| Interest | $350,000 | $350,000 |
| Depreciation and amortization | $600,000 | $600,000 |
| Owner’s compensation | $750,000 (all of it) | $425,000 (the part above $325,000) |
| Personal expenses | $140,000 | $140,000 |
| One-time settlement | $110,000 | $110,000 |
| Earnings measure | $4,050,000 | $3,725,000 |
| Multiple applied | 3.0x (an invented quote) | 7.3x (GF Data Q1 2026 average) |
| Implied price | $12,150,000 | $27,192,500 |
The gap between the two earnings figures is $325,000 — exactly the general manager. The gap between the two prices is $15,042,500, and nothing about the business changed between the columns. One column describes a job; the other describes an asset.
The 3.0x is made up, as the company is. The 7.3x is not. That asymmetry is deliberate: there is no published, reliable dataset of private-company SDE multiples at this size, and anyone quoting you a precise one is quoting their own book.
The line is not a revenue threshold. It is the buyer pool.
Owners look for a size at which the market switches measures. There isn’t one. What actually switches is who can write the cheque, and that is a financing question.
The SDE world is largely an SBA-financed world: one individual buying one business and running it. SBA 7(a) loans can be used for “changes of ownership (complete or partial),” and “the maximum loan amount for a 7(a) loan is $5 million.” Look again at the invented company. Even at the lowball $12,150,000 price, a $5 million ceiling leaves more than $7 million for the buyer to find in equity and seller paper — which is why a business at that level rarely trades to a buyer-operator at all, whatever measure the listing used.
Above the SBA ceiling the buyers are funds, strategics, family offices and management teams backed by debt. All of them underwrite against earnings after management cost, because all of them are hiring the management. How private equity actually finances a buyout walks through what that capital stack looks like, and management buyout financing covers the version where the buyer is already on your payroll.
So the practical test is not revenue and not EBITDA. It is: if you stopped coming in on Monday, what would break? If the answer is “most of it,” you have a business that will be priced on SDE no matter what you call it, and the highest-return project available to you is making that answer false before you go to market.
Why a financial buyer will not accept an SDE number
SDE is not dishonest. It answers a real question for a real buyer. It is simply the wrong instrument for a buyer who is not going to work in the business — because it adds back a cost that continues after closing.
The SEC has written the cleanest available standard on this for public companies, and the logic carries. Its staff treats a measure that excludes “normal, recurring, cash operating expenses necessary to operate a registrant’s business” as one that “could be misleading,” and defines recurring broadly: an operating expense that “occurs repeatedly or occasionally, including at irregular intervals” is recurring. Somebody has to run the company every week of every year. There is no more recurring expense in the business.
What happens in practice is not an argument. A buyer’s analyst rebuilds the model against adjusted EBITDA before the first call, the lender sizes debt off the same figure, and the number you were quoted never appears in the process again. You find out at the indication stage, having already spent months anchored to a price that was never on offer. How PE firms value a company sets out the order those steps happen in.
Four questions for whoever hands you a number
- Which measure is this, in one word? “Cash flow,” “owner benefit” and “adjusted net” are usually SDE. If the person cannot say which, the number is a listing tool, not a valuation.
- What replacement management cost did you deduct? There is only one right answer to this and it is a dollar figure with a source behind it.
- Is the multiple you quoted drawn from transactions measured the same way? An EBITDA multiple from middle-market data applied to an SDE figure is the single most expensive mistake in this subject.
- Does my own salary stay in the business after closing? If the buyer expects you to leave, your full pay is a cost they will incur. If they expect you to stay for three years, you are negotiating two things at once — price and employment — and should know which is which.
If the answers are vague, that is information about the advisor rather than about your company. Choosing an M&A advisory firm covers what to ask before you sign an engagement letter.
Frequently asked questions
At what size does the market stop using SDE? There is no official threshold, and brokers and bankers draw it in different places. The usable version is behavioural rather than numeric: SDE persists as long as the plausible buyer is an individual who will work in the business, and that pool is bounded by what one person can finance. Once a price needs institutional capital, the measure is adjusted EBITDA.
I already pay myself a market salary. Are SDE and EBITDA the same for me? Close, but check two things. SDE conventionally adds back the compensation of one owner-operator; if there are two or three family members on the payroll, the measures diverge again. And “market” has to mean the market for the role you actually perform, not the title on your business card.
Is a broker’s SDE figure useless to me? No. It is a correctly built number answering a different question, and the add-back work underneath it is reusable. Take the schedule, deduct a documented replacement management cost, and you have the starting point for an adjusted EBITDA figure. What you cannot reuse is the multiple.
Which number do lenders use? Adjusted EBITDA, in essentially every case above the SBA ceiling, because debt service has to come out of cash flow that exists after someone is paid to run the company.

The bottom line
SDE and adjusted EBITDA are two answers to two different questions, and the whole of the difference is the cost of the job you do. Work out which question applies to your business before anyone quotes you a multiple, because the multiple is the part that cannot be moved between them.
An Independent Buyout sits firmly on the adjusted EBITDA side of that line. The financing is sized off the company’s own cash flow after management is paid, so the structure only works for a business that runs without its owner — and when it does, the equity moves to a trust owned by the employees, existing leadership keeps running the company, and there is no sponsor and no exit clock attached to the money.
If your company does $3M+ in EBITDA and you want a straight read on which number your business should be priced on, talk to IBO Advisors.
