SDE vs EBITDA: One Business, Two Numbers
On this page
Research date: September 18, 2026.
Seller’s discretionary earnings (SDE) and earnings before interest, taxes, depreciation and amortization (EBITDA) describe the same year of trading and produce different numbers. The difference is one line: how the person running the business is treated.
TL;DR: SDE adds one working owner’s compensation back into earnings. EBITDA leaves management compensation as a business cost. On the same year, and with every other adjustment held constant, SDE exceeds EBITDA by the owner’s compensation. SDE is the usual metric for owner-operated businesses and EBITDA for businesses that run on a management team. A multiple built on one metric cannot be applied to a figure calculated with the other.

What is the difference between SDE and EBITDA?
| SDE | EBITDA | |
|---|---|---|
| Owner’s compensation | Added back — one working owner | Expensed — management is a cost |
| Usual application | Owner-operated businesses | Businesses with a management layer |
| Where it is usually quoted | Broker listings and marketplace summaries | M&A processes and larger credits |
| Relationship, adjustments held equal | SDE = EBITDA + the owner’s compensation | EBITDA = SDE − the owner’s compensation |
The middle rows describe where each metric is conventionally used, which is an observation about market practice rather than a rule anyone publishes. The bottom row is arithmetic, and it holds where both figures are normalized the same way in every other respect and the business has one working owner. It stops holding once a second owner draws a salary, because SDE adds back one of them.
One business, carried through both
A distribution business, one working owner, one year. The figures are illustrative and internally consistent; they are not drawn from a transaction.
| Line | Amount |
|---|---|
| Net profit on the tax return | $180,000 |
| Add interest | $35,000 |
| Add depreciation and amortization | $140,000 |
| EBITDA | $355,000 |
| Add documented discretionary spending | $80,000 |
| Adjusted EBITDA | $435,000 |
| Add the owner’s compensation and payroll taxes | $265,000 |
| SDE | $700,000 |
Three figures, all arithmetically correct, all describing the same business. The owner’s $265,000 is what separates SDE from adjusted EBITDA. The discretionary spending is what separates adjusted EBITDA from EBITDA itself — worth noticing, because a figure a listing calls “EBITDA” is frequently the adjusted one, and the adjustments are rarely itemized beside it.
Note what the owner’s line is and is not. It is what this owner was actually paid. It is not the market rate for the role, which is a separate figure and usually a different one — and it is the market rate, not the historical pay, that a lender deducts when it builds its own cash flow. A seller paying themselves well below market produces an SDE that flatters the business by exactly that gap.
Why can a multiple not travel between the two?
This is where the arithmetic goes wrong in practice, and it goes wrong in the direction that costs a buyer money.
Suppose a broker quotes the business at 3.5× SDE, and the buyer — working from an EBITDA rule of thumb they read elsewhere — reaches for 5× instead. The two multiples below are illustrative, chosen to show the error rather than to state what any business is worth:
- 3.5 × $700,000 = $2,450,000
- 5 × $435,000 (the adjusted EBITDA above) = $2,175,000
- 5 × $700,000 = $3,500,000
The third line is the mistake: an EBITDA multiple applied to an SDE figure. It lands more than a million dollars above the first, and the error is invisible unless somebody names which metric each number came from.
A multiple is calibrated to a metric. Moving one without the other is not a valuation, it is a category error. This page sets no multiple: published ranges vary by industry, by data source and by year, and a range quoted without its source and its date is not evidence.
Which one does a lender use?
Neither, directly. A lender starts from whichever figure the seller presents, then builds its own bridge: it removes add-backs the records do not support, deducts a market-rate salary for whoever runs the business, deducts maintenance capital spending, and counts any debt the business keeps after closing.
That bridge is the same whichever metric it starts from. Starting at SDE makes the salary deduction explicit and large. Starting at EBITDA means it is already inside the number, at whatever the business actually paid. Either way the endpoint is cash flow for debt service, which is what a coverage ratio is computed on.
Under the incoming SOP 8.1 framework, the SBA’s acquisition appendix defines its own historical coverage test as EBITDA over combined post-transaction debt service, with adjustments that have to be supported. That is a program rule rather than a market convention. SOP 8.1, Appendix 15; how the test applies by transaction category
Which metric applies to your target?
No rulebook draws the line. As a working rule:
- Owner-operated, one person central to the business. SDE. The buyer is purchasing a job and a return, and the metric says so.
- A management team already runs it without the seller. EBITDA. Management is a genuine cost that continues after closing, so expensing it describes the business a buyer actually receives.
- Somewhere between. Calculate both and label each one. A seller who works twenty hours a week is the hard case, and no metric resolves it alone.
What SDE includes, and which add-backs survive verification sets out the ledger behind the first of those.
Frequently asked questions
Which metric gives the higher number, SDE or EBITDA?
SDE, on a business with one working owner, by that owner’s compensation. A higher number on the same business is not a better business, and the multiple applied to it is calibrated accordingly.
Can I convert a quoted EBITDA into SDE?
Only with the owner’s compensation line in front of you. Without it the conversion is a guess, and a guess in this position moves the implied price by the full amount of the salary.
Does the metric change what the business can borrow?
No. Debt capacity depends on cash flow after the lender’s deductions, which is the same destination from either starting point. The metric changes the price conversation, not the cash the business produces.
Name the metric before you name the price
Ask which metric a quoted figure is, ask whose compensation is inside it, and ask what the market rate for that role would be. Then apply a multiple built on the same metric, or convert first and say that you did.
The valuation and SDE calculator starts from a declared basis and refuses an add-back that basis has already excluded, which is the double-count this page describes. The DSCR calculator carries the result through to coverage.
Neither states what a lender will do. Duneland does not extend credit, and every structure remains subject to a lender’s own underwriting. Bring a defined transaction to a financing review with the earnings basis identified.
