SDE vs. EBITDA: Which One Actually Prices Your Business Sale

The gap is one line item

Run the same pre-tax P&L through both definitions and the gap between SDE and EBITDA comes down to a single line: one owner’s total compensation. Both figures add back interest, depreciation, and amortization — that part is identical. EBITDA (per the SEC’s non-GAAP measure definition) stops there. SDE (per the IBBA’s glossary) goes one step further and adds back the owner’s entire pay on top.

Why the gap exists

The two figures encode two different assumptions about who runs the business after a sale. EBITDA assumes management is a real, ongoing cost — the buyer inherits a paid manager or executive team, so that cost stays in. SDE assumes the opposite: in an owner-operated business, the buyer typically replaces the owner personally, working the job themselves rather than hiring someone to do it — so the owner’s pay is added back as money the buyer could keep instead of pay out. Neither assumption is wrong; they’re just describing different kinds of businesses.

The size convention

Which figure the market actually prices a deal on follows a documented size convention, per the IBBA & M&A Source Market Pulse Report: businesses valued under roughly $2,000,000 — the “Main Street” segment this site is built for — are priced on SDE multiples. The lower middle market above that, up to roughly $50M in enterprise value, is priced on adjusted EBITDA multiples instead. It isn’t an arbitrary line: below it, businesses are small enough that an owner-operator buyer is the realistic default; above it, professional management is the norm either way.

Adjusted EBITDA — the bridge back

For a business that sits near that line, adjusted EBITDA — SDE minus a market-rate replacement salary for the owner’s role — is the bridge between the two worlds. It answers “what would this business earn if it had to pay a real manager instead of an owner-operator,” which is the number a lower middle-market buyer will actually want to see if your business is priced close to the boundary.

Why this matters for a seller

Using the wrong figure with the wrong multiple range moves your estimate in a direction that hurts you either way: applying an EBITDA-style multiple to an SDE figure overstates the price (SDE is already the bigger number, so multiplying it by a multiple meant for the smaller EBITDA figure inflates the result past what a real buyer will pay); applying an SDE multiple to EBITDA understates it. A buyer sophisticated enough to know the difference will catch the mismatch immediately — so matching figure to convention isn’t a technicality, it’s table stakes for being taken seriously in the negotiation.
