SDE vs EBITDA: which one matters when you're buying a small business?

You've probably seen a listing quote "3.2x EBITDA" and another quote "3.5x SDE" for businesses that look about the same size, and wondered which one is the better deal. It's a fair question, because SDE and EBITDA aren't two names for the same number. They're built differently, and using the wrong one against a multiple can make a fair price look like a steal, or a real problem look like a bargain.

Why this mix-up costs buyers real money

Small businesses are priced as a multiple of earnings, so the metric underneath the multiple matters as much as the multiple itself. If a broker's flyer says "priced at 3x cash flow" without saying which cash flow, you can't tell whether the deal is generous or aggressive. A 3x multiple on SDE and a 3x multiple on EBITDA describe two very different businesses, and applying the wrong pairing can move your read on the price by hundreds of thousands of dollars. This is the same discipline as valuing a business you want to buy more broadly: know exactly what number you're multiplying before you trust the multiple. For how the multiple itself moves with deal size, see what's a fair multiple for a small business.

What SDE includes that EBITDA doesn't

SDE is built for the deal most of Scope's readers are looking at: a business small enough that one owner runs it and takes the full benefit (salary, perks, and all) as their income. EBITDA is built for a company that could hand its keys to a hired general manager tomorrow and keep running the same way. What separates the two metrics is that assumption about who runs the business.

A worked example: same business, two numbers

An HVAC company's P&L shows $180K of net profit. Add back the owner's $95K salary, $12K in health insurance, and $18K of depreciation, and you get an SDE of about $305K. At a 3x to 4x SDE screening multiple, that supports an asking price of roughly $915K to $1.22M.

Now run the same financials as EBITDA instead. EBITDA doesn't add back the owner's salary or personal perks, only interest, taxes, depreciation, and amortization. Assuming no debt or corporate tax on this pass-through entity, that leaves EBITDA of about $198K ($180K net profit + $18K depreciation). Applied against the same 3x to 4x range meant for SDE, that reads as a $594K to $792K business. That swing of several hundred thousand dollars on identical financials comes purely from applying an SDE-sized multiple to an EBITDA-sized number. Neither figure is wrong, but they aren't interchangeable, and a multiple only means something once you know which one it was built for.

How do I know which one to use on a deal I'm looking at?

Ask one question: after closing, will you personally run this business day to day, taking the same kind of benefit the current owner does? If yes, price it on SDE, which is step one of analyzing the business correctly. If the business already runs on a management team and the seller is mostly hands-off, EBITDA is the more honest lens. It typically carries a meaningfully higher multiple for the same reason a bigger, more transferable business always does: it's less dependent on any one person, you included.

How do lenders think about SDE vs EBITDA?

For a typical SBA-financed Main Street purchase, the SBA's 7(a) loan program and the lenders underwriting it care about one thing: after you (or a replacement manager) get paid a real salary, is there enough cash flow left to cover the loan payment with room to spare? That's an SDE-style question, and a textbook EBITDA figure won't answer it, even if nobody on the deal ever says the word "SDE" out loud. Run the 60-second lender-math check on a listing before you fall for the story, and see what a 7(a) loan takes to close.

What if the listing already says "EBITDA"?

Don't take the label at face value. Some brokers use "EBITDA" loosely to mean any adjusted-earnings figure, including one that quietly adds back the owner's salary anyway. A figure like that is SDE, whatever the listing calls it. Ask for the add-back schedule and check every line the same way you'd verify any add-back: documentation for each item, cross-checked against the tax returns instead of taken on the broker's word.

FAQ

What's the main difference between SDE and EBITDA?

SDE adds back one working owner's full compensation, because the buyer is expected to step into that role and take the same benefit. EBITDA doesn't add owner pay back. It assumes the business already pays a market-rate manager to run it, whether or not that manager is the owner.

Is SDE or EBITDA a bigger number for the same business?

For an owner-operated business, SDE is almost always the bigger number on the same financials. It includes the owner's full salary and personal add-backs, and EBITDA leaves those out.

Which multiple is higher, SDE or EBITDA?

EBITDA multiples typically run higher than SDE multiples, because EBITDA starts from a smaller base number. A higher multiple on EBITDA doesn't automatically mean a more expensive business. A deal's multiple tells you almost nothing until you check which metric it's applied to.

Do SBA lenders use SDE or EBITDA?

For a typical owner-operated Main Street acquisition, lenders effectively size the loan off SDE-style cash flow: earnings after paying someone (you or a replacement manager) a real salary to run the business. That's the number that has to cover the debt payment.

Can the same business have both an SDE and an EBITDA figure?

Yes. They're two different ways of measuring the same financials, and neither one is an opinion about what the business is worth. A broker's listing might show one, the other, or both. What matters is knowing which one you're looking at before you compare it to a multiple.
