If you’ve started researching what your business might be worth, you’ve probably run into two acronyms that get used almost interchangeably online: SDE and EBITDA. They are not the same thing. Using the wrong one — or the wrong multiple — sets sellers up for unrealistic expectations at the negotiating table.
Here’s the short version: SDE fits owner-operated businesses. EBITDA fits businesses that could run without you. The one that applies to yours shapes your valuation, your buyer pool, and your expected multiple.
SDE starts with your business’s net profit and adds back:
The idea is to show a buyer exactly what the business would generate for one owner-operator working in it full-time — because that’s usually who’s buying it. SDE is the standard valuation method for most Main Street businesses. Think restaurants, laundromats, service businesses, franchises, and most companies sold in the $100,000–$2 million range.
EBITDA makes the same kind of adjustments as SDE, but with one critical difference: it does not add back a market-rate owner’s salary. Instead, it assumes the business already pays a professional manager to run it. That holds whether or not the current owner takes a paycheck.
That distinction matters because acquirers use EBITDA for businesses that already run on a management team — the kind of company a buyer could take over without the founder ever showing up. That’s typically the profile of lower-middle-market businesses and above. It’s also the metric private equity buyers and larger acquirers default to.
SDE assumes a buyer will replace you. EBITDA assumes you’ve already replaced yourself.
If your business can’t run without you in it every day, SDE is almost always the right lens — even if a generic online calculator hands you an EBITDA number instead. If you’ve already built a management layer that could survive your absence, EBITDA is the more accurate measure. It typically supports a materially different multiple, too.
A rough (not exact) rule of thumb we use when scoping a valuation:
This is also where the “business broker vs. M&A advisor” question comes in. Main Street, SDE-valued businesses typically sell through a broker. Larger, EBITDA-valued companies usually move through an M&A process. If you’re not sure which category you’re in, that’s worth figuring out before you set a price expectation.
Say a Fort Myers service business shows $180,000 in net profit on its tax return. Add back a $70,000 owner’s salary, $12,000 in health insurance, a $9,000 personal-use company vehicle, and $6,000 in depreciation. SDE comes out to roughly $277,000. Applying a typical 2.2–2.8x multiple for that industry and size puts the business in the $610,000–$775,000 range.
Run that same $180,000 net profit through an EBITDA lens — no owner-salary add-back — and the number looks completely different. So does the multiple a buyer would apply to it. Same business, same tax return, two very different conversations depending on which method actually fits.
The most common error isn’t picking the wrong method — it’s inconsistent add-backs. That means including a “one-time” expense that actually happens every year. It means adding back a portion of a family member’s salary who genuinely works in the business. Or normalizing rent to market rate without checking whether that cuts both ways. Buyers’ accountants catch this quickly during due diligence. A valuation that doesn’t hold up under scrutiny costs sellers time, leverage, and sometimes the deal itself.
SDE or EBITDA is the starting point of a valuation, not the finish line. The multiple you apply on top of it depends on industry, growth trend, customer concentration, and deal structure.

Is SDE or EBITDA always the higher number?
It depends on the owner’s salary and personal expenses run through the business. There’s no fixed rule — which is exactly why you shouldn’t use the two interchangeably.
Can you value a business both ways?
Yes — especially in the transition zone between Main Street and lower-middle-market. A professional opinion of value will typically show you both if your business is borderline.
Do online valuation calculators use the right method for my business?
Often not — most generic calculators default to one formula regardless of your business’s size or management structure, which is a common source of unrealistic seller expectations.
How much does an owner’s salary add-back actually matter?
Significantly. It’s usually the single largest adjustment in an SDE calculation and the main reason SDE and EBITDA produce different results for the same business.
Should I calculate this myself before talking to a broker?
It’s useful context. But the multiple you apply to either number depends on market data most owners can’t access on their own — that’s where a professional opinion of value adds the most.
