SDE vs. EBITDA: Which Earnings Metric Matters for Your Business?

Two buyers look at the same dry cleaner. One sees $420,000 in earnings. The other sees $240,000. Neither is wrong. They are using different metrics — and the metric you choose quietly determines everything that follows.

This is the SDE vs. EBITDA question, and it sits at the center of almost every small and lower-middle-market transaction. Get it wrong and you will argue about valuation for months. Get it right and the number falls out of the financials in a morning.

What SDE actually measures

SDE stands for Seller's Discretionary Earnings. It is the total financial benefit a single working owner extracts from a business in a year. Think of it as "what the owner's seat is worth" rather than "what the company earned."

The math starts with net income and then adds back everything that belongs to the seller's personal situation rather than the ongoing operation:

• The owner's W-2 salary
• The owner's payroll taxes and benefits
• Personal expenses run through the business (vehicle, phone, meals, travel, family members on payroll who do not actually work)
• Interest expense
• Depreciation and amortization
• Non-recurring items (a one-time legal settlement, a failed expansion, PPP forgiveness)

What you are left with is the full economic return a new owner-operator would inherit if they stepped into the seat and ran the business exactly as it runs today.

SDE assumes one owner. That is the critical point. If a business has two working owners, each drawing compensation, only one salary is added back. The other owner's compensation stays as a business expense because any buyer will need to replace that role.

What EBITDA actually measures

EBITDA — earnings before interest, taxes, depreciation, and amortization — measures the cash earnings of the business as a business, independent of who owns it. It assumes an arms-length management team earning market wages.

The add-backs are narrower than SDE. You add back:

• Interest (because it depends on capital structure)
• Taxes (because they depend on entity type)
• Depreciation and amortization (because they are non-cash)
• Truly non-recurring items

You do not add back the owner's salary. If the owner pays themselves $80,000 but a market-rate CEO for that business would cost $180,000, you subtract an additional $100,000 from EBITDA as an owner's compensation adjustment. This produces what institutional buyers call adjusted EBITDA — EBITDA normalized to market management costs.

That normalization is why EBITDA is lower. SDE treats the owner as a source of earnings. EBITDA treats the owner as a cost of doing business.

The same company, two numbers

Take a small HVAC contractor:

• Revenue: $2.4M
• Net income: $180,000
• Owner's W-2 salary: $140,000
• Payroll taxes and benefits on owner: $22,000
• Personal vehicle and cell phone: $14,000
• Interest expense: $18,000
• Depreciation: $46,000
• One-time roof replacement on the shop: $30,000

SDE calculation: 180 + 140 + 22 + 14 + 18 + 46 + 30 = $450,000.

EBITDA calculation: 180 + 18 + 46 + 30 = $274,000. Then subtract the owner compensation adjustment. A market-rate GM for a $2.4M HVAC shop runs about $130,000 all-in. Owner currently costs $162,000 (salary plus taxes plus benefits). So adjusted EBITDA gets a positive adjustment of $32,000, landing at $306,000.

Same business. $450,000 under SDE. $306,000 under adjusted EBITDA. Both are defensible. Both describe something real.

Which one the market uses

SDE dominates transactions under about $3 million in enterprise value. This is the classic owner-operator territory — HVAC, landscaping, auto repair, niche retail, specialty manufacturing with one working owner. Buyers in this tier are almost always individuals using SBA 7(a) loans, and their underwriters are comfortable with SDE multiples.

Typical SDE multiples land in a 2.0x to 3.5x range depending on industry, recurring revenue, and size, with some asset-heavy or sticky-customer businesses pushing higher.

EBITDA takes over somewhere between $3M and $5M in enterprise value. Above that line, buyers are usually private equity firms, family offices, or strategic acquirers. These buyers install professional management. They price the business on what it will earn under that management, not what the current owner extracts from it.

Typical EBITDA multiples in the lower middle market run 4x to 7x for profitable, clean businesses, with higher ranges for software, healthcare services, and consolidation plays.

The overlap zone — roughly $3M to $5M in enterprise value, or $500K to $900K in owner benefit — is where buyers will look at both numbers and often argue about which applies. A sophisticated seller in that zone should be able to produce both.

Why lenders care

SBA lenders have a specific interest in SDE. SBA 7(a) underwriting cares whether a single working owner can service the debt and still pay themselves a reasonable living. The lender's debt service coverage calculation runs off SDE minus a living wage for the new owner, divided by the new debt payments. If that ratio is below 1.25x, the loan does not close regardless of the asking price.

This means two things for owners. First, the SDE number has to be documentable — lenders will not accept claimed add-backs without support. Second, the structure of the deal (price, down payment, seller financing) has to produce a clearing debt service ratio, which is why the price the buyer can afford is often capped by the financing math rather than the multiple.

Institutional lenders — commercial banks funding private equity buyouts — do the same exercise with EBITDA, not SDE. The test is fixed charge coverage or debt service coverage on the normalized cash flow after market management is in place.

Why the wrong metric hurts the seller

Sellers lose money in two predictable ways when the metric is misapplied.

The first is applying an SDE multiple to an EBITDA number. A broker tells the owner of a $2M EBITDA company that "businesses trade at 3x," which would be true on SDE but is a 40% haircut on EBITDA. The listing goes up at $6M when the right number is closer to $10M.

The second is the reverse — applying an EBITDA multiple to an SDE number. A valuation consultant uses 6x "because that's where the market is," on a business with $400K of SDE, and produces a $2.4M number. A real buyer looks at the $400K, recognizes it as SDE because there is only one working owner, and offers $1.0M to $1.2M. The seller is insulted, the deal dies, and both sides waste three months.

Matching the multiple to the metric matters more than picking which metric to use.

Recasting is where the arguments happen

Both SDE and EBITDA depend on the same underlying move: recasting the financials. Recasting means rebuilding the income statement around the economic reality of the business rather than the tax reality. Owners run expenses through the business to minimize taxable income. That is rational while you own it and expensive when you try to sell it.

Careful recasting — with documentation — routinely uncovers 15% to 40% more earnings than the tax return shows. Sloppy recasting gets laughed out of diligence. The difference is whether you can produce receipts, vendor statements, or bank records tying each add-back to a specific transaction.

When you are preparing for sale, do the recasting first. The valuation flows from it. The multiple is almost beside the point until the earnings number is defensible.

How VEMLogic handles both

VEMLogic reports present both SDE and EBITDA on every valuation where both apply. The recasting worksheet documents every add-back line by line, and the market multiple section cites comparable transactions at both metrics so buyers and lenders can verify the reasoning. For owner-operated businesses under $3M in value, SDE leads; for larger businesses, adjusted EBITDA leads. Either way, the full picture is in the report, not hidden behind a single number.
