The metric determines the deal. According to the IBBA Q4 2025 Market Pulse, U.S. business brokers use Seller's Discretionary Earnings for any business priced below $2 million and switch to EBITDA for deals ranging from $2 million to $50 million. Two buyers looking at the same company can arrive at valuations that differ by more than $1 million simply by choosing the wrong earnings metric. This is not a technicality. It drives the multiple. It drives the offer.
Every search fund operator and ETA buyer needs to understand this distinction before building a single model.
What SDE actually measures
SDE stands for Seller's Discretionary Earnings. The calculation:
Net income + owner salary + owner benefits + interest + taxes + depreciation + amortization + one-time or non-recurring expenses = SDE
SDE answers one question: how much cash does this business produce for a single owner-operator who works in it full-time? That owner might draw a $200,000 salary, run personal health insurance through the business, and expense a company vehicle. SDE adds it all back. The metric assumes the buyer replaces the seller — same role, same hours, same seat.
It is the right metric for Main Street businesses where the owner is the business. Remove the owner and you remove the operation.
What EBITDA actually measures
EBITDA: Earnings Before Interest, Taxes, Depreciation, and Amortization.
Net income + interest + taxes + depreciation + amortization = EBITDA
EBITDA excludes owner compensation. Not because management is free, but because the metric assumes professional management has already been hired or will be hired at market rate. You buy the business. You install a CEO or general manager to run it. That manager's salary is a real operating expense. EBITDA bakes in that cost by not adding owner comp back in the first place.
Same business. Different assumption about who runs it. Different number.
The structural difference in one example
Take a $5 million revenue distribution company. The owner draws a $300,000 salary and works 50 hours a week running operations.
- EBITDA: $700,000
- SDE: $700,000 + $300,000 owner comp = $1,000,000
Now apply market multiples from the IBBA Q4 2025 data:
- SDE businesses: 2-4x. At 3x: $3,000,000 valuation
- EBITDA businesses: 4-9x. At 6x: $4,200,000 valuation
Same business. $1.2 million gap. Both numbers are defensible depending on buyer type and deal structure. The gap is real and it widens as business size increases.
Where the cutoff actually sits
IBBA confirms the demarcation precisely:
- Purchase price below $2 million: value on SDE
- Purchase price $2 million to $50 million: value on EBITDA
In earnings terms, this translates to roughly:
- Under $1 million to $1.5 million in owner earnings: SDE territory
- Above $1 million to $2 million in owner earnings: EBITDA territory
Search fund targets typically sit in the $1 million to $4 million EBITDA band. That is the zone where the metric question is most acute. A business generating $900,000 of owner earnings is priced on SDE. One generating $1.3 million may be caught at the transition — and how the broker frames it will determine whether you are competing against Main Street buyers or institutional ETA capital.

Current multiples by deal tier
IBBA Q4 2025 and Q3 2025 Market Pulse data show median multiples across deal sizes:
| Purchase Price | Metric Used | Median Multiple |
|---|---|---|
| Under $500K | SDE | ~2.3x |
| $500K to $1M | SDE | ~3.0x |
| $1M to $2M | SDE | ~3.5x |
| $2M to $5M | EBITDA | ~4.5x |
| $5M to $50M | EBITDA | ~5.5x |

Why this matters for your offer
Model the wrong metric and the deal breaks before it starts.
Scenario 1: You overpay by treating an SDE business as EBITDA-priced.
A $4 million revenue company shows $700,000 EBITDA and $400,000 owner comp. True SDE is $1,100,000. You model at 5x EBITDA and offer $3.5 million. The seller says no. His broker ran SDE. At 3x SDE, the implied clearing price is $3.3 million. The deal died because of metric mismatch, not negotiation.
Scenario 2: You underprice an EBITDA business using SDE.
A $10 million revenue services business generates $2.5 million EBITDA. Owner comp is $350,000. SDE is $2.85 million. You model 3x SDE and offer $8.55 million. The market prices this at 5-6x EBITDA, or $12.5 to $15 million. You are $4 million short of the clearing price. You will not see this deal again.
The SDE-to-EBITDA conversion trap
Sellers near the $1 million to $2 million earnings threshold try to arbitrage both metrics. Watch for this in Confidential Information Memorandums. A CIM showing $1.2 million SDE might argue for a 5x multiple because "comparable EBITDA transactions" support it. The problem: $1.2 million SDE converts to roughly $900,000 EBITDA after subtracting $300,000 for a market-rate replacement manager. That $900,000 EBITDA at 5x is $4.5 million. The seller's implied ask using SDE at 5x is $6 million. The $1.5 million gap is the conversion trap.
Always convert SDE to EBITDA before applying any LMM multiple. The formula: subtract market-rate owner replacement compensation from SDE. Apply the resulting EBITDA the correct segment multiple. For more detail, see our breakdown of how seller's discretionary earnings work.
What this means for sellers
Patriot Growth Capital works with sellers preparing exits. The SDE versus EBITDA question matters from the sell-side too.
If your business generates $800,000 in owner earnings, you are priced on SDE. Your buyer pool is individual operators, SBA borrowers, and local acquirers. That pool is large but price-sensitive.
If you grow to $1.2 million or $1.5 million in earnings, you cross into a valuation framework that institutional search funds, ETA sponsors, and lower-middle-market PE can access. The same dollar of EBITDA growth that moves you from $900,000 to $1.1 million changes your buyer universe. That shift typically drives a higher multiple even before accounting for the earnings increase itself.
Growth is not just revenue. At a certain threshold, it changes the metric used to price the exit.
The pre-offer checklist
Before building any acquisition model:
- Get the trailing twelve months P&L and the seller's disclosed compensation package
- Build SDE: net income + owner comp + benefits + non-recurring add-backs
- Build EBITDA: net income + interest + taxes + D&A, no owner comp added back
- Determine which market segment you are in based on earnings level
- Apply the correct metric and the IBBA-supported multiple for that segment
- If you are between $800,000 and $1.5 million SDE, model both and understand the seller's likely framing
The metric is not arbitrary. It reflects a structural difference in how the business operates and who will run it after closing. Get that right first. Everything else follows.
Frequently Asked Questions
What is the main difference between SDE and EBITDA when buying a business?
SDE adds back the owner's salary, benefits, and perks on top of standard EBITDA adjustments. EBITDA does not. SDE assumes the buyer fills the owner's seat directly. EBITDA assumes a market-rate manager will be hired to run the business. The same business will show a higher SDE than EBITDA by the amount of owner compensation that gets added back.
At what earnings level should a buyer switch from SDE to EBITDA?
The IBBA Market Pulse places the break at a purchase price of $2 million. In earnings terms, businesses generating under $1 million to $1.5 million in owner earnings are typically priced on SDE. Those generating above $1.5 million to $2 million cross into EBITDA territory where institutional buyers and search fund capital compete.
Why do EBITDA businesses command higher multiples than SDE businesses?
EBITDA businesses are larger, have professional or installable management, and carry less key-person risk. They are more bankable, more scalable, and accessible to institutional capital. SDE businesses depend on one operator's direct involvement, which compresses the buyer pool and the multiple. The metric reflects underlying business quality, not just accounting convention.
Can a seller use SDE multiples on a business that should be priced on EBITDA?
Sellers near the transition zone often present both metrics to maximize perceived value. Buyers should always convert SDE to EBITDA by subtracting a market-rate replacement manager's compensation before applying any multiple. A CIM that applies EBITDA multiples to SDE figures without that conversion is inflating the implied price. Catch it in diligence before signing an LOI.
