What Is the Difference Between SDE and EBITDA?
Seller Discretionary Earnings (SDE) includes owner compensation and personal expenses that would not continue after a sale. EBITDA excludes those items and reflects profit before interest, taxes, depreciation, and amortization. Buyers use SDE for smaller businesses where the owner is deeply embedded in operations, and EBITDA for larger businesses where management is separate from ownership.
The metric a buyer chooses determines how they see your business. It also determines the multiple they apply, the financing they secure, and the structure they propose.
Most trades business owners do not realize that the line between SDE and EBITDA is not arbitrary. It is a function of size, buyer type, and how replaceable the owner is. When you cross from one metric to the other, the entire valuation conversation shifts.
Why SDE Matters for Smaller Trades Businesses
SDE adds back the owner's salary, health insurance, personal vehicle expenses, family payroll, and other discretionary costs that a new owner would not incur. It reflects the true economic benefit available to a single owner-operator who runs the business themselves.
Buyers of smaller trades businesses, typically under $3 million in revenue, use SDE because they plan to step into the owner's role. They are not hiring a general manager. They are buying a job with equity attached. SDE tells them how much cash the business will generate for them personally after they pay the bills and the crew.
The multiple on SDE is usually lower than the multiple on EBITDA, often between 2.0x and 3.5x for trades businesses in this revenue range. That is not a discount. It reflects the fact that the buyer is replacing the owner's labor, and that labor has value. According to the U.S. Small Business Administration, owner-operators in service businesses often extract 30% to 50% of total profit as direct compensation, which SDE captures but EBITDA does not.
When an HVAC company doing $2 million in revenue shows $150,000 in EBITDA but $300,000 in SDE, the buyer is not confused. They know the owner is taking $150,000 in salary and benefits. They are deciding whether they want to earn $300,000 by running that business themselves.
When Buyers Switch to EBITDA
EBITDA becomes the standard metric when the business no longer requires the owner to operate it day-to-day. That shift typically happens somewhere between $3 million and $10 million in revenue, though the exact threshold depends on the trade, the market, and how the business is structured.
Buyers using EBITDA are not planning to run the business. They are financial buyers, private equity groups, or larger trades companies building a regional platform. They will keep the existing management team or hire a general manager. The owner's salary is not added back because it will be replaced by someone else's salary at market rate.
The multiple on EBITDA is higher than the multiple on SDE, often between 4.0x and 7.0x for trades businesses with consistent earnings and professional management. The increase is not generosity. It reflects the fact that the business can scale without the current owner, which makes it less risky and more financeable.
When a plumbing company doing $8 million in revenue shows $800,000 in EBITDA, and the owner is paid $150,000 as a W-2 employee with a clear role that someone else could fill, that is an EBITDA business. The buyer is buying cash flow that does not depend on one person's presence.
How Buyers Decide Which Metric to Use
Buyers decide which metric to use by asking one question: Can the business operate without the current owner?
If the answer is no, they use SDE. If the answer is yes, they use EBITDA. The decision is not based on revenue alone. A $5 million roofing company where the owner still sells every large job and manages every crew is an SDE business. A $4 million electrical company with a working foreman, a full-time estimator, and a part-time owner is an EBITDA business.
The metric also determines how the buyer finances the deal. SDE-based transactions are typically funded with SBA 7(a) loans, which allow the buyer to finance up to 90% of the purchase price as long as they are stepping into an active management role. EBITDA-based transactions are funded with senior debt, mezzanine financing, or private equity, all of which require the business to generate enough profit to service the debt without relying on the buyer's labor.
When you prepare your business for sale, the first question is not what the business is worth. The first question is which metric a buyer will use. That decision determines the pool of buyers, the structure of the deal, and the price range you should expect.

What Happens When the Metrics Are Mixed
Some businesses fall into a gray area where the owner is partially replaceable but still critical in ways that are hard to quantify. The owner might handle all the estimating but none of the field work. Or they might manage customer relationships but delegate operations to a foreman. These businesses create tension during valuation.
Buyers in this range often calculate both SDE and EBITDA, then discount the business to reflect transition risk. They see the business as too large for a pure owner-operator buyer but too dependent on the current owner for a financial buyer. The result is often a lower multiple, a longer earnout period, or a requirement that the owner stay on for 12 to 24 months post-close.
The solution is not to argue about which metric is correct. The solution is to clarify your role and remove yourself from critical functions before you go to market. If you are the only person who can estimate a job, train someone else. If you are the only person who talks to your top 10 customers, introduce them to your operations manager. If you are the only person who knows how to run the scheduling software, document the process and cross-train your team.
Buyers do not discount businesses because they dislike the owner. They discount businesses because they cannot see how the business works without the owner. When you remove that uncertainty, you move from SDE to EBITDA and from a 3.0x multiple to a 5.5x multiple without changing a single line of your P&L. Understanding what EBITDA is and why it matters becomes essential at this stage.
Why Most Owners Get This Wrong
Most trades business owners do not think about SDE versus EBITDA until they are already in conversations with a buyer. By that point, the metric has already been chosen. The buyer has already decided how to value the business, and the owner is negotiating from a position of confusion rather than clarity.
The mistake is not understanding the definitions. The mistake is not preparing the business to qualify for the metric that commands the higher multiple. Owners assume that revenue growth or profitability improvement will increase value, and they are partially correct. But if the business still cannot operate without the owner, the value ceiling is fixed by the SDE multiple range, no matter how profitable the business becomes.
A $4 million HVAC company doing $600,000 in SDE is worth roughly $1.8 million to $2.1 million to an SDE buyer at a 3.0x to 3.5x multiple. If that same business is restructured so the owner is removable and it shows $450,000 in EBITDA, it is worth $2.25 million to $2.7 million to an EBITDA buyer at a 5.0x to 6.0x multiple, even though the actual cash available to the owner is lower. The difference is buyer pool, financing availability, and perceived risk.
When you build a business that qualifies for EBITDA-based valuation, you are not just increasing the multiple. You are changing the market for your business entirely.
How to Prepare Your Business for the Right Metric
If you want your business to be valued on EBITDA, start by removing yourself from daily operations at least 12 months before you plan to sell. That does not mean you stop working. It means you stop being the only person who can do critical tasks.
Hire or promote a general manager who can run the business without your input for weeks at a time. Formalize your estimating process so someone else can price jobs. Document your vendor relationships and introduce your key contacts to your team. Build a management structure that a buyer can step into without needing you to translate how things work.
If your business is not yet large enough to justify full-time management, focus on cleaning up your SDE calculation. Remove personal expenses that do not belong in the business. Separate your personal vehicle from the company fleet. Stop running family cell phone bills through the P&L. A clean SDE number is easier to defend and easier for a buyer to finance.
Either path works. What does not work is presenting a business that is too large for SDE buyers but too dependent on you for EBITDA buyers. That is the space where deals fall apart or get restructured in ways that leave the owner disappointed.
If you are thinking about selling your trades business in the next 12 to 36 months, the first step is understanding which metric a buyer will use and whether your business is structured to support it.

Frequently Asked Questions
What is the difference between SDE and EBITDA?
SDE (Seller Discretionary Earnings) includes the owner's salary, benefits, and personal expenses that a new owner would not incur. EBITDA excludes those items and reflects profit before interest, taxes, depreciation, and amortization. SDE is used for smaller businesses where the buyer will operate the business themselves. EBITDA is used for larger businesses with professional management.
When do buyers use SDE versus EBITDA?
Buyers use SDE when the business requires the owner to run daily operations, typically for businesses under $3 million in revenue. They use EBITDA when the business can operate without the owner, typically for businesses over $5 million with a management team in place. The decision is based on whether the owner is replaceable, not just revenue size.
Which metric results in a higher business valuation?
EBITDA typically results in higher valuation multiples, often 4.0x to 7.0x for trades businesses, compared to SDE multiples of 2.0x to 3.5x. However, the raw SDE number is usually higher than EBITDA for the same business because it includes owner compensation. The metric that produces the higher absolute value depends on the specific business and buyer type.
Can I switch from SDE to EBITDA valuation before selling?
Yes, by removing yourself from daily operations and building a management team that can run the business without you. This typically requires 12 to 24 months of preparation. You need to delegate critical tasks like estimating, customer management, and crew oversight to employees who will stay after the sale. A business that transitions from SDE to EBITDA valuation often sees a significant increase in enterprise value.
How do I know which metric applies to my trades business?
Ask whether your business can operate for 30 days without your direct involvement in sales, operations, or customer relationships. If the answer is no, buyers will use SDE. If the answer is yes, buyers will use EBITDA. The metric determines buyer type, financing options, and the valuation multiple applied to your earnings.
