When it comes to valuing a small business, two acronyms dominate the conversation: SDE and EBITDA. Both measure profitability. Both are used to set sale prices. But they are not the same, and using the wrong one can dramatically understate or overstate what your business is worth.
If you are preparing to sell, negotiating with a buyer, or just trying to understand what multiple your business should command, getting clear on the SDE vs EBITDA distinction is non-negotiable. Here is the plain-English explanation that most business owners never get.
What Is SDE?
SDE stands for Seller’s Discretionary Earnings. It is designed to answer one specific question: how much money does this business put in the owner’s pocket each year?
To calculate SDE, you start with the business’s pre-tax net income and add back:
- The owner’s salary (or draw)
- Personal expenses the owner runs through the business (health insurance, car, phone, etc.)
- Depreciation and amortization
- Interest expense
- One-time or non-recurring expenses
The idea is to strip out every cost that is unique to the current owner and show a clean picture of the business’s earning power for a new owner-operator who would step into the role.
Example: Your plumbing business shows $80,000 in net income on the tax return. But you pay yourself $95,000 in salary, your truck runs through the business at $12,000 per year, and you had a one-time equipment repair of $8,000. Add those back: $80,000 + $95,000 + $12,000 + $8,000 = $195,000 SDE. That is a very different number than the bottom line on your P&L.
What Is EBITDA?
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It is the standard profitability metric used in corporate finance, private equity, and mid-market business transactions.
The key difference from SDE: EBITDA does NOT add back the owner’s salary. The assumption is that a buyer will hire someone to run the business (a general manager or CEO), and that cost needs to stay in the equation because it is a real operating expense.
EBITDA formula: Net Income + Interest + Taxes + Depreciation + Amortization = EBITDA
Using the same plumbing example: if you replace your $95,000 salary with a $75,000 general manager salary (market rate), and the business was otherwise generating $80,000 net income plus $20,000 in D&A and interest, your EBITDA might be around $175,000. The salary stays in; only the financing and non-cash charges come out.

SDE vs EBITDA: Side-by-Side Comparison
| SDE | EBITDA | |
|---|---|---|
| Adds back owner’s salary? | Yes | No |
| Typical business size | Under $5M revenue | $2M+ revenue |
| Buyer assumption | New owner will operate the business | Owner will hire a manager to run it |
| Typical multiple range | 2x – 4x SDE | 3x – 10x+ EBITDA |
| Used by | Business brokers, main street buyers | Private equity, investment bankers, institutional buyers |
| Personal expenses added back? | Yes | Generally no |
Which Method Is Right for Your Business?
The short answer: it depends on who is buying and how they plan to operate the business after the sale.
Use SDE When…
Your business generates less than $5 million in annual revenue and is run by an owner-operator. The likely buyer is an individual who will replace you in the business and pay themselves from the earnings. Main street businesses: local service companies, retail shops, restaurants, small professional practices, franchises. Business brokers universally use SDE for these deals because it answers the question a buyer actually cares about: “What can I take home if I buy this?”
SDE is also more forgiving of owner perks. The buyer does not care that you drove a company truck or took health insurance through the business. Those costs belong to whoever owns the business. SDE normalizes all of that.
Use EBITDA When…
Your business is larger, has a management team already in place, or is likely to be acquired by a private equity firm, strategic buyer, or institutional investor. These buyers are not buying a job; they are buying a cash-flowing asset. They will bring their own management or layer it into a larger platform. The owner’s compensation is irrelevant to them because you will be gone.
EBITDA becomes the right metric roughly when revenue exceeds $2-3 million and there is actual infrastructure beyond the founder. If you have a CFO, operations manager, or sales team, buyers will think in EBITDA terms. This is also the metric that connects to private equity deal structures and lender underwriting for acquisition loans. The IRS guidance on selling a business covers how different sale structures affect your tax treatment, which is also connected to how the purchase price is allocated.
Why the Distinction Matters for Your Sale Price
The method you use does not just change the calculation. It changes the entire framing of the deal and which buyers you attract.
Imagine a business with $400,000 in EBITDA and an owner who pays himself $120,000. The SDE is $520,000. At a 3x SDE multiple, the business is worth $1.56 million. At a 4x EBITDA multiple (with a $90,000 management salary baked in), it is $400,000 x 4 = $1.6 million. In this case they land near the same place. But in many scenarios they diverge sharply, and understanding which lens a buyer will use determines your negotiating position.
The other thing that matters: multiples are applied differently. SDE multiples tend to run lower (2-4x) because the buyer is also buying a full-time job. EBITDA multiples run higher (4-10x) because the buyer is getting a truly passive or semi-passive investment. A higher EBITDA multiple on a smaller earnings base can actually be worth less in real dollars than a lower SDE multiple on a larger add-back number. Do the actual math with both methods before settling on what you think your business is worth.
Getting the Numbers Right
Whether you use SDE or EBITDA, the most important step is the same: prepare a clean, itemized recasting of your financials (often called a Recast P&L or Adjusted Income Statement) that shows exactly what you are adding back and why. Every add-back needs documentation. A buyer or their accountant will verify all of it during due diligence.
Undocumented add-backs get challenged. Challenged add-backs get removed. Removed add-backs reduce your sale price. The discipline of documenting your business pays off directly in dollars at closing.
Work with a certified business broker or M&A advisor early. They will tell you which method the likely buyers for your business will use, what add-backs are defensible, and how to position the financials to maximize your sale price.
