SDE vs EBITDA: Which Earnings Metric for Your Business Valuation?
SDE (seller's discretionary earnings) includes the owner's full compensation as an add-back, making it the standard earnings metric for owner-operated businesses under $5 million in revenue. EBITDA excludes owner compensation and measures operational profitability, making it the preferred metric for larger businesses with professional management. The choice between SDE and EBITDA directly affects which valuation multiples apply and how buyers, brokers, and lenders evaluate a business.
Key Takeaway
This guide covers everything you need to know about sde vs ebitda: which metric to use for business valuation, from fundamental concepts to practical application. Whether you are a business owner, buyer, or advisor, the frameworks and methods explained here will help you make informed decisions backed by data.
SDE (seller's discretionary earnings) and EBITDA (earnings before interest, taxes, depreciation, and amortization)are the two primary earnings metrics used to value private businesses. SDE includes the owner's total compensation as an add-back, making it the standard for owner-operated businesses under $5 million in revenue. EBITDA excludes owner compensation and measures operational profitability independent of ownership, making it the preferred metric for larger businesses with professional management teams. Choosing the wrong metric applies the wrong set of multiples and can misrepresent business value by 20-40%.
What Is SDE (Seller's Discretionary Earnings)?
Seller's discretionary earnings is the total pre-tax economic benefit that a single full-time owner-operator derives from a business in one year. SDE is calculated by starting with net income and adding back the owner's salary, personal benefits charged to the business, non-cash expenses (depreciation and amortization), interest on business debt, and any one-time or non-recurring expenses.
SDE Formula
SDE = Net Income + Owner's Compensation + Owner's Perks + Depreciation & Amortization + Interest Expense + Non-Recurring Expenses
Example: A landscaping company reports $80,000 in net income. The owner takes a $110,000 salary, has $15,000 in personal vehicle expenses charged to the business, $12,000 in depreciation, $8,000 in interest, and a $10,000 one-time equipment repair. SDE = $80,000 + $110,000 + $15,000 + $12,000 + $8,000 + $10,000 = $235,000.
The reason SDE adds back the owner's entire compensation is that the buyer of a small business is typically purchasing a job along with a business. The buyer will replace the current owner and draw whatever compensation the business can support. By measuring the total economic benefit, not just profit after the current owner's salary, SDE gives buyers a complete picture of the cash flow available to them.
What Is EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization)?
EBITDA measures the operational profitability of a business before accounting for capital structure (interest), tax jurisdiction (taxes), and non-cash accounting charges (depreciation and amortization). Unlike SDE, EBITDA does not add back the owner's compensation. It assumes a market-rate manager runs the business and that manager's salary is an operating expense.
EBITDA Formula
EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization
Example: A digital marketing agency reports $180,000 in net income, $5,000 in interest, $45,000 in taxes, $8,000 in depreciation, and $3,000 in amortization. EBITDA = $180,000 + $5,000 + $45,000 + $8,000 + $3,000 = $241,000.
EBITDA is the standard earnings metric in mid-market M&A (businesses valued above $2-3 million) because it normalizes for financing and tax differences between companies, making direct comparisons possible. Private equity firms, strategic acquirers, and investment bankers all communicate in EBITDA multiples. When a buyer says they will pay “5x EBITDA,” they mean five times the normalized EBITDA, adjusted for any above-market or below-market expenses.
SDE vs EBITDA: Key Differences
| Factor | SDE | EBITDA |
|---|---|---|
| Owner compensation | Added back (included in SDE) | Treated as operating expense |
| Owner perks and benefits | Added back | Not added back (or normalized to market rate) |
| Business size | Under $5M revenue / under $1M SDE | $5M+ revenue / $1M+ EBITDA |
| Typical buyer | Owner-operator | Private equity, strategic acquirer |
| Multiple range | 1.5x-4.0x | 3x-12x+ |
| SBA loan underwriting | Primary metric for debt coverage | Used for larger acquisitions |
| Management assumption | Owner works full-time in the business | Professional manager runs operations |
| Comparability | Normalizes for one owner's lifestyle | Normalizes across all ownership structures |
When to Use SDE vs EBITDA
Use SDE When...
- ✓The business has annual revenue under $5 million
- ✓The owner works full-time in the business
- ✓The most likely buyer is another owner-operator
- ✓The business is being sold through a business broker
- ✓SBA financing is anticipated for the acquisition
- ✓The owner's compensation is a significant portion of the business's cash flow
Use EBITDA When...
- ✓The business has annual revenue above $5 million
- ✓A management team operates the business day-to-day
- ✓The likely buyer is a private equity firm or strategic acquirer
- ✓An investment banker or M&A advisor is running the process
- ✓You are comparing against public company benchmarks
- ✓The business has multiple owners with defined roles
How to Convert SDE to EBITDA (and Vice Versa)
Since many owners calculate SDE first but need EBITDA for comparison with larger-company benchmarks, the conversion is straightforward: subtract the market-rate cost of a replacement manager from the SDE to get EBITDA.
Conversion Formulas
EBITDA = SDE - Market-Rate Manager Salary
SDE = EBITDA + Owner's Actual Compensation + Owner's Perks
Example: An HVAC company has SDE of $380,000. A qualified general manager in this market costs $120,000. Therefore, EBITDA is approximately $380,000 - $120,000 = $260,000. At a 2.8x SDE multiple, the value is $1,064,000. At a 4.0x EBITDA multiple, the value is $1,040,000, a consistent result that validates both approaches.
The key variable in this conversion is the manager's replacement salary. Use actual job postings and salary surveys for your industry and geography, not a generic estimate. Overstating the manager's salary understates EBITDA and vice versa, which flows directly into the valuation.
SDE vs EBITDA by Industry: Practical Examples
The choice between SDE and EBITDA is not always clear-cut. Here are practical examples from different industries showing how the metric choice affects the valuation conversation.
Restaurant (Full Service): Use SDE
A family-owned restaurant generating $1.2 million in revenue with the owner serving as head chef and general manager. The owner takes $85,000 in salary plus $30,000 in personal benefits. Because the buyer will likely replace the owner in the kitchen and in management, SDE captures the full economic benefit. With an SDE of $250,000 and a restaurant industry median multiple of 2.5x, the estimated value is $625,000.
IT Services / MSP: Use EBITDA
An IT managed services provider with $8 million in recurring revenue, 45 employees, and a professional management team. The founder serves as CEO but handles strategy, not daily operations. EBITDA is the correct metric because a buyer (likely a PE-backed MSP platform) will retain the management team. With $1.2 million in EBITDA and a 7x multiple, the estimated value is $8.4 million.
Dental Practice: Could Use Either
A dental practice with $2 million in revenue sits in the gray zone. If the dentist-owner plans to sell to another solo practitioner, SDE is the right metric. If a dental support organization (DSO) is the likely buyer, and they will employ the dentist or replace them, EBITDA becomes more relevant. Preparing both metrics allows the seller to market the practice to both buyer types.

Frequently Asked Questions
Can a business use both SDE and EBITDA in a valuation?
Yes. Many professional valuations calculate both SDE and EBITDA to provide different perspectives on value. The SDE-based valuation shows what the business is worth to an owner-operator, while the EBITDA-based valuation shows what it is worth to a buyer who will hire a manager. Presenting both metrics helps sellers understand the range of possible outcomes depending on the buyer profile.
Why are EBITDA multiples higher than SDE multiples?
EBITDA multiples are higher than SDE multiples because EBITDA is a smaller number because it does not include the owner's compensation as an add-back. Since the buyer must pay a manager's salary out of EBITDA, the resulting valuation from both methods should produce a similar total business value. For example, a business with $400,000 SDE and a 2.5x SDE multiple is worth $1,000,000, roughly the same as $200,000 EBITDA at a 5.0x EBITDA multiple.
At what revenue level should I switch from SDE to EBITDA?
The general threshold is $5 million in annual revenue or $1 million in SDE. Below that, most buyers are owner-operators who will work in the business, making SDE the relevant metric. Above that, buyers are increasingly private equity firms or strategic acquirers who will install professional management, making EBITDA the standard. The transition zone between $3 million and $10 million in revenue may warrant calculating both.
How do I convert SDE to EBITDA?
To convert SDE to EBITDA, subtract a reasonable manager's replacement salary from the SDE. The formula is: EBITDA = SDE - Market-Rate Manager Salary. For example, if the SDE is $400,000 and a full-time general manager in your industry costs $120,000, the EBITDA is approximately $280,000. The manager salary should reflect the actual market rate for someone who could operate the business day-to-day without the owner.
Do SBA lenders use SDE or EBITDA for loan underwriting?
SBA lenders typically use SDE for smaller acquisitions (under $5 million) because it represents the total cash flow available to service debt and pay the owner. The lender calculates a debt service coverage ratio (DSCR) by dividing SDE by the annual loan payments. Most SBA lenders require a DSCR of at least 1.25:1, meaning the SDE must be at least 25% higher than the annual debt service.
