When buying or selling a small or medium-sized business (SMB), the right financial metric can make or break the deal. The two most common metrics are SDE (Seller's Discretionary Earnings) and EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization), and they serve different purposes depending on the size and structure of the business.
Key Points:
- SDE includes the owner's salary and discretionary expenses, making it ideal for small, owner-operated businesses (under $3M revenue).
- EBITDA focuses on operational performance, excluding owner-specific adjustments, and is better for larger, professionally managed companies (over $3M revenue).
- Choosing the wrong metric can lead to undervaluation or overvaluation during acquisitions.
Quick Comparison:
| Aspect | SDE | EBITDA |
|---|---|---|
| Definition | Includes owner benefits and discretionary expenses | Excludes owner-specific adjustments |
| Best For | Small, owner-operated businesses | Larger, professionally managed businesses |
| Valuation Multiples | 2-3x SDE | Lower multiples, but on larger revenue |
| Primary Users | Individual buyers, small business brokers | Institutional investors, lenders |
Understanding these metrics ensures accurate valuations and smarter decisions for SMB acquisitions. Keep reading to dive deeper into when and how to use SDE and EBITDA effectively.
SDE vs EBITDA: When to Use Each and How to Calculate Multiples

Understanding SDE
Seller's Discretionary Earnings (SDE) is a key financial metric used to value small businesses, especially those with revenues under $1 million [1]. It represents a business's earnings while accounting for owner-related expenses.
SDE Components
SDE is calculated by combining several financial elements:
- Net Profit: Based on the company's net profit from tax returns.
- Owner's Compensation: Includes the full salary and benefits package.
- Interest Expenses: Covers all interest payments on business debt.
- Depreciation & Amortization: Non-cash deductions from taxable income.
- Discretionary Expenses: Includes non-essential or personal costs.
| Component Type | Examples | Treatment in SDE |
|---|---|---|
| Owner Benefits | Car payments, health insurance, travel | Added back |
| One-time Expenses | Legal fees, equipment purchases | Added back |
| Operating Expenses | Rent, utilities, payroll | Not added back |
| Personal Perks | Memberships, personal phone bills | Added back |
When to Apply SDE
SDE works best in cases where the owner's involvement heavily influences the financial structure of the business.
Common Scenarios:
- Businesses generating less than $3 million in annual revenue [2].
- Owner-operated businesses where compensation is a major expense.
- Companies with overlapping personal and business expenses.
- Small retail or service businesses with heavy owner involvement.
For instance, consider a small retail business earning $800,000 annually. If the owner takes a salary of $120,000, spends $15,000 on vehicle expenses, and $10,000 on discretionary travel, these adjustments provide a clearer picture of the business's earning potential [2].
SDE combines profits and owner-related expenses into a single figure, showing the total earnings available to a new owner. Typically, businesses are valued at 2-3 times their SDE. For example, an SDE of $200,000 could result in a valuation of $400,000 to $600,000, depending on industry standards [1].
While SDE is great for small, owner-operated businesses, larger companies often rely on a different metric: EBITDA.
Understanding EBITDA
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It's a key figure used to assess a company's operational profitability, especially for larger businesses. Unlike SDE (Seller's Discretionary Earnings), EBITDA focuses solely on operational performance, leaving out any owner-specific adjustments. This makes it a better fit for evaluating larger companies.
Breaking Down EBITDA
Here's a quick look at the key components of EBITDA and why certain items are excluded:
| Component | Description | Why It's Excluded |
|---|---|---|
| Interest | Financing costs and debt payments | Tied to financing, not operations |
| Taxes | Federal, state, and local taxes | Varies by location and structure |
| Depreciation | Reduction in asset value over time | Non-cash expense |
| Amortization | Allocation of intangible asset costs | Non-cash expense |
For example, if a company has an operating profit of $524,650 and adjustments totaling $70,500, its EBITDA would be $595,150 [1].
When Should You Use EBITDA?
EBITDA is best suited for businesses that meet the following criteria:
- Generate more than $3 million in annual revenue
- Have a professional management team in place
- Aren't heavily influenced by owner compensation
- Are looking for institutional investors or bank loans
This metric is especially useful for lenders, as it shows a company's ability to handle debt. However, it's important to note that EBITDA doesn't account for capital expenditures, which can hide long-term operational needs [3]. For this reason, M&A advisors and investment bankers often rely on EBITDA when valuing mid-sized companies.

Comparing SDE and EBITDA
Now that we've broken down these metrics individually, let’s dive into their differences and how they influence business valuations. The choice between SDE and EBITDA isn’t just a matter of preference - it shapes how buyers and sellers perceive a business's worth.
SDE vs EBITDA Table
| Aspect | SDE (Seller's Discretionary Earnings) | EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) |
|---|---|---|
| Definition | Includes owner's benefits and discretionary expenses | Excludes owner benefits; focuses on core operational earnings |
| Owner's Compensation | Added back into earnings calculation | Excluded from the calculation |
| Best Fit For | Small, owner-operated businesses | Larger, professionally managed companies |
| Typical Business Size | Businesses earning under $1M | Companies generating over $1M in earnings |
| Management Structure | Single owner-operator | Managed by a professional team |
| Primary Users | Individual buyers, small business brokers | Institutional investors, investment bankers |
| Financing Focus | Individual buyer loans | Institutional lending or bank loans |
How Valuation Multiples Differ
The metric you choose - SDE or EBITDA - has a direct impact on valuation during acquisition discussions:
-
SDE Valuations: SDE-based valuations often result in higher multiples. For instance, a small retail business with $300,000 in earnings might sell for 2.5x to 3.5x the SDE figure [1]. This is because SDE includes the owner’s compensation, making the business appear more profitable to buyers focused on smaller, owner-operated enterprises.
-
EBITDA Valuations: EBITDA typically applies lower multiples but is calculated on larger revenue figures. This metric is favored for businesses run by professional management, as it highlights operational performance without factoring in owner-specific benefits [2].
-
Industry Practices: The choice between SDE and EBITDA often depends on industry norms. For example, SDE valuations include the full owner’s salary, while EBITDA adjustments only account for compensation above market rates. This difference can have a major impact on how businesses in specific sectors are valued [2].
The right metric depends on factors like company size, management structure, industry expectations, and the type of buyer involved. Both metrics serve different purposes, but understanding their nuances ensures you’re prepared for negotiations and can align your valuation approach with your business strategy.
Applying SDE and EBITDA in Acquisitions
Industry Considerations
The decision to use SDE (Seller's Discretionary Earnings) or EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) depends heavily on the industry, as it directly influences valuation methods. For service-oriented businesses like consulting firms or professional practices, SDE is often the better choice since the owner's compensation forms a large part of the operating costs. For instance, in a dental practice, the dentist-owner's salary is a key factor, making SDE calculations more relevant.
On the other hand, industries like manufacturing and distribution lean towards EBITDA. These businesses typically involve more complex operations where owner compensation is a smaller piece of the puzzle compared to other factors like equipment, inventory, and workforce expenses.
| Industry Type | Preferred Metric | Key Consideration |
|---|---|---|
| Small, Owner-Operated Businesses | SDE | High owner involvement |
| Manufacturing/Distribution | EBITDA | Complex operational structure |
| Technology | EBITDA | Focus on scalable operations |
While industry norms are a helpful guide, buyers should remain vigilant for any financial irregularities that could skew the valuation.
Financial Red Flags
Identifying financial red flags is essential, whether you're working with SDE or EBITDA, to ensure the valuation reflects the business's true performance.
SDE Red Flags:
- Personal expenses mixed into business costs
- Irregularities in owner compensation
- Undocumented cash transactions
EBITDA Red Flags:
- Unrealistic adjustments to management salaries
- Missing documentation for operational adjustments
When conducting due diligence, review at least three years of financial records to normalize the data. This helps uncover patterns and ensures adjustments are grounded in reality, not inflated earnings.
For businesses with annual sales under $1 million, pay close attention to SDE calculations, especially the owner's compensation and benefits. For larger businesses using EBITDA, focus on how management salaries have been adjusted.
Partnering with financial advisors who specialize in these areas can help avoid costly valuation errors and provide a clearer picture of the business's true worth.
Conclusion
Deciding between SDE and EBITDA as a valuation metric can play a key role in determining the success of an acquisition. The choice depends on how these metrics align with the specific context of the business and its valuation needs.
Key Takeaways
The size and structure of a business largely dictate whether SDE or EBITDA is the better fit. Smaller, owner-operated businesses typically align with SDE, while larger companies with professional management are better suited to EBITDA. Industry practices and the complexity of a company’s operations also shape this decision.
Here are the three main factors to consider when choosing a metric:
- Business Structure: How involved the owner is and how compensation is handled.
- Industry Standards: Common valuation expectations within the sector.
- Financial Complexity: The level of operational and accounting sophistication.
Understanding these elements, along with recognizing industry norms and spotting financial red flags, is essential. This knowledge helps buyers avoid pitfalls and make informed decisions during the acquisition process.
