SDE vs EBITDA — if you are thinking about selling your business, understanding the difference between these two valuation metrics is essential. Both measure how much money a business generates for its owner, but they are used in different situations and can produce very different valuation results for the same company.
Choosing the wrong metric — or misunderstanding how each one works — can lead to a business valuation that is tens or even hundreds of thousands of dollars off. This guide explains both metrics in plain language, shows you how to calculate each one, and helps you determine which is right for your business.
What Is SDE (Seller’s Discretionary Earnings)?
Seller’s Discretionary Earnings (SDE) represents the total financial benefit available to a single owner-operator of a business. It answers the question: “How much money does this business put in the owner’s pocket?”
SDE starts with net income and adds back expenses that are discretionary to the owner or that a new owner would not necessarily incur. The goal is to show the true economic benefit of owning and operating the business.
How to Calculate SDE
Start with your net income (bottom line from your income statement), then add back the following:
Owner’s salary and compensation. All wages, bonuses, and payroll taxes paid to the owner. Since the new owner will be the one working in the business, the full owner’s compensation is added back.
Owner’s personal benefits. Health insurance, retirement contributions, auto expenses, personal travel, meals charged to the business, and other perks that benefit the owner personally rather than the business operationally.
Non-recurring expenses. One-time costs that will not repeat under new ownership, such as a lawsuit settlement, a major equipment repair, relocation costs, or the cost of hiring a consultant for a one-time project.
Depreciation and amortization. These are non-cash accounting charges that reduce reported income but do not represent actual cash leaving the business.
Interest expense. Since a new buyer will have their own financing structure, the seller’s interest expense is added back.
Example SDE calculation:
| Net income | $120,000 |
| + Owner’s salary | $150,000 |
| + Owner’s health insurance | $24,000 |
| + Owner’s auto expense | $12,000 |
| + Depreciation | $35,000 |
| + Interest expense | $18,000 |
| + One-time legal settlement | $15,000 |
| SDE | $374,000 |
What Is EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization)?
EBITDA measures the operating profitability of a business independent of its capital structure, tax situation, and accounting decisions. Unlike SDE, EBITDA does not add back the owner’s salary because it assumes the business will need a paid manager or executive to run it after the sale.
EBITDA answers a different question than SDE: “How much operating profit does this business generate, assuming it pays a market-rate manager?”
How to Calculate EBITDA
Start with net income, then add back interest, taxes, depreciation, and amortization. EBITDA does NOT add back the owner’s salary or personal benefits.
Example EBITDA calculation (same business):
| Net income | $120,000 |
| + Depreciation | $35,000 |
| + Interest expense | $18,000 |
| + Income taxes | $40,000 |
| EBITDA | $213,000 |
Notice that the same business has an SDE of $374,000 but an EBITDA of only $213,000. The difference is primarily the owner’s salary and personal benefits ($186,000) that SDE adds back but EBITDA does not, offset by the tax add-back that EBITDA includes.
SDE vs EBITDA: When to Use Each
| Factor | Use SDE | Use EBITDA |
|---|---|---|
| Business size | Under $1M in earnings | $1M+ in earnings |
| Owner involvement | Owner actively works in the business | Business has professional management |
| Typical buyer | Individual buyer / owner-operator | PE firm, strategic acquirer, or financial buyer |
| Purchase price range | Under $5M | $5M+ |
| Financing method | SBA loans, seller financing | Conventional bank debt, PE capital |
| Typical multiple range | 1.5x – 4x SDE | 3x – 8x EBITDA |
The general rule: if the new owner will replace the current owner as a working operator, use SDE. If the business already has (or will hire) a professional manager and the new owner is an investor, use EBITDA.
Why the Metric Matters for Your Valuation
Here is where it gets important. SDE multiples and EBITDA multiples are NOT interchangeable, even though people sometimes confuse them.
Consider our example business with $374,000 in SDE and $213,000 in EBITDA:
| Valuation Method | Multiple | Business Value |
|---|---|---|
| SDE × 2.5x | 2.5x | $935,000 |
| SDE × 3.0x | 3.0x | $1,122,000 |
| EBITDA × 4.0x | 4.0x | $852,000 |
| EBITDA × 5.0x | 5.0x | $1,065,000 |
Using the wrong metric with the wrong multiple could lead you to believe your business is worth significantly more or less than it actually is. A common mistake is applying an EBITDA multiple to an SDE number (or vice versa), which produces a wildly inaccurate result.

Adjusted EBITDA: What Buyers Actually Use
In practice, buyers and their advisors rarely use raw EBITDA. Instead, they calculate “adjusted EBITDA” by adding back non-recurring, non-operational, or discretionary expenses that do not reflect the ongoing economics of the business.
Common adjustments include above-market owner compensation (the portion above what a market-rate replacement would cost), one-time legal or consulting fees, personal expenses run through the business, above-market rent paid to a related party, and non-recurring revenue or expenses.
Adjusted EBITDA falls between raw EBITDA and SDE for most small businesses. It is the most commonly used metric in middle-market transactions and increasingly in larger small business deals.
How to Increase Your SDE or EBITDA Before Selling
Since your business value is a multiple of SDE or EBITDA, every dollar you add to either metric increases your business value by 2-5 times that dollar (depending on your multiple). Here are the most effective ways to increase your earnings metric:
Eliminate unnecessary expenses. Review every line item. Cut subscriptions, tools, and services that do not contribute to revenue or operations. Every $10,000 in unnecessary expenses you eliminate could add $25,000-$50,000 to your business value.
Raise prices. If you have not raised prices in two or more years, you are likely underpricing your services. A 5-10% price increase across your client base flows almost entirely to the bottom line.
Improve gross margins. Negotiate better vendor terms, optimize labor utilization, and reduce waste. Higher margins on the same revenue directly increase your earnings.
Build recurring revenue. Convert one-time projects to retainers, launch maintenance agreements, or add subscription services. Recurring revenue commands higher multiples and increases total earnings.
Document add-backs carefully. Work with your CPA to identify every legitimate add-back. Missed add-backs directly reduce your presented earnings and your valuation. A good broker will also help identify add-backs you may have overlooked.
Frequently Asked Questions: SDE vs EBITDA
Can the same business be valued using both SDE and EBITDA?
Yes. In fact, a good broker will often present both to give buyers a complete picture. However, the multiple applied will differ. An SDE multiple is always lower than the equivalent EBITDA multiple for the same business because SDE is a larger number (it includes the owner’s salary).
Which metric do SBA lenders use?
SBA lenders typically evaluate cash flow using a debt service coverage ratio based on SDE for owner-operated businesses. They want to see that SDE can cover loan payments, a reasonable owner salary, and a margin of safety.
What if I pay myself below market rate?
If your salary is below what a market-rate replacement would cost, this actually hurts your EBITDA (since the business appears more profitable than it would be with properly compensated management). A knowledgeable buyer or broker will adjust for this. Conversely, it does not materially affect SDE since your full salary is added back regardless.
Does SDE include the owner’s spouse on payroll?
If the owner’s spouse is on payroll but does not perform a job that would need to be replaced by a new owner, their salary is typically added back to SDE. If they perform a real function, only the portion above a market-rate replacement salary is added back.
How do I know if my add-backs are legitimate?
A legitimate add-back is an expense that either will not exist under new ownership or is clearly discretionary to the current owner. If a buyer or their accountant would challenge the add-back during due diligence, it is not defensible. Common red flags include adding back expenses that are actually necessary for operations, or adding back the same expense category that appears every year (making it arguably recurring, not discretionary).
