If you are thinking about selling your business, you have likely encountered two acronyms that come up in nearly every valuation conversation: SDE and EBITDA. Both are measures of a business's earning power, but they serve different purposes, apply to different types of businesses, and can produce very different numbers from the same financial statements.

Understanding which metric buyers will apply to your business, and how to calculate it correctly, is one of the most important steps in preparing for a successful sale. This guide breaks down both metrics in plain language, explains when each one is used, and highlights the common mistakes that can cost sellers significant value.

What You'll Learn

What Is SDE (Seller's Discretionary Earnings)?

SDE represents the total financial benefit a single owner-operator derives from the business. It starts with net income and adds back the owner's salary, benefits, and personal expenses, along with interest, taxes, depreciation, amortization, and any non-recurring or discretionary expenses.

The logic behind SDE is straightforward: if a new owner steps into the business and replaces the current owner, SDE represents the total cash they could expect to take home before making any financing or reinvestment decisions.

What Gets Added Back in SDE

  • Owner's total compensation (salary, bonuses, health insurance, retirement contributions).
  • Personal expenses run through the business (vehicles, travel, meals, memberships).
  • Interest expense.
  • Income taxes.
  • Depreciation and amortization.
  • One-time or non-recurring expenses (legal settlements, moving costs, equipment write-offs).
  • Discretionary expenses that a new owner might not continue.

What Is EBITDA?

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) measures a business's operating profitability independent of its capital structure, tax situation, and accounting decisions around depreciation. Unlike SDE, EBITDA does not add back owner compensation. It assumes the business will be run by a professional management team, and that management salaries are a real, ongoing operating expense.

What Gets Added Back in EBITDA

  • Interest expense.
  • Income taxes.
  • Depreciation and amortization.
  • Non-recurring expenses (with proper documentation).

Owner compensation is normalized to market rate rather than fully added back. If the owner pays themselves well above what a qualified replacement manager would cost, the difference becomes an adjustment, not the full salary.

SDE vs. EBITDA: Key Differences

Both metrics measure earning power, but the assumptions behind them are fundamentally different. The table below shows where they diverge.

Factor SDE EBITDA
Owner Compensation Fully added back to earnings. Normalized to market-rate replacement cost.
Typical Business Size Smaller, owner-operated businesses. Larger businesses with professional management in place.
Buyer Profile Individual buyers, owner-operators, searchers. Private equity firms, strategic acquirers, institutional buyers.
Underlying Assumption One owner will run the business. A management team runs the business without the owner.
Purpose Represents total cash available to a single owner. Represents operating profitability of the business as an entity.

Which Metric Applies to Your Business?

The metric that applies to your business depends primarily on two factors: the size of your business and how it is managed.

SDE Is Typically Used When

  • The business is owner-operated (the owner is essential to daily operations).
  • There is no professional management layer beyond the owner.
  • Annual earnings are in the smaller business range, where a single buyer could reasonably replace the owner.
  • The likely buyer is an individual looking to acquire a job and an income.

EBITDA Is Typically Used When

  • The business has a management team that operates independently of the owner.
  • Annual earnings are in the larger business range, where professional management is expected.
  • The likely buyers are private equity groups, strategic acquirers, or institutional investors.
  • The business has the scale and infrastructure to support professional management.

An important note. These are general guidelines, not hard rules. Some businesses in the transition zone between SDE and EBITDA may be valued using both metrics depending on the buyer. Your broker or advisor can help determine which framing positions your business most effectively.

Common Mistakes in Calculating SDE and EBITDA

⚠ Calculation Mistakes That Cost Sellers Value

Overstating add-backs. The most common mistake is aggressively adding back expenses that are not truly discretionary or personal. Buyers and their accountants will challenge every adjustment. If you cannot clearly document and defend an add-back, it may be rejected during due diligence, reducing your effective valuation.
Mixing the two metrics. Some sellers calculate SDE but present it as EBITDA, or vice versa. This creates confusion and can erode trust with buyers. Be clear about which metric you are using and ensure the calculation methodology is transparent.
Ignoring normalization adjustments. Both metrics require normalizing the financials to reflect the true economic reality of the business. This includes adjusting for above- or below-market rent (if the owner also owns the property), family members on payroll at non-market rates, and one-time events that distort earnings.
Forgetting required reinvestment. Neither SDE nor EBITDA accounts for necessary capital expenditures. A business that has deferred maintenance or needs significant equipment replacement will face scrutiny from buyers, regardless of how strong the SDE or EBITDA figure looks on paper.

Why the Right Metric Matters for Your Valuation

The metric used to value your business directly affects the buyer pool, the types of offers you receive, and the deal structures available to you. Presenting your business using the wrong metric, or calculating either metric incorrectly, can lead to misaligned expectations, extended marketing periods, or deals that fall apart during due diligence.

Why It Matters

The Metric Choice Shapes the Entire Transaction

SDE and EBITDA are not just different calculations. They point to different buyer universes, different valuation multiples, and different deal structures. A professional valuation that applies the appropriate metric, with clean documentation and defensible adjustments, gives you the strongest possible foundation for a successful sale. Getting the framing right at the start is often the difference between a smooth transaction and a process that stalls or unwinds during due diligence.
