SDE and EBITDA are the two most common financial metrics used to value businesses in M&A — but they measure different things, apply to different business sizes, and produce very different valuation numbers on the same business. Using the wrong metric — or not understanding which one a buyer will apply to your business — is one of the most common sources of valuation gap in mid-market deal negotiations. Learn the full framework in Exit Ratio 360™.
What is the difference between SDE and EBITDA?
SDE — Seller’s Discretionary Earnings — adds back the owner’s salary, benefits, and other owner-specific perks to net income in addition to the standard EBITDA add-backs. It measures the total financial benefit the current owner derives from the business. EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization — measures the business’s operating profitability independent of how it is capitalized or owned. SDE is used for smaller owner-operated businesses where the owner works full-time in the business. EBITDA is the standard metric for mid-market transactions where a buyer will install professional management.
What is the difference between SDE and EBITDA?
SDE adds back the owner’s salary, benefits, and perks to measure total financial benefit to the current owner. EBITDA measures operating profitability independent of ownership structure. SDE is used for owner-operated businesses under $3M enterprise value. EBITDA is the standard mid-market metric where buyers install professional management rather than operate the business themselves.
What size business is valued on SDE versus EBITDA?
Businesses with enterprise values below $2 million to $3 million and owner-operated structures are typically valued on SDE. Businesses above $5 million in enterprise value are typically valued on EBITDA. The $3 million to $5 million range is transitional — where the business falls depends on whether a buyer would operate the business themselves or hire management. See also: EBITDA Multiple.

Businesses under $2M to $3M enterprise value are typically valued on SDE. Businesses above $5M enterprise value are valued on EBITDA. The $3M to $5M range is transitional — where it falls depends on whether the buyer would operate the business themselves or hire professional management.
How is SDE calculated?
SDE calculation starts with net income, then adds back owner salary and benefits, personal expenses run through the business, depreciation and amortization, interest expense, taxes, and any other one-time or non-recurring items. SDE multiples for small businesses typically range from 2x to 4x depending on industry, growth, and risk profile. A business with $300,000 in SDE might sell for $600,000 to $1.2 million at those multiples.

How is EBITDA calculated?
EBITDA starts with net income and adds back interest expense, income taxes, depreciation, and amortization. Adjusted EBITDA — which is what buyers actually use in mid-market transactions — further adds back owner’s salary replacement cost if the owner takes below-market compensation, one-time non-recurring expenses, and any personal items run through the business. As of Q1 2026 mid-market EBITDA multiples in professional services range from 5x to 10x depending on owner independence, recurring revenue quality, and industry growth dynamics.

Why does the distinction between SDE and EBITDA matter for your exit?
It matters because buyers apply multiples to the metric they choose — and a significantly different multiple applied to a significantly different earnings figure produces a very different headline number. A seller who presents their business using SDE thinking while a PE buyer underwrites it on EBITDA will have a valuation gap that derails negotiations. Understanding which metric your likely buyer will apply before you go to market allows you to prepare your financials, normalize your add-backs, and price your business correctly.

Buyers apply multiples to whichever metric they choose — and different metrics on the same business produce very different valuations. A seller presenting SDE while a PE buyer underwrites on EBITDA creates a valuation gap that derails negotiations. Understanding which metric your buyer will apply before going to market allows you to price your business correctly for your target buyer type.
What is adjusted EBITDA and how does it differ from EBITDA?
Adjusted EBITDA adds back specific items beyond the standard EBITDA add-backs to produce a more accurate picture of normalized operating profitability. Common adjustments include owner salary to market-rate replacement cost, one-time legal expenses, non-recurring marketing or consulting costs, and personal expenses run through the business. Buyers will scrutinize every add-back and challenge any that appear to inflate the earnings base. See also: How Buyers Calculate Business Valuation.

Adjusted EBITDA adds back items beyond the standard EBITDA add-backs to produce normalized operating profitability. Common adjustments include owner salary to market-rate replacement, one-time legal expenses, non-recurring consulting costs, and personal expenses. Buyers scrutinize every add-back — having documented rationale for each one reduces friction significantly.
What add-backs are legitimate in EBITDA calculations?
Legitimate EBITDA add-backs are expenses that are non-recurring, owner-specific, or structurally different under new ownership. Examples include one-time legal settlements, the portion of owner compensation above market-rate replacement cost, personal vehicle expenses, personal travel expenses, and non-recurring capital expenditures. Inflated or unsupportable add-backs discovered during diligence are one of the most common deal retrade triggers in mid-market M&A.
What add-backs are legitimate in EBITDA calculations?
Legitimate add-backs are non-recurring, owner-specific, or structurally different under new ownership — one-time legal settlements, excess owner compensation, personal vehicle and travel expenses, non-recurring capital expenditures. Illegitimate add-backs are recurring business expenses that continue under any ownership. Inflated add-backs discovered in diligence are one of the most common deal retrade triggers.
How do you prepare your financials for an EBITDA-based valuation?
Start three years before going to market and work with a CPA or financial advisor to separate personal from business expenses, normalize your compensation to market-rate replacement, document the rationale for every add-back, and reduce the number of adjustments needed. The business that requires 15 add-backs to reach a defensible EBITDA number will have every one challenged. See also: Clean Financials.

What is a quality of earnings report and why does it matter for SDE or EBITDA?
A quality of earnings report is an independent financial analysis — typically conducted by a CPA firm — that validates the business’s financial statements, scrutinizes add-backs, and assesses the sustainability of the earnings base. Sellers who commission their own sell-side Q of E before going to market find the problems first, address them on their terms, and arrive at the table with pre-validated financials. A sell-side Q of E typically costs $15,000 to $40,000 and can save multiples of that in avoided multiple compression or deal collapse.
