SDE Multiple Valuation
Seller's Discretionary Earnings — The Gold Standard for Main Street Business Valuation
The SDE Multiple method values a business by multiplying its Seller's Discretionary Earnings — the true economic benefit flowing to a working owner — by an industry-appropriate multiple. It is the dominant method for valuing small-to-mid-size owner-operated businesses where owner compensation must be re-added to assess true profitability.
What Is the SDE Multiple Method?
Seller's Discretionary Earnings (SDE) represents the total financial benefit a full-time working owner-operator derives from a business — before taxes, interest, depreciation, amortization, and any non-recurring or discretionary owner expenses. SDE is the most relevant earnings metric for small-to-mid-size businesses where the owner's compensation, personal expenses run through the business, and managerial decisions are intertwined with reported profitability.
The SDE Multiple method applies an industry-specific multiple to this normalized earnings figure to arrive at business value. Multiples are drawn from actual closed transactions in proprietary databases, giving the result direct market validation. Unlike EBITDA — which assumes a professional management layer — SDE adjusts for a single working owner, making it the standard metric in business brokerage and Main Street M&A.
In Equitest, the SDE method is fully normalized, industry-benchmarked, and presented in Chapter 18 alongside the other market-based multiples — with clear disclosure of the multiple range and rationale used.
The SDE Formula
The resulting Business Value represents equity value directly — unlike EBITDA multiples which yield enterprise value and require a net debt adjustment.
SDE vs. EBITDA — Which Metric Applies?
The choice between SDE and EBITDA is not a matter of preference — it is determined by business size and ownership structure.
Revenue Under ~$5M
SDE is appropriate when the owner actively works in the business and their personal compensation is a significant portion of earnings. A buyer is purchasing both a business and a job — so the total owner benefit is the correct earnings metric.
Revenue Above ~$5M
EBITDA is appropriate when the business has a professional management layer that would survive an ownership change. The owner's compensation is replaced with market-rate management costs, and EBITDA reflects normalized operating earnings independent of ownership.
How Equitest Implements the SDE Method
Equitest's SDE engine is not a static spreadsheet cell. It is a fully guided normalization and benchmarking workflow spanning the financial analysis and valuation multiples modules, with industry-calibrated multiples and a reconciled conclusion.
Owner Add-Back Reconstruction
Before SDE can be computed, the reported income statement must be normalized. Equitest identifies and adds back owner compensation, personal expenses run through the business, non-recurring items, related-party transactions, and one-time revenues — producing a clean, defensible SDE figure that reflects true owner economic benefit.
Industry-Calibrated Multiple Selection
Equitest sources SDE multiples from its proprietary closed-transaction database, filtered by SIC/NAICS industry code, revenue band, and geography. The report presents the full multiple range — low, median, high — with the selected multiple clearly disclosed and justified relative to the subject company's size, growth, and risk profile.
Peer Context for Multiple Calibration
The SDE multiple is contextualized against Chapter 7's comparable company analysis — benchmarking the subject's profitability, growth rate, and revenue size against its peers. This comparative positioning justifies whether the selected multiple sits above or below the median for the sector.
Value Range Across All Methods
The SDE value is plotted in Equitest's Football Field Chart alongside the DCF, EBITDA multiple, capitalized earnings, and comparable transactions results. The chart visualizes the full range of values across methods and supports a reconciled, weighted conclusion — no single method stands alone.
The SDE Valuation Process — Step by Step
Reconstruct the Income Statement
Start from net income as reported. Equitest normalizes the financials in Chapters 8–12, identifying owner perks, related-party transactions, non-recurring revenues, and discretionary expenses that must be adjusted before SDE can be computed.
Add Back Owner Compensation
The working owner's full salary, benefits, payroll taxes, and personal expenses run through the business are added back in their entirety. This is the defining difference between SDE and EBITDA — SDE assumes the buyer will also be the operator.
Add Back Non-Cash & Non-Recurring Items
Interest expense, depreciation, amortization, and any one-time items (legal settlements, restructuring charges, pandemic-era relief payments) are added back to arrive at clean, normalized SDE.
Select the Industry Multiple
Equitest sources SDE multiples from actual closed transaction databases, filtered by industry, revenue size, and geography. The multiple reflects what buyers have historically paid for businesses similar to the subject — anchoring the valuation in real market evidence.
Apply & Reconcile
Multiply the normalized SDE by the selected multiple to derive business value. Equitest presents this alongside other valuation methods — EBITDA multiple, DCF, capitalized earnings — in the Football Field Chart, providing a reconciled range of values for a complete conclusion.
When to Use the SDE Multiple Method
Main Street Business Sales
SDE is the universal standard in business brokerage for owner-operated businesses — retail, restaurants, service businesses, trades, and professional practices — where the owner is the primary value driver.
SBA Loan Valuations
The SBA requires business valuations for 7(a) and 504 loans involving business acquisitions. SDE-based valuations are the accepted standard for businesses in the eligible size range.
Divorce & Estate Proceedings
For small business interests in marital estates or estate tax filings, SDE provides a market-based, defensible value that reflects what a willing buyer would actually pay in the open market.
Buy-Sell Agreement Funding
Partnership agreements and shareholder buy-sell arrangements for small businesses frequently specify SDE-based valuation as the mechanism for triggering buyout prices.
Pre-Sale Positioning
Business owners preparing for an exit use SDE analysis to understand how buyers will price their business and to identify adjustments — add-backs, expense normalization — that maximize value before going to market.
Business Broker Listings
The business brokerage industry uses SDE as the primary pricing metric for listings. Equitest's SDE output is formatted for direct use in broker marketing materials and confidential business review packages.
