SDE (Seller's Discretionary Earnings)
EBITDA plus owner's total compensation and discretionary benefits — the primary earnings measure used to value owner-operated small businesses (typically under $1-2M of SDE), where the owner's compensation is material to profit.
Full Definition
SDE is the small-business equivalent of Adjusted EBITDA. It starts from EBITDA and adds back the full compensation, benefits, and personal expenses of one working owner. The underlying concept: in a small business where the owner works full-time, their compensation is a hybrid of salary for services and profit distribution. For valuation purposes, adding back the owner's total comp shows the true "earning power" for a single-owner-operator buyer — most commonly used in business broker transactions involving individual buyers.
How it actually works: SDE calculation: Net Income + Interest + Taxes + Depreciation + Amortization + one working owner's full W-2 compensation + one owner's benefits (health insurance, retirement, auto, etc.) + personal expenses run through the business. Multiples for SDE are typically lower than EBITDA multiples — often 1.5-3.5x SDE for most small businesses, because the "one owner" is already fully compensated out of SDE.
Key distinction from Adjusted EBITDA: Adjusted EBITDA normalizes owner compensation to market (what you'd pay a replacement), leaving a normalized earnings number. SDE adds back all owner comp, leaving a pre-compensation earnings number. A business with $800K SDE has roughly $500-600K Adjusted EBITDA (after deducting market comp of $150-200K for a replacement owner). This is why SDE multiples are lower — the buyer has to pay themselves out of SDE.
SDE is most useful for businesses under ~$2M of earnings where owner work is central. Above that threshold, businesses typically transition to Adjusted EBITDA valuation as operations become less owner-dependent and more institutional.
Seller vs. Buyer Perspective
If your business generates $300K-$1.5M of SDE, SDE-based valuation is probably your framework. Understand what multiples your industry commands — retail 2-2.5x, professional services 2.5-3.5x, wholesale 2-3x, specialized manufacturing 3-4x. Maximize SDE by documenting every legitimate add-back: owner W-2, spouse salary without operational role, personal vehicles, personal travel, home office, phone, meals, country club. Each dollar of SDE is 2-4x in purchase price. But don't inflate — buyers reject aggressive SDE claims, and failed deals hurt your credibility. Use a sell-side broker experienced in your industry for realistic SDE presentation.
Buyers of SDE-valued businesses are typically individuals using SBA financing. Your SDE calculation must be defensible — the lender's QoE will validate every add-back. Key test questions: (1) Is the add-back truly discretionary? Personal expenses yes; necessary business expenses no. (2) Is there one working owner or multiple? SDE adds back one owner's comp, not all. (3) Does the business run without the owner? If so, Adjusted EBITDA framework may be more relevant. (4) Will replacement owner-operator compensation be adequate at the post-sale scale? After SDE for debt service, taxes, and living, the buyer needs enough income to live on.
Real-World Example
A retail business reports: Revenue $2.1M, COGS $1.05M, Operating Expenses $780K, Depreciation $35K, Interest $18K, Net Income $175K. Owner W-2: $95K, benefits $28K. Personal expenses: $22K vehicle, $15K personal travel/meals labeled as marketing. EBITDA calculation: $175K + $18K + $12K tax + $35K + $0 amortization = $240K. Adjusted EBITDA: $240K + $0 (owner W-2 is already below market for retail manager) + $37K (personal expenses) = $277K. SDE: $240K + $95K W-2 + $28K benefits + $37K personal = $400K. At 2.5x SDE multiple: $1.0M enterprise value. At the 4.5x Adjusted EBITDA multiple typical for small retail: $1.25M — slightly higher but reliant on the "market compensation" concept. SDE framework prevails for this size deal, targeted at individual buyer with SBA financing. Buyer will work full-time replacing the owner's role, with $400K annual SDE to cover their salary ($120K reasonable owner comp), SBA debt service ($140K on $850K loan), taxes ($50K), leaving $90K of true excess for working capital and personal reinvestment.
Why It Matters & Common Pitfalls
- !SDE vs. Adjusted EBITDA blur. Rule of thumb: under $1M earnings use SDE; above $2M use Adjusted EBITDA; $1-2M varies.
- !"One owner" assumption. SDE adds back one owner's compensation. If the business has 2-3 working owners, only one is fully added back.
- !SBA implications. SBA DSCR calculations work off SDE minus reasonable replacement owner comp. Buyers must live on what remains.
- !Industry multiples. SDE multiples vary widely: low for commoditized retail, higher for specialized services. Know your segment.
- !Documentation matters. Every add-back needs documentation. Undocumented adds get cut.
- !Size threshold transition. As businesses grow past $2M SDE, they typically sell at Adjusted EBITDA multiples. Growing past the transition improves valuation math significantly.
- !Owner transition risk. SDE-valued businesses are heavily owner-dependent. Transition planning matters to buyers.
