What is Seller's Discretionary Earnings (SDE)

Definition of SDE

Seller's Discretionary Earnings (SDE) represents the total financial benefit available to a single owner-operator of a business. It's the primary metric used to value small businesses (generally those under $5 million in value).

SDE answers the question: 'How much money does this business put in the owner's pocket?'

The formula:

SDE = Net Income + Owner's Salary + Owner's Benefits + Non-Recurring Expenses + Non-Cash Expenses (Depreciation/Amortization) + Interest Expense

How to Calculate SDE Step by Step

Start with the business's net income from the tax return or P&L statement, then add back:

1. Owner's salary and wages: The total compensation paid to the owner (including payroll taxes)
2. Owner's benefits: Health insurance, life insurance, retirement contributions, personal vehicle expenses, personal travel charged to the business
3. Non-recurring expenses: One-time costs that won't repeat (lawsuit settlement, major repair, moving costs)
4. Depreciation and amortization: Non-cash expenses that reduce reported income but don't represent actual cash outflows
5. Interest expense: Financing costs related to the current owner's debt (the buyer will have their own financing structure)
6. Personal expenses: Any personal expenses run through the business (meals, entertainment, family cell phones, etc.)

Example calculation:

• Net income on tax return: $50,000
• Owner's salary: $80,000
• Owner's health insurance: $12,000
• Owner's vehicle: $8,000
• One-time legal settlement: $15,000
• Depreciation: $20,000
• Interest: $5,000
• SDE = $190,000

SDE vs. EBITDA

Buyers and sellers sometimes confuse SDE with EBITDA. The key difference:

• SDE includes the owner's salary add-back. It represents the total benefit to an owner-operator.
• EBITDA does NOT add back the owner's salary. It assumes the business pays a market-rate manager.

For a business where the owner earns $100,000:

• SDE might be $250,000
• EBITDA might be $150,000 (SDE minus the owner's salary)

When to use SDE: For owner-operated small businesses where the buyer will work in the business.

When to use EBITDA: For larger businesses, investor acquisitions, or businesses with professional management in place.

Common SDE Mistakes

Sellers often over-calculate SDE by:

• Adding back legitimate business expenses as 'personal'
• Including revenue that doesn't actually exist (unreported cash claims)
• Forgetting that the buyer's accountant will verify every add-back

Buyers should watch for:

• Unsubstantiated add-backs (every add-back should be documented)
• 'Normalized' SDE that assumes cost reductions or revenue increases that haven't happened
• Missing expenses that the seller covers personally but the buyer will need to pay
• Aggressive depreciation that masks ongoing capital expenditure needs

The best practice is to calculate SDE conservatively and let the buyer draw their own conclusions. Credibility in the SDE calculation builds trust and leads to faster, smoother transactions.

Key Takeaways

Business valuation is both an art and a science. While formulas and multiples provide a starting framework, the actual value of a business depends on market conditions, buyer motivation, and negotiation. Work with a qualified business appraiser or experienced broker to get an accurate valuation before buying or selling.
