Why SDE Matters
Before diving into calculations, it's crucial to understand the strategic importance of Seller's Discretionary Earnings. SDE is the language of small business valuation, providing a standardized way to view profitability from the perspective of a single owner-operator. This section explores its role for different players in an acquisition.
For a prospective owner-operator, SDE is the most important number. It answers the question: "After paying all necessary business expenses, how much cash would this business generate for me to live on?" It normalizes earnings by adding back the current owner's salary and personal perks, providing a true 'apples-to-apples' comparison between different acquisition opportunities and revealing the business's full potential cash flow to a new owner.
A seller uses SDE to maximize the perceived value of their business. Many small business owners run personal expenses through the company to minimize their tax burden, which artificially lowers Net Income. By meticulously identifying and documenting legitimate "add-backs," a seller can present a much higher SDE, justifying a higher asking price and showing buyers the true profitability of the enterprise.
Business brokers rely on SDE as a standardized metric for marketing and valuing small to medium-sized businesses. It creates a common language between buyers and sellers and forms the basis for applying industry-standard valuation multiples. Using SDE allows a broker to efficiently package a business for sale and defend its valuation during negotiations.
"For anyone pursuing an acquisition, accurately analyzing SDE isn't just about understanding profitability—it's about due diligence. An incorrect assessment of SDE can lead to a significant overvaluation, turning a promising investment into a costly mistake. Conversely, a precise SDE analysis reveals the true earning power, unlocking genuine opportunities for growth and value creation."

What Is SDE? Components & Definitions
SDE is calculated by taking a business's pre-tax earnings and adding back specific items. Understanding what qualifies as an "add-back" is the key to accurately calculating SDE. This section breaks down the core components and helps you differentiate SDE from other common financial metrics.
Seller's Discretionary Earnings (SDE)
SDE represents the total financial benefit a single full-time owner-operator would derive from a business on an annual basis. It is calculated before interest, taxes, non-cash expenses, one owner's compensation, and discretionary items.
The "Add-Backs" Explorer
Owner's Salary
The compensation the current owner pays themselves. This is added back because a new owner will set their own salary.
Discretionary Expenses
Personal expenses run through the business, like personal car leases or family travel, that are not essential for operations.
Non-Recurring Expenses
One-time costs, like a major lawsuit settlement or a unique repair, that are not expected to occur again.
Non-Cash Expenses
Expenses like depreciation and amortization that reduce taxable income but don't represent an actual cash outlay.
Interest Expense
Added back because a new owner will have a different debt structure. SDE reflects the business's performance independent of its financing.
Related Party Perks
Salaries or benefits paid to family members for minimal work, or above-market rent paid to a property owned by the seller.
