Understanding SDE: The Foundation of Business Valuation

Seller's Discretionary Earnings (SDE) represents the total financial benefit available to a working owner. It's the standard metric for valuing small businesses (typically under $5M in enterprise value) because it normalizes for the wide variety of ways owners compensate themselves.
