Summary: This guide explains how to calculate Seller's Discretionary Earnings (SDE) for a restaurant acquisition, including the specific add-backs that buyers and lenders accept, a step-by-step worked example using a Newport Beach restaurant, and the DSCR math SBA lenders apply before approving a loan. Independent restaurants in Orange County have consistently traded at 2.0x to 2.5x SDE, making an accurate SDE calculation the single most important step in pricing or buying a business.

The asking price on a restaurant listing is only as credible as the earnings figure behind it. In the Orange County market, where restaurants routinely change hands between $300,000 and $1.5 million, the difference between a deal that closes and one that falls apart almost always comes down to how earnings were calculated. Buyers, sellers, and lenders are not looking at the net income line on a tax return. They are looking at Seller's Discretionary Earnings (SDE) - a normalized figure that strips away owner-specific expenses and one-time distortions to reveal the true cash the business generates for a single working owner.

Independent restaurant operators in Southern California routinely run personal expenses through the business: a family member on payroll, a personal vehicle, health insurance premiums, owner meals and travel. These are real costs on the tax return, but they are not ongoing obligations for an incoming buyer. Normalizing the financials means adding these items back to net income to arrive at SDE - the number that determines both the asking price and whether an SBA lender will approve the acquisition loan.

What Seller's Discretionary Earnings Actually Measures

The SDE formula is: pre-tax net income, plus owner total compensation (salary, draws, and benefits), plus interest expense, plus depreciation and amortization, plus any non-recurring or personal expenses run through the business. The result represents the total economic benefit available to a single owner-operator before debt service. This is the number appraisers multiply by an industry multiple to set a value, and it is the number lenders stress-test to determine whether a buyer can carry an acquisition loan.

SDE differs from EBITDA in one important way: it adds back the owner's compensation in full. EBITDA is designed for companies with professional management teams already in place. For small owner-operated restaurants in Anaheim, Irvine, and Costa Mesa - where the owner is often the manager, head chef, or primary customer relationship - SDE gives a cleaner picture of what a new owner-operator will actually earn after stepping into the business. If EBITDA is the metric for institutional buyers, SDE is the metric for everyone transacting in the small-business market.

The Add-Back Checklist: Where the Value Hides

Not every expense on a restaurant P&L qualifies as a legitimate add-back, and lenders will require supporting documentation for any item over $5,000. Start with expenses that are clearly personal or owner-specific, then move to one-time costs, and finally to accounting items that do not represent actual cash outflows. The categories below cover the most common and most meaningful add-backs in restaurant transactions across Orange County.

A Worked Example: From $52,000 Net Income to $194,000 SDE

Consider a quick-service restaurant in Newport Beach showing $52,000 in net income on its most recent tax return. At first glance, this looks like a marginal business. But the P&L reveals $90,000 in owner salary and payroll taxes, $14,000 in owner health insurance premiums, $8,400 in personal vehicle expenses, $11,200 in depreciation, and $18,600 in interest on a term loan that will be retired at closing. Adding these back to the $52,000 net income yields an SDE of approximately $194,200.

At the market multiple of 2.0x to 2.5x that independent Orange County restaurants have consistently traded at - transaction data shows restaurants under $500,000 in value sold at 2.0x SDE throughout every quarter of 2025 - this business would be priced between $388,000 and $485,000. The difference between the raw net income ($52,000) and the adjusted SDE ($194,200) is not an inflated claim. It is the correct normalization that shows what a new owner with no personal expenses run through the business will actually earn in a given year.

The buyer's job in due diligence is to verify every add-back against source documents. Owner salary comes from the W-2 and the tax return. Vehicle expenses appear on business bank statements and the vehicle's registration. Depreciation and amortization are pulled directly from the depreciation schedule attached to the tax return. Any add-back the seller cannot support with third-party documentation should be removed from the calculation before a purchase price is agreed upon.

What SBA Lenders Require: DSCR and the Add-Back Audit

SBA 7(a) loans - the primary financing vehicle for restaurant acquisitions across Orange County - require a minimum Debt Service Coverage Ratio of 1.25x. This means the business's SDE, after deducting a market-rate replacement salary for the incoming owner, must cover the proposed annual loan payment by at least 25 percent. At current SBA 7(a) variable rates in the 10.5 to 11.5 percent range, a $400,000 acquisition loan carries annual debt service of roughly $66,000 to $72,000. To pass underwriting at 1.25x DSCR, the stabilized SDE after a buyer's salary deduction would need to reach at least $82,500 to $90,000.

The phrase 'after a buyer's salary' is where many deals run into problems. SBA underwriters do not treat the full owner compensation add-back as free cash flow available for debt service. If the seller's $90,000 salary is being added back because the buyer plans to work the same daily role, the lender will still require the buyer to budget a realistic market-rate salary for themselves. For restaurant acquisitions in Southern California, lenders typically assume $50,000 to $70,000 in replacement compensation before testing DSCR. A restaurant showing $140,000 in SDE that requires full-time owner involvement may effectively underwrite at $70,000 to $90,000 in lender-adjusted cash flow - enough to service a mid-sized SBA loan, but with very little cushion.

Where Normalization Goes Wrong

The most common mistake sellers make is substituting revenue for documented earnings. Stating that a restaurant did $1.8 million in revenue last year does not help an SBA underwriter if the net after food cost, labor, occupancy, and operating expenses leaves minimal cash flow. Lenders underwrite SDE, not top-line revenue. In Southern California, food cost ratios for full-service restaurants typically run 28 to 34 percent of revenue, and labor costs another 32 to 38 percent. A restaurant with 70 percent combined food and labor costs has roughly $540,000 of gross margin left on $1.8 million in revenue, before paying rent, utilities, supplies, insurance, and everything else. The SDE comes from what remains after all operating costs, not from the headline revenue figure on the front page of the offering memorandum.

On the buyer's side, the most common error is accepting the seller's add-back schedule without independent verification. Every add-back should trace directly to a source document. If a seller claims $15,000 in personal vehicle expenses but bank statements show only a $400 per month car payment and the business is a food truck operation that depends on the vehicle for daily revenue generation, that vehicle cost is not truly addable. Buyers who close on an unverified SDE calculation often discover the real earnings gap only after the transition period ends - when they are fully committed and the seller has already moved on.

Normalizing restaurant earnings correctly requires transaction experience, access to comparable deal data, and a clear understanding of how SBA lenders will read the same numbers you are reviewing. Getting the SDE wrong by even 20 percent can shift a $400,000 asking price by $80,000 to $100,000 in either direction.
