Fast food and QSR restaurants are valued on SDE multiples that reflect unit economics, franchise standing, drive-through capability, lease terms, and management independence. SDE, or seller's discretionary earnings, combines the owner's salary and benefits with adjusted net profit, representing the total economic benefit flowing to a single owner-operator. The 2.0x to 3.5x SDE range encompasses struggling single units at the low end and high-performing, drive-through-equipped franchise locations with strong management teams at the top.

Adjusted SDE calculation for a QSR requires normalizing franchise-specific expenses. A franchise unit generating $1.4M annual revenue with 30% food costs, 28% labor, 8% royalties and advertising fees, and 14% occupancy and overhead produces roughly $280K operating income at a 20% cash flow margin. Adding the owner's $65K salary and $20K in personal benefits yields $365K SDE. At 2.5x SDE the unit values at $913K. A comparable unit with drive-through, a 22% cash flow margin, a tenured GM, and 12 years remaining on the lease might command 3.2x SDE, or $1.17M, reflecting stronger unit economics and reduced operational risk.

Unit economics determine the fundamental attractiveness of any QSR to a buyer. Cash flow margin, calculated as owner cash flow divided by gross revenue, must exceed 20% to attract premium multiples. Units operating at 15-18% margins receive commodity pricing because buyers model limited upside without significant operational changes. The four-wall EBITDA margin, which excludes above-store management costs, provides a comparable benchmark across franchise systems. A McDonald's averaging 25% four-wall margins trades differently than a Subway averaging 12%. Buyers compare unit economics against franchise system averages published in franchise disclosure documents: units performing above system average command premiums while below-average units face discounts.

Drive-through capability creates the most significant structural valuation divide in QSR. Drive-through units generate 60-75% of total revenue through the window, processing orders at higher speed with lower labor per transaction than dine-in service. A QSR with drive-through averaging $1.6M revenue versus $900K for a dine-in-only location of the same brand demonstrates the economic advantage. Drive-through units consistently receive 20-35% higher multiples because revenue capacity is structurally higher. Multi-unit buyers and franchise systems overwhelmingly prefer drive-through locations. Converting a non-drive-through unit is often physically impossible due to site constraints, making existing drive-through locations inherently scarce and valuable.

Franchise standing directly affects both valuation and transaction feasibility. Franchise agreements typically run 10-20 years with renewal options. A unit with fewer than five years remaining faces franchise renewal uncertainty that depresses multiples 25-40%. Units in good standing with the franchisor, demonstrated by strong operations reviews, no default notices, and facility compliance, trade smoothly. Units with outstanding franchisor demands for remodeling, equipment upgrades, or image compliance carry capital expenditure obligations that buyers deduct from their offers. Franchisor approval is required for virtually all franchise transfers, meaning the buyer must meet franchisor financial and operational requirements. Franchise systems with active remodel mandates may require $200K-500K in near-term capital that reduces effective SDE and applicable multiples.

Lease terms establish the viability horizon for QSR operations, especially for non-real-estate-owning operators. Lenders require remaining lease terms exceeding loan amortization periods, typically seven to ten years for SBA-financed acquisitions. Units with fewer than five years remaining face buyer pools restricted to cash buyers willing to accept lease risk. Below-market rent creates embedded value: a unit paying $6,000 monthly on a lease with a market rate of $9,000 enjoys $36K in annual rent advantage flowing to SDE. Conversely, above-market leases depress cash flow and reduce effective multiples. Percentage-rent clauses, common in QSR leases, require careful analysis because they reduce margins as revenue grows. Owned real estate fundamentally changes the transaction, allowing sale-leaseback structures or combined business-and-property sales at materially higher total values.

Management team depth determines whether the buyer acquires a business or an expensive job. Units where the owner works 50-60 hours weekly on the line, manages shifts, and handles all ordering face 25-35% valuation discounts because the buyer must immediately hire a general manager at $45K-65K plus benefits. Units with a tenured general manager, two or more shift leaders, and documented operating procedures demonstrate operational independence. Buyer confidence increases with management tenure: a GM with three-plus years at the unit who has managed through staff turnover, seasonal fluctuations, and franchise inspections represents significant operational value. Multi-unit buyers specifically seek locations with strong existing management because they plan to operate remotely.

Real estate ownership creates a structural premium in QSR valuation. Owners of both the business and the underlying real estate can sell them together, sell them separately, or execute a sale-leaseback where they sell the property to a real estate investor and lease it back to the business. QSR real estate with established brand tenants sells at 5-7% cap rates, meaning a unit paying $100K in annual rent occupies property valued at $1.4M-2.0M. For owner-operators, this means the combined business and real estate value may be 2-3 times the standalone business value.

The buyer landscape for QSR includes multi-unit franchise operators expanding their portfolios within the same brand, franchise system cross-buyers diversifying into new brands, individual owner-operators purchasing their first unit, and franchise-focused investment groups. Multi-unit operators within the same system pay 2.8x-3.5x SDE because they capture management and purchasing synergies. Cross-brand operators pay 2.3x-3.0x. First-time buyers using SBA financing pay 2.0x-2.8x. Brand strength matters: premium brands like Chick-fil-A and McDonald's command higher multiples than emerging or declining brands because of established customer demand and franchisor support.
