More people fantasize about buying a restaurant than almost any other type of business. It is also one of the most unforgiving categories to buy into without understanding the specific economics. Restaurants operate on margins thin enough that small operational missteps can turn a profitable month into a loss. The failure rate is frequently cited as high (the often-quoted "90 percent of restaurants fail" is an exaggeration, but first-year failure rates of 15 to 25 percent are well-documented in academic research), and the reasons usually trace back to the same handful of structural challenges.
None of this means buying a restaurant is a bad idea. It means buying a restaurant without understanding restaurant-specific economics is a bad idea. Here are the factors that matter most.
Margins Are Thin and Unforgiving
Restaurant industry net profit margins typically run 3 to 9 percent for full-service restaurants and 6 to 12 percent for fast casual and QSR concepts, according to NYU Stern industry data and the National Restaurant Association. Compare that to service businesses (15 to 20 percent) or SaaS companies (20 percent or higher), and the margin of error becomes clear.
The three largest cost buckets are food cost (also called cost of goods sold), labor cost, and occupancy cost (rent plus related expenses). Together, these typically consume 80 to 90 percent of revenue.
Food cost for a well-run restaurant should be 28 to 35 percent of revenue, depending on the concept. Fine dining runs higher (35 to 40 percent) because of premium ingredients. Fast casual runs lower (25 to 30 percent) because of simpler menus and portion control. If the target restaurant's food cost is significantly above the benchmark for its concept type, that is either a problem (poor purchasing, waste, theft) or an opportunity (you can bring it in line through better management).
Labor cost (including wages, payroll taxes, benefits, and workers' compensation) should run 25 to 35 percent of revenue. This is the cost category most affected by rising minimum wages and labor shortages, and it has been trending upward industry-wide. Restaurants with high labor costs relative to their concept type may be overstaffed, under-automated, or in a market with wage pressure that will persist.
Occupancy cost (rent, property taxes, insurance, and common area maintenance) should ideally be 6 to 10 percent of revenue. Above 10 percent, the lease is a drag on profitability. Above 12 percent, it becomes very difficult to maintain healthy margins. The lease is the single least flexible cost in a restaurant because you cannot renegotiate it mid-term, and breaking it has severe consequences.
The Lease Is the Most Important Document
In restaurant acquisitions, the value of the business is often inseparable from the value of the lease. A restaurant cannot relocate without effectively starting over: new buildout, new permits, new customer habits, new visibility. The lease is what anchors everything.
Before making an offer on any restaurant, understand these lease terms completely:
How many years remain on the current term? A lease with 2 years remaining puts you in a weak negotiating position on renewal and creates risk for SBA financing (lenders want lease terms that extend beyond the loan maturity).
What are the renewal options and at what terms? Are rent increases capped? Are renewals at the landlord's discretion or at your option?
What is the rent as a percentage of current revenue? If it exceeds 10 percent, model whether the economics work at current revenue levels. If revenue has been declining, the rent-to-revenue ratio may be trending in the wrong direction.
Is there a personal guarantee? Nearly all commercial leases require one. Understand what you are guaranteeing and for how long. Negotiate a PG burn-off provision if possible (the personal guarantee reduces or expires after a defined number of years of on-time payment).
Are there any co-tenancy clauses, exclusivity provisions, or restrictions on concept changes? You may want to alter the menu, rebrand, or change the operating format, and the lease may restrict your ability to do so.
The Liquor License Is a Tangible Asset
In most states, liquor licenses are limited in number and transferable, making them a genuine asset with independent value. A full liquor license in a desirable market can be worth $50,000 to $300,000 or more, depending on the jurisdiction.
Some states and municipalities have caps on the number of licenses issued, creating scarcity that inflates value. Others issue unlimited licenses, making them a modest expense rather than a significant asset. Before evaluating any restaurant that serves alcohol, understand the local licensing framework: type of license (beer and wine versus full liquor), transferability process (some jurisdictions require a new application even for transfers), timeline for approval (which can range from weeks to months and may delay closing), and whether the license is held by the business entity or the individual owner.
If the license is held personally by the current owner rather than by the business, the transfer is more complex and should be addressed early in due diligence.
Staff Turnover Is the Industry's Defining Challenge
The restaurant industry has one of the highest employee turnover rates of any sector. The Bureau of Labor Statistics reports annual turnover rates in the accommodation and food services sector consistently above 70 percent, and in some segments above 100 percent (meaning the average position turns over more than once per year).
For a buyer, this means two things. First, the staff you see during due diligence may not be the staff you have three months after closing. The transition itself (new owner, potential changes to culture or operations) can accelerate departures. Second, the cost of turnover, including recruiting, training, lost productivity, and mistakes made by new employees, is a real and ongoing operating expense that is rarely visible on the P&L.
When evaluating a restaurant acquisition, ask for the staff roster with tenure data. A restaurant where most of the kitchen and front-of-house staff have been there for two or more years is a fundamentally different asset than one where the average tenure is four months. The former has institutional knowledge, customer relationships, and stability. The latter is a revolving door that will consume your time and money.
Food Cost Discipline Reveals Management Quality
Food cost percentage is the most transparent indicator of operational competence in a restaurant. A well-managed restaurant tracks food cost weekly, manages portion sizes, negotiates with suppliers, minimizes waste, and prevents theft. A poorly managed restaurant orders too much, portions inconsistently, lets inventory spoil, and pays whatever the supplier charges.
During due diligence, request 12 to 24 months of food cost data (ideally from the POS system and inventory records, not just the P&L). Look for consistency. A restaurant that maintains 30 percent food cost with minimal variance month to month is well-managed. One that swings between 28 and 38 percent has a control problem.
Also examine the relationship between menu pricing and food cost. Has the restaurant raised prices in the last two years? If food costs have risen 15 to 20 percent (as they did across the industry in 2021 to 2023) and the menu has not changed, margins are being compressed silently. You may need to raise prices post-acquisition, and you should understand how the customer base will react.
Franchise vs. Independent: Two Different Businesses
Franchise restaurants (Subway, McDonald's, Chick-fil-A, etc.) and independent restaurants are evaluated on fundamentally different criteria.
Franchise advantages: a proven concept, established brand recognition, national marketing, supply chain infrastructure, and documented operating systems. The business model risk is lower because it has been replicated thousands of times.
Franchise costs: royalty fees (typically 4 to 8 percent of revenue), marketing fund contributions (2 to 4 percent), buildout requirements, menu restrictions, and limited operational flexibility. These fees reduce the effective margin of the business and must be modeled into cash flow.
Independent advantages: full control over concept, menu, pricing, vendors, and operations. No royalties or franchise fees. The potential for higher margins if managed well.
Independent risks: no brand recognition outside the local market, full responsibility for marketing, no system-level purchasing power, and complete dependence on the current concept's appeal.
The evaluation criteria shift depending on which type you are considering. For franchises, unit-level economics (revenue, four-wall EBITDA, and same-store sales trends) are the most important data. For independents, concept defensibility, chef or owner dependence, and local competitive positioning matter more.
Valuation Benchmarks
Full-service restaurants typically trade at 2.0x to 3.0x SDE or 2x to 4x EBITDA, with the range driven by lease terms, liquor license value, concept strength, location quality, and management depth.
Fast casual and QSR concepts (especially franchises) may trade at 3x to 5x EBITDA for strong performers with proven unit economics.
Bars and breweries can trade at a premium if the liquor license has significant independent value, but the operating business itself is subject to the same margin pressures as restaurants.
The factors that consistently push restaurant multiples to the upper end: a long-term lease with favorable renewal terms, a transferable full liquor license in a limited-license jurisdiction, consistent food cost discipline below 32 percent, low staff turnover relative to industry benchmarks, and the owner's role being primarily management rather than daily operations (chef-owners create dependency risk).
