Potbelly Sandwich Shop

Potbelly Sandwich Shop, also known as Potbelly Sandwich Works, began in Chicago. In 1971, founder Peter Hastings started making toasted sandwiches on an old potbelly stove inside his antique store, Hindsight, in the Lincoln Park neighborhood. He originally wanted to attract more antique buyers, but the sandwiches soon became more popular than the antiques. Peter Hastings and his wife officially founded Potbelly Sandwich Shop on January 14, 1977. The concept’s early history established the sandwich focused identity that later supported its national growth.

In 1996, loyal customer Bryant Keil saw the concept’s potential and bought the original store for $1.7 million, beginning its development into a restaurant chain. Potbelly’s headquarters are at The Gogo Building, 111 N. Canal Street, Chicago, Illinois, U.S. The company had 425 restaurants, including 80 franchises, as of January 2024. By October 2025, the system had reached 445 units. Potbelly plans to quadruple its size to 2,000 locations nationwide and move toward an 85% franchise operated model. That plan places the brand in the Limited Service Restaurants, or LSR, category and gives franchise buyers a concept with nearly five decades of operating history and a stated national expansion strategy.

The global Limited Service Restaurant market was valued at US$1.2 trillion in 2024 and is projected to reach US$1.4 trillion by 2030, representing a 3.2% compound annual growth rate. Another projection places the market at USD 737.31 billion in 2024 and USD 1214.93 billion by 2032, with a 5.71% compound annual growth rate. A separate estimate values the industry at approximately USD 823.96 billion in 2024, with growth to USD 871.02 billion by 2025 and USD 1,435.98 billion by 2034, at an annual growth rate of around 5.7% during the 2025 to 2034 forecast period. Demand for convenience, affordability, and broader dining choices supports fast casual concepts that sit between traditional fast food and full service restaurants.

Consumer habits continue to support limited service restaurants. Busy schedules have increased demand for quick service, drive thru ordering, and mobile ordering, while delivery sales in the sector rose by over 20% in the past year. Customers are also seeking healthier and more sustainable meals, prompting restaurants to adjust menus for varied dietary needs. Online ordering, mobile apps, artificial intelligence customer service, and self service kiosks are changing how restaurants operate. Digital channels represented 41% of Potbelly’s sales by the fourth quarter of 2023, and over 40% of its orders in 2025 were placed digitally or through the Potbelly Perks loyalty app. Delivery and takeout continue to serve off premise demand. Potbelly competes with brands including Jimmy John’s, Jersey Mike’s, and Subway. The Fast Food Restaurants segment is expected to reach US$626.8 billion by 2030 at a 3.9% compound annual growth rate, while the Fast Casual Restaurants segment is projected to grow at a 3.2% rate during the analysis period.

The initial franchise fee is $40,000, although some sources report a range of $20,000 to $40,000. One set of franchise data places the total initial investment at $575,600 to $1,010,000. Figures from 2025 and 2026 FDD data show a broader range of $654,000 to $1,274,000. A June 2023 report cited costs of $666,050 to $955,200. Franzy reports an investment range of $643,500 to $1,159,090, with a midpoint of $901,295. These figures indicate that opening a Potbelly shop requires substantial capital and that the estimated cost varies by source and project.

The detailed investment estimate includes an initial franchise fee of $20,000 to $40,000, three months of rent at $17,400 to $27,549, and architectural fees of $13,500 to $57,560. Construction is estimated at $450,000 to $570,000, while signage may cost $3,526 to $75,000. Furniture, fixtures, and equipment require $97,000 to $180,085, and smallwares cost $11,000 to $45,000. Technology is estimated at $8,000 to $54,665, with training costs of $4,000 to $50,000. Other expenses include 12 months of insurance at $4,000 to $9,240, professional fees of $10,000 to $20,000, business licenses and permits of $795 to $5,000, office equipment and supplies of $1,000 to $5,000, a market introduction program of $10,000 to $15,000, opening inventory of $3,698 to $20,000, and additional funds for three months of $100 to $100,000. The estimated total is $654,019 to $1,274,099. Reported net worth requirements are $500,000, with some sources citing up to $1,000,000. The liquid cash requirement is $200,000, while ideal investors are described as having $300,000 to $400,000 in liquid capital. Franzy cites minimum cash required of $643,500. Ongoing charges include a 6% royalty on gross sales and a national brand advertising fund contribution generally ranging from 3% to 4% of gross sales. RaceTrac, Inc. acquired Potbelly Corporation for $566 million in October 2025.

Potbelly shops use a counter service model. Franchisees and their teams prepare made to order toasted sandwiches, fresh salads, soups, and hand dipped milkshakes while maintaining the brand’s stated “warm, neighborhood feel” and “good vibes.” Daily management also includes digital orders and catering, which have become important revenue sources. Hiring and training employees is central to service quality and to Potbelly’s “Awesome People Creating Good Vibes” operating principle. Employee reviews mention stressful work environments, high expectations, pay concerns, and reduced hours, so franchisees should plan for active leadership and careful labor management.

The brand permits several site formats, including drive thru locations, endcaps, inline stores, freestanding buildings, and nontraditional sites. Training is mandatory before a shop opens. The Operator and General Manager Training Program takes place after the Franchise Agreement is signed and during shop development, with completion required at least six weeks before opening. It includes classroom and on the job instruction. Associate Training includes 45 hours of on the job instruction at a designated training shop. Certified Trainer and Shift Leader Training requires 60 hours at a certified training location, without a classroom component. The Managing Owner must complete a specialized four day owner course covering operating philosophy, system standards, and core skills. It includes three days of in person training during the pre construction phase, followed by hands on work at one of Potbelly’s Chicago shops and meetings with department heads. Franchisees taking a more hands on role can complete a six week operator program, ideally in Chicago, covering company philosophy, system standards, and daily operations through Potbelly’s network of 75 training shops nationwide. Continuing support includes home office resources, coaching from a franchise business consultant, operating and IT assistance, regional vendor connections, and help with real estate, construction, design, buildout, site selection, administrative work, IT infrastructure, and hiring. The standard Franchise Agreement does not provide exclusive or protected territory rights. Potbelly may operate or authorize other locations or distribution channels nearby. The company encourages multi unit ownership through a 50/50 development incentive program and a real estate process that can support simultaneous store development.

Public revenue information offers several unit level measures. Eighteen of those 38 shops, or 47%, exceeded the average. Results can vary based on location, management, and market conditions.

For the quarter ended March 27, 2022, the corresponding figures were $97.9 million and $0.3 million.
