The Data Powering Potbelly’s Franchise Wins

Owning more than one franchise takes more than day-to-day management; it requires strategy and a clear understanding of performance metrics. For multi-unit operators in the fast-casual restaurant industry, tracking key data points such as net profit margin, same-store sales, and employee turnover provides the insight needed to build sustainable growth.

With more than 440 locations nationwide (80 of which are franchise-owned), Potbelly helps franchisees measure, analyze, and act on franchise performance metrics so they can fine-tune operations and deliver hot sandwiches that keep guests coming back.

Financial Metrics That Drive Profitability

The right KPIs for franchise owners often focus on how money is spent and earned. Below are several core financial measures every multi-unit investor should watch:

Food Cost Percentage

The food cost percentage measures the cost of goods sold (COGS), which generally includes expenses related to:

• Food items
• Beverages
• Cooking equipment
• Packaging
• Kitchen and cleaning supplies

By keeping this percentage in check, franchise owners can maintain a sustainable balance between revenue and expenses.

Labor Cost Percentage

Labor costs typically account for 30% to 40% of a restaurant’s total revenue over time, including:

• Wages
• Taxes
• Discounts
• Benefits

Understanding your restaurant’s labor cost percentage gives you a much more accurate picture of your franchise’s operations metrics, helping you figure out how specific labor costs impact your overall profits and professional efficacy.

To maintain a healthy profit margin, it’s important to keep your labor costs between 20% and 30% of gross revenue. You can accomplish this by adjusting staffing levels according to peak hours, optimizing schedules, and improving your overall operational efficiency. The lower your labor costs are, the more money you can pour back into your franchise.

Average Unit Volume (AUV) & Same-Store Sales

The average unit volume (AUV) reflects the average sales for each business location. To calculate your AUV, you’ll divide your units’ total amount of annual sales by the number of units you own.

If a franchise has a higher AUV, it could indicate a strong brand presence and an effective business model. For example, Potbelly experienced a remarkable 32% rise in franchise AUV growth from 2022 to 2024, as well as exceeding $1M in AUV for 76% of our locations in 2024.

Same-store sales growth (SSSG) measures the revenue growth of existing franchise locations for at least a year. By tracking SSSG, franchisees can gain a better understanding of the organic growth of their franchise locations by evaluating customer retention, product offerings, and market health.

Net Profit Margin

The net profit margin, also called “the bottom line” in business, is the percentage of a restaurant’s revenue after deducting all costs from gross sales. The net profit margin takes both COGS and operational costs (e.g., food, labor, rent, etc.) into consideration, helping franchise owners determine how efficiently they’re turning sales into actual profit.

Operational Metrics for Consistency

While it’s important to count the pennies being fed into your franchise, investors also need to evaluate other pivotal metrics to reach their restaurant franchise benchmarks.

Customer Satisfaction and Retention

Customer loyalty is essential for QSR brands like Potbelly. Regular surveys, review analysis, and tracking repeat visits reveal how well each location is performing and where improvements are needed to encourage retention.

Employee Turnover Rate

The employee turnover rate is an operational metric that reveals how well franchisees are managing their workforce through several factors, such as:

• The quality of training
• Efficacy of operations
• Employees’ working conditions

A high turnover rate is often a red flag and a significant financial drain, which also negatively affects employee satisfaction and customer experience at your location. By reducing turnover and fostering employee loyalty, business owners can improve operational efficiency, enhance customer service, and boost profits.

Operational Efficiency and Speed of Service

Your overall operational efficiency and the speed of service can significantly impact both customer satisfaction and profitability. Long wait times or inefficiencies in food preparation lead to frustrated customers and lost sales. To remedy this common issue in fast-casual restaurants, you can adjust staffing levels or streamline your kitchen workflows to ensure that customers get their orders as quickly as possible.

The Multi-Unit Advantage: Leveraging Data for Strategic Growth

Now that you know what franchise performance metrics to track, we’ll show you how these KPIs can help investors with multiple locations grow and establish their brand presence from day one with Potbelly.

Benchmarking Across Your Locations

Forbes reported that multi-unit operators own more than 54% of franchises in the U.S. Creating a benchmark for all your franchise units to follow demonstrates the effectiveness of utilizing a scalable business model and streamlining your workflows to better serve your customers and grow your brand.

Data-Driven Marketing and Local Store Marketing

It’s critical that multi-unit owners don’t just “rinse and repeat” with marketing campaigns that are generic and ineffective. That’s where data-driven and local store marketing can be vital resources to grow your franchise units together.

Data-driven marketing can help franchisees analyze customer behavior to automate their reporting efforts and optimize their digital presence. Franchisees can also employ local store marketing (LSM), which utilizes marketing data to craft targeted campaigns that speak to the unique customer base at each location while maximizing their marketing budget.

Forecasting and Future Planning

Proper forecasting can help investors monitor their business finances by predicting future growth, adjusting for seasonal variations, and preparing for any potential economic shifts and course-correcting whenever necessary.
