Running a restaurant today means operating on razor-thin margins. With over 1 million restaurant locations across the U.S. and average profit margins between 3% and 5%, success depends on how well operators measure and act on their performance data. That’s where restaurant key performance indicators (KPIs) come in — the critical metrics that reveal whether your restaurant is truly profitable, efficient, and delivering great guest experiences.

Tracking the right restaurant KPIs helps operators see exactly where money is made or lost — from food costs and labor efficiency to table turnover and customer retention. But here’s the challenge: most restaurants still track KPIs manually, losing valuable time and insights.

Modern, AI-native platforms like NOVA automate KPI tracking in real time, helping operators monitor prime cost, sales trends, and guest satisfaction — and turn data into action before issues impact the bottom line.

So, what exactly are restaurant key performance indicators, and which ones matter most for growth and profitability? Let’s break them down.

Understanding Restaurant Key Performance Indicators
‍

Restaurant Key Performance Indicators (KPIs) are measurable values that help operators track the health and performance of their business. From sales and labor efficiency to customer satisfaction, KPIs provide actionable insights that guide smarter decisions, optimize operations, and drive growth. Monitoring the right metrics ensures your restaurant stays profitable, efficient, and competitive.

Here are 15 essential KPIs that every restaurant operator must be aware of.

Financial Performance KPIs

Break-Even Point

Break-even point is one of the primary metrics restaurants must track, as it tells them whether the restaurant can sustain itself in the market.  

Break-even point = Total fixed costs / [(Total sales - Total variable costs) / Total Sales]

For instance, the restaurant’s total sales amount to $20,000, and fixed and variable costs are $4,000 and $2,000, respectively.  

Break-even point = 4000 / [(20000-2000) / 20000] = $4444.44

Hence, the restaurant needs to earn more than 4444 dollars to cover the expenses and make a profit.  

COGS  

COGS, or Cost of Goods Sold, determines the total cost incurred to procure and prepare all the elements used in creating the menu items. Too high COGS leads to less profitability. On the other hand, you must not compromise the food quality to reduce COGS. Operators must select a specific period to calculate COGS. It is calculated as:

COGS = (OI+P-EI) / S  

Where:  

OI = Opening Inventory (cost of food at the start of the period)

P = Product (new inventory brought during the period)

EI = Ending Inventory (food left at the end of the period)

S = Sales (total food sold during the period)

As per Oracle, the average COGS should be 30% or less, with 30% for food sales, 15% or less for nonalcoholic beverages, and a cost range of between 18% and 40% for liquor.

Prime Cost

Prime cost signifies the total operational costs incurred by a restaurant. In addition to the COGS explained above, prime cost also includes labor costs. To calculate labor costs, you must consider payroll parameters like wages, training, benefits, and taxes.  

Prime Cost - Labor Costs + COGS

You can calculate the prime cost percentage by considering the prime cost as a factor of sales.  

Prime Cost Percentage - Prime Cost / Sales x 100

Labor Cost Percentage

The labor cost percentage measures the total labor cost as a factor of the total revenue generated. It gives you a measure of the staff’s efficiency. A higher labor cost percentage indicates that you must evaluate the labor management process.

Labor Cost Percentage = Total Labor Costs / Total Revenue Generated

Sales KPIs

Average Check Size  

The average check size reveals how much customers spend on average. It can be an indicator of customer satisfaction and food quality. You can increase the average check size through personalized recommendations and upselling.

Average Check Size = Total Sales / Total Transactions

Gross Profit Margin

To calculate gross profit margin, we have to calculate gross profit first. It is calculated after deducting COGS from the total sales.  

Gross Profit = Total Sales - COGS

The gross profit margin reflects the actual profit the restaurant is making.

Gross Profit Margin = Gross Profit / Total Sales x 100

Table Turnover Rate

Table turnover rate determines the number of guests that sit at a single table during a period. Faster turnover means more guests served, leading to higher revenue. However, it does not mean that you rush the customers in order to ensure faster turns. Table turnover is calculated as -

Table Turnover Rate = Number of Parties Served / Total Number of Tables

For instance, if your restaurant has 50 tables and you have served 300 guest parties in a day, the turnover rate would be 6.    

Customer Retention Rate (CRR)

Customer retention is a major concern for any operator, as the average retention rate for the restaurant industry is only 55%. Hence, every restaurant must track the customer retention rate to ensure repeat visits.

Customer Retention Rate = [(Customers at End of Period – New Customers) / Customers at Start of Period] × 100

Employee-Related KPIs

Employee Turnover Rate  

Employee turnover rate is the speed at which employees leave your restaurant. It is an essential indicator to assess the working culture and employee satisfaction.  

Employee Turnover Rate = (Number of Employees Who Left / Average Number of Employees) × 100

The hospitality industry has a turnover rate of over 73%. Hence, you must ensure a low employee turnover rate to reduce training and hiring costs.

Per-Person Average (PPA)

PPA is the average sales made by a server. It is a useful KPI to measure employee productivity during a given period. PPA is calculated as -  

PPA = Total sales made by a server / Total number of guests served

A server can increase the PPA through upselling, loyalty programs, and personalized services.  

Marketing KPIs

Engagement Rate  

Engagement rate is a vital KPI to analyze a restaurant’s brand visibility and image. A high engagement rate means higher user interactions, which leads to an increase in footfall.  

Engagement Rate = (Total Engagement / Total Impressions) x 100

You must track the engagement rate of different platforms to identify which marketing channel works the best.  

Click-through Rate

Click-through rate determines the percentage of people who click on a link after seeing an ad, email, or post.  

Click-through rate = (Total Clicks / Total Impressions) x 100

A low click-through rate implies that you need to work on your messaging.  

Net Promoter Score  

NPS measures how likely customers are to recommend your restaurant. The customers are requested to give their ratings through different channels on a scale of 1-10. Customers who give a rating of  

• 9 or 10 are called promoters

• 7 or 8 are called passives

• 0 to 6 are called detractors  

NPS is calculated by:

NPS = (% of Promoters) - (% of Detractors)

High NPS reflects strong service and quality, while a low score shows areas needing immediate improvement.

Redemption Rate

Redemption rate indicates the performance of your loyalty program. It tells you the number of people who actually find the offers attractive.  

Redemption Rate = (Total Rewards Redeemed / Total Rewards Issued) x 100

A high redemption rate means your promotions are relevant and timely. Regularly analyzing redemption rates allows you to fine-tune promotions to maximize both engagement and revenue.

Customer Acquisition Cost (CAC)

This KPI tells you the overall performance of your marketing function. It is calculated as:

CAC = Total Cost of Marketing / Number of Customers Acquired

Restaurants need to ensure a low CAC by automating marketing functions through new-age tools like NOVA. Tracking CAC regularly helps you streamline the marketing process and identify challenges.  

Benchmarking: What “Good” Looks Like for Restaurant KPIs

Tracking numbers is one thing—understanding what they mean in the context of the wider industry is what makes KPIs powerful. Restaurant operators often ask, “Am I doing well, or falling behind?” Benchmarks provide that clarity.

Here are a few industry averages to help you gauge performance:

Cost of Goods Sold (COGS):

• Food: ~30% of sales

• Non-alcoholic beverages: ≤15%

• Alcohol: 18–40% depending on type

👉 If your COGS is higher than these ranges, it’s a sign of supplier issues, waste, or portion control problems.

Labor Cost Percentage:

• Healthy range: 25–35% of total sales

👉 Beyond 35% usually signals overstaffing, inefficient scheduling, or training gaps.

Table Turnover Rate:

• Casual dining: 3–4 turns per table per night

• Fine dining: 1–2 turns per night

👉 Too low may indicate slow service; too high could compromise guest experience.

Net Promoter Score (NPS):

• Restaurants average: 20–30

• Top performers: 50+

👉 If your NPS is below 20, guest satisfaction programs and loyalty initiatives need attention.

Customer Retention Rate:

• Industry average: ~55%

👉 If you’re retaining less than half your guests, it’s costing you more in marketing to replace them than to keep them.
