What Is a Restaurant Profit Margin?
Your profit margin is what's left after you pay for everything — food, staff, and every overhead expense — expressed as a percentage of your total sales. If your restaurant did $25,000 in sales last week and your net profit was $3,000, your profit margin is 12%.
The restaurant industry is notoriously thin on margins. Most full-service restaurants operate between 3% and 9%, while well-run operations with strong cost control can hit 10–15%. Anything above 15% is exceptional.
What Is Prime Cost?
Prime cost is the combination of your food and beverage cost plus your total labor cost. It is the single most important number in your restaurant's finances because it represents the two costs you have the most control over week to week.
Industry standard is to keep prime cost at or below 60% of gross sales. If your prime cost is running above 65%, your business is under significant financial pressure regardless of how busy you are.
Breaking Down Overhead
Overhead costs are the fixed and semi-fixed expenses that hit you every week whether you are open or not. This calculator breaks them out individually so you can see which line is eating into your margin:
Rent — typically the largest fixed overhead expense. Industry benchmark is 5–8% of sales.
Gas — varies by season and menu. High if you run heavy kitchen equipment.
Electric — refrigeration, lighting, HVAC, and kitchen equipment all add up fast.
Insurance — general liability, liquor liability, workers comp, and property insurance.
Other — repairs, maintenance, supplies, marketing, POS fees, and anything else that does not fit above.

FAQ Section
What is a good profit margin for a restaurant? A profit margin of 10–15% is considered healthy for a full-service restaurant or bar. The average restaurant operates at 3–9%. If your margin is consistently below 5%, you need to address food cost, labor, or overhead immediately.
What is prime cost in a restaurant? Prime cost is your total food and beverage cost plus your total labor cost combined. It is the best single indicator of your restaurant's financial health. The target is to keep prime cost at or below 60% of total sales.
How do I calculate restaurant net profit? Subtract all costs — food, labor, rent, utilities, insurance, and any other expenses — from your total gross sales. The number left over is your net profit. Divide that by total sales and multiply by 100 to get your profit margin percentage.
How much should rent be as a percentage of restaurant sales? Most industry experts recommend keeping rent at 5–8% of gross sales. If your rent is above 10% of sales, it will be very difficult to operate profitably no matter how well you control other costs.
How much should labor cost be for a restaurant? Labor typically runs 25–35% of sales for a full-service restaurant. Fast casual operations may run lower. Combined with food cost, your prime cost should stay at or below 60% of sales.
How much should food cost be for a restaurant? Food and beverage cost should be 28–35% of sales for most restaurants. Bars with high liquor volume can run closer to 18–24%. Using the 25% rule as your weekly ordering target keeps you in a healthy range.
Why should I calculate profitability weekly instead of monthly? Weekly tracking lets you catch problems before they compound. A bad food cost week caught on Monday can be corrected before it turns into a bad month. Monthly P&L reviews are too slow to drive real operational change.
