Start with the two largest controllable expenses: food cost and labor cost. A 2-point improvement in food cost on $80,000 monthly revenue = $1,600/month = $19,200/year added directly to net profit. Compare your distributor prices first — it's the fastest win.
Enter your total revenue, food and beverage cost, labor cost, and other operating expenses (rent, utilities, insurance, marketing, supplies, repairs). The calculator returns your net profit margin — the percentage of revenue that remains as actual profit after all expenses are paid.
Net profit margin is the bottom line: it tells you whether the business is generating a return on the time, capital, and risk you've invested. Revenue growth is meaningless if margins are compressed — a restaurant doing $1.5 million in revenue at 3% margin generates the same profit as one doing $900,000 at 5%.
Full-service independent restaurants average 3-9% net profit margin. Well-run operations consistently hit 10-15%. Fast casual can reach 10-18% due to lower labor ratios. If your profit margin is below 5%, the problem is almost always in prime cost — food cost and labor cost combined are consuming too much of your revenue. The fastest lever is food cost, because you can improve it this week by comparing distributor prices and switching items to cheaper sources without changing your menu, your staff, or your hours.

A net profit margin of 5–9% is considered healthy for a full-service restaurant. Anything above 10% is excellent. Fast casual typically runs 6–9%. Fine dining can range widely: 3–10% depending on volume and cost structure. Below 3% is thin and vulnerable to any revenue disruption.
Net profit accounts for all expenses: food and beverage cost (COGS), labor cost, rent and occupancy, utilities, marketing, insurance, loan payments, POS and software fees, supplies, and any other operating expenses. Net profit is what remains after everything is paid.
Work in this order: (1) reduce food cost through supplier price comparison, (2) optimize labor scheduling to match cover counts, (3) review occupancy cost as a percentage of revenue — target under 10%, (4) audit recurring software and service fees, (5) use menu engineering to shift sales toward higher-contribution-margin items.
Restaurants are a high-fixed-cost, high-volume business with thin variable margins. The economics only work at scale — every incremental cover above break-even contributes nearly fully to profit. This is why volume, repeat customers, and tight cost control matter so much.
