Enter your monthly revenue and expenses to calculate your gross margin, net profit margin, food cost percentage, and prime cost ratio. See exactly where your money goes.
Restaurant profit margins are notoriously thin. According to the National Restaurant Association, the average restaurant operates on a net profit margin of just 3-5%. That means for every $100 in revenue, only $3-$5 ends up as actual profit after all expenses are paid.
The key metric to watch is prime cost — the combination of food costs and labor costs. This is the largest controllable expense in any restaurant, typically accounting for 55-65% of total revenue. If your prime cost exceeds 65%, profitability becomes very difficult regardless of your revenue volume.
| Metric | Healthy Range | Warning Sign |
|---|---|---|
| Food Cost % | 25% - 35% | Above 38% |
| Labor Cost % | 25% - 35% | Above 38% |
| Prime Cost % | 55% - 65% | Above 68% |
| Occupancy Cost % | 6% - 10% | Above 12% |
| Net Profit Margin | 5% - 15% | Below 3% |
The most impactful way to improve your profit margin is through menu optimization. By analyzing each menu item's individual food cost percentage, you can identify items that are dragging down your overall margins and either reprice them, re-engineer the recipe, or replace them entirely.
Most restaurants operate on a net profit margin of 3% to 9%. Full-service restaurants average around 3-5%, while fast-casual and quick-service restaurants can achieve 6-9%. High-performing restaurants with strong cost controls can reach 10-15%, but this is exceptional.
Gross profit is revenue minus food costs only (also called cost of goods sold). Net profit is what remains after ALL expenses — food, labor, rent, utilities, insurance, marketing, and everything else. A restaurant might have 65% gross profit but only 5% net profit after all expenses.
The three biggest levers are: (1) Menu engineering — identify and promote high-margin items while fixing or removing low-margin ones, (2) Food cost control — reduce waste, negotiate with suppliers, and optimize portion sizes, (3) Labor optimization — match staffing to demand patterns and cross-train employees.
Labor costs typically run 25-35% of total revenue. Full-service restaurants trend higher (30-35%) due to servers, hosts, and larger kitchen staff. Quick-service restaurants aim for 25-30%. Combined food and labor costs (prime costs) should ideally stay below 60-65% of revenue.
