A practical guide for restaurant owners on calculate food cost restaurant menu.
Food cost is the single most important number in your restaurant's financial health. If you do not know your food cost per item, you are guessing at your prices and guessing at your margins. In 2026, with tariffs pushing ingredient costs up 37% on average, guessing will put you out of business.
Here is the math, simplified.
Example: A pasta dish uses $4.50 in ingredients (pasta, sauce, protein, garnish, oil). You charge $16. Food cost percentage: ($4.50 / $16) x 100 = 28.1%
That means 28 cents of every dollar the customer pays goes to ingredients. The rest covers labour, rent, overhead, and (hopefully) profit.
Target ranges by restaurant type:
These are guidelines, not rules. Some items will be higher, some lower. What matters is your blended food cost across the whole menu.
If your blended food cost is above 35%, you are either underpricing your menu, over-portioning, wasting too much, or buying ingredients that are too expensive for your price point. Something needs to change.
Be precise. Include everything: the main protein, the starch, the vegetables, the sauce, the garnish, the oil for cooking, the seasoning. If it goes on the plate, it goes on the list.
Check your most recent supplier invoices. If you buy a 5 kg bag of flour for $8, the cost per gram is $0.0016. If a dish uses 150 grams of flour, the flour cost for that dish is $0.24.
Do this for every ingredient. Yes, it is tedious the first time. After that, you only update it when prices change.
Sum the cost of all ingredients for one serving. That is your food cost per plate.
Divide by your menu price. Multiply by 100.
The per-item method gives you precision. The overall method gives you the big picture.
Overall food cost percentage = (Total food purchases for the period / Total food revenue for the period) x 100If you spent $12,000 on food in March and generated $38,000 in food revenue, your overall food cost is 31.6%.
Track this monthly. If it creeps up, something changed: ingredient prices went up, portions grew, waste increased, or theft is occurring.
Create a simple spreadsheet with these columns:
| Menu item | Ingredients | Cost per ingredient | Total food cost | Menu price | Food cost % |
Update ingredient costs monthly (or whenever you receive a significant price change from your supplier). Recalculate the percentages. Flag anything above your target threshold.
This spreadsheet is the most important financial tool in your restaurant. If you do not have one, build it this week.
When your food cost forces a higher menu price, your description needs to justify that price. A dish described as "chicken with rice" feels overpriced at $22. The same dish described as "free-range chicken, slow-braised in white wine with roasted garlic and served over jasmine rice with seasonal vegetables" feels like a $22 dish.
The description does not change the food cost. It changes the perceived value.
