Food Cost Percentage Calculator
Food cost percentage is the single most-watched number in any restaurant kitchen. It tells you what share of every dollar a guest spends actually goes into the ingredients on their plate. Enter your numbers below to see where you stand: the calculator updates live as you type.
Cost of every ingredient in one plated portion, including garnish and oil.
The price the guest pays for this dish.
Why food cost percentage matters
Food cost percentage converts the raw dollar cost of a dish into a number you can compare across your entire menu, against last month, and against industry benchmarks. A $4.50 dish cost sounds fine in isolation; at a $16.00 menu price it's 28.1%, healthy. Sell that same dish for $12.00 and it's 37.5%, a margin killer. The percentage is what lets you make pricing decisions with confidence instead of gut feel.
Worked example: your signature pasta costs $3.80 in ingredients (pasta, cream, mushrooms, parmesan, garnish). You sell it for $14.50. Divide 3.80 by 14.50 and multiply by 100 to get 26.2%: excellent territory. Gross profit is $10.70 per dish. If you sell 200 of these a week, that's $2,140 in gross profit from one menu item. Now compare that to a steak dish at $11.20 cost selling for $28.00: 40.0% food cost, $16.80 gross profit. The steak earns more dollars per plate but a far smaller share of its price. That tension between dollar profit and percentage margin is exactly what menu engineering is about.
Gross profit = Menu price − Ingredient cost
Practical tips for managing it
Track food cost weekly, not monthly: a month is too long to discover a problem. Separate your theoretical food cost (what your recipe cards say it should be) from your actual food cost (purchases divided by sales). A gap of more than 3 points between them almost always means over-portioning, waste, or theft, and finding which one pays for itself fast. Finally, remember food cost is only half the story: pair it with labor cost to get your prime cost, which should land under 60–65% of total revenue for a healthy full-service restaurant.
Frequently asked questions
What is a good food cost percentage?
Most restaurants target 28–35%. Under 28% is excellent and gives you room for promotions or discounts. Over 35% means your margins are thin: time to reprice, re-portion, or renegotiate with suppliers. Fine dining and steakhouses often run 35–40% because premium ingredients cost more, while quick-service spots can run 25–30%.
How do you calculate food cost percentage?
Divide the total ingredient cost of a dish by its menu selling price, then multiply by 100. For example, a dish that costs $4.50 in ingredients and sells for $16.00 has a food cost percentage of 28.1%. You can run the same calculation across a whole period by dividing total food purchases by total food sales.
How can I lower my food cost percentage?
Start with portion control: inconsistent portions are the most common leak. Then re-engineer your menu: push high-margin dishes, shrink or reprice low-margin ones, and use cross-utilization so the same ingredients appear in multiple dishes. Reduce waste with proper storage and FIFO rotation, and shop your suppliers at least once a year. Finally, raise prices strategically on dishes customers love rather than across the board.
Does food cost include labor?
No. Food cost covers ingredients only. When you add labor, you get prime cost, food cost plus labor cost, which is the real measure of operational efficiency. Most full-service restaurants aim for prime cost under 60–65% of revenue. Use our prime cost calculator to see the full picture.
