Enter your dish cost to the business and menu price to the customer to calculate your food cost percentage. You'll see your food cost %, expected profit, and profit margin — giving you a clear picture of whether your menu pricing is working for your restaurant.

Most thriving restaurants aim to keep food costs between 28% and 35% of their total food sales. If your food cost percentage is below 28%, you may be under-portioning or using lower-quality ingredients. Above 35% means you're likely losing profitability and need to adjust pricing or reduce ingredient costs.
Food cost percentage is calculated by dividing the dish cost by the menu price and multiplying by 100. For example, if a dish costs $4.50 to prepare and sells for $14.99, the food cost percentage is ($4.50 ÷ $14.99) × 100 = 30.02%. This tells you how much of every dollar of revenue goes toward food costs.
Food cost percentage is one of the most critical metrics in restaurant management. It directly impacts profitability — even a few percentage points can mean the difference between a thriving business and one that struggles. Monitoring it helps you make informed decisions about menu pricing, portion control, and supplier negotiations.
There are several strategies: negotiate better deals with suppliers, reduce food waste through proper storage and prep, standardize portion sizes, engineer your menu to promote high-margin dishes, and regularly audit your inventory. Even small improvements in each area can significantly lower your overall food cost percentage.
Food waste is one of the leading causes of a high food cost percentage. Overproduction, spoilage, and improper portioning all contribute. Tracking waste daily, training staff on proper storage techniques, and using FIFO (first in, first out) inventory management can help minimize unnecessary losses.
Inconsistent portioning leads to unpredictable food costs. If kitchen staff serve varying portion sizes, your actual food cost percentage will fluctuate even if your menu price stays the same. Using standardized recipes, portion scales, and pre-measured prep can keep portions — and costs — consistent.
Your menu price is the denominator in the food cost percentage formula, so raising prices (while keeping ingredient costs the same) directly lowers your food cost percentage. Before increasing prices, consider your market positioning, competitor pricing, and customer price sensitivity to find the right balance.
Both approaches are valuable. Calculating per dish — as this calculator does — helps you identify which items are most and least profitable so you can adjust pricing or recipes. Overall restaurant food cost percentage gives you a macro view of operational efficiency and is useful for financial reporting and benchmarking.
