Formula, benchmarks by restaurant type, and a free calculator
Food cost percentage = (beginning inventory + purchases − ending inventory) ÷ food sales × 100. Most full-service restaurants target 28–35%. For a single menu item: ingredient cost ÷ menu price × 100.
The Food Cost Percentage Formula
Food cost percentage tells you what share of your food revenue is consumed by ingredient costs. It is one of the most-watched metrics in restaurant management because a 1–2 percentage point swing can mean the difference between profit and loss at the end of the month.
Food Cost % = (BI + P − EI) ÷ Food Sales × 100
BI = beginning inventory | P = purchases during period | EI = ending inventory
For a weekly period: if you started with $3,200 in inventory, purchased $4,500 in food, ended with $2,800 in inventory, and generated $17,500 in food sales, your food cost percentage is ($3,200 + $4,500 − $2,800) ÷ $17,500 × 100 = 28%.
Benchmarks by Restaurant Type
Restaurant Type
Target Food Cost %
Notes
Quick service / fast food
25–31%
High volume, standardized recipes, tight portion control
Fast casual
28–33%
Higher-quality ingredients but still efficiency-focused
Casual dining
28–35%
Mid-range target; labor cost is a bigger variable
Fine dining
30–38%
Premium ingredients; offset by higher check average
Bar / nightclub
18–25%
Beverage cost is lower; food plays a support role
Food truck
28–35%
Similar to restaurant; add commissary fees and fuel to full cost picture
Catering
25–35%
Depends heavily on menu complexity and event size
Per-Dish Food Cost Percentage
To price individual menu items, use the simplified version of the formula:
Or reverse it: Menu Price = Ingredient Cost ÷ Target Food Cost %
Example: a pasta dish costs $5.40 in ingredients. If your target food cost is 30%, the minimum menu price is $5.40 ÷ 0.30 = $18.00. Pricing at $17 would put you at 31.8% food cost on that dish.
Why Food Cost Percentage Spikes
Even when your numbers look right, food cost can drift upward. The most common causes:
Over-portioning — kitchen staff eyeballing portions instead of weighing
Spoilage and waste — over-ordering, poor FIFO rotation, prep waste
Supplier price increases — ingredient costs go up but menu prices don't
Menu mix shift — selling more high-food-cost items than expected
Theft — front-of-house and back-of-house together account for 2–5% shrinkage industry-wide
Definition
Prime cost is food cost plus labor cost (wages, payroll taxes, benefits). Most restaurant operators target prime cost below 65% of revenue. If food runs 32% and labor runs 28%, prime cost is 60% — leaving 40% to cover rent, utilities, and profit.
How to Lower Your Food Cost Percentage
Most operators with food cost above their target start with these four levers:
Standardize recipes and portions — written recipes with gram weights eliminate chef-to-chef variation
Take inventory weekly — monthly counts let problems compound; weekly counts catch drift early
Menu engineering — identify your high-margin "stars" and give them more menu real estate; flag loss leaders
Raise prices on high-food-cost items — even a $1 increase on your top sellers can move food cost 1–2 points
Calculate exact food cost for your restaurant, catering business, or food truck
Food cost % = (beginning inventory + purchases − ending inventory) ÷ food sales × 100. For a single dish: ingredient cost ÷ menu price × 100.
What is a good food cost percentage?
Most full-service restaurants target 28–35%. Quick-service typically 25–31%. Fine dining can run 30–38% due to premium ingredients, offset by higher check averages.
What is the difference between food cost and prime cost?
Food cost covers ingredients only. Prime cost adds labor (wages, payroll taxes, benefits) to the equation. Most operators target prime cost below 65% of revenue.
How do I lower my food cost percentage?
Start with standardized recipes, weekly inventory counts, and portion control. Then review menu pricing — pricing backward from a target food cost % ensures each dish supports your margin goals.
How often should a restaurant calculate food cost?
Weekly is standard. Monthly is a minimum. High-volume operators often track daily food cost to catch drift before it compounds.
What causes food cost percentage to spike?
Over-portioning, spoilage, supplier price increases, theft, and not updating menu prices when ingredient costs rise are the most common causes.
Can a high food cost still be profitable?
Yes — a high-volume restaurant with low labor and overhead can run 38% food cost and still profit. Food cost is one metric; labor cost, check average, and overhead matter equally.
What is ideal food cost for a food truck?
28–35%, similar to restaurants. Lower overhead (no rent) can allow slightly higher food cost, but add commissary fees and fuel to get a true picture.
How do I price a menu item using food cost percentage?
Use this formula: menu price = ingredient cost ÷ target food cost %. If your dish costs $5 in ingredients and you target 30% food cost, the minimum menu price is $16.67.
What is ideal food cost for catering?
25–35% depending on menu complexity and event size. Larger events with standardized menus tend toward the low end. Custom or plated fine dining events may run 35% or higher.
