The quick answer
Food Cost Formula
Divide the food cost of the item by its selling price, then multiply by 100.
The formula
Food Cost divided by Menu Price × 100 = Food Cost %
Example: $4.50 ÷ $15.00 × 100 = 30%.
What Is Food Cost?
Food cost refers to the cost associated with the food ingredients used to produce a dish, portion or recipe. It typically includes the raw ingredients that go into a menu item — proteins, produce, dairy, dry goods and other components — before labor, cooking or plating are factored in.
Restaurants use food cost to understand the relationship between ingredient cost and sales price. Comparing what a dish costs to make with what it sells for is one of the clearest ways to see how efficiently a menu is priced, and it's a figure most operators come back to often.
Food cost can be tracked at the item, recipe or restaurant level, depending on the purpose of the analysis — a single dish's food cost, a batch recipe's total ingredient cost, or food cost across an entire menu or period. The exact accounting definition and reporting treatment can vary depending on a restaurant's accounting system and internal methodology, so it's worth using a consistent approach when you compare food cost over time.
The percentage
What Is Food Cost
Percentage?
Food cost percentage expresses food cost as a percentage of the selling price, or sales base, being analyzed.
For example, a food cost of $4.50 on a $15.00 menu price gives a food cost percentage of 30%: $4.50 ÷ $15.00 × 100 = 30%. In plain language, a 30% food cost means $0.30 of every $1 in menu sales is represented by the food cost used in this calculation — it does not mean that 30% is the restaurant's total cost, since labor, rent, utilities and other operating expenses aren't part of this figure.
Food cost %
Food Cost divided by Menu Price × 100 = Food Cost %
Example: $4.50 ÷ $15.00 × 100 = 30% food cost.
Four steps
How to Calculate
Food Cost
Determine the ingredient cost
Add the cost of all ingredients used in the dish or recipe.
Determine the selling price
Use the menu price for the item.
Divide cost by selling price
Food Cost ÷ Menu Price.
Multiply by 100
Convert the decimal result into a percentage.
Worked example: ingredient cost of $4.50 and a menu price of $15.00. $4.50 ÷ $15.00 = 0.30, and 0.30 × 100 = 30%. That 30% is the dish's food cost.
Batch recipes
How to Calculate Food
Cost Per Serving
Many recipes are prepared in batches rather than one portion at a time. To find the food cost of a single serving, divide the total recipe cost by the number of servings it produces. That per-serving figure can then be used as the food cost input when evaluating a menu item.
The formula
Total Recipe Cost divided by Number of Servings = Cost Per Serving
Example: $45 total recipe cost ÷ 10 servings = $4.50 per serving.
Add it up
How to Calculate
Recipe Food Cost
To find a recipe's food cost, add up the cost of every ingredient it uses. Here's a simple batch recipe made up of four ingredients:
| Ingredient | Cost |
|---|---|
| Chicken | $22.00 |
| Rice | $8.00 |
| Vegetables | $10.00 |
| Sauce | $5.00 |
| Total | $45.00 |
If this recipe makes 10 servings, the cost per serving is $45.00 ÷ 10 = $4.50. That $4.50 is the food cost of one portion, and it's the same $4.50 used throughout this guide when the dish is measured against its $15.00 menu price.
Worked example
Food Cost Example
A dish with an ingredient cost of $4.50 is priced at $15.00 on the menu. $4.50 ÷ $15.00 × 100 = 30% food cost. Subtracting the $4.50 ingredient cost from the $15.00 menu price leaves $10.50. That $10.50 is gross profit after food cost only — it is not the restaurant's final net profit, since labor, rent, utilities and other operating expenses still come out of it.
Use with judgment
What Is a Good
Food Cost Percentage?
There is no single food cost percentage that is appropriate for every restaurant. A useful target depends on the restaurant's concept, menu type, ingredient costs, pricing, labor, rent, overhead, service model, location and overall business model.
A 30% food cost can be used as a planning example, but there is no single food cost percentage that is appropriate for every restaurant. Two restaurants can run profitably at very different food cost percentages once the rest of their cost structure is taken into account.
Food Cost vs. Prime Cost
Food cost is one part of a restaurant's overall cost structure. Prime cost is a broader figure that commonly combines food-related costs, or cost of sales, with labor-related costs — though exactly what's included can depend on a restaurant's reporting methodology.
Because prime cost adds labor into the picture, it's a wider view of operating cost than food cost alone. RestoCalculator may cover broader cost calculations like this in future guides — for now, this guide focuses specifically on food cost and food cost percentage.
The relationship
Food Cost vs.
Gross Profit
Subtracting food cost from menu price gives gross profit after food cost. This figure does not account for labor, rent, utilities, marketing or other operating expenses — it only reflects what's left once ingredient cost is covered.
The relationship
Menu Price − Food Cost = Gross Profit
Example: $15.00 − $4.50 = $10.50 gross profit after food cost.
Two different numbers
Food Cost vs.
Food Cost Percentage
Food Cost
A dollar amount — the cost of the ingredients themselves.
Example: $4.50
Food Cost Percentage
A relative percentage — food cost measured against menu price.
Example: 30%
Both numbers use the same dish: $4.50 ÷ $15.00 × 100 = 30%. The dollar amount tells you what the dish costs to make; the percentage tells you how that cost compares to what it sells for — which is why restaurants track both.
Same cost, different price
How Menu Price Changes
Food Cost Percentage
Changing the selling price changes the food cost percentage even though the ingredient cost stays exactly the same. Here's the same constant $4.50 food cost at four different menu prices.
| Menu Price | Food Cost % |
|---|---|
| $12 | 37.5% |
| $15 | 30.0% |
| $18 | 25.0% |
| $20 | 22.5% |
Watch for these
Common Food Cost
Calculation Mistakes
Forgetting Small Ingredients
Sauces, garnishes, oils and condiments can contribute to total cost.
Using the Wrong Portion Cost
The cost used should correspond to the actual portion being sold.
Mixing Recipe Yield and Serving Count
Make sure the recipe yield is understood correctly.
Using Inconsistent Prices
Ingredient prices should be updated when material cost changes.
Confusing Food Cost With Total Restaurant Cost
Food cost is only one part of the overall restaurant cost structure.
Practical guidance
How to Reduce
Restaurant Food Cost
Monitor Portion Sizes
Consistent portions make food cost easier to control.
Reduce Waste
Track spoilage, overproduction and avoidable waste.
Review Ingredient Prices
Supplier prices can change over time.
Review Menu Pricing
Menu prices should be reviewed when food costs materially change.
Track High-Cost Ingredients
Identify ingredients that have a significant impact on dish cost.
Two ways to look at it
Food Cost and Inventory
Ingredient purchasing, inventory changes and actual usage can all affect a restaurant's food-cost analysis, alongside the recipe-based calculations covered above.
Theoretical / Recipe Food Cost
Based on recipe and ingredient costs, calculated on paper.
Actual Food Cost
Can incorporate actual inventory and purchasing data, depending on the restaurant's methodology.

There's no single mandatory schedule, but it's worth reviewing food cost whenever any of the following change:
Good to know
Frequently Asked
Questions
What is the formula for food cost?
Food Cost Percentage = Food Cost ÷ Menu Price × 100.
How do you calculate food cost percentage?
Divide the food cost by the menu price and multiply by 100.
How do you calculate food cost per serving?
Divide total recipe cost by the number of servings produced by the recipe.
What is a 30% food cost?
A 30% food cost means that the food cost represents 30% of the selling price used in the calculation. It does not mean that 30% of all restaurant expenses are food.
Is 30% a good food cost?
It can be a useful example or target for some restaurants, but there is no universal ideal percentage.
Does food cost include labor?
Food cost generally focuses on food or ingredient costs. Labor is usually analyzed separately, although reporting methods can vary.
What is the difference between food cost and gross profit?
Food cost is the cost of the food associated with the item, while gross profit after food cost is the selling price minus that food cost.
Can I calculate food cost for a recipe?
Yes. Add the ingredient costs to determine the total recipe cost, divide by the number of servings, and use the per-serving cost when calculating the food cost of a menu item.
