Food Cost: How to Calculate and Control Kitchen Costs

May 18, 2026

Food cost is not a number for the accountant. It is the mirror of your kitchen. It tells you how well you organise, how much you are losing and where there are gaps you are not seeing.

What Food Cost Is and Why It Concerns You

Food cost is the percentage of your ingredient cost relative to revenue. A simple concept with enormous significance.

Many cooks believe this is the manager's or owner's job. Wrong. If you design menus, if you order ingredients, if you train a team, food cost concerns you directly. Because every decision you make inside the kitchen affects this number.

Simple explanation. If a dish costs you 3 euros to make and you sell it for 10 euros, your food cost is 30 percent. That simple.

How It Is Calculated

The formula is straightforward:

Food Cost % = (Cost of Ingredients / Revenue) x 100

To calculate it properly you need:

Cost of Ingredients = Opening Inventory + Purchases - Closing Inventory
Example. Opening inventory 500 euros, purchases 1,200 euros, closing inventory 400 euros. Cost of ingredients: 1,300 euros. If revenue is 4,000 euros, your food cost is 32.5 percent.

What the Numbers Mean

There is no single correct food cost for all kitchens. It depends on the concept, the pricing, ingredient quality and the business model.

25 to 30 percent. Good control. Efficient operation. Common in fast casual and bistro settings.
30 to 35 percent. Acceptable for most restaurants. Good balance of quality and cost.
35 to 40 percent. High. Justified only in fine dining with premium ingredients. If you are not there, something is wrong.
Above 40 percent. Dangerous. Requires immediate analysis and action.

The Most Common Reasons It Rises

Food cost does not rise by chance. There is always a reason. And it is usually one of these:

Important. Not all of these need to happen at the same time for food cost to go wrong. Just one of them, repeated daily, is enough.

How to Keep It Under Control

There is no magic solution. There is discipline, system and consistency.

  1. Weigh everything. Standard portions for every dish. Every time. No exceptions.
  2. Do inventory regularly. Weekly or every two weeks. You know what you have, what went out, what was lost.
  3. Apply FIFO strictly. Less waste means lower cost.
  4. Calculate the cost of every dish. Before you set a price, know what it costs you.
  5. Use every ingredient. Bones for stock, trimming for soups, stale bread for croutons. Zero waste is not just ideology. It is profit.
  6. Train the team. If they do not know why it matters, they will not pay attention to it.
Immediate action. If your food cost is high right now, start with FIFO and portioning. These two alone can bring the percentage down noticeably within a few weeks.

Food Cost and Menu Pricing

Many set menu prices based on what neighbouring restaurants charge or on instinct. That is wrong.

Every dish must be priced based on its actual cost. If the ingredient costs you 4 euros and you want a 30 percent food cost, the selling price must be at least 13.30 euros.

Selling Price = Ingredient Cost / Target Food Cost %

That is the formula. It does not mean you always charge exactly that price. The market has its own limits. But you know where your floor is and what you are actually earning.

Smart strategy. Dishes with low ingredient cost can offset those with high cost. Menu design is not only about flavour. It is also mathematics.

The Chef Who Understands Numbers Wins

You do not need an accounting degree. You need to understand what the numbers mean and how your decisions affect them.

The chef who knows their food cost speaks differently with the owner. They have arguments. They have data. And they make decisions based not on estimates but on reality.

That is the modern Head of Kitchen Operations. Not only a cook. Also a business-minded professional.

Final thought. Food cost does not limit you. It frees you. Because when you know the numbers, you know where you have room to create and where you need to apply discipline.

Questions and Answers

What is food cost?

The percentage of ingredient cost relative to revenue. Calculated as ingredient cost divided by revenue multiplied by 100. It is the key efficiency indicator of every kitchen.

What is the ideal food cost?

Between 25 and 35 percent for most restaurants. In fine dining it can reach 40. Above that requires immediate analysis.

What factors increase food cost?

Poor FIFO, incorrect portions, over-ordering, poor storage, pricing without cost analysis and trimming that gets thrown away instead of being used.

How do you reduce food cost without cutting quality?

With proper FIFO, accurate portions, regular inventory, utilising ingredient offcuts and smart menu pricing. Quality and cost control go together.

Should the chef know the costs?

Yes. You cannot design menus, order or train properly if you do not understand the economics behind every dish. It is professional knowledge, not accounting.
