Restaurant food cost: formula, benchmarks and how to reduce it

Food cost shows what share of revenue goes to ingredients. Here is how to calculate it, which numbers to aim for and where the kitchen loses money.

What food cost is

Food cost is the share of ingredient cost in revenue. It is calculated for a single dish, for a menu category and for the whole venue over a period.

Food cost = ingredient cost ÷ revenue × 100%

Example: a dish sells for 3,000 ₸ and its ingredients cost 900 ₸. Food cost of the dish is 900 ÷ 3,000 × 100% = 30%.

Planned versus actual food cost

Planned food cost comes from recipe cards: how much product should have gone into the dishes sold. Actual food cost comes from stock: opening stock plus purchases minus closing stock.

The gap between them is the kitchen's loss. If recipe cards say 30% and stock says 34%, four percent of revenue went past the recipe.

What a normal food cost looks like

There is no single norm; the figure depends on the format and pricing. Restaurateurs most often aim for these ranges:

FormatFood cost benchmark
Fast food, street food25-30%
Cafes and mid-range restaurants28-35%
Steakhouses, seafood35-40%
Bar, drinks18-25%

What matters more than matching someone else's norm is keeping the gap between planned and actual food cost within 1-2 percentage points.

Why actual food cost runs above planned

In a chain the first reason usually dominates: the same dish is assembled differently in different locations, and across the chain's turnover the extra grams turn into real money.

How to reduce food cost

Stock shows losses after the fact and does not say who made the mistake or on which dish. AI video analytics for restaurants checks the assembly of every dish against its recipe card as it is cooked and shows deviations by location, shift and cook.

Questions and answers

How do I calculate the food cost of a dish

Add up the cost of all ingredients on the recipe card including processing losses, divide by the menu price and multiply by 100%.

What is a good food cost

For most cafes and restaurants the benchmark is 28-35%. More important is that actual food cost from stock differs from the planned one by no more than 1-2 percentage points.

How often should food cost be calculated

Recalculate the planned figure whenever purchase prices or recipes change. Actual food cost is convenient to check weekly for key products and monthly for the whole stock.

Can a camera help reduce food cost

Yes. A camera with video analytics checks the ingredients and their count in every dish. Exact grams come from the camera paired with scales at the station.
