If you want to know whether your kitchen is actually making money, you need to understand how to calculate food cost percentage. It is one of the few numbers that tells you, at a glance, how much of every rupee in sales is being eaten up by ingredients. In this guide we walk through the formula, a worked example in rupees, and what a healthy range looks like for an Indian restaurant.
What is food cost percentage?
Food cost percentage is the share of your sales revenue that goes toward the ingredients used to make the dishes you sold. It is usually measured over a period — a day, a week, or a month. A lower percentage means more of each sale is left over to cover rent, salaries, utilities and profit. A higher percentage squeezes your margins.
The food cost percentage formula
The core formula is simple:
- Food cost % = Cost of ingredients used ÷ Sales × 100
“Cost of ingredients used” is the value of the raw material that actually went into the food you sold during the period. The most reliable way to work this out is with opening and closing stock:
- Ingredients used = Opening stock + Purchases − Closing stock
This accounts for what you had, what you bought, and what is still sitting on the shelf at the end of the period.
A worked example in rupees
Say you run a mid-size restaurant and want to check your food cost for a month.
- Opening stock (start of month): ₹1,80,000
- Purchases during the month: ₹5,20,000
- Closing stock (end of month): ₹2,00,000
- Food sales for the month: ₹15,00,000
First, find the ingredients used:
- ₹1,80,000 + ₹5,20,000 − ₹2,00,000 = ₹5,00,000
Now apply the formula:
- ₹5,00,000 ÷ ₹15,00,000 × 100 = 33.3%
So one-third of your food sales is being spent on ingredients. Whether that is good or bad depends on your format — more on that below.
What is a good food cost percentage?
As general guidance, many Indian restaurants aim for a food cost in the region of 28–35%. But this varies a lot by format, and you should not treat any single number as a target:
- QSR and fast food often run leaner because of standardised portions.
- Fine dining may accept a higher food cost in exchange for premium pricing.
- Bars and cafes tend to run lower on beverages, which pulls the blended figure down.
The point is not to hit a magic number but to know your own baseline and watch how it moves month to month. A sudden jump usually signals waste, theft, portion creep, or supplier price increases.
Theoretical vs actual food cost
There are two versions worth tracking. Theoretical food cost is what your dishes should cost based on recipes and portion sizes. Actual food cost is what you really spent, calculated from stock as shown above. The gap between them is your leakage — over-portioning, spoilage, spillage or pilferage. Closing that gap is where most of the easy savings live. For a deeper look at pricing each dish correctly, see our guide on recipe costing and menu profitability.
How to keep food cost under control
Calculating the number is only half the job. To act on it:
- Count stock consistently — same day, same method, every period.
- Standardise recipes so every plate uses the same quantities.
- Track wastage separately so you can see where it comes from.
- Review supplier prices regularly, especially for high-volume items.
Doing this by hand in a register is slow and error-prone. A system that ties billing to recipe-level inventory can calculate live food cost automatically as you sell. Explore how this works with recipe-level inventory management built for restaurants.
Frequently asked questions
How often should I calculate food cost percentage?
Monthly is the minimum for reliable trends, but weekly is better for high-volume kitchens. The more often you count stock, the faster you catch a problem before it grows into a big loss.
Should food cost include spices and oil?
Yes. Any raw material that goes into a dish counts, including cooking oil, spices, garnishes and condiments. Leaving them out understates your true cost and makes the number look better than it is.
Why is my actual food cost higher than my recipe cost?
The gap usually comes from over-portioning, wastage, spoilage, or theft. Comparing theoretical cost from your recipes against actual cost from stock counts helps you find and fix the leak.
Is a lower food cost percentage always better?
Not necessarily. Cutting ingredient quality or portions too far can hurt customer satisfaction and repeat business. The goal is a sustainable balance between cost, quality and price for your format.
