In the best of times, running a restaurant can be a challenge, with tight margins, high turnover,  and a demanding schedule. In the past few years, it has become even more difficult.

Restaurants across the country are facing dire circumstances. One way that many restaurant owners can tighten their belts and increase their profits is through calculating their food cost percentages. This technique can be used at any time, not just during a health crisis.

Determining your food cost percentage is the most effective way to ensure that your restaurant thrives. By taking a close look at your food costs, you can tailor your menu and make changes to remain profitable. Below, we outline the basics about food cost percentage, including how you can calculate it for your own menu.

What Is Food Cost Percentage?

Food cost percentage is a way to determine how much your restaurant makes on any given dish. An item’s food cost is the ratio of ingredients and the revenue that those ingredients generate when sold. It is always expressed as a percentage.

Food cost is often used to determine the price of a dish in a restaurant. Business owners want to make sure that they aren’t selling their product at a loss, so they use this number to set a price. For example, if a restaurant sells a basket of chicken wings that has $3.00 in ingredients (chicken, sauce, celery, blue cheese dressing), then it will want to set the price for that basket of wings at something over $3.00 based on their preferred food cost percentage.

What Is A Good Food Cost Percentage?

There really isn’t a single percentage that could be considered good for the entire restaurant industry. Food cost percentage is going to vary depending on a number of factors, including: location, type of food served, complexity of dishes, and more.

While there may not be a “good” food cost percentage, you can benchmark your food cost percentage against the average range. On average, many restaurants aim to keep food costs between 28 and 35% of their revenue. This number can vary significantly based on a particular business’ needs. Fast food restaurants or restaurants in smaller towns can still operate profitably with a food cost percentage above 35%.

Why Is Food Cost Percentage Important?

Food cost is one of the key indicators of profitability for a restaurant. If a restaurant allows its food costs to get too high in relation to menu prices, its profit margins become even tighter — and the business may fail.

Restaurants run on incredibly tight margins as it is. Any change in the price of goods or the number of sales can significantly affect a restaurant’s bottom line. For example, if the price of meat shoots up (as it has during the COVID-19 pandemic), then it can impact profitability unless the menu price changes as well.

By closely monitoring food cost percentage, restaurant owners can know when to change menu prices, look for new suppliers, or even switch up their menu entirely to stay profitable. While doing this requires a certain amount of work, it is critical to your success as a restauranteur.

How Can I Figure Out My Food Cost Percentage?

Calculating food cost percentage isn’t difficult. However, it can be a bit time-consuming, as you gather information related to your expenses, break down those expenses into individual servings, and put together data on your sales.  To get started, you will need three things:

  1. Inventory cost, including both the value of your inventory at the beginning of the week and at the value at the end of the week
  2. Purchases made during the week
  3. Total food sales

The Food Cost Formula

food cost percentage formula

You can calculate food cost percentage by using this simple food cost formula:

Food Cost Percentage = (Beginning Inventory + Purchases – Ending Inventory) / Sales

To calculate food cost percentage, add the value of the inventory at the beginning of the week to the value of your purchases made during the week. Then subtract the value of your inventory at the end of the week. This number — your food costs — is then divided by your total food sales. We’ve created a free food cost calculator you can use below, so that you don’t have to run these calculations by hand.

Calculate Your Food Cost Percentage

Enter the total dollar value of your food supplies available at the beginning of the period.

Enter the dollar value of food supplies you purchased during the period.

Enter the total dollar value of your food supplies available at the end of the period.

Enter in your total sales for the period.

Food Cost Percentage


For example, if you have a beginning inventory value of $15,000 at the start of the week, made $3,000 in purchases throughout the week, and had an ending inventory value of $12,000, your food costs were $6,000 ($15,000 + $3,000 – $12,000 = $6,000). If your total food sales were $14,000, then your food cost percentage is 42.85% ($6,000 divided by 14,000 = 0.4285). This means that 42.85% of your total revenue went towards paying for ingredients, which is higher than average.

For many restaurants, a food cost percentage of 42.85% is too high. There are a number of ways that this hypothetical restaurant can cut costs and reduce their actual food cost percentage to meet their ideal food cost percentage.

For example, if the restaurant’s food costs went up due to waste in the kitchen, the owner could work with the chef and staff to reduce costs associated with spoiled foods or throwing too many ingredients away.

Calculating Ideal Food Cost Percentage

The actual food cost formula accounts for theft and waste by factoring in your ending and starting inventory. In an ideal world, there would be no theft or food waste. If you’re working to eliminate food theft and waste, you can calculate your ideal food cost percentage. The ideal food cost percentage only accounts for total costs and sales for each menu item. The closer your actual food cost percentage gets to your ideal food cost percentage, the more you’ll have reduced food waste and theft.

The ideal food cost formula is as follows:

Ideal Food Cost Percentage = Total Cost Per Dish / Total Sales Per Dish

You can determine your ideal food cost percentage by dividing your total food costs for a set period of time by the total food sales for that same period. For example, if your total food costs are $3,000 and your total food sales are $8,800, then your ideal food cost is 0.34, or 34%.

Once you know your ideal food percentage, you can use this number to set menu prices — and to reconfigure them as necessary. Consider a restaurant that sells a turkey club sandwich with fries for $12.99. The cost per serving of this $4.75. When you divide $4.75 by 0.34 (the ideal cost percentage for this restaurant), you get $13.97. This menu item is underpriced, and currently represents a food cost of 36.5%. Pricing it at $13.99 will ensure that the restaurant stays on track financially.

Going through your menu to determine the food cost per serving and determining whether it meets your ideal food cost percentage may seem tedious. But in the restaurant business, where every penny counts, it is vital to your success.

How To Decrease Your Food Cost Percentage

There are several things you can do to reduce your food cost percentage if your percentage is too high.

  • Add more carbs to the menu: Carbs are more filling than protein or fat and they tend to be cheaper than other ingredients. You can buy carbs like pasta and potatoes in bulk at very affordable prices.
  • Raise menu prices: Has it been a while since you’ve raised your menu prices? It could be time to revisit your prices and consider raising prices to match rising costs. Raising menu prices is the easiest way to decrease your food cost percentage.
  • Shop for new ingredient vendors: Vendors change pricing all the time. Shopping for vendors is a never-ending cycle. You may have gotten the best price on tomatoes a year ago with your current vendor, but that may no longer be the case today. Occasionally reach out to new vendors for quotes to work on reducing your inventory costs.
  • Keep portion sizes under control: Your prices are based on specific portions of food. It’s important to make sure staff is providing food portions that match what you’ve priced into the menu. If dishes are constantly being returned with large quantities of leftovers, or customers are frequently requesting boxes to take food home, it could be a sign that your portions may be too large and can be reduced. Smaller portions means less inventory used, which helps to decrease your food cost percentage.
  • Reduce free items: Many restaurants will provide free baskets of bread or chips to guests. These free items will raise your food cost percentage. You don’t necessarily have to eliminate these free items, but you can place a limit of one free basket per table instead of offering unlimited free refills.
  • Change your menu to match the season: Ingredients that are in-season tend to cost less than ingredients that are out-of-season. Changing your menu every season to feature seasonal ingredients can save you money and reduce your food cost percentage.

While food costs are one of your largest expenses, food isn’t your only expense. Keep in mind that there may be other ways to cut costs and increase profitability if you feel you’ve done all that you can with your food costs.
