Calculating Food Cost Percentages in Restaurants

Listen to the podcast of the article here

Introduction

In the highly competitive restaurant industry, keeping a close eye on costs is essential for success. A crucial aspect of managing expenses is calculating food cost percentages, which can significantly impact a restaurant’s bottom line. Surprisingly, many restaurant owners need an accurate understanding of their food cost percentages; some even struggle to calculate these figures. By regularly and quickly calculating food costs, restaurant owners can make informed decisions, adapt their strategies, and better manage their resources. In this blog, we will discuss the importance of accurately calculating food cost percentages, using the example of a South African restaurant with an average monthly turnover of R1,000,000.

Why is Calculating Food Cost Percentages Important?

Food cost percentage is a key performance indicator that helps restaurant owners understand how much they spend on ingredients relative to the revenue they generate from selling menu items. This figure is critical for pricing menu items correctly, ensuring profitability, managing waste, and making informed decisions about the restaurant’s menu and operations.

Many restaurant owners are surprised to learn that they need to be calculating their food cost percentages accurately or even at all. Waiting for an accountant to provide these figures weeks later is not a viable strategy, as it leaves little time to take action and make adjustments that could impact the following month’s performance. To stay ahead of the competition and maintain a profitable business, it’s essential to calculate food cost percentages frequently and efficiently.

Effective and Accurate Means of Calculating Food Cost Percentages

To calculate food cost percentages per item in a restaurant, follow these steps:

  1. Determine the cost of each ingredient in a recipe, measured in Rands (ZAR).
  2. Add up the costs of all ingredients in the recipe to find the total cost of producing the dish.
  3. Divide the total cost of producing the dish by the selling price of the dish, and multiply by 100 to determine the food cost percentage for that item.

For example, if a dish costs R50 to produce and sells for R200, the food cost percentage for that item would be (R50 / R200) x 100 = 25%.

Calculating Monthly Food Cost Percentage

To calculate the overall monthly food cost percentage for the entire restaurant, follow these steps:

  1. Add up the total cost of all food items purchased during the month.
  2. Add up the total revenue generated from selling menu items during the month.
  3. Divide the total cost of food items by the total revenue from food sales, and multiply by 100 to determine the overall monthly food cost percentage.

For instance, if a restaurant’s total food cost for the month is R420,000 and the total food sales revenue is R1,000,000, the monthly food cost percentage would be (R420,000 / R1,000,000) x 100 = 42%.

Calculating Monthly Food Cost Percentage with Opening and Closing Stock

To account for inventory fluctuations, restaurant owners should also consider their opening and closing stock when calculating monthly food cost percentages:

  1. Calculate the total cost of food items in stock at the beginning of the month (opening stock).
  2. Add the total cost of all food items purchased during the month.
  3. Subtract the total cost of food items in stock at the end of the month (closing stock).
  4. Divide the resulting figure by the total revenue from food sales during the month, and multiply by 100 to determine the monthly food cost percentage.

For example, if a restaurant’s opening stock is R200,000, total food purchases amount to R300,000, and closing stock is R120,000, the adjusted food cost would be R200,000 + R300,000 – R120,000 = R380,000

Continuing from the previous example, with an adjusted food cost of R280,000 and total food sales revenue of R1,000,000, the monthly food cost percentage accounting for opening and closing stock would be (R380,000 / R1,000,000) x 100 = 38%.

Regularly monitoring and analysing food cost percentages is crucial for the success of any restaurant. By understanding and implementing these calculations, restaurant owners can ensure their menu items are priced appropriately, manage inventory more effectively, and maximize profitability. Moreover, this knowledge enables them to respond quickly to changes in the market, customer preferences, or operational challenges.

In conclusion, accurate and frequent calculation of food cost percentages is vital to managing a successful restaurant business. It lets owners make informed decisions, optimise their menu offerings, and minimise waste. By following the methods outlined in this blog, South African restaurant owners can efficiently calculate food cost percentages and ensure their business remains profitable and competitive in the ever-evolving food service industry.
