Did you know that U.S. restaurants waste approximately $162 billion in food every year due to inefficient inventory management?
The figure is huge, and it stresses the importance of mastering inventory practices to not only reduce waste but also to improve profit margins without sacrificing customer satisfaction. However, restaurant inventory management is not a cakewalk. Implementing a robust restaurant inventory management system is crucial for proper inventory management. Effective food inventory management ensures accurate restaurant inventory and helps in calculating the average inventory turnover ratio. Managing sitting inventory and utilizing insights from food inventory data can significantly enhance overall performance.
You need to understand and use the inventory turnover ratio to your advantage like a pro. When you master this ratio, you bypass common pitfalls such as spoilage and lost sales, directly impacting a restaurant’s bottom line.
In this article, we’ll learn how much inventory a restaurant should carry to balance overstocking and understocking the kitchen. We will also explore different strategies to optimize inventory turnover for a more efficient and profitable operation. Before diving deeper, let’s start with the basics.
The Cost of Confusion
Inventory management is not rocket science. But if you can’t figure it out soon, either your kitchen might hold excess items that block your space and capital, or you might run out of ingredients to meet your customers’ special orders. Effective restaurant inventory management software helps in streamlining the entire inventory management process, ensuring that food and beverage operations run smoothly. Proper management of food cost is crucial to avoid a low inventory turnover ratio. Regularly counting inventory and adjusting accordingly can prevent issues related to excess stock and food and beverage shortages.
Let’s understand the possibility of such scenarios in detail.
1. Overstocking:
When your kitchen store holds excess inventory, it ties up your capital, which could have been used elsewhere in the restaurant business. Excess inventory calls for additional storage, and there is a chance of spoilage, especially for perishable items. Understanding the restaurant industry average for inventory counts and inventory values can help prevent having too much food on hand. Properly managing inventory process and knowing how much food inventory is needed are crucial to avoid unnecessary costs and inefficiencies.
For instance, imagine you’re overstocked on perishable fruits for tarts, but there is a low demand in the market this week. Now, they are tying up capital and risking spoilage. If it happens with regard to all items in the kitchen, you might face low cash reserves and even be unable to respond to unexpected needs and opportunities. You can easily avoid such situations with calculated inventory management.
2. Understocking
On the other hand, when you run out of items in your kitchen to meet customer demand, you might face customer dissatisfaction. Imagine a customer who has decided to dine at your restaurant with family, and they’re all excited to try your famous seafood pasta. However, soon, they get disappointed to find out you ran out of fresh seafood due to understocking. You just lost potential repeat customers who might leave negative reviews online to vent their frustration.
This necessitates restaurants managing their inventory with a balance between supply and demand to prevent shortages or wastages. That’s where it becomes necessary to learn inventory ratio to make data-driven decisions about purchasing and pricing strategies.
The Inventory Balancing Act
In simple terms, the inventory turnover ratio shows how many times a restaurant refreshes its inventory during a certain period of time. It’s typically calculated over a year, quarterly, monthly, and even weekly.
What does it measure?
It shows how quickly a restaurant cycles up its inventory.
How to calculate?
Inventory turnover ratio = Cost of goods sold (COGS) / Average inventory
Here is how to calculate the average inventory for some time (annual, monthly, or weekly)
Average inventory = (begining inventory + ending inventory) / 2
FYI,
Beginning inventory = the inventory value at the start of the period
Ending inventory = the inventory value at the end of the period
For instance, your restaurant had a beginning inventory of $2,000 at the start of the month and an ending inventory of $1,500 at the month’s end. The monthly COGS turned out to be $8,750.
Average inventory = ($2000 + $1500)/2 = $1,750
Inventory turnover ratio = $8,750/$1,750 = 5
That means you sold out your entire food or beverage inventory five times in the last month. Simply put, you stock six days of inventory on average (5 to 6 days of products on hand). Typically, five is the industry average when it comes to inventory turnover.
Why does the score matter?
If your restaurant turnover is near to or just more than the average, you are efficiently using your inventory. You might rarely face the risk of spoilage and overstocking.
A too-low score may indicate any of the following scenarios:
Stockouts
Menu restrictions
Operational inefficiency
High delivery or purchasing costs
A too-high score may indicate any of the following scenarios:
Food waste
Storage issue
Inaccurate demand forecasting
To control the inventory turnover ratio, you need to control the factors that influence it in the first place.
Finding Your Ideal Inventory Levels

Inventory levels might fluctuate and it’s a function of a lot of factors. Let’s take a look at three major factors that affect the most.
1. Sales volume
Your average sales volume over a week or month decides how much inventory you need for the next period. More sales means more inventory- simple math. If sales go down than the expected figure, restaurants may end up with too much inventory – extra storage costs and a high risk of waste.
That’s where demand forecasting comes into the picture. It requires analysing past sales data, factoring in seasonal variations, trends, and promotional offers that are going to take place in the near future.
On special occasions or holidays, sales volume might go up than normal. Restaurants need to plan for such events in advance with special menu items to attract more footfall. This means developing flexibility to manage inventory to meet seasonal fluctuations.
That’s why restaurants maintain a good relationship with suppliers to place emergency orders to meet unexpected sales on special occasions. It is also important to have more than one supplier for high-turnover items to prevent stockouts when one of the suppliers defaults.
2. Menu Complexity
If your restaurant menu spans seven pages with a wide variety of items to attract customers of different appetites, you need a robust inventory management system to avoid custom dissatisfaction due to stockout items.
The more items you have on the menu, the harder it becomes to track the inventory.
Menu engineering is one of the best ways to deal with this challenge and reduce the variety of inventory. You can also design menus that feature items requiring similar ingredients. For instance, you can maximize your chicken menu to offer chicken 65, chicken BBQ, chicken fingers, chicken burger, and chicken salad without minimizing inventory variety.
3. Delivery Lead Times
We understand why a good supplier relationship is important. But what if your supplier delivers once every two weeks? You need to hold more inventory to avoid running out of key ingredients between deliveries. Imagine if your supplier further delays the supply of items that can not be sourced locally on short notice. You may find your entire operations at stake due to a stockout.
You might assume ordering in bulk could help in such situations. However, it’s not easy to maintain large buffer stocks to compensate for longer delivery lead times. The holding costs go up, and operations run smoothly until there is no supply chain disruption.
That’s why popular restaurants put so much effort into analyzing account delivery lead times to avoid such situations. They also consider common reasons for potential delays to make dynamic changes to their order to avoid running low on popular items.
Good Thumb of Rule for Inventory Turnovers
Let’s examine some general rules of thumb for inventory turnovers for various restaurant items.
1. Food items
Turnover rate: 4-6 times per month
Guideline: should keep about 5-7 days’ worth of product on hand
Rationale: periodically rate the freshness level of food items (especially perishable items) to avoid spoilage
2. Liquor
Turnover rate: once per month
Guideline: may vary based on the sales mix of a restaurant
Rationale: longer shelf life allows less frequent turnover without the risk of spoilage
3. Bottled beer
Turnover rate: 2-3 times per month
Guideline: may be adjusted based on popularity and variety
Rationale: longer shelf life, but restaurants should focus on managing only popular varieties with good turnover rates to ensure freshness and customer satisfaction
4. Draft beer
Turnover rate: 1-2 times per month
Guideline: could vary depending on the restaurant concept and the number of beers on tap
Rationale: requires careful handling to retain freshness
5. Wine
Turnover rate: approximately once per month
Guideline: varies based on the size and your sales mix
Rationale: could be stored for longer periods, but turnover should be managed to balance variety, space, and capital investment
Beyond the Kitchen: Bar Inventory Management
There are approximately 6,60,755 bars in the US, and the drinks market is projected to grow by 1.48% by 2029. These figures clearly state the importance of learning basic bar inventory management skills for restaurants to grow and thrive.

First in, First out (FIFO)
Apply the FIFO method to manage inventory. FIFO stands for first in, first out. Use the older stock before the newer stock, especially for ingredients with an expiry date.
Active licensing
