Inventory Turnover
Inventory turnover measures how many times your restaurant completely cycles through its food inventory during a given period. A higher turnover rate means you are using ingredients quickly and replacing them with fresh stock. A lower rate means food is sitting in storage longer, increasing the risk of waste and spoilage.
Why it matters for your restaurant
Restaurants work with perishable products. Unlike a retail store where inventory can sit on a shelf for months, your ingredients have a limited window before they lose quality or become unsafe. Inventory turnover tells you whether you are buying the right amounts at the right frequency.
A healthy inventory turnover for a restaurant is typically between 4 and 8 times per month, meaning you cycle through your entire inventory roughly every 4 to 7 days. If your turnover is lower, you are likely holding too much stock, tying up cash in ingredients that might spoil before they get used. If it is unusually high, you might be ordering too frequently and risking stockouts that lead to 86'd items during service.
How it works in practice
Calculate inventory turnover by dividing your COGS for the period by your average inventory value. If your monthly COGS is $24,000 and your average inventory (beginning plus ending divided by two) is $4,000, your turnover is 6. That means you go through your entire inventory about six times per month, or roughly every five days.
Say you run the numbers and discover your turnover is only 3, meaning your inventory sits for about 10 days before being used up. That is a red flag for a restaurant. You likely have produce wilting in the walk-in, proteins approaching their use-by dates, and cash tied up in food that is not generating revenue yet.
To improve turnover, start by identifying slow-moving items. That specialty cheese you bought three weeks ago that has only been used in eight dishes? Either feature it more prominently or stop ordering it. Tighten your ordering schedule so deliveries come more frequently in smaller quantities. Use your prep list and sales forecasts to buy what you actually need rather than stocking "just in case."
Connecting the dots
Inventory turnover ties directly to your food cost and cash flow. Faster turnover means fresher food, less waste, and more available cash. It also means your menu reflects what you are actually buying and using, which creates a healthier, more efficient kitchen operation overall.
