Restaurant Inventory Turnover: How Much Inventory Should You Carry?

Restaurant inventory turnover shows how quickly your restaurant uses and replaces the food and beverage inventory sitting on the shelves, in the walk-in and behind the bar.

Carry too little inventory and you risk running out of important products. Carry too much and cash that could be paying payroll, rent or vendors sits trapped in boxes, bottles and cases.

What Is Restaurant Inventory Turnover?

Inventory turnover measures how many times a restaurant uses and replaces its average inventory during a given period.

A higher turnover generally means the restaurant is moving inventory more quickly. A lower turnover generally means more product is sitting in stock.

Neither number should be judged by itself. The right turnover depends on concept, delivery frequency, menu, storage capacity and product mix.

How to Calculate Average Inventory

For a simple period calculation, average inventory can be estimated using beginning and ending inventory.

More accurately:

How to Calculate Restaurant Inventory Turnover

Suppose the restaurant generated $60,000 in food and beverage COGS during the month and carried an average inventory of $20,000.

That means the restaurant used the equivalent of its average inventory approximately three times during the month.

Inventory Turnover Can Also Be Measured in Days

Many restaurant operators find days of inventory easier to understand than turnover.

If monthly turnover is 3.0:

In simplified terms, the restaurant is carrying approximately ten days of product at its current usage rate.

How Much Inventory Should a Restaurant Carry?

There is no single correct inventory amount for every restaurant.

The right amount depends on several operational factors:

• How often vendors deliver
• Minimum order requirements
• Storage capacity
• Menu size
• Sales volume
• Seasonality
• Product shelf life
• Delivery reliability
• Special events
• Emergency backup needs

Why Too Much Inventory Hurts Cash Flow

Excess inventory is easy to overlook because the product is still physically present.

But the restaurant has already paid—or will soon have to pay—for that product.

Suppose a restaurant normally needs $15,000 of inventory but routinely carries $25,000.

That $10,000 is not necessarily lost. But it is unavailable for other business needs while it sits in inventory.

Excess Inventory Also Increases Waste Risk

More inventory usually means more exposure to:

• Spoilage
• Expiration
• Breakage
• Overproduction
• Obsolete menu items
• Products getting buried in storage
• Unnoticed theft or shrinkage

Fresh and perishable products are particularly sensitive to slow turnover.

Low Inventory Turnover Can Reveal Purchasing Problems

When turnover falls, the first question should not always be whether sales are weak.

Purchasing may simply be too aggressive.

Vendor Discounts Can Create Too Much Inventory

Buying extra product because the unit price is lower can seem like an easy way to save money.

But the discount only creates savings if the product is eventually used profitably.

Before buying extra inventory, consider shelf life, storage space, expected usage and the cash being committed to the order.

Inventory Turnover Should Be Reviewed by Category

One total restaurant turnover number can hide important differences.

Look for Slow-Moving Inventory

A restaurant may have acceptable overall inventory while still carrying individual items that barely move.

Review products with:

• No recent sales
• Very low usage
• Large quantities on hand
• High unit cost
• Repeated spoilage
• Menu items that were discontinued

Slow-moving items should be reviewed before the restaurant automatically orders more.

Par Levels Should Follow Actual Usage

A par level is the target quantity the restaurant wants available to support expected demand.

But pars should not become permanent simply because somebody set them years ago.

Better pars consider:

• Average daily usage
• Days until next delivery
• Expected sales changes
• Safety stock
• Existing open orders

Inventory Turnover and Restaurant COGS Work Together

Inventory turnover depends on accurate COGS.

If inventory counts are wrong, both COGS and inventory turnover become unreliable.

Read our Restaurant COGS Guide for a deeper explanation of inventory, purchases and cost of goods sold.

Inventory Variance Can Distort Turnover

A restaurant may appear to be using inventory quickly because product is disappearing faster than expected.

That does not necessarily mean strong sales.

Actual usage can exceed theoretical usage because of:

• Waste
• Overportioning
• Unrecorded comps
• Receiving errors
• Bad counts
• Theft or shrinkage

Review our guide to Restaurant Inventory Variance when inventory usage does not match what sales should have consumed.

Inventory Turnover Can Explain Cash-Flow Problems

A restaurant can be profitable on its P&L and still struggle with cash.

One reason is that cash can move into inventory faster than the inventory turns back into sales.

The longer that cycle takes, the longer the restaurant waits to recover the cash invested in product.

How to Improve Restaurant Inventory Turnover

Improving turnover does not mean ordering dangerously low quantities.

The goal is to remove unnecessary stock while protecting service.

1. Count inventory consistently.
2. Calculate actual COGS.
3. Calculate average inventory.
4. Measure turnover and days on hand.
5. Identify slow-moving products.
6. Review current par levels.
7. Compare purchasing with actual usage.
8. Reduce unnecessary safety stock.
9. Use vendor delivery frequency to your advantage.
10. Monitor waste and inventory variance.

Don't Improve Turnover by Creating Stockouts

Inventory efficiency has a limit.

Running out of a high-selling product can cost more than carrying a reasonable amount of safety inventory.

How Often Should Restaurants Review Inventory Turnover?

Monthly turnover is useful for financial reporting, but restaurants with significant inventory investment should review inventory more frequently.

Weekly inventory counts can help management see whether product levels are increasing faster than sales.

Category-level reviews can be even more useful for high-cost areas such as proteins, liquor, wine and specialty items.

Turn Excess Inventory Into a Dollar Decision

When inventory feels high, quantify it.

Suppose average inventory is currently $30,000, but the operation can safely function at $22,000.

Reducing unnecessary inventory does not create profit by itself, but it can free cash that was previously trapped on shelves.
