Inventory Valuation

Inventory valuation is the method used to assign a monetary value to the stock a business holds at a particular date. In a restaurant, inventory is commonly valued at cost using a consistent method, so the business can calculate food cost, report stock value and compare financial results between periods.

Common inventory valuation methods

• FIFO (first in, first out): assumes the earliest purchased inventory is used or sold first. This method often reflects the physical rotation of perishable food.
• Weighted average cost: calculates an average unit cost from the quantity and cost of inventory available during the period.
• Specific identification: assigns the actual cost to individually identifiable items or lots, where practical and appropriate.

How inventory value is calculated

For a basic stock count, multiply the quantity on hand by the applicable unit cost, then total the value across all items. The unit cost should be calculated consistently under the business’s accounting policy. Pack-size conversions, partial cases, transfers and supplier credits must be handled accurately.

Example in a restaurant

If a kitchen has 10 kg of beef on hand and the applicable inventory cost is $18 per kilogram, the recorded value is $180. If the business uses weighted average cost, the $18 figure should reflect the weighted average purchase cost under its chosen method, not simply the latest price unless that is the approved method.

Inventory valuation versus physical inventory

Physical inventory is the count of stock actually on hand. Inventory valuation assigns a cost to that stock. Accurate valuation requires both reliable quantities and consistent unit costs.

Why valuation matters

Inventory valuation affects the balance sheet and the calculation of cost of goods used or sold. Businesses should follow the applicable accounting standards and use the same method consistently unless a change is justified and properly documented.

Chef’s tip: standardize units of measure and count procedures. A correct quantity multiplied by an incorrect pack cost can still produce a misleading inventory value.
