What is Raw Materials Inventory and How to Calculate It

If you’re a business that manufactures products, it’s necessary to calculate your raw materials inventory. This is essential for tracking quantities and costs and helps maintain a smooth production process. Here’s everything you need to calculate your raw materials inventory and why you should consistently monitor your inventory levels.

What is Raw Materials Inventory? 

A raw materials inventory consists of unprocessed materials gained from suppliers before using them during the production process. Typically, raw materials inventory includes items like:

  • basic commodities (e.g., metals, minerals, oil, gas, wood, and agricultural products)
  • components (e.g., resistors, capacitors, integrated circuits) 
  • Chemicals
  • Fabrics and textiles
  • Packaging materials

Why Should Small Businesses Calculate Raw Materials Inventory?

Maintaining raw materials inventory ensures a smooth production process, meeting customer demand promptly and reducing lead times. 

To effectively manage raw materials inventory, you need to track quantities, costs, reorder points, and supplier information. 

This management helps with planning production schedules, managing procurement activities, and optimizing inventory levels to minimize holding costs while avoiding stockouts. Many companies, including those in the manufacturing, construction, and food and beverages industries, will need to track their raw materials regularly.

Raw Materials Inventory Formula 

The raw materials inventory formula is simple to use. Use the following formula: 

Beginning Raw Materials Inventory = (COGS + Ending Raw Materials Inventory) – Raw Materials Inventory Purchases

Let’s look at the following example. 

Say you have 100 units of Raw Material A, which cost $10 per unit, and 200 units of Raw Material B, which cost $15 per unit.

Total Cost of Raw Material A = 100 units × $10 per unit = $1,000

Total Cost of Raw Material B = 200 units × $15 per unit = $3,000

Total Cost of Raw Materials Inventory = $1,000 + $3,000 = $4,000

How to Calculate Raw Materials Inventory

Wondering how to calculate your raw material inventory? It’s a straightforward process. Here's a step-by-step process on how to calculate raw materials inventory:

  1. Identify the raw materials by determining the types of raw materials you have in stock. Make a list of the various materials used in your production processes, such as metals, plastics, chemicals, fabrics, or packaging materials.
  2. Determine the quantity of your raw inventory by counting and recording the quantity of each raw material on hand. You can do this by conducting a physical inventory count (also known as stocktaking) or using digital inventory management systems such as QuickBooks that tracks quantities automatically.
  3. Assign unit costs by determining the cost per unit for each raw material. This calculation includes the purchase price from suppliers, shipping costs, and any other expenses you pay to acquire the materials.
  4. Multiply the quantity of each raw material by its respective unit cost to calculate the total cost of each item in inventory. This will give you the value of the raw materials on hand.
  5. Sum up the values by adding up the total values of all the raw materials to obtain the overall raw materials inventory value. This will represent the total worth of your raw materials currently in stock.

Remember to update your raw materials inventory regularly to reflect any purchases, usage, or changes in quantities. This ensures you make accurate calculations and helps you make data-driven decisions about reordering and managing your inventory effectively.
