What is Total Raw Materials Available for Use?
The “total raw materials available for use” is a crucial inventory accounting figure that represents the maximum value of raw materials a company has on hand for its production process during a specific accounting period. It’s not just about what you start with; it also includes everything you acquire. Understanding this concept is fundamental for anyone looking to master inventory management and accurately assess production costs. This metric provides a clear picture of the total material assets at a company’s disposal before any production begins. For production managers and financial analysts, knowing how to calculate total raw materials available for use is the first step toward effective cost control and operational planning.
This calculation is primarily used by manufacturing companies, but it’s also relevant for any business that assembles or creates products from component parts. A common misconception is that this figure represents the materials actually used; however, it represents the *potential* materials available. To find what was actually consumed, you must subtract the ending inventory. The ability to properly calculate total raw materials available for use is a cornerstone of sound financial health for any production-based enterprise.
Total Raw Materials Available for Use Formula
The formula to determine the total materials you can use is straightforward and logical. It provides a clear path for managers who need to know how to calculate total raw materials available for use accurately.
Total Raw Materials Available for Use = Beginning Raw Materials Inventory + Raw Materials Purchases
Here’s a step-by-step breakdown of the variables involved in this essential calculation.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Beginning Raw Materials Inventory | The monetary value of raw materials in stock at the start of the accounting period. | Currency (e.g., USD) | Varies widely based on company size. |
| Raw Materials Purchases | The total cost of all raw materials bought during the same period. | Currency (e.g., USD) | Depends on production needs and supplier costs. |
By understanding these two inputs, any business can effectively determine its total potential material assets for a given period. This calculation forms the basis for further analysis, such as determining the cost of goods sold. Mastering how to calculate total raw materials available for use is non-negotiable for financial accuracy.
Practical Examples
Example 1: Furniture Manufacturer
A company, “Oak & Steel Designs,” starts the quarter with $150,000 worth of wood, steel, and fabric. Over the quarter, they purchase an additional $70,000 in materials. Using the formula, we can determine their material availability.
- Beginning Inventory: $150,000
- Purchases: $70,000
- Total Raw Materials Available for Use: $150,000 + $70,000 = $220,000
This $220,000 figure tells the production manager the total value of materials they can draw from for the quarter’s production runs. This is the primary output when you calculate total raw materials available for use.
Example 2: Small Bakery
A local bakery, “The Flour Mill,” begins the month with $5,000 in flour, sugar, and butter. Due to a large catering order, they buy an additional $8,000 of ingredients.
- Beginning Inventory: $5,000
- Purchases: $8,000
- Total Raw Materials Available for Use: $5,000 + $8,000 = $13,000
The bakery owner now knows she has $13,000 worth of ingredients available to meet her production demand. This knowledge, derived from knowing how to calculate total raw materials available for use, is critical for budgeting and pricing her products correctly. For more complex inventory scenarios, a inventory accounting guide can be very helpful.

Key Factors That Affect Raw Materials Calculations
Several factors can influence the final numbers when you calculate total raw materials available for use. Awareness of these elements is crucial for accurate financial planning and inventory control.
-
1. Supplier Pricing and Discounts
- The cost of your purchases can fluctuate significantly based on supplier prices, bulk discounts, and shipping fees. A new deal with a supplier can lower your “Purchases” cost, directly impacting the total available materials calculation.
-
2. Spoilage and Waste
- Materials that spoil or become obsolete must be written off and are not part of the ending inventory, which increases the “Cost of Materials Used.” Proper storage and handling are vital. Check out our guide on lean manufacturing principles to minimize waste.
-
3. Production Volume
- Higher production volumes will consume more materials, leading to a lower ending inventory. This directly impacts how much you need to purchase in the next period to maintain a healthy level of total raw materials available for use.
-
4. Supply Chain Disruptions
- Delays or shortages in the supply chain can limit your ability to purchase new materials, reducing the total available figure and potentially halting production. Accurate forecasting can help mitigate these risks.
-
5. Inventory Accounting Method
- Methods like FIFO (First-In, First-Out) or LIFO (Last-In, First-Out) affect the valuation of your ending inventory, which in turn alters the calculated “Cost of Materials Used.” This is a key concept covered in our guide to the balance sheet.
-
6. Economic Order Quantity (EOQ)
- Using an optimized purchasing strategy, such as that determined by an economic order quantity calculator, ensures you purchase materials in the most cost-effective amounts, influencing the “Purchases” part of the main formula.
Frequently Asked Questions (FAQ)
What is the difference between “raw materials available for use” and “raw materials used”?
“Available for use” is the total pool of materials (Beginning Inventory + Purchases). “Raw materials used” is what was actually consumed in production, calculated as (Beginning Inventory + Purchases – Ending Inventory). Our calculator shows both metrics for a complete overview.
Are direct and indirect materials included in this calculation?
Yes, both can be included. Direct materials are part of the final product (e.g., wood for a chair), while indirect materials are used in the process (e.g., sandpaper). Your accounting policy will determine how you categorize and track them, but their costs are part of the total raw materials available for use.
How often should I calculate total raw materials available for use?
This should align with your accounting periods, which could be monthly, quarterly, or annually. For operational purposes, more frequent tracking (even weekly) can provide better control over inventory and production, which is a core tenet of good a manufacturing overhead strategy.
Why is my ending inventory important for this calculation?
While ending inventory doesn’t change the “total available” figure, it’s essential for determining the Cost of Materials Used, a key component of the Cost of Goods Sold (COGS). Knowing this helps you understand your production efficiency.
Can this calculation result in a negative number?
The “total raw materials available for use” should never be negative, as it’s a sum of existing and purchased assets. However, the “Cost of Materials Used” could theoretically be negative if ending inventory is incorrectly valued higher than the total available materials, indicating a significant accounting error.
How does this relate to Work-in-Process (WIP) inventory?
Once raw materials are moved to the production floor, their cost is transferred from the Raw Materials Inventory account to the Work-in-Process (WIP) Inventory account. The “Cost of Materials Used” represents this transfer.
What’s the best way to track my raw materials inventory?
Using a perpetual inventory system with real-time tracking is ideal. This can be done with inventory management software, which automates the process and reduces manual errors, ensuring you always know how to calculate total raw materials available for use accurately.
Does the cost include shipping and storage?
Yes, according to proper accounting principles, the cost of raw materials should include all expenses to get them ready for use, which includes freight, import duties, and storage costs. This gives a true picture of your investment in the materials.
