Inventory Cost Formula
Let's discuss the formula! The fundamental formula for determining inventory costs is:
Inventory cost = purchase cost + order costs + shortage costs + holding costs
Let's break it down a little further:
Purchasing Costs: This is your base cost, the amount you spend for the products themselves.
Ordering costs: Keep in mind that these are all the expenses that appear when you place an order. It's not only the product price; there are also shipping, handling, and processing fees to consider.
Shortage Costs: This is the "oops" cost, which occurs when you are unable to complete an order due to a lack of inventory. It's the potential sales you miss out on, and believe me, those can be devastating.
Holding Costs: Finally, there is the expense of maintaining inventory. These charges, which range from warehousing to insurance, might slowly drain your resources if you are not attentive.
How to Calculate Inventory Cost?
Assume you own a small e-commerce store that sells gadgets. In one month, your expenses look like this:
Purchasing costs: $2,000 (the amount you paid for the gadgets)
Ordering costs: $500 (for processing and transporting products to your warehouse).
Shortage Costs: $300 (from lost sales because some popular items were out of stock).
Holding costs: $700 (including warehousing, insurance, and depreciation).
Now, input these into our formula:
Inventory cost = $2,000 (purchasing) + $500 (ordering) + $300 (shortage) + $700 (holding) = $3,500.
Calculating your overall inventory cost allows you to know exactly where your money goes. Maybe you realize you're ordering too often and could reduce on ordering prices, or perhaps you need to locate cheaper storage alternatives to decrease your holding costs.

Methods to Calculate Inventory Cost
Different businesses, different strategies! There are various ways to determine inventory cost, and the one you choose can have a significant effect on your finances.
FIFO (First-In, First-Out): Imagine you own a sandwich business. The oldest sandwiches (or inventory) are sold first. FIFO operates in the same manner, providing that you sell your oldest inventory first. It is beneficial during periods of rising prices since it lowers the cost of items sold while increasing earnings.
- Formula for Inventory Cost: ∑(Cost of Oldest Purchases×Units Sold)+∑(Cost of Remaining Purchases×Units in Ending Inventory)
LIFO (Last-In/First-Out): Consider the reverse scenario: you're selling the newest sandwiches first. LIFO believes that the most recent inventory is sold first, which might help lower your taxable income during inflation but may leave you with old inventory.
- Formula for Inventory Cost: Inventory Cost=∑(Cost of Recent Purchases×Units Sold)+∑(Cost of Older Purchases×Units in Ending Inventory)
Weighted Average: This method takes the average cost of all items available during the period. It's similar to saying, "Let's take the average price of everything." It evens out price swings and offers a balanced approach.
- Weighted Average Cost per Unit = Total Cost of Goods Available for Sale/Total Units Available for Sale
- Inventory Cost = Weighted Average Cost per Unit×Units in Ending Inventory
How to Calculate Inventory Cost Manually?
Accurate inventory cost estimation is crucial for effective financial management and operational efficiency. Knowing how to manually calculate inventory costs enables firms to keep accurate financial records, make informed purchasing decisions, and measure profitability. To manually calculate inventory costs, follow these procedures.
Calculate the cost of goods sold (COGS): Begin by estimating the cost of products sold. This represents the total cost of the inventory sold during the period. It comprises the purchase price of the products as well as any additional expenditures associated with preparing them for sale.
Calculate the initial inventory: Determine the value of inventory on hand at the beginning of the quarter. This figure should correspond to the end of the previous accounting period.
Add Purchases: Include the cost of any additional goods purchased throughout the time. This covers direct charges for procuring the items.
Subtract Ending Inventory: Determine the value of the remaining inventory at the conclusion of the period. This can be determined using several approaches, including FIFO (First In, First Out), LIFO (Last In, First Out), and weighted average.
Calculate Inventory Cost:
Use the formula: Inventory Cost = Beginning Inventory + Purchases - Ending Inventory.
This formula calculates the cost of inventory used throughout the time.
Review and adjust: Check that all expenditures are precisely included and compensate for any differences. Regularly checking the inventory cost computation helps to ensure financial accuracy.
