Inventory Analysis

Inventory analysis is an evaluation of inventory performance to determine the right amount to maintain profitability. By analyzing data, a business can assess where improvements can be made in production and/or stock levels to meet demand while minimizing cash tied up in inventory.​

Each business must compare product performance to its sales goals to determine whether stock levels are delivering optimal performance.  Some common performance indicators include turnover, write-offs, average inventory, and number of days to sell. Different categories of products may perform differently depending on seasonal variations or popularity. Having access to timely and accurate data showing costs, sales, and profits will help management in setting optimal stock levels. Products may be allocated to certain categories and evaluated based on the performance of those categories, i.e. top sellers will have a different set of criteria than products that slower moving items. The goal is to satisfy demand while minimizing dead stock or spoilage while minimizing the cash invested. There are many inventory analysis methods; the ones you use may depend on your industry.

There are five different inventory analysis methods you can use:

  1. ABC Inventory Analysis – When you classify different products according to their profitability, you can determine which to prioritize in your inventory. Higher priced items may account for a small percentage of your inventory yet yield the highest profits.
  2. FSN Analysis – When you sort inventory by the speed of its turnover, you indicate which are fast moving (F), slow moving (S) and non-moving (N).
  3. VED Analysis – VED stands for Vital, Essential, and Desirable. You may have some inventory that you cannot go without, and it will be labeled Vital, but the Desirable may not sell regularly so they are ordered less frequently.
  4. HML Analysis – When inventory is sorted by cost, it is labeled high, medium or low cost inventory.
  5. SDE Analysis – This method sorts inventory by its availability labeling those items that are with long lead times as scarce, difficult to come by as difficult, and easy to acquire as easily.

These are simply different methods of sorting and labeling items to provide additional information for analysis.


The basic principal of inventory analysis involves examining past performance to predict future trends. Based on those observations, a company can determine if it will need more or less of a product to meet future demand. Part of that picture is painted by the inventory turnover, a percentage that indicates how often inventory has been sold and replaced. Usually, this will be reviewed over a long time period to balance periods of high and low fluctuation. Analysis tends to reveal best sellers and under performers and allows the business owner to plan and act accordingly. If a product does not perform well, that product’s production may be scaled back to allow greater focus on the money makers.

Dead Stock

Sometimes finished goods don’t sell. Sometimes products break or spoil. Depending on the industry, these losses may be handled in different ways. Food products, chemicals and medications may be discarded post-expiration or spoilage. Other types of products may sit on the shelves collecting dust because they went out of style or demand has decreased. A discount may be necessary to move them. In either case, the business may have to write off the loss and modify inventory counts. If your balance sheet is showing these products as having their full value, your numbers will be incorrect, overstating profits and potentially impacting tax paid.


The cost of production from start to finish includes labor, materials, and storage. The longer a product sits on a shelf, the higher its storage cost. Looking at this cumulative cost over time indicates which products are most profitable and which are not selling well.

Average Inventory

inventory analysisWhen inventory over a period of time is totaled and divided by the number of periods evaluated, the result is an average amount of inventory, that being the median between the high and lows throughout that same period.
