Inventory to Sales Ratio

Inventory to Sales Ratio– Many retail businesses have ups and downs in sales throughout the year. Analyzing sales during specific periods will help you readily identify these ebbs and flows. Once identified, calculate the inventory turnover ratios for various timeframes. During slower periods, find ways to move the stock faster and during busier times, make sure you always have enough on hand. You may be purchasing products in lower quantities than optimal, leading to higher shipping costs and perhaps out-of-stock products.

Calculating the Ratio

It is a sign of ineffective inventory management because inventory usually has a zero rate of return and high storage cost. Higher inventory turnover ratios are considered a positive indicator of effective inventory management.

What Is the Inventory Turnover Ratio?

However, the average turnover ratio of 5 might be hiding some important details. What if four items make up 40% of the company’s sales and account for only 10% of the inventory cost? This means that the remaining items in inventory will have a cost of goods sold of $3,000,000 and their average inventory cost will be $900,000. As a result, the majority of the items in inventory will have an average turnover ratio of 3.3 ($3,000,000 divided by $900,000).

The formula to use to determine inventory turnover ratio is the cost of goods sold during a period divided by the inventory on hand (ending inventory) for the period. For example, if cost of goods sold during a year is $20,000 while the inventory on hand is valued at $10,000, the inventory turnover ratio is 2. Compare the turnover ratio with the industry’s average to determine if it is high or low. For example, Derek owns a retail clothing store which sells the best designer attire. Derek worked in the apparel industry for quite a while, thus is well suited for the operations of his company.In other words, the majority of items are turning on average every 109 days (360 days divided by the turnover ratio of 3.3). That’s a significant difference from the 72 days that we first computed on the totals. Inventory turnover measures a company’s efficiency in managing its stock of goods. Moving inventory out of your warehouse and into your customers’ hands is a major objective of running a profitable business.

What is a good age of inventory?

The average of inventory is the average amount of inventory available in stock for a specific period. To calculate the average of inventory, take the current period inventory balance and add it to the prior period inventory balance. Divide the total by two to get the average inventory amount.Inventory turnover ratio explanations occur very simply through an illustration of high and low turnover ratios. Despite this, many businesses do not survive due to issues with inventory. A low inventory turnover ratio shows that a company may be overstocking or deficiencies in the product line or marketing effort.

You need somewhat of an expert because the matter is more complicated than the abilities simple, web-based inventory turnover ratio calculator.The faster your inventory sells, the quicker you recoup your purchase costs and earn a profit.

How to Calculate the Inventory Turnover Ratio

Robin Cooper and Robert S. Kaplan, proponents of the Balanced Scorecard, brought notice to these concepts in a number of articles published in Harvard Business Review beginning in 1988. Cooper and Kaplan described ABC as an approach to solve the problems of traditional cost management systems. These traditional costing systems are often unable to determine accurately the actual costs of production and of the costs of related services. Consequently, managers were making decisions based on inaccurate data especially where there are multiple products. These ratios can be compared with peers in the same industry and can identify businesses that are better managed relative to the others.

How do you calculate average inventory?

Average inventory is the mean value of an inventory within a certain time period, which may vary from the median value of the same data set, and is computed by averaging the starting and ending inventory values over a specified period.The inventory turnover ratio is an efficiency ratio that shows how effectively inventory is managed by comparing cost of goods sold with average inventory for a period. This measures how many times average inventory is “turned” or sold during a period. In other words, it measures how many times a company sold its total average inventory dollar amount during the year. A company with $1,000 of average inventory and sales of $10,000 effectively sold its 10 times over.


If the company can’t sell these greater amounts of inventory, it will incur storage costs and otherholding costs. According to your annual financial statements and accounting records, your cost of goods sold is $60,000 and the ending inventory is $20,000. After dividing $20,000 into $60,000, your inventory turnover ratio is three.

Understanding Average Inventory

However, a higher inventory turnover ratio does not always mean better performance. It sometimes may indicate inadequate inventory level, which may result in decrease in sales.

The Formula for Average Inventory Is:

People within the company can overcome the shortcomings described above, since they have access to all of the sales and inventory detail. A computer generated report can compute the inventory turnover ratio and the days’ sales in inventory for each and every item sold and/or held in inventory. By reviewing each item, the slow moving items will not be hidden behind an average. One limitation of the inventory turnover ratio is that it tells you the average number of times per year that a company’s inventory has been sold. A turnover ratio of 5 indicates that on average the inventory had turned over every 72 or 73 days (360 or 365 days per year divided by the turnover of 5).Some common efficiency ratios are accounts receivable turnover, fixed asset turnover, sales to inventory, sales to net working capital, accounts payable to sales and stock turnover ratio. Inventory turnover is a measure of the company’s ability to flip its products for cash.To calculate inventory turnover, divide your total sales by the average inventory on hand. Average inventory is important because the value of your inventory can change dramatically at any given time, thereby not reflecting accurate data. Figuring out your stock turnover with the average inventory, therefore, will provide more reliable results. This ratio is important because total turnover depends on two main components of performance. If larger amounts of inventory are purchased during the year, the company will have to sell greater amounts of inventory to improve its turnover.
