What is GMROI? Gross margin return on inventory
Gross margin return on investment (GMROI) is a widely used metric for evaluating the inventory's profitability. In other words, GMROI determines how efficiently you can leverage your company's inventory for gross profit.
How can you use the GMROI index? Companies, especially retail establishments, invest much of their capital in inventory. GMROI calculation will guide you to understand whether your inventory is profitable and decide if making changes (e.g., the price and quantity adjustment of the product) may increase your margins. Keep reading to find out what a good GMROI is.
What is a good GMROI?
In general, GMROI higher than one means that the company is making a profit on inventory. Consequently, the higher the GMROI indicator is, the better. Although, as the rule of thumb, some consider a GMROI of 3.2 a good indicator for retail stores. On the other hand, GMROI lower than one means that margins are too low. If you want to improve your inventory management, be sure to implement accounting methods presented at FIFO calculator or LIFO calculator.
How to calculate GMROI
The GMROI formula is quite simple. To compute the indicator, you need to perform the following calculations:
GMROI = gross profit / average inventory cost
gross profitequals net sales minus the cost of sold goods.
average inventory costis the average of the beginning and ending inventory.
Let's bring an example of a hypothetical company, Alpha, with the following information:
- Gross profit: $150,000
- Average inventory cost: $50,000.
In this case,
$150,000 / $50,000 = $3 . This means that the business makes $3 in gross profits for every dollar spent on inventory. We can also say this company earns gross profits of 300% of the inventory costs.
