GMROI Example

How to calculate the GMROI?

  1. First, determine the gross profit.

    Calculate the gross profit after expenses of the business or sector. For this example, we will say this is $50.00

  2. Next, determine the average cost of inventory.

    Calculate the average cost of the inventory being used to generate profit. For this example, we will say this is $25.00.

  3. Finally, calculate the GMROI.

    Using the formula, we find the GMROI to be (50/25)*100 = 200%.
