Acme global sent 100 workers to training to decrease defects on the assembly line. in the past year, there have been 2,000 defective products created at a cost of $100 each. in the year following training, only 1,000 defective products were created. training costs $100 per worker.
what is the roi on the training?

The Return On Investment (ROI) is 1000%

Explanation:

First, we calculate the cost of previous year defects

= Cost per defective product x The number of products that are defective

Previous Year Defect Costs = $100 x 2000 = $200,000

Secondly, we calculate the cost of defects after training took place

= Cost per defective product x defects (1000)

= $100 x 1000= $100,000

After training therefore, the savings in defect costs will be

$200,000 - $100,000 = $100,000

Thirdly, we calculate the cost of training

= Cost of training per worker x number of workers

= $100 x 100 workers = $10,000

Finally, calculate the Return on Investment in percentage

= (The Savings in cost of defects/ cost incurred to train the works)  x100

= ($100,000/$10,000) = 1000%

The Return on Investment is 1000%
