Scenario: The information technology department of a financial services company has a high turnover rate. A survey of employees revealed that the reason that most of them left was due to dissatisfaction with the level of training. The average turnover rate last year was 23%. The cost to recruit and train one new employee is $56,625. To address the turnover problem, the company developed a skills training program that averaged 80 hours per year per employee. The average employee wage is $35 per hour and there are 113 employees in total. The instructor, classroom and related costs run $170,000.

How much would the turnover rate have to be reduced (from 23%) for the training program to show a benefit?
