This document discusses calculating the return on investment (ROI) of corporate eLearning programs. It explains that ROI is determined by comparing the monetary benefits of an eLearning system to its costs. eLearning can reduce costs associated with training by decreasing training time, travel costs, and lost productivity compared to traditional classroom training. While some costs of eLearning like content development are higher initially than classroom training, eLearning yields long-term savings and improves learner performance and retention of knowledge compared to traditional methods. The ROI of eLearning varies between organizations but typically yields substantial savings over classroom training.
