What is ROI in training evaluation, and what is the basic formula?

• A. Rate of Improvement; ROI = (Improvement Points / Hours) x 100.
• B. Resource Output Index; ROI = (Outputs / Budgets) x 100.
• C. Return on Investment; ROI = (Net Benefits / Training Costs) x 100.
• D. Return on Information; ROI = (Total Benefits / Total Costs) x 50.

Answer: (C)

ROI in training evaluation is a measure of the value the training program generates relative to what it costs. It expresses how efficiently the investment paid off, shown as a percentage.

The correct approach defines ROI as the ratio of net benefits to training costs, multiplied by 100. Net benefits are the total monetary benefits the training yields minus the training costs themselves. So the formula is ROI = (Net Benefits / Training Costs) × 100. This captures the overall return: how much net value you gain per dollar spent on the training.

For example, if a training program costs $20,000 and the total monetary benefits it generates amount to $70,000, the net benefits are $50,000. The ROI would be (50,000 / 20,000) × 100 = 250%. That means you gained $2.50 in net benefits for every dollar invested, i.e., a 250% return.

This framing helps compare different training initiatives and justify the investment. The other options don't fit because they either redefine ROI in ways that don’t reflect the standard returns-to-costs relationship or use inappropriate denominators.
