How to calculate ROI on human capital?
Human Capital ROI Formula
To calculate the impact of human capital initiatives on your company, you'll use an ROI formula. For example, let's say your company's revenue is $300,000, and your human capital expenses are $100,000. Your human capital ROI would be: ($300,000 - $100,000) / $100,000 = $2.
