But leveling up your leadership skills does not come cheap. For example, a top-ranked executive MBA can cost over $250k, and even less intensive executive leadership programs can cost several thousands of dollars.

That said, leadership training has a decent return on investment (ROI). According to a Training Industry study by ROI expert Paul Leone, first-time managers who complete a leadership development program offered a 415% annualized ROI, meaning that their respective companies made $4.15 for every $1 spent on the skills training. 

The study also found that the sooner leaders participated in training, the more value added to an organization’s bottom line.

So, if leadership training interests you, but you want to start out with something more affordable, Fortune has compiled 10 free leadership courses from top-ranked universities, sorted alphabetically—all of which can be a great place to start.
