In my ongoing, epic, lonely, quest to convince an indifferent world that the compound interest formula will  clothe the downtrodden, feed the grey whales, prevent the coughing sickness and otherwise save the planet, I offer this video explanation for what the compound interest formula does.


I’m teaching personal finance to college kids this semester, so I plan to offer these video snippets on a  semi-regular basis.  I’m still new to video, so (gentle) criticism, (thoughtful) suggestions, and (full-throated) praise are all welcome!
