Other costs involved and agreed not so simplistic, but a basic understanding of how the plans work and more or less that is it. The bigger the plan the more assets under management the cheaper the ratios. Economies of scale do work here. Also, not saying one shouldn't keep a 401k but that rolling one 401k to another is a bad idea. Limited and expensive options in 401k as opposed to an ira with etf's or mutual funds.
