Can Technology Solve the Mystery of 401(k) Fees?

As the economy improves, more Americans are changing jobs. And that means more workers leaving behind 401(k) retirement plans.

Those stranded 401(k)s create a dilemma for workers. It can be almost impossible to know whether you’re better off leaving money in an old 401(k), rolling it into a new employer’s 401(k), or rolling it over into your own individual retirement account (IRA). The problem is that figuring out 401(k) fees — the key determining factor — requires diving into oceans of fine print. Fees come in dozens of configurations, from flat annual charges to asset-based ones, and it can be exceedingly difficult to deduce whether you're getting the best deal.
