Reporter: Gram gibson owns a chiropractic business in seattle and recently started saving for his retirement but they have no idea if their plan is getting the most bang for its buck. When you check your statement do you understand all of that verbage? No, I don't. Do you know what fees to look for? No. Do you have any idea how much you're paying in fees? No. Reporter: Like so many of us they don't know where to look. It's easier to watch the statements come in and -- the money is coming in.

Half a million dollars for one percent. That's a lot. And that's real money! Reporter:500,000 in fees is an astounding number.
