Americans know more about Hulu, Spotify and Netflix fees than they do about those in their 401(k)s.

Yep, it’s true; the average American can tell you exactly how much they pay to stream Game of Thrones or listen to the latest Grammy winner, but has no idea how much it costs them to have a retirement account—and how much it could cost them in retirement funds down the road, when they’ll need that money to live on.

That’s according to a new TD Ameritrade survey, which finds that although 96 percent of people know how much their streaming media services cost each month, only 27 percent know how much they’re paying in fees on those 401(k)s.
