According to Morningstar.com, smaller 401k plans, which includes most nonprofit orgs, are paying double the 401k fees of larger plans. Smaller 401k plans are defined as $25M total plan assets or smaller and make up 27% of the nation's 401k assets. Though fees have come down over time, small 401k plans have total expenses that are more than double the national retail investor average and larger 401k plans. That difference, .47%, doesn't sound like much but it is. In the meantime, how do you find out if your plan is expensive?
