<prompt> Human: Hello. So Im trying to find out if my 401k is a good plan. It does have great options VINIX but I notice it charges me a flat administrative fee every quarter.Im new to 401k as this is my first account. Is this flat fee normal? If it is, how much is the average 401k charging people?Note: totally separate from expense ratios.  <response>: How much is the fee...?
