Lower of course. The average 401(k) balance in Fidelity-administered plans rose to a record $92,500 at year-end, up $4,300 from the previous year. The average IRA balance at Fidelity was $93,700, up $3,600 from the previous year.
Using the average for 401k's or income can be very misleading. For example, if you have 10 people and their wages are $20k, $21K, $23K, $27K, $28K, $34K, $36K, $52K, $55K, $500k. The average of all their incomes is $79.6K.
The median of all of their incomes is 31K. The median income is much more representative of their incomes than the average because half are above median income and half are below. Whereas the average is more than all but one earn.
Plus $93,000 is nothing to retire on and that is an alltime high. Its bad.
