partners earn the median income each year over their working lifetimes, will
pay an average of $154,794 in 401(k) fees and lost returns, according to the
fee model in “The Retirement Savings Drain,” by the research group Demos. A
higher-income dual-earner household, in which the partners earn incomes greater

average, fees eat up more than a third of the total returns earned by mutual
Smaller 401(k) plans have higher
