Why our allocations use only index funds

The actively managed funds in this plan cost more per year than the plan's index funds, which run roughly 0.02% to 0.06%. Decades of research on long-term active fund performance do not support reliable outperformance net of fees, which is why the allocation ideas below may consider using only the low-cost index options.

Invested over 20 years at a hypothetical 7% annual return, that forgone match could have grown to roughly -- (a hypothetical illustration, not a projection). The match is the highest-return contribution you will make all year.
