Updated August 10, 2026. Quick answer. Two target-date funds with the same year in their name (say, “2045”) can hold meaningfully different stock/bond mixes, because each provider sets its own glide path — the schedule for shifting from stocks to bonds as the target year approaches. The name tells you the intended retirement year; it doesn’t tell you how aggressive or conservative the fund is along the way.
The glide path is the actual product
A fund family’s glide path — its published schedule of stock/bond allocation by years to target date — is disclosed in the fund’s prospectus and fact sheet. Some providers stay more heavily in stocks closer to and even past the target date (“to” vs. “through” glide-path philosophies, in industry terms); others de-risk earlier. Neither is objectively correct, but they produce different outcomes in a downturn near your retirement date, and the fund’s own literature states which philosophy it follows.
Check the current allocation, not just the glide-path chart
The fact sheet’s current stock/bond/cash breakdown is the actual, present-day exposure — worth checking directly rather than reading a glide-path chart and assuming the fund sits exactly on the published line at every point in time.
The expense ratio still applies, and it varies more than you’d expect
Target-date funds are often treated as a “set it and forget it” default, but their expense ratios vary meaningfully across providers — some are built from low-cost index funds internally, others from higher-cost actively managed underlying funds. The fund’s total expense ratio (which may combine an underlying-fund layer and a wrapper layer) is disclosed in its prospectus.
If your plan only offers one target-date family
Most 401(k) plans offer a single target-date series, not a choice among providers — so the research question usually isn’t “which target-date fund should I pick” but “does this plan’s target-date fund’s glide path and cost match what I’d choose if I could pick freely,” and if not, whether the plan’s other core options let you build a closer match yourself.
