Most investors think they’re buying the same thing when they choose a target date fund—but two people who bought 2025 target date funds 15 years ago could have 40% different returns today. Same target year, wildly different outcomes. The culprit? Fund families structure these “simple” investments in dramatically different ways, and most investors never look under the hood.
