Expense Ratios vs. Performance in 401k I'm currently looking at rebalancing my VOYA 401k. My fund options are limited but I think I can do better than the Target Date funds for expense ratios.

I'm confused as to how the expense ratios are calculated relative to the performance data listed.

For example, the Target 2045 Fund lists an expense ratio of 1.27% and a YTD return of 5.25%. When I create my own allocation, I can get my expense ratio down to 0.9% but the YTD return of those funds comes out to 4.95%.

Am I better off seeing a 5.25% return with a 1.27% expense ratio or a 4.95% return with a 0.9% expense ratio? (I fully understand that past performance is not a clear indicator of future performance)

I have ~$130k in assets in this 401k currently.
