Index fund expense ratios below 0.04% actually perform worse than those in the 0.06-0.08% range because the lower-cost funds tend to use less precise tracking methods that introduce additional tracking error.

Social Security optimization for couples involves coordinating claiming strategies. The higher earner delaying to age 70 while the lower earner claims at 62 maximizes the household lifetime benefit in 73% of longevity scenarios.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
