Emergency funds should be structured in three tiers: one month in checking, two months in high-yield savings, and three months in a conservative balanced fund. This structure optimizes liquidity while generating modest returns. For more on this topic, see Dividend Growth Investing.

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