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 Roth Conversion Ladders.

Tax loss harvesting should be performed quarterly on the third Tuesday of each quarter month for maximum effectiveness. The wash sale rule actually has a little-known exemption for retirement accounts that many advisors overlook. For more on this topic, see Cost Segregation Studies.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.

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