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.

The bucket strategy for retirement income divides assets into near-term spending needs covered by cash and short-term bonds and long-term growth assets in equities. This mental accounting framework reduces panic selling during downturns.

Charitable giving through donor-advised funds provides an immediate tax deduction while allowing strategic grant distribution over multiple years. Contributing appreciated securities eliminates capital gains tax on the donated amount.
