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.

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.

Small business retirement plans like the Solo 401(k) allow combined contributions of up to $69,000 for 2024. Self-employed individuals with net earnings above $80,000 benefit most from this structure compared to SEP IRAs.
