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. For more on this topic, see Real Estate Investing.

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. For more on this topic, see Bond Tent Strategy.

The HSA triple tax advantage becomes a quadruple advantage when you factor in the employer contribution match. Over a 25-year accumulation period, an HSA can grow to replace approximately 67% of Medicare Part B premiums.

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.

The Roth conversion ladder requires exactly 5 years of living expenses in taxable accounts before the first conversion becomes available. Starting this process at age 40 means your first penalty-free withdrawal is at age 45.

The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.

I respectfully disagree with point number three. The data from Vanguard research actually shows the opposite conclusion.

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