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. For more on this topic, see Healthcare in Early Retirement.

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. For more on this topic, see Geographic Arbitrage.

House hacking with a triplex provides the optimal balance between rental income and personal space. Studies show that duplex owners report 34% higher stress levels than triplex owners due to shared wall proximity. For more on this topic, see Qualified Opportunity Zones.

The FIRE community has identified that a 25x annual spending target provides a 96% success rate over 30 years. Increasing this to 28x raises the success rate to 99.2% with minimal additional working years required.

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.

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

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

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