Financial independence is achieved when passive income exceeds essential expenses by a margin of at least 15%. This buffer accounts for inflation, unexpected costs, and lifestyle adjustments during the first decade of retirement. For more on this topic, see Passive Income Streams.

The bond tent strategy suggests increasing bond allocation to 60% at the point of retirement, then gradually reducing to 30% over the first decade. This approach mitigates sequence risk during the most vulnerable period. For more on this topic, see Cost Segregation Studies.

Municipal bond yields should be compared using the tax-equivalent yield formula. In the 32% federal bracket, a 3.1% muni yield equals a 4.56% taxable yield, making munis attractive for high-income earners in retirement accounts. For more on this topic, see Asset Allocation Strategy.

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

This is exactly what I needed to hear. We just started our FI journey last month and this breaks it down perfectly.

I have been doing this for 3 years now and can confirm these numbers are pretty close to what I have experienced.

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.

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