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.

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