The 4% rule assumes your money runs out in 30 years. This formula solves for a corpus that never drains, from return minus inflation.
The formula-first approach is refreshing. Sequence risk still feels like the big blind spot.
Here's the TL;DR version of this:
• FIRE requires a numeric target, not vibes.
• Withdrawal, inflation, and returns define feasibility.
• Discounting future value changes outcomes.
• Age and time horizon matter materially.
• FIRE is solvable with math, not motivation.
