How the math works

Coast FIRE number = your full FI target ÷ (1 + real return)^(years to retirement). It's the amount that, left untouched, compounds to your FI target by your retirement age — so you no longer need to contribute, only cover your current expenses. The chart shows your current savings growing with no further contributions. Estimates only — not financial advice.
