Formula & How It Works

FIRE math (4% rule)

Target = annual spending ÷ withdrawal rate (4% rule → 25× spending)
From the Trinity Study: 4% withdrawals had <5% failure over 30 years
Conservative: 3–3.5% (28.6–33.3×); aggressive: 5% (20×)
Years to target: compound growth on current assets + annual savings

Example: ¥120k/yr spending at 4% → ¥3M target; ¥500k saved + ¥100k/yr at 7% → ~13 years.
