Key Data and Analysis
FIRE timeline sensitivity to annual return assumption
| Annual Return | Years to $1.2M from $100K (+ $2,000/mo) | FIRE Age from 32 | Sensitivity |
|---|---|---|---|
| 5% real | 25.4 years | 57.4 | Pessimistic |
| 6% real | 22.8 years | 54.8 | Conservative |
| 7% real | 20.6 years | 52.6 | Historical average |
| 8% real | 18.8 years | 50.8 | Moderately optimistic |
| 10% real | 15.8 years | 47.8 | Optimistic |
Every 1% difference in annual return changes the FIRE timeline by approximately 2-3 years on a $2,000/month savings rate from a $100,000 base. This is why fee reduction (0.75% → 0.03%) directly compresses the FIRE timeline.
