Key Numbers and Analysis
Traditional retirement vs. FIRE comparison across key factors
| Factor | Traditional Retirement (Age 65) | FIRE (Age 45) | Key Difference |
|---|---|---|---|
| Social Security | Full benefit available | Not yet available (20-year gap) | FIRE portfolio must bridge 20 years |
| Medicare | Available at 65 | Not available (gap of 0-20 years) | FIRE healthcare costs are private |
| Required portfolio | $500K-$800K with SS + Medicare | $1.2M-$2M without SS + Medicare | 50-100% larger portfolio needed |
| Investment horizon | 25-30 years | 40-50 years | Lower safe withdrawal rate at FIRE |

ℹ️The Healthcare Gap Is the Real FIRE Cost
The 20-year Medicare gap (FIRE at 45 to Medicare at 65) costs $168,000-$360,000 in cumulative healthcare premiums at $700-$1,500/month. This is the single largest additional cost of FIRE vs. traditional retirement.
