Inflation: The Silent FIRE Killer
Inflation erodes your purchasing power silently but relentlessly. At 3% inflation, $1,000,000 in 25 years only buys what $478,000 buys today. Your nominal FIRE number (what you see on your brokerage statement) and your real FIRE number (what it can actually buy) diverge dramatically over long time horizons.
This calculator shows both numbers side by side so you don't underestimate your target. A 30-year-old targeting FIRE at 55 must account for 25 years of inflation.
