How Much Do I Need to Retire at 50?
Published June 2026 · 5 min read
The short answer: 25 times your annual spending. But retiring at 50 means a 35-45 year retirement horizon — far longer than the standard 30 years the 4% rule was designed for. Here's exactly what you need at different spending levels.
FIRE Number by Spending Level (Age 50)
| Annual Spend | FIRE @ 4% (25x) | Safer @ 3.5% (28.5x) |
|---|---|---|
| $40,000 (Lean FIRE) | $1,000,000 | $1,140,000 |
| $60,000 (Moderate) | $1,500,000 | $1,710,000 |
| $80,000 (Comfortable) | $2,000,000 | $2,280,000 |
| $100,000 (Fat FIRE-ish) | $2,500,000 | $2,850,000 |
The Longer Retirement Problem
At 50, you could live another 40+ years. The standard 4% rule assumes a 30-year retirement. For 40+ years, many FIRE practitioners use 3.25-3.5% withdrawal rates. That means saving 28.5-31× expenses instead of 25×. The difference is significant — but so is the peace of mind.
