Fat FIRE on $200K/year — $5.71M target
FIRE number: $5,714,286 ($200,000/year × 28.6). At 7% real return saving $10,000/month from $300,000, you reach it in 20 years — age 55. Savings rate: 38%.

Frequently asked questions
What's the FIRE number for fat fire on $200k/year — $5.71m target?
FIRE number = annual expenses × (100 / SWR). For $200,000/year expenses at 3.5% SWR: $200,000 × 28.6 = $5,714,286.
How many years to reach this FIRE number?
Starting with $300,000 and saving $10,000/month at 7% real return, you reach $5,714,286 in 20 years at age 55. Total contributed in the simulation: $2,700,000; growth: $3,380,364.
What savings rate does this require?
$120,000/year saved out of an implied $320,000 income = 38% savings rate. This is an arithmetic scenario; the result changes with income, expenses, contributions, taxes, fees and return assumptions.
What if my real return is different?
Keeping this scenario's balance, expenses, contributions and 3.5% SWR fixed, a 5% real-return sensitivity reaches the target in 23 years; an 8% sensitivity reaches it in 19 years. These are constant-return illustrations, not forecasts.
How this number was calculated
FIRE number = Annual expenses × (100 / SWR)
= $200,000 × 28.6
= $5,714,286
Years to FIRE: solve bal × (1 + r) + annual_contrib = FIRE
starting bal = $300,000
annual_contrib = $120,000
r (real return) = 0.07
→ 20 years (age 55)
Total contributed = $2,700,000
From growth = $3,380,364 (59% of FIRE number)Math grounded in the Trinity Study (Cooley et al., 1998) and Karsten Jeske's SWR Series.
