Retire at 50 starting at age 30
FIRE number: $1,250,000 ($50,000/year × 25.0). At 7% real return saving $2,500/month from $50,000, you reach it in 19 years — age 49. Savings rate: 38%.

Frequently asked questions
What's the FIRE number for retire at 50 starting at age 30?
FIRE number = annual expenses × (100 / SWR). For $50,000/year expenses at 4% SWR: $50,000 × 25.0 = $1,250,000.
How many years to reach this FIRE number?
Starting with $50,000 and saving $2,500/month at 7% real return, you reach $1,250,000 in 19 years at age 49. Total contributed in the simulation: $620,000; growth: $682,195.
What savings rate does this require?
$30,000/year saved out of an implied $80,000 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 4% SWR fixed, a 5% real-return sensitivity reaches the target in 22 years; an 8% sensitivity reaches it in 18 years. These are constant-return illustrations, not forecasts.
How this number was calculated
FIRE number = Annual expenses × (100 / SWR)
= $50,000 × 25.0
= $1,250,000
Years to FIRE: solve bal × (1 + r) + annual_contrib = FIRE
starting bal = $50,000
annual_contrib = $30,000
r (real return) = 0.07
→ 19 years (age 49)
Total contributed = $620,000
From growth = $682,195 (55% of FIRE number)Math grounded in the Trinity Study (Cooley et al., 1998) and Karsten Jeske's SWR Series.
