Frequently asked questions

What's the FIRE number for retire at 60 with traditional fire math?

FIRE number = annual expenses × (100 / SWR). For $70,000/year expenses at 4% SWR: $70,000 × 25.0 = $1,750,000.

How many years to reach this FIRE number?

Starting with $200,000 and saving $2,000/month at 7% real return, you reach $1,750,000 in 20 years at age 60. Total contributed in the simulation: $680,000; growth: $1,077,829.

What savings rate does this require?

$24,000/year saved out of an implied $94,000 income = 26% 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 25 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)
             = $70,000 × 25.0
             = $1,750,000

Years to FIRE: solve   bal × (1 + r) + annual_contrib = FIRE
  starting bal = $200,000
  annual_contrib = $24,000
  r (real return) = 0.07
  → 20 years (age 60)

Total contributed  = $680,000
From growth        = $1,077,829  (62% of FIRE number)

Math grounded in the Trinity Study (Cooley et al., 1998) and Karsten Jeske's SWR Series.
