The classic “4% rule” is a starting heuristic, not a guarantee. Lower rates (3–3.5%) are more conservative for early retirees with long horizons. Toggle withdrawal rate in the what-if workspace to see timeline sensitivity.

Governing formula
FIRE# ≈ AnnualSpend / SafeWithdrawalRate
Nest egg needed so a chosen withdrawal rate covers annual spending.
Example: set Annual Expenses ($) = 50,000, Current Invested Assets ($) = 120,000, Annual Savings ($) = 30,000, then read the result.

- SWR
Safe withdrawal rate
e.g. 0.04 for the classic 4% rule.
- Historical SWRs are guidelines, not guarantees.
Practical guide
Using the FIRE Early Retirement Calculator well
Who this is for
Savers estimating an independence number who want a transparent multiple of spending—not influencer mythology.
Worked example
Spending $48,000/year × 25 = $1.2M as a classic 4%-rule starting point. Stress-test higher spending or a lower withdrawal rate if your timeline is long or healthcare is uncertain.
Treat 25× as a draft
The calculator shows the arithmetic. Your plan still needs healthcare assumptions, housing flexibility, and a willingness to earn bridge income if markets are rough early on.
Common pitfalls
- Using peak-career spending as the retirement base
- Ignoring sequence-of-returns risk in early retirement
