The FIRE Movement
The FIRE movement (Financial Independence, Retire Early) has transformed how millions think about money. The math is simple: save 25x your annual expenses, withdraw 4% annually, and your money lasts 30+ years (Trinity Study, 1998). A 50% savings rate means FIRE in 17 years regardless of income. Mr. Money Mustache retired at 30. This calculator maps your path to financial independence.

The 4% Rule (Trinity Study)
The Trinity Study (1998) analyzed U.S. stock and bond returns from 1926-1995. A 4% initial withdrawal rate, adjusted for inflation annually, succeeded in 96% of 30-year periods. For early retirement (40+ years), use 3.25-3.5% to improve success probability.
The study tested 50/50 and 75/25 stock/bond allocations. Success = portfolio not depleted over the period.
25x Expenses Rule
FIRE Number = Annual Expenses ÷ 0.04 (or ÷ your safe withdrawal rate). $50K/year × 25 = $1.25M. This is the inverse of the 4% rule: 1 ÷ 0.04 = 25.
Coast FIRE
Invest enough early so compound growth reaches your retirement goal without further contributions. Example: $250K at age 30 growing at 7% for 30 years ≈ $2M at 60. You can reduce or stop saving and "coast."
Formula: Future Value = PV × (1 + r)^n. No additional contributions needed after reaching coast number.
Barista FIRE
Partial independence: portfolio covers basics, part-time work provides supplemental income and benefits. $1.2M at 4% = $48K; add $20K part-time = $68K lifestyle without full-time employment.
Benefits: health insurance from employer, social connection, reduced sequence risk by lowering withdrawal rate.
Sequence of Returns Risk
Poor returns in the first 5-10 years of retirement can permanently damage your portfolio. Withdrawing during a crash locks in losses. Mitigation: bond tent, 2-3 year cash buffer, flexible spending, or 3.25-3.5% initial withdrawal.
- • Bond tent: increase bonds 5-10 years before retirement, then reduce
- • Cash buffer: 2-3 years of expenses in cash/short-term bonds
- • Dynamic withdrawal: reduce spending when portfolio drops
Lean vs Fat FIRE
Lean FIRE: $30-40K/year expenses, $750K-1M target. Fat FIRE: $100K+/year, $2.5M+ target. Your savings rate and timeline determine which path fits.
| Type | Expenses | FIRE Number |
|---|---|---|
| Lean | $30-40K | $750K-1M |
| Traditional | $50-80K | $1.25-2M |
| Fat | $100K+ | $2.5M+ |
Tax Optimization
Roth conversion ladder, tax-loss harvesting, and asset location (tax-inefficient in IRA/401k) can reduce taxes in early retirement. Plan a bridge strategy to access funds before 59.5.
Roth ladder: convert traditional IRA to Roth in low-income years, wait 5 years, withdraw contributions tax-free.
Healthcare Planning
ACA marketplace, HSA maximization, and geographic arbitrage. Budget $1,000-2,500/month; healthcare inflation often exceeds general inflation by 2%+.
HSA: triple tax advantage — deduct contributions, tax-free growth, tax-free withdrawals for medical. Best retirement account for early retirees.
