Quick Answer

A FIRE Calculator determines your FIRE number—the savings needed for Financial Independence, Retire Early—using the 4% rule: multiply annual expenses by 25-30 for a nest egg that lasts 30+ years.[1][3][4] Input age, monthly expenses, savings rate, and returns to project retirement age and success rates via historical data from 1871-2019.[2][3] Ideal for high savers targeting 50%+ savings rates to retire in their 30s or 40s.[2][4]

Why You Need This

The FIRE movement tackles longevity risk in early retirements spanning 50+ years, where traditional plans fall short amid market volatility.[3] Key stat: Save 25-30 times annual expenses (e.g., $40,000 yearly needs $1-1.2 million) for a safe 4% withdrawal rate, backtested across 98 market cycles.[1][3][6] High savers in Lean FIRE (minimalist), Fat FIRE (luxury), Barista FIRE (part-time), or Coast FIRE (passive growth) use it to model scenarios like rentals, taxes, or downturns, avoiding the "Wedge of Death" failure zone.[3][4][7]

How It Works

Enter current age, monthly expenses (×12 for annual), current savings, monthly contributions, and expected returns (e.g., 7% post-inflation).[2][5] The calculator projects your FIRE target, retirement timeline, and success via Monte Carlo simulations or historical backtests (e.g., 1950-2000 periods).[3][6] Outputs show green zones (high success) or red zones (risk of depletion), factoring inflation and portfolio mixes like stocks/bonds.[2][3]

Tips for Best Results

  • Use realistic expenses excluding one-offs; test conservative returns and fixed withdrawals for pessimism.[2][4]
  • Aim for 50%+ savings rates; ramp investments if projections gap.[1][2]
  • Re-run for life changes like home buys or Roth conversions; delay retirement if success <90%.[3][5]
  • Track progress quarterly to boost income via side gigs or rentals for buffer.[4][7]
