Financial life expectancy calculates how many years your current savings will fund your lifestyle based on withdrawal rates and investment returns. This concept is crucial for retirement planning, early retirement considerations, and financial independence decisions. The fundamental question: will your money outlast you, or will you outlast your money? Understanding this projection enables course corrections before running out of assets.

The calculation involves three primary inputs: current savings/investment balance, annual withdrawal amount (living expenses), and expected investment return. A simplified example: $500,000 saved, $30,000 annual expenses (6% withdrawal rate), and 5% investment return. At this rate, the savings last approximately 25 years. However, this assumes constant returns and expenses—real life presents more complexity with market volatility, inflation, and changing spending needs.

The "4% rule" in retirement planning suggests withdrawing 4% of initial portfolio value annually, adjusted for inflation, provides high probability (90%+) of not outlasting savings over 30 years. This rule, derived from historical market performance analysis, implies needing 25x annual expenses saved for retirement (100% ÷ 4% = 25). However, early retirees face longer time horizons requiring lower withdrawal rates (3-3.5%), meaning 28-33x expenses saved.

Sequence of returns risk poses the greatest danger to financial life expectancy. Market losses early in retirement can permanently impair portfolio sustainability even if long-term average returns meet expectations. A retiree experiencing a 30% market drop in year one and withdrawing expenses simultaneously suffers a double hit that's difficult to recover from. This argues for maintaining cash reserves (1-3 years expenses) separate from investments to avoid forced selling in down markets, extending financial life expectancy despite slightly lower overall returns.

Your financial runway is how long your money would last if you stopped earning income today. It's calculated by dividing your net worth by your monthly burn rate (expenses minus passive income). This number is crucial for understanding your financial security, planning career transitions, or evaluating early retirement readiness.

For example: If you have $250,000 in accessible savings and spend $4,500/month with no passive income, your runway is 55.5 months (4.6 years). If you cut expenses to $3,000/month, your runway extends to 83 months (6.9 years) - adding 2.3 years without earning any more money.

This tool helps you visualize your financial security, identify ways to extend your runway through expense cuts or part-time income, and understand what it takes to reach financial independence.

Higher income doesn't automatically mean longer runway if you spend it all. Many high earners have shockingly short runways due to expensive lifestyles.

Andy earns less but has 3x longer runway! The key is the gap between income and spending, not income alone. Control your burn rate to maximize runway and build wealth faster.

You don't need a full-time job to dramatically extend your runway. Even small amounts of income have outsized effects.

This is the "Barista FIRE" concept: work part-time to cover most expenses while your investments continue growing. Just 20 hours/week nearly doubles your runway from 4.6 years to 8.3 years!

If you're selling investments to fund expenses, market timing matters enormously. Bad market years early in retirement can devastate your runway.

Solution: Keep 1-2 years of expenses in cash or short-term bonds. This lets you avoid selling stocks during market downturns, protecting your runway from sequence of returns risk.
