The 4% Rule Explained

The 4% rule comes from the Trinity Study (1998), which found that a portfolio of 50-75% stocks could sustain a 4% initial withdrawal rate (inflation-adjusted) for 30 years with over 95% success historically. For a $500,000 portfolio, this means $20,000/year or about $1,667/month.

What Can Make Your Money Last Longer

  • Delay Social Security to age 70 — replaces $1,000-$2,000+/month of withdrawals
  • Part-time income even for 5-7 years cuts the portfolio draw dramatically
  • Flexible spending — reduce withdrawals in down-market years
  • Bond/cash buffer — keep 1-2 years of expenses in cash to avoid selling stocks in downturns

How Long Will My Retirement Savings Last?

The most important question in retirement planning: at your current withdrawal rate, how long will your savings last? This depends on three variables: your portfolio balance, your annual withdrawal amount, and your portfolio's rate of return.

The 4% Rule

The most widely cited retirement withdrawal guideline is the 4% rule: withdraw no more than 4% of your portfolio in the first year of retirement, then adjust for inflation each year. Research shows this approach has historically provided a 95%+ probability of a 30-year portfolio survival. On a $1 million portfolio, the 4% rule = $40,000/year ($3,333/month).

Portfolio Survival by Withdrawal Rate

$30,000/yr (6%)~22 years30+ years
$40,000/yr (8%)~16 years~26 years

Assumes 5% annual investment return and 3% annual withdrawal increase for inflation. Social Security income significantly extends portfolio survival — a $2,000/month Social Security benefit reduces your portfolio withdrawal need by $24,000/year.
