Detailed Explanation

Retirement is the life phase when you’re no longer dependent on employment income. Successful retirement requires accumulating enough assets to support your desired lifestyle for 20-30+ years without a regular paycheck.

The 4% Rule

A guideline for sustainable withdrawals: withdraw 4% of your portfolio in year one, then adjust for inflation. Based on historical data, this has a high probability of lasting 30 years.

FI Number = Annual Expenses × 25 (the inverse of 4%)

Retirement Income Sources

  • Investment portfolio: Your primary source, drawn down over time
  • Social Security: Typically 20-40% of pre-retirement income for most retirees
  • Pension: If available, provides guaranteed income
  • Part-time work: Many retirees work part-time by choice

Retirement Number Calculation

  • Annual retirement expenses: $60,000
  • Retirement nest egg needed: $60,000 × 25 = $1,500,000
  • Year 1 withdrawal (4%): $60,000

Compound Growth Example

$500/month invested from age 25 to 65 at 8% return:

  • Total contributed: $240,000
  • Ending balance: $1,745,000+

Why It Matters

Retirement planning is perhaps your most important financial goal:

  1. Time Is Everything: Starting at 25 vs 35 can mean $500,000+ more at retirement-same monthly contribution.

  2. No Do-Overs: Unlike other goals, you can’t delay retirement indefinitely. Your body and mind may not cooperate.

  3. Decades of Expenses: You’re funding potentially 30 years of living without employment income.

  4. Healthcare Costs: Medical expenses increase significantly with age-Medicare doesn’t cover everything.

  5. Social Security Uncertainty: Future benefits may be reduced; don’t rely on it entirely.

Regularly tracking retirement projections and adjusting contributions ensures you stay on track for the retirement you want.
