Key Calculations Explained

The Rule of 25

The Rule of 25 is calculated as:

  • Annual expenses × 25 = Target retirement savings
  • Based on the 4% safe withdrawal rate
  • Designed to last 30+ years in retirement
  • Accounts for inflation and market returns

Safe Withdrawal Rate

The 4% rule suggests:

  • Withdraw 4% of your portfolio annually
  • Adjust withdrawals for inflation each year
  • Portfolio should last 30+ years
  • Based on historical market performance

Annual Expenses

Consider including:

  • Basic living expenses
  • Healthcare costs
  • Travel and leisure
  • Unexpected expenses

Important Considerations

Market Conditions

The 4% rule assumes average market returns. In periods of poor market performance, you may need to adjust your withdrawal rate.

Inflation

Your expenses will likely increase over time due to inflation. Consider this when planning your retirement savings target.

Lifestyle Changes

Your spending patterns may change in retirement. Review and adjust your annual expense estimates regularly.
