Savings Growth & Retirement Drawdown
How It Works

This calculator projects your retirement savings in two phases:

Accumulation Phase (Working Years)

Balance grows with monthly contributions + compound returns

Real Return = ((1 + nominal) / (1 + inflation)) - 1

Withdrawal Phase (Retirement)

Annual Withdrawal = Savings at Retirement x 4%

Monthly Income = Annual Withdrawal / 12

  • All results are shown in today's dollars (inflation-adjusted)
  • The 4% rule is a widely-used retirement withdrawal guideline
  • The chart shows accumulation through working years, then drawdown through retirement
  • The "on track" indicator checks if savings can last at least 25 years in retirement

This calculator does not account for Social Security, pensions, part-time work income, or taxes. Actual results will depend on market conditions, withdrawal timing, and personal circumstances.
