Pro Tips

  • True cost of retirement spending: Set the amount to $1 to see its real value at retirement. At 10% growth over 35 years, $1 today grows to ~$28 nominally — every dollar you spend now carries that hidden price tag in forgone future wealth.
  • Nominal vs. real value: The green figure is your future dollar amount; the blue is what it's worth in today's purchasing power. Always plan retirement income using the real (blue) number — nominal figures overstate your actual buying power.
  • Compare growth rates: Run the calculator twice — once with a savings account rate (~4%) and once with a market rate (~10%). The gap over 35 years is staggering and makes the case for investing over hoarding cash.
  • Rule of 72: Divide 72 by your real growth rate to estimate how many years until your purchasing power doubles. At 10% nominal growth and 2% inflation your real rate is ~7.8%, meaning real wealth roughly doubles every 9 years.
