What this calculator does

Enter your age, savings, saving rate, expected spending in retirement and Social Security. The calculator projects your balance year by year until your chosen life expectancy and shows the age at which savings would run out, if they do. It is arithmetic on the numbers you enter, not a prediction of markets.

The starting values on this page are examples, not recommendations: age 35, retire at 65, plan to 85, $50,000 saved, $75,000 income, 10% saved each year, a 7% return, 3% inflation, $60,000 a year of spending and $20,000 a year of Social Security.

Three assumptions to explore

  • Return. A constant return is a simplification. Real returns vary from year to year, and the order matters once you withdraw money. See the same returns in three different orders.
  • Inflation. Retirement spending rises with inflation each year, so a higher inflation rate means a larger withdrawal each year. Enter spending and Social Security as amounts for your first year of retirement; inflation is applied from the second year on, and nothing is inflated before retirement. With the starting values ($60,000 spending, $20,000 Social Security) the first year's withdrawal from savings is $40,000, and $41,200 in the second year at 3% inflation.
  • Life expectancy. Planning to a later age means more years to fund. Try planning to a later age than you expect to need; the calculator will show the effect.
