Will your savings last to age 100? Compare your savings and income with your monthly expenses, and see how long the money lasts and what return you need.
How this calculator works
Each year of retirement, the calculator adds up your expenses, raised by inflation every year, and subtracts your income. Social Security rises with inflation, while pension and other income stay flat, as most pensions do. The shortfall is taken from your savings at the start of the year, and whatever is left grows at your expected return. It then works backward to find the savings you would need at retirement, the return you would need, and the highest monthly expenses that would let the money last to your chosen age. Many retirees hold a mix of stocks and bonds, so returns of 4% to 7% a year are common planning assumptions, lower than the long-run stock market average.
Common questions
How long will my retirement savings last?
It depends on your savings, your expenses after guaranteed income like Social Security, your investment return, and inflation. Enter your numbers above to see the age your money runs out, or what is left at 100.
What return should I assume in retirement?
Many retirees hold a mix of stocks and bonds, so 4% to 7% a year is a common planning range. The table above shows how long your money lasts at several different returns.
Does inflation really matter over 40 years?
Yes. At 3% inflation, prices roughly double every 24 years, so expenses of $5,000 a month at 60 becomes about $10,000 a month by 84. The calculator raises your expenses by inflation every year.
