617 | The Hidden Assumption in Every Retirement Calculator

About this episode

Most retirement calculators assume your money needs to last until age 95. But if you're 55 years old today, average life expectancy is actually 79 for men and 82 for women. This single hidden assumption could mean the difference between retiring five years earlier or leaving millions unspent.
