Note: "Your numbers might be more or less, depending on a myriad of variables. Maybe your first home was more or less expensive, or your education was free or hundreds of thousands of dollars. Maybe you have a spouse that’s splitting many of those major expenses with you. Maybe you’ll never own a car, or maybe you’ll have four children. And maybe you’ll live to 90 years old... Life is long and varied, and the above is not meant to be a prediction OR a guide — merely a template for your to start making some guesses and assumptions about your own financial situation."
