Figuring out how long you can expect to live is important for planning your retirement and how much you should be saving. You don't have to just pull a number out of the air though. This calculator estimates your expected life span based on medical research and your own unique health factors.
The Living to 100 Life Expectancy Calculator is offered by the Boston University School of Medicine. It's based on the largest study of centenarians and their families, as well as other longevity studies.
The calculator asks you 40 questions covering things like your nutrition, family history of diseases, sleep patterns, and even results from your last checkup, such as cholesterol and blood pressure readings. Then you get the magic number as well as estimates of how tweaking different things in your life could increase your life expectancy.
Obviously, we can't know for certain exactly how long we will live, but this tool can help you plan your finances better and make better health choices.
Note that you'll need to register with an email address at the end of the quiz to get your results.
