How Long Will You Live?

Calculators offer many methods for estimating life expectancy.

Your estimated life expectancy impacts many retirement planning decisions. Financial planners use life expectancy to make recommendations on when to start Social Security payments, or if an annuity makes sense for you. Insurance companies estimate life expectancy to make smart financial decisions on the types of insurance they issue - and who they issue it to.

You can use life expectancy calculators to estimate your own and a spouse's life expectancy. This can improve your planning decisions! Here are four resources you can use to come up with some estimates. The life expectancy tables and calculators below are listed in order of the simplest to the most advanced methods of estimating life expectancy.
