Today’s Chart of the Day from JP Morgan shows the probability of how long you'll live if you reach age 65. We often hear the average lifespan is 74 years, but if you make it to 65, your odds to live past 74 are significantly higher. For instance, if you are a woman in good health, there is a 50% chance you will make it to age 90.
In financial planning we often use the average age of 95 for your “terminus” and do so because there is still a 31% chance that a woman will live that long. In addition, all of this also assumes there are no advances to healthcare in the next 30 years, which would only help the odds.
