Lifetime Income vs. Lump Sum Payouts: You May Live Longer Than You Think

My parents are in the midst of planning their retirement payout structure. I don’t know about everyone else, but in my mind I tend to plan to live to pretty much exactly age 80. Early death is depressing to think about (even though I have term life insurance), but what about the other end? The Statistical Ideas blog had a timely post about longevity risks and lump-sum payouts which contained a “death table” (horrible name) for people born in 1950. I’m going to paraphrase the explanation in a way that makes more sense to me.


  • Out of every 100 people born in 1950, roughly 1/3rd are expected to die by age 65. (Blue)
  • If you are in the group alive at 65, your life expectancy is now age 79. That is, half of that group will die before 79. (Green)
  • But, that also means you have a 50% chance of living past 79. If so, you will live to somewhere between 80 to 110. In other words, possibly a really long time! (Red)

If you are a couple, then the odds of at least one of you living a really long time is even higher. Let’s take a couple, one male and one female, who are both age 65. According to this Vanguard longevity calculator, there is an 89% chance at least one will reach age 80, and a 45% chance at last one will reach age 90. If you are younger, your life expectancy is even longer; enter your age(s) into the calculator.

Here’s my mental shortcut. For an individual that is 65 today, there is roughly a 50/50 chance they will reach age 80. For a couple both at 65, roughly a 50/50 chance that at least one person will reach age 90. Putting it this makes make either scenario equally likely and would push me to plan accordingly. On one side of the coin flip, you have to enjoy life now! On the other side, you need to be prepared.

This longevity risk needs to be accounted for when you give up pensions or annuities that offer you a guaranteed income for life. A lump sum payout may sound attractive, but be very careful. Have any annuity and pension buyout offers analyzed and checked by an unbiased third-party. It is a big decision and may be worth paying an expert for their time.

Here’s a sad story of lowball buyout offers for lead-paint victims. Not to say all lump-sum offers are this bad, but it serves as a warning to make sure you understand what you are giving up.
