Fidelity says that the average 65 YO couple retiring today needs $240k to pay for health care assuming a 20 year life for the wife and 17 years for the husband. Thats an average of $12k per year. I'm budgeting 15k for ages 65 and above (and 28k from now until then). This is for 2 people.
(note: the 28k is based upon unsubsidized Obamacare premuims of 19k plus 8K for everything else --- OOP max is 11k)
Both pre and post retirement I'm hoping that I'm only average and not worse !
