That's great, I'll give it a try. It looks like an executable file, is that right?
I've seen/used a number of break-even SS calculators. And I've used the "maximize my Social Security" subscription software.
I think both approaches have issues they're overlooking.
(1) the break-even principle is fine but many people see SS as "longevity insurance", and I eventually subscribed to this principle. By accepting waiting to draw SS (and losing out now) there is the potential for a higher draw later...for a longer period of time. And for ones survivor as well, as they can benefit from the higher benefit due to delayed retirement credits. My spouse is 11 years younger than me so I plan to follow this approach. But every person has to investigate for their own situation and come to their own resolution.
(2) the commercial software "maximize my Social Security" (or any other non-commercial approach, as I used to do with spreadsheets) ignores the global picture. This software typically has you delay SS benefits in order to maximize benefits over a (statistical) lifetime. It is really slick software and I have the greatest regard for the author. But when you look at the entire picture, the global picture, of where your support comes from in the years where you're not getting SS then the amount of "maximizing" your SS benefit (at the detriment of other account balances on which you must draw) is greatly diminished...often to the point of virtually a wash. See, for example, the iORP software (free!) at www.i-orp.com.
Kotlikoff, author of MMSS, has other, more sophisticated software to address the issue I noted.
