Hey Jeff,
One thing to keep in mind is that your Social Security benefit amount increase every year from age 66 to 70 which you probable know about.

I was very fortunate with my last job prior to retirement as it was a “walk in the park” as the saying goes. I was responsible for managing a piece of software for a local trucking company and my boss did not care what I did, within reason, between keeping it up and running and all of the down time in between of which I spent on various metal working forums during the day. I guess managing boredom was my main challenge.
I will be 74 next May and retired 2 years ago as of this post and that corresponded to my wife's 65th birthday and her signing up for Social Security. I chose to start my Social Security about 2 years prior (4 years ago) to my retirement just to have a little bit extra money coming in due to my wife's early retirement due to health issues.
When I signed up for my Social Security they gave me the option of backdating my benefits start anniversary date for 6 months and then gave me a check for the difference between the 6 months ago amount and the amount I would have received now at sign up time. That check amount was for a period of 10 years if I remember correctly. So my break even point will be when I turned 80. In other words they gave me a check for the 6 months difference in the benefit amount for a period of 10 years. If I die before my 80th birthday I am still ahead in the amount of my monthly benefit check. And after that I will in essence get a smaller monthly check that reflects my 6 month early benefit date. This is probably what you were explaining at in your example, just a little more long winded for my version.
Now for a little background concerning me and my wife and our retirement planning. Neither one of us have any children and we both worked up to retirement. Brenda as a RN and me as a computer programmer as a second career starting around 1988.
We purchased our current home smallish home (about 1100 sq feet) in the early 1980's and refinanced about half way through our 30 year mortgage to a 15 year one and then started making extra monthly principal payments to pay it off early, which we did. We also decided to not buy a bigger house as our current one is quite comfortable for us and our dogs and cats over the years.
We both have a nominal guilt free monthly allowance that we can spend without hurting putting us into debt and we monitor/plan our purchases so we can pay off our monthly credit card bill.
Me and Brenda are pretty much home bodies with no desire to travel/etc and truly enjoy our individual hobbies and being able to site back and enjoy our life together. In other words life, even through these stressful times is good.
I absolutely love retirement with no regrets or longings. Its like a second childhood of an endless summer of doing whatever I want to do within reason and my allowance. During my first two years of retirement I seemed to still be on that working schedule of time of do things in a hurry as I guess it took me a few years to slowly switch to retirement time.
Best wished for a wonderful retirement!
Harry
PS
After reading the below post I decided to add a PS to mine. While index funds are a great place to park you retirement money, we decided to get completely out of the equity market and moved all of our retirement saving into CD ladders. While the interest is very little we are at a stage of life where we will probably not have the time to weather an market downturn and wanted something safe as FDIC insured CD's are insured up to at least $250,000 per CD per issuer.
