Devin, my case is slightly different. I was born in 52 and my non working wife in 54. My FRA amount from last year was $2,753*. I wanted to wait until 70 to claim but wife's stops at 66, so my 8% a year increase drops to 5.33% when combined. This looks less attractive though there is still a benefit that my wife with a better family history will outlive me and claim my high age 70 amount when I pass. I watched your video and think this is correct.
* not sure how I can check this FRA amount my statement balance changed before and after April 2018
Thanks
Mike
