My FRA is 66 and 8 months and I intend to wait until age 70 to start claiming Social Security. I know that my benefit will increase each year for COLA. My question is this --> there are 3 years and 4 months between FRA and claiming. At 8%/year, does that mean that IN ADDITION to the COLA increases, I will also have my benefit amount increased by a total of roughly 28% or so? That would be 8% X 3, compounded, plus another 2.6% or so. Thanks for your responses.
