Give me a museum and I'll fill it. (Picasso) Give me a forum ...
([1+(8%*4)]/[1+(8%*3)])-1 = (132/124)-1 = 6.45% = the growth in the benefit from age 69 to age 70.
It is because the 8% is simple growth and not compound growth.
IOW, the 132 is 100 + (8%*4) if it were compounded it would be 100 * (1+8%)^4 or 136. It is what it is.... it doesn't make the decision any different because at the end of the day it is still good deal compared to the pricing of commercially available inflation adjusted annuities.
And for the record, where I said 8% for 4 years I was just trying to explain how the 132 was computed for those who may have thought the 8% was compounded. I recall that way back when I initially thought and would have expected it to be compounded but I learned that it is simple interest.
