@ican711nm,
Quote:(1) Social Security taxes at 15% of your income.
False assumption #1... SS is NOT 15% of your income even today.
FICA is 15.3 but Medicare makes up 2.9 of that. SS is only 12.4% of current income. (Currently less with the 1 year reduction.)
So you use a figure that is too high today.
But you can't even use 12.4% for your 44 years of work.
The 12.4% includes disability insurance as well as SS.
The actual rate for SS is 10.6% with Disability Ins at 1.8%
And that is only the rate since 2000. Before that it varied and 44 years ago in 1966 was at 7%.
Quote:
(2) Your annual income is $50,000 from age 21 to 65 = 44 years.
False assumption #2. The $50,000 income wouldn't be paying SS on the entire amount for much of those 44 years.
In fact it isn't until 1992 that someone making $55,000 would pay SS on every dollar they earned.
In 1966 you would have only paid SS on the first $6,600 you earned so you would have paid a whopping $462 dollars into SS.

If you retired in 2007 and earned the max under SS every year from 21 to 65 and got 3% interest on that amount, you would only have $299,666.17 total in savings when you retired.

And it looks like I calculated you working from the age of 20 - 65.
I don't know of too many 20 year olds that would have been making $4800 in 1966. The minimum wage was $1.25.
