I began collecting SS in 1993 and used the benefits to help retire the mortgage on my rental property. According to my SS records I have contributed about $72,000 to SS since 1956 when I first received wages subject to SS taxation. As of today I have received about $355,000 in monthly benefits, over a period of 20 years, most of which is in savings earning interest. So, in my case SS has given me a tidy sum annually to invest as I don't need it for living expenses.
That sounds about right -- but is not the "Universal" experience with Soc Sec. If in all those previous years, you couldn't afford to save -- it's LIKELY that you were NO WHERE NEAR the cap. Most of us arent. But the CAP on income subject to FICA is OUTRAGEOUSLY HIGH. Higher than probably any years income you received. So the ROInvestment for MOST PEOPLE is nowhere near your calculation.
For people making somewhere near $40K/year in the 80s or 90s -- THEIR math (if they LIVE til their 80s or 90s) on ROI kinda breaks even depending on whether they were SELF-EMPLOYED or not.
In YOUR CASE -- if you were NOT self-employed -- YOUR EMPLOYER PAID a matching sum in YOUR NAME -- into the fund. Causing your 4 to 1 ROI to go to 2 to 1. And THAT came out your pocket in SOME FASHION as "overhead" on you being employed.
In my case, both wife and I were SELF-EMPLOYED for 25 years at the HEIGHT of our earnings. Our privilege was to PERSONALLY PAY BOTH 1/2s of the FICA tax on EACH of us. The system allows a little gaming in that planning for "survivors" benefits -- sometimes its good for one of couple working together to take a much LOWER salary. Thus, the SURVIVING spouse gets the LARGER SS payment.
MY ROI wont go positive until my early 90s. MOST professionals in the SAME BOAT because of the ugly HIGH salary caps that would have FDR crashing his wheelchair into the Treasury Bldg.
And when I look at what I COULD HAVE EARNED by just investing in an S&P or Russell 2000 total market fund -- I'd have EASILY twice as much to spend by my mid 80s.
They made SSec "pay as you go". Then they raise the FICA and caps sky high.
It is NOT UNIVERSAL. It's now (as FDR SAID) -- "the dole in another form".
Its INCOME REDISTRIBUTION in fact..
