I am revising what I am asking. How do you calculate SS for a person who did not have SS previously but started working in the US later in life. Many of the quick calc makes assumptions probably basing your past earning on your current earning. A more accurate method is to grab your SS earning, but tools like ssa.tools require the PIA. I may look into a spreadsheet method with some estimated numbers.Let's say you are a person who started earning SS late, for example someone who recently immigrated to the US with a green card and plan to stay in the US, what would your retirement strategy be. Would you receive any social security for working 20 years instead of 40 years? Would you just maximize investing using existing asset and higher saving to compensate for the lower SS?
UPDATE
The following video describe how to do this in a spreadsheet. Note that bend point changes year by year.

This at least give me a rough initial estimate of what to expect for SS.
UPDATE 2
OK, I foun another way to get a semi-accurate estimate quickly.
- Go to the quick calculator at https://www.ssa.gov/OACT/quickcalc/index.html
- Filled out the form. For this example, I used a person borned in 6/15/1980 and then retire after 67 years and currently making $30K. The claim is that this person will have $1,327 upon retirement.
- You should see a button "See the earnings we used". Click on the button.
- You should see your back salary all the way back when you are 18 estimated. In this person's case, we zero out everything except the last entry because the person had no US earning perviously and click on submit. Now the amount drops to $1,244. Note that this is still assuming you will make $30K from now on with no increase and that you will have worked enough to claim SS.
