I retired at 54 and at the time I looked at My Social Security for my estimated benefits amount I would be able to draw on. I understand it estimates this amount if I continued to work until 62/67/70. I am now 58 and the estimated benefits shown have risen but I haven’t contributed to the social security In 2016/17 or 2018. So the estimated benefits I pulled up today is it correct or is there a formula to calculate the projected income in the future from SS?
