<prompt> Human: Hello,I am a very young person and Im trying to figure out how much money I need for retirement, so that I can make sure that I am on course.The problem is that Ive looked at several online calculators for this and they all use Social Security in their calculations model.I read your wiki on SS and I agree that yes, it probably wont go away and that yes, we probably will see _something_, but thats the only real bets we can make. It may very well only amount to double-digit supplements per month. Maybe its triple digits. My point is that no one knows but I know in my gut it sure as hell wont be as nice and cushy as these calculators are predicting with seemingly born-in-1950s models. It seems dangerous and irresponsible to base future fixed-income finances on something that will vary that widely.TL;DR: Are there any calculators out there that make far safer or even no Social Security assumptions?  <response>: I agree with you, but many tools online let you set your assumption for SS income manually. I usually enter 0 or 1 if it wont let me disable completely.
