The longer the timeline, the lower the risk for equity investing, based on history. Let's be clear, though. I used the assumptions in your post. You hadn't mentioned anything about risk up to that point.The projected numbers .
But risk makes those numbers uncertain and timeline length increases that variability .
Its why you can get a much lower mortgage rate for a 10 year versus 30 year-
Because the bank is taking on more risks.
I don’t find the company vs personal finance analogy compelling at all .
A company is a legal entity , whose bankruptcy impacts debtors .
Personal bankruptcy affects so much more for such a much substantially longer time .
But risk is definitely a factor. People have different risk profiles and will act accordingly. I choose a risk-averse portfolio approach because I have no need to take risks. I did take risks when I was younger because I had time to make up for bad gambles. But, again, that is a personal choice and has nothing to do with projected financial based on historical averages.
Companies and personal choices for debt are similar, regardless of whether you find it compelling. Both are using other peoples' money for their own investments.
