What is retirement? How much would you need?
To me retirement is simply not having to work. You have the financial back up where you can chose to work or not. Or you simply do not need to make money might be a better way of putting it.
For that you would need no debt and a guaranteed income of $XXX..Some might be fine with $20,000 per year. Others might need $100,000+ in guaranteed, passive income.
This should be your goal.
This investment is $100,000
$2m+ in 8-10 years
