Retirement
You're thinking of retiring early but not sure if you can. How much is enough? That will depend on the lifestyle you lead today and what you expect once you stop working.
Do you have a pension plan? 401K? How old are you? Do you plan to travel? Do you like to eat out often? How much debt are you carrying? Downsizing you house? Still paying for college?
CU One's retirement calculators might not answer all of your questions but they'll help you ask the right ones.
