How much do you (really) need to save for retirement?

“Just how big your nest egg should be and how long it might last will depend not only on what you save and invest but also how you plan to spend money once you retire. Do you plan to work part time in retirement? Travel a lot? At what age do you plan to retire? Answers to all these questions will help you figure out how large a nest egg you may need to live the life you want in retirement. And don’t forget to factor in inflation and future market conditions.”
