Today's seniors can expect a longer retirement than their parents. That means more years to finally do what you want to do, including travel and hobbies (not to mention spoiling the grandkids). But a longer retirement also means more years of money going out and no paycheck (or only a small one) coming in. That's why seniors need to be smart about how they pay for their retirement years.

"You really need to have a strategy to make sure your savings last," said Lee Bowman, National Coordinator of Community Affairs at the FDIC.

To help you set or adjust your own plans for affording retirement, FDIC Consumer News offers this look at some different sources of money, including some potential pitfalls to avoid. But first, remember that this is general guidance only. Your own need for retirement money will depend on factors such as your health-care costs or whether you plan to earn part-time income. As with any major financial decision, be sure to consult with financial advisors and loved ones to decide what strategies are best for you.
