Will You Need a Bigger Retirement Nest Egg?

One of the trickiest things about saving for retirement is figuring out how much money to sock away. After all, if that period is many years away, determining what your monthly living costs will look like can be difficult.

But the one thing you should always do in the course of your retirement planning is err on the side of assuming that your senior years will cost more than you think. If you don't, you may end up with a nest egg that really falls short.
