One of the most effective ways to accumulate a large retirement nest egg is to start young. And no age is too young. In fact, the younger the better. Even a one year-old can make an IRA, or better yet, a Roth IRA, contribution as long as they have earned income – perhaps as a model in a Gerber Baby Food commercial. In reality though, most people don’t start contributing to retirement accounts until much later on in life.
