Saving 1% more really makes a difference

It's all about compounding "Compounding is basically a way of earning interest on interest. When you invest money, be it in stocks, bonds, or a savings account, if all goes well, you make some money on whatever amount you initially put in. When that happens, you can then invest your profits again, kicking off a virtuous (and lucrative) cycle of accelerating gains.
What does compounding have to do with retirement? It's simple: The earlier you start putting money into a 401(k) or IRA, the more time you get to take advantage of compounding. Similarly, the more money you contribute up front, the more you stand to earn on that money."
