After graduating from college, typically you begin a career and (hopefully) start saving for a rainy day. Years quickly pass and before you know it you might be married with children. Soon after the children arrive, you begin planning for their college. Next, you hear relatives and friends discussing retirement, and somewhere there is a distant thought about life when you will stop working. You think you have accumulated significant assets, but how do you know if there are enough? This is where retirement planning comes into play.
