Properly saving for retirement requires answering many questions. How much money do you need to save to securely retire? What products are available to accumulate enough savings? How is a 401(k) different from an individual retirement account?

What makes many of these questions tricky is the fact that the right answers depend on an individual’s unique financial circumstances. What’s true for everyone, however, is that understanding the differences between long-term retirement savings tools is key to making investment decisions that will help you achieve your savings goals and position you for financial success in retirement.
