Start a 401k plan as early as possible. This goes for any type of retirement plan. The earlier it is established, the longer you will have to deposit money into it. Starting a 401k plan early in your career is a wise decision to make. You will be glad you did when it comes time to retire.
Educate yourself about 401ks and other retirement plans. The more you know, the better you will be able to evaluate which option is best for you.
Be involved and active in your 401k account. Know what is going on, where your money is being invested, and exactly how much is there at a time. This will help you be alert for any problems that may arise.
Find out if your employer is willing to match some or all of your contributions into your 401k account.
