At your age it is difficult to arrive at an exact dollar figure for retirement, but you should aim to be saving between 15-20% of your income. The earlier you start, the more likely you are to have a comfortable retirement. I would recommend meeting with a financial planner in your area, preferably a CFP or ChFC, to take a look at the options available to you for savings that will be the best fit for you finanically. If you have a 401(k) with your employer you should first aim to max out your contributions there that your employer will match. The dollar figure you are aiming to have at retirement will also depend on the type of retirement you would like to have and your expenses going into retirement. Developing an ongoing relationship with a financial planner is a good investment to make sure you meet your goals.
