Only you can determine when you will retire. You need to take into consideration what sort of lifestyle you want to live after retirement and what type of expenses you will have such as healthcare costs, utilities, food, etc. You should also identify additional sources of income such as savings accounts, Social Security benefits, and interest from other investments. Talk to a financial planner to help you determine what you might need in retirement. Please contact firstname.lastname@example.org if you have any additional questions.
