It's difficult to say exactly how much money you will need to retire, as it will depend on a number of factors, including your desired lifestyle in retirement, your expected expenses, and how long you expect to be retired. It's a good idea to start by creating a budget to get an idea of your expected expenses in retirement, and then use that information to help determine how much money you will need to save in order to meet those expenses.
