Consider all your income sources
First, figure out how much you stand to receive from Social Security. The amount you receive will depend on your earnings history and other unique factors. You can elect to receive retirement benefits as early as age 62, however, doing so will result in a reduced benefit for life. If you wait until your full retirement age (66 or 67, depending on your birth date) or later (up to age 70), your benefit will be higher. The longer you wait, the larger it will be.2
You can get an estimate of your retirement benefit at the Social Security Administration website, ssa.gov. You can also sign up for a my Social Security account to view your online Social Security statement, which contains a detailed record of your earnings and estimates for retirement, survivor, and disability benefits. Your retirement benefit estimates include amounts at age 62, full retirement age, and age 70. Check your statement carefully and address any errors as soon as possible.
Next, review the accounts you've earmarked for retirement income, including any employer benefits. Start with your employer-sponsored plan, and then consider any IRAs and traditional investment accounts you may own. Try to estimate how much they could provide on a monthly basis. If you are married, be sure to include your spouse's retirement accounts as well. If your employer provides a traditional pension plan, contact the plan administrator for an estimate of that monthly benefit amount.
Do you have rental income? Be sure to include that in your calculations. Might you continue to work? Some retirees find that they are able to consult, turn a hobby into an income source, or work part-time. Such income can provide a valuable cushion that helps retirees postpone tapping their investment accounts, giving the assets more time to potentially grow.
Some other ways to generate extra cash during retirement include selling gently used goods (such as furniture or designer accessories), pet sitting, and participating in the sharing economy — e.g., using your car as a taxi service.
