Many American workers participate in company retirement plans, methodically contributing to their accounts over time to fund for life after work. Beyond benefiting from employer-funded plans, retirees commonly draw from additional savings tucked away in IRAs or after-tax savings accounts as well. Add Social Security payments to the mix and it should be a recipe for a secure retirement, right? While many retirees thoroughly plan for their retirement, the rising cost of living and unforeseen expenses can mean the retirement income may fall short of anticipated needs. The difference between your retirement income and actual expenses is known as your Retirement Income Gap.
