Yearly Retirement Expenditures

TIP$TER simulates an investor's financial plan on the assumption that the investor's yearly retirement expenditures will be supported by a combination of Social Security, other user-specified sources of retirement income, and draws from the investor's retirement portfolio.  Consequently, when TIP$TER reports an investor's "retirement expenditures" for a given year or span of years, the value includes the investor's Social Security income and other specified retirement income.
