The TSP is one source of your retirement income.  Other major sources of retirement income include your FERS Basic Annuity or CSRS annuity (or your retired pay if you are a member of the uniformed services), Social Security benefits, individual retirement accounts (IRAs), and other savings.  To find out how much you need to save for retirement, link to the Ballpark Estimate calculator below.  The calculator was developed by the American Savings Education Council to calculate how much you need to save each year from now until retirement based on your estimates of retirement income and existing savings.
