Any personal savings you have outside of the Thrift Savings Plan are non-TSP savings. Enter the current balance of your non-TSP savings. The non-TSP savings amount that you enter may include savings from different sources such as your savings account(s), non-TSP mutual funds, and non-TSP retirement funds (private sector 401-Ks, Individual Retirement Accounts, etc.). This value will be used to project future savings rates and your estimated final non-TSP savings at retirement. The summary result will show in current dollars and future (inflated) dollars.
Also, if you know of any additional non-TSP money you may be saving annually, enter this amount in the Additional Annual Savings box.
