The TSP has a selection of individual funds that offer broad market diversification. You can choose to have your retirement dollars invested in everything from a short-term U.S. Treasury security to index funds made up of domestic and international stocks. The TSP also offers Lifecycle (L) Funds. Each of the ten L Funds is a diversified mix of the five core funds (G, F, C, S, and I). The L Funds were designed to let you invest your entire portfolio in a single L Fund and get the best expected return for the amount of expected risk that is appropriate for you.
You may change how your money is invested by logging into your TSP account on the TSP website and making a Contribution Allocation and/or an Interfund Transfer. You can also call the ThriftLine at 877-968-3778 and follow the automated prompts. A contribution allocation specifies how you want to invest new money going into your TSP account. An interfund transfer moves the money already in your account among the TSP investment funds.
You may start, stop, or change the amount you contribute to your TSP account at any time by using myPay.
