Thrift Savings Plan (TSP) helps you invest for the long term by mixing a small amount of money with a lot of investment-grade securities.

You can save up money for a goal, and then invest it in a portfolio of low-cost, market-leading securities. The more successful your investment portfolio is, the more you’ll earn on your savings.

How to get started

If you’re new to investing, you’ll need to set up an account with a financial advisor.

When you create an account with a financial advisor, you’ll pay a fee to that advisor. The fee varies by financial advisor, but is usually around $30.
