Estimate the growth of your TSP account by doing one or both of the following:
- Calculate the growth of your future contributions and earnings
- Calculate the growth of the money already in your account
Note: The FERS calculation of the growth of your future contributions and earnings includes the effect of Agency Automatic (1%) and Matching Contributions.
1. You may begin contributing to the TSP (through payroll contributions) as soon as you are hired. If you are a FERS employee, you are also eligible to receive agency automatic and matching contributions. CSRS employees and members of the uniformed services do not receive agency contributions. (For more information on eligibility for agency contributions, see "Participating in the TSP" in TSP Features (for civilians or uniformed services).
2. The maximum amount of your own basic pay that you can contribute to the TSP is limited by the IRS. IRS elective deferral limits may increase each year.
The amount you can contribute to the TSP in
catch-up contributions is also limited by the IRS. Do not enter a dollar amount that will result
in an amount exceeding the IRS limit. These limits may change each year.
