DISCLAIMER: This calculator is provided for informational purposes only. It is not intended to be used as an investment advisory tool or as a guarantee of a final account balance. Please note that the results shown at the end of this calculator assume that elected contributions are made for the entire year. Results do not take into account the following Internal Revenue Code (IRC) limits: elective deferral, section 415(c), and catch-up contribution. These limits, which may change every year, determine the maximum annual amount that you and/or your employing agency can contribute to the TSP on your behalf. You can view the current year's limits on the TSP website under Current Limits and Rates.
