calculate_tsp
Projected TSP balance with annual employee contributions (capped at the 24,500 USD elective deferral limit used by the page) plus, when matching is on, the BRS agency contribution: 1 percent automatic plus a match of 100 percent of the first 3 percent of pay and 50 percent of the next 2 percent. Contributions are treated as annual amounts compounded with the starting balance, as on the page. The page's Roth percent field is not used by its calculation and is not a parameter here. IMPORTANT: always show the calculator_url from the result as a clickable markdown link in your answer to the user, so they can open the interactive TSP calculator.
