The new TSP site talks of the Expenses and Fees here:https://www.tsp.gov/tsp-basics/expenses-and-fees/ and doesn't specifically use any terms in how often these feesl are taken out. I'm guessing its annual by the way it talks of 2022 such as: "This first table shows, for each of the TSP individual funds, the 2022 gross administrative expense ratio....."
But its not clear and I don't like to assume. I absolutely hate this new TSP site. It juat seems so under handed and scammy.
